Notes
- these instructions are periodically updated to include items needed for older/newer versions of Linux. They are marked like this: (SL4.2+) means Scientific Linux 4.2 and newer; (SL4 is equivalent to FC3). (FC5 only) means Fedora Core 5; etc.
- obsolete items are marked by the "#" sign at the beginning of the line and sometimes have a comment about the reason for removal.
- typically, we do not "upgrade" machines using the Red Hat "upgrade" function. Instead, we save critical files from the old installation and do a "fresh install" from scratch
Preparation
- save /etc, /var, /root, /opt, (if needed: /usr/local, /tftpboot) by rsync to some data disk (/ladd/data0/root)
- check that "/" partition (it will be overwritten) is different from /home1 and /data partitions
- note the MAC addresses of all network interfaces, add them to ladd00 dhcpd.conf to enable PXE boot into the SL "network installer"
- shutdown
Running SL installer
- Start installation of the new system:
- IMPORTANT: if you have WDC "advanced partitioning disks" (4kB sectors), disks have to be repartitioned before use, see special instructions (TBW) (note: use fdisk -H 224 -S 56 /dev/sdx)
- (NOT AVAILABLE ANYMORE) boot from latest "SL5 kickstart" CD from Kelvin Raywood or PXE boot the latest SL installation image. after the system enters graphical mode, one can remove the CD- the installation is running over the network
- boot from ladd00 PXE server - after power up, during BIOS POST, press BIOS "boot selection menu" key (F8, F12, etc). The MAC of the network interface should be listed in the ladd00 dhcpd.conf file. In the PXE boot menu, select SL6x-64 kickstart install.
- linux will boot into the graphical installer
- two questions will be asked: how to partition the disks and the root password. The rest of the installation is automatic.
- to partition the disks, select "Custom partioning":
- If using a single SSD (30 or 60 GB), use whole disk for "/" partition (no swap partition)
- If using single HD, create 4 primary partitions (see below)
- If using dual HDs (should be same size), create 4 "RAID1" (see below) (DO NOT USE LVM)
- Use these partition sizes:
- "/" - 40GB - md0 or sda1
- swap - 32 GB - md1 or sda2
- "/home1" - 100 GB - md2 or sda3
- "/data" - remaining disk space - md3 or sda4
- if installer asks questions about boot loader, accept default settings
- package installation will proceed automatically
- when finished will ask "press button to reboot"
- boot newly installed system
- if installing without a kickstart, some questions need to be answered:
- Firewall: disabled
- SELinux: disabled
- KDump: disabled
- Date and Time: leave kickstart defaults (should be NTP using TRIUMF time servers)
- Create user: skip - will be handled during post-installation
- The system will reboot again
- after the final reboot, login as root and proceed with post-installation.
Configure SSH
(+CentOS7)
- Login from the console
- restore the SSH keys from backup (/etc/ssh/*key*)
- service sshd restart
- ssh into the new machine as root
- ssh root@localhost, ctrl-C
- ### this is done later from Konstantin's git repository - scp root@ladd00:/root/authorized_keys ~root/.ssh/
- (not needed for SL5.5 kickstart) check that /etc/ssh/ssh_config contains "ForwardX11 yes" and "ForwardX11Trusted yes":
echo " ForwardX11 yes" >> /etc/ssh/ssh_config echo " ForwardX11Trusted yes" >> /etc/ssh/ssh_config
Configure disks, partitions, raid arrays and filesystems
NOTE1: For compatibility with the SL6 installer, use "fdisk -u" when creating new partitions.
NOTE2a: For 2TB disks or bigger, use "gdisk" to create GPT partitions (yum install epel-release; yum install gdisk)
NOTE2c: (SL6) 3TB, 4TB, 6TB disks do not require anything special - proceed with installation as normal.
Typical disk configuration for DAQ use has 2 large disks with system ("/"), swap, home and data partitions, fully mirrored across the 2 disks using RAID1 software raid (MD).
In this fully mirrored configuration, a DAQ system will continue to operate without interruption and without performance degradation when there is a full or partial failure of either of the two disks.
If disks are hot-swappable, the failed or defective disk can then be physically replaced by a spare, the spare disk can be partioned and added to the RAID1 array, restoring full normal operation, without shutting down or rebooting the system or interrupting data taking. (Since SATA, eSATA and USB are always electrically hot-swappable, disk hot-replacement is more of a mechanical issue).
For small disks using traditional partitions (<=2TB) a typical layout looks like this:
[root@ladd06 ~]# fdisk -l ### use "fdisk -lu" instead!!!

Filename Type Size Used Priority
/dev/md1 partition 32766900 0 -1
Typical size of partitions:
- /dev/md0 : "/" : 40 Gbytes should be sufficient. SL5 fits into an 8GB "/" and SL6 fits into a 16GB "/".
- /dev/md1 : swap : 32 Gbytes. Additional swap space can be added using a swap file located on the data disk.
- /dev/md2 : "/home1" : 100 Gbytes. User home directories backed up by the amanda site backup system. Space is limited by the capacity and capability of the backup and archiving system used to protect user data against accidental file deletion, filesystem corruption and disastrous system failures.
- /dev/md3 : "/data" : data partition uses the remaining space on the disks.
Usually, the "/" and swap partitions are created through the SL installer program. The /home and /data partitions can be created at the same time.
Otherwise, for traditional partitions (disks <2TB) follow these instructions:
- create the partitions using fdisk or similar (this example creates a 60 GB partition):
- fdisk -cu /dev/sda
- Command (m for help): n
- Command action ... p
- Partition number ... 2, 3 or 4 according to what has been defined before
- First cylinder ... default
- Last cylinder ... +60000M or default
- Command action ... t
- Partition number ... : 2, 3 or 4 according to what has been defined before
- Hex code ... : fd
- Command action ... p to check all is correct
- Command (m for help): w
- fdisk /dev/sdb and repeat as above
- Reboot the machine
For GPT partitions (disks >=2TB), do this:
- install gdisk: yum install epel-release; yum install gdisk
- gdisk /dev/sdX
- if this is a new disk, do "o" to create a blank partition table
- "n" to create new partition:
- accept default for partition number
- accept default for first sector
- for last sector, say "+40G" to create 40 Gbyte partition, accept default to use all remaining disk space
- for partition type, say "fd00" to create an mdadm raid partition
- "p" to print the partition table
- "d" to delete wrong partition
- "w" to save and exit
Typical GPT layout:
[root@isdaq01 ~]# gdisk -l /dev/sdh GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/sdh: 3907029168 sectors, 1.8 TiB Logical sector size: 512 bytes Disk identifier (GUID): D4FCDE83-12BD-4118-ACA2-702F0E2E57C2 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 3907029134 Partitions will be aligned on 2048-sector boundaries Total free space is 2014 sectors (1007.0 KiB) Number Start (sector) End (sector) Size Code Name 1 2048 83888127 40.0 GiB FD00 Linux RAID 2 83888128 150996991 32.0 GiB FD00 Linux RAID 3 150996992 360712191 100.0 GiB FD00 Linux RAID 4 360712192 3907029134 1.7 TiB FD00 Linux RAID [root@isdaq01 ~]#
- Check the newly created partitions: fdisk -lu /dev/sda; fdisk -lu /dev/sdb
- mdadm --create /dev/md2 --metadata=1.0 --bitmap=internal -l 1 -n 2 /dev/sda3 /dev/sdb3
- Check the progress of building the RAID with: more /proc/mdstat
- When finished: mkfs -t ext4 /dev/md2; tune2fs -i 0 -c 0 /dev/md2
- mkdir /home1
- Add to /etc/fstab: "/dev/md2 /home1 ext4 defaults 1 2"
- Finally mount this new partition: mount -a
- Repeat from "mkfs" for each of the data partitions
- At this point you should have these disk partitions (single-disk in parenthesis)
- /dev/md0 (/dev/sda1, sdb1) is the system partition, 40 GBytes or more
- /dev/md1 (/dev/sda2, sdb2) is the swap partition, 32 GBytes or more
- /dev/md2 (/dev/sda3, sdb3) is the /home1 partition, 100 GBytes or more
- /dev/md3 (/dev/sda4, sdb4) is the data partition
- Add array descriptions to /etc/mdadm.conf:
- mdadm -Ds >> /etc/mdadm.conf
- emacs -nw /etc/mdadm.conf ### remove duplicate entries
Example /etc/mdadm.conf:
MAILADDR root AUTO +imsm +1.x -all ARRAY /dev/md0 metadata=1.0 name=isdaq01.triumf.ca:0 UUID=055f0455:18401f41:b12abf53:2b23eca0 ARRAY /dev/md1 metadata=1.0 name=isdaq01.triumf.ca:1 UUID=dde05275:17961aaf:7c864e3a:c51477d6 ARRAY /dev/md2 metadata=1.0 name=isdaq01.triumf.ca:2 UUID=e430ba44:361f1807:41f0c491:53c10438 ARRAY /dev/md3 metadata=1.0 name=isdaq01.triumf.ca:3 UUID=a34d8c5b:cb65a435:be8ee01d:7f988927
- (SL5.5 or newer) enable raid1 bitmap files, for each /dev/mdX device: mdadm --grow --bitmap=internal /dev/mdX
Restore data from backups
- (on midm15/midm9b/midm20 only) install correct ethernet driver eepro100 not e100
- restore /home (non-NIS) or /home1 (NIS) and other required user directories from backup. (Can use /triumfcs/trshare/midas/Disks/rsync_back.csh ).
- if needed, for non-NIS only, make a softlink for /home1: ln -s /home /home1
- restore users accounts (non-NIS and NIS master only): edit /etc/passwd and /etc/shadow, append users' login info to the end of these files from the backup versions.
Post installation
- emacs -nw ~root/.forward, (create file if not present, or restore from backup) In file add email address of the person(s) to receive root's email: echo "olchansk@triumf.ca" >> ~root/.forward
- emacs -nw /etc/sysconfig/network
- set "HOSTNAME=" (set it to blank to use hostname from DHCP)
- set "NETWORKWAIT=yes"
- (not needed for SL6.1, NEEDED for SL6->6.1 update) in /etc/hosts, remove exteraneous entries - only entries for localhost and localhost6 should remain
- disable selinux: edit /etc/sysconfig/selinux, change line to read: SELINUX=disabled, reboot later for change to take effect
- chmod a+r /var/log/messages
Post installation CentOS7
CentOS 7.1 default installer will be stuck at the "create local user" screen. To proceed without creating fake local users, do: yum erase gnome-initial-setup killall Xorg
echo "olchansk@triumf.ca amaudruz@triumf.ca lindner@triumf.ca" >> ~root/.forward chmod a+r /var/log/messages
Disable "persistent network names" (DO NOT DO THIS)
/bin/touch /etc/udev/rules.d/75-persistent-net-generator.rules /bin/rm /etc/udev/rules.d/70-persistent-net.rules #shutdown -r now
Configure NIS master (OPTIONAL)
(do not use SL6.2 for NIS master)
- yum install ypserv
- domainname DEAP-NIS
- cd /var/yp
- edit Makefile
- change NOPUSH=false
- change the "all:" entry to read: all: passwd group netgrp shadow auto.master auto.home auto.local ypservers
- touch /etc/netgroup /etc/auto.home /etc/auto.local ./ypservers
- make
- inspect created NIS maps: ls -l DEAP-NIS
- chkconfig ypserv on
- chkconfig ypxfrd on
- chkconfig yppasswdd on
- service ypserv start
Configure NIS client
- run "authconfig --enablenis --enablepreferdns --nisdomain LADD-NIS --update"
- if NIS server is SL6.2, add "--nisserver=ladd00" to above command
- (not needed with --enablepreferdns above) run "sed 's/^hosts:.*/hosts: files dns/' -i /etc/nsswitch.conf" (to undo a mistake from authconfig)
- On the master NIS node (ladd00), add this new node to /etc/netgroup, and update NIS maps (cd /var/yp; make)
- Use "system-config-users" to add local user accounts
- NIS: check user accounts: run "ypcat -k passwd"
- echo "NISTIMEOUT=5" >> /etc/sysconfig/network
- echo "NETWORKWAIT=yes" >> /etc/sysconfig/network
Configure NIS client (CentOS7)
yum -y install ypbind echo "NISTIMEOUT=5" >> /etc/sysconfig/network echo "NETWORKWAIT=yes" >> /etc/sysconfig/network authconfig --enablenis --enablepreferdns --nisdomain LADD-NIS --nisserver ladd00.triumf.ca --update ypwhich ypcat -k passwd
- On the master NIS node (ladd00), add this new node to /etc/netgroup, and update NIS maps (cd /var/yp; make)
- Use "system-config-users" to add local user accounts
- enable selinux ssh key login to nfs mounted home directories:
setsebool -P use_nfs_home_dirs 1
Configure NIS secondary server (OPTIONAL)
(do this only if needed)
(do not use SL6.2 for NIS secondary server!)
- yum install ypserv
- /usr/lib64/yp/ypinit -s ladd00 (/usr/lib/yp/ypinit on 32-bit machines)
- chkconfig ypserv on
- service ypserv start
- service ypbind restart
- on the NIS master:
- add the new machine to /var/yp/ypservers, run "make -C /var/yp" and also "cd /var/yp; yppush -h newmachine ypservers"
- if using /var/yp/securenets, copy it from NIS master to new NIS secondary server
Configure NIS secondary server (CentOS7) (OPTIONAL)
Enable local NIS server, make local machine use it:
yum install ypserv /usr/lib64/yp/ypinit -s ladd00 (/usr/lib/yp/ypinit on 32-bit machines) systemctl enable rpcbind ypserv ypxfrd yppasswdd systemctl start rpcbind ypserv ypxfrd yppasswdd edit /etc/yp.conf # change "domain XXX server YYY.triumf.ca" to read "domain XXX server localhost" systemctl restart ypbind ypwhich # should say "localhost"
Punch hole in the firewall: (or "make" on NIS master will complain)
echo YPSERV_ARGS=\"-p 800\" >> /etc/sysconfig/network systemctl restart ypserv firewall-cmd --add-service rpc-bind --permanent firewall-cmd --add-port=800/tcp --add-port=800/udp --permanent firewall-cmd --reload
- on the NIS master:
- add the new machine to /var/yp/ypservers, run "make -C /var/yp" and also "cd /var/yp; yppush -h newmachine ypservers"
- if using /var/yp/securenets, copy it from NIS master to new NIS secondary server
Configure AUTOFS
- (if NIS master or standalone) check /etc/auto.* against backups, particularly auto.master if NIS master
- (if needed) add "+auto.master" at the end of /etc/auto.master
- restart autofs to use the newly configured NIS maps: "service autofs stop; service autofs start"
Configure AUTOFS (CentOS7)
yum -y install autofs systemctl enable autofs systemctl start autofs ls -l /daq/daqshare
Configure time
Verify time and date configuration. Run "ntpstat", it should say "synchronised to NTP server (142.90.x.y). If not:
- (SL6.0) rpm -vh --upgrade http://mirror.triumf.ca/rpmindex/fedora/archive/updates/12/i386/python-slip-0.2.13-1.fc12.noarch.rpm (see https://bugzilla.redhat.com/show_bug.cgi?id=720848)

- (SL6.2) yum --enablerepo=sl-fastbugs update "*slip*"
- run "system-config-date"
- check "use network time"
- enter NTP servers: time1, time2, time3
- say "OK" (if there is an error about writing config files, say "cancel")
- chkconfig ntpdate on; chkconfig ntpd on; service ntpd stop; service ntpdate start; service ntpd start
Configure time (CentOS7)
Time server ntpd was replaced by chronyd.

Configure Konstantin's scripts
(+Centos7)
mkdir ~root/git cd ~root/git git clone http://ladd00.triumf.ca/~olchansk/git/scripts.git cd scripts git pull
Configure TRIUMF mirror of yum repositories
(only for machines on TRIUMF network)
#/bin/cp ~/git/scripts/etc/triumfcs-mirror-SL6.repo /etc/yum.repos.d/ /bin/cp ~/git/scripts/etc/triumf-SL6.repo /etc/yum.repos.d/
Configure trusted ssh keys
(+CentOS7)
ssh localhost interrupt by Ctrl-C /bin/cp ~/git/scripts/etc/authorized_keys ~/.ssh/
Configure hardware sensors
- yum install lm_sensors kmod-k10temp kmod-coretemp
- sensors-detect (accept default answer to all questions - press ENTER)
- service lm_sensors restart (to reload the kernel modules)
- sensors (to see available sensors)
If no sensors are detected by standard drivers, follow motherboard-specific instructions at the bottom of this page.
Configure coretemp CPU sensors
On some machines, the coretemp driver for Intel CPU temperature sensors is not loaded after the above steps.
- sensors | grep coretemp ### number of sensors reported should be the same as the number of CPU cores
- if output is blank, add this to /etc/rc.local
emacs -nw /etc/rc.local modprobe coretemp
Configure IPMI sensors
Some machines support the IPMI interface for monitoring the hardware: fan speeds, temperatures, voltages.
- find out if IPMI is supported. Try this:
dmidecode | grep -i ipmi
if output is not blank, IPMI is maybe supported.
- install and enable IPMI software:
yum install "OpenIPMI*" ipmitool service ipmi start ipmitool sensor ### to confirm IPMI is present. If output is blank, do not go further. chkconfig ipmi on chkconfig ipmievd on service ipmi restart service ipmievd restart tail -100 /var/log/messages ### look at messages logged by ipmievd
- (CentOS7) install and enable IPMI software:
yum install "OpenIPMI*" ipmitool systemctl start ipmi ipmitool sensor ### to confirm IPMI is present. If output is blank, do not go further. --- unfinished... chkconfig ipmi on chkconfig ipmievd on service ipmi restart service ipmievd restart tail -100 /var/log/messages ### look at messages logged by ipmievd
- if ipmievd complains about SEL buffer overflow, clear it manually:
ipmitool sel list ### show ipmi messages in raw format ipmitool sel elist ### show ipmi messages in useful format ipmitool sel elist > file ### save ipmi messages into a file ipmitool sel clear ### clear all accumulated ipmi messages
- useful ipmi commands:
- ipmitool sensor -- read hardware sensors
- ipmitool sel elist -- report all accumulated messages
Configure SMARTD (CentOS7)
- edit /etc/smartmontools/smartd.conf
- in the DEVICESCAN line, remove the "-M exec ..." switch, the file should read something like this:
#DEVICESCAN -H -m root -M exec /usr/libexec/smartmontools/smartdnotify -n standby,10,q DEVICESCAN -H -m root -n standby,10,q
- edit /etc/smartmontools/smartd_warning.sh
- in the line "export SMARTD_SUBJECT", add ":$SMARTD_DEVICE" after "$hostname", it should read something like this:
export SMARTD_SUBJECT="SMART error (${SMARTD_FAILTYPE-[SMARTD_FAILTYPE]}) detected on host: $hostname:$SMARTD_DEVICE"
- run: smartd -q onecheck
- if there are smart warnings, email should be sent to root (and forwarded according to ~root/.forward)
Enable User Disk Quotas (OPTIONAL)
- read http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/ch-disk-quotas.html
- emacs -nw /etc/fstab, add "grpquota,usrquota" to filesystem options, e.g.:
[root@isdaq00 home1]# grep quota /etc/fstab UUID=5a2aefbd-45db-475e-841e-12ec89220fbd /home1 ext4 defaults,grpquota,usrquota 1 2
- cd /; umount /home1; mount /home1
- quotacheck -cug /home1
- quotacheck -avug
- quotaon -av
- quota system is now active
- increase the soft quota time limit from default 7days to 30 or 60 days: edquota -t
- set quotas for all users (see below)
- setup warnquota:
- create warnquota config file: emacs -nw /etc/warnquota.conf
# values can be quoted: MAIL_CMD = "/usr/sbin/sendmail -t" FROM = root SUBJECT = User %i@%h exceeded allocated disk quota CC_TO = "root" # If you set this variable CC will be used only when user has less than # specified grace time left (examples of possible times: 5 seconds, 1 minute, # 12 hours, 5 days) # CC_BEFORE = 2 days SUPPORT = "root" # Text in the beginning of the mail (if not specified, default text is used) # This way text can be split to more lines # Line breaks are done by '|' character # The expressions %i, %h, %d, and %% are substituted for user/group name, # host name, domain name, and '%' respectively. For backward compatibility # %s behaves as %i but is deprecated. MESSAGE = User "%i" on "%h" has exceeded the allocated disk quota.||Please delete any unnecessary files on following filesystems or|contact the system administrato r to increase your quota allocation:| SIGNATURE = --|automated email from warnquota
- note that %i@%h in the SUBJECT line do not seem to work
- create cron job: emacs -nw /etc/cron.daily/warnquota
#!/bin/sh warnquota #end
- chmod a+x /etc/cron.daily/warnquota
- touch /etc/crontab
Useful commands for managing quotas:
- repquota -a | sort -n -k3 ### show quota of all users sorted by disk usage
- edquota -u username ### open "vi" editor to change user quotas
- repquote -a | grep username ### report quota for given user
- setquota -u username 0 0 0 0 /home1 ### disable quotas for given user
- setquota -u username 50000000 100000000 0 0 /home1 ### set quotas for 50GB soft and 100GB hard
- edquota -t ### change user quota time limits
- edquote -tg ### change group quota time limits
Enable NFS server (CentOS7)
- create /etc/exports. example:
/home1 @home_export(rw,no_root_squash,async) /data1 @data_export(rw,no_root_squash,async)
- check the netgroup file
- if using NIS: check NIS netgroup: ypcat -k netgroup
- if no NIS, create /etc/netgroup: @daqmachines (deap00,,) (deap01,,) (deap02,,)
- if no NIS, edit /etc/nsswitch.conf, make the netgrooup line read: "netgroup: files"
- enable things, start them:
firewall-cmd --permanent --add-service=nfs firewall-cmd --reload firewall-cmd --list-all systemctl enable nfs-server systemctl start nfs-server systemctl status nfs
Enable NFS V3 server
- edit /etc/hosts.allow, add or uncomment "mountd: 142.90.0.0/255.255.0.0"
- create /etc/exports. example:
/home1 @home_export(rw,no_root_squash,async) /data1 @data_export(rw,no_root_squash,async)
- check the netgroup file
- if using NIS: check NIS netgroup: ypcat -k netgroup
- if no NIS, create /etc/netgroup: @daqmachines (deap00,,) (deap01,,) (deap02,,)
- if no NIS, edit /etc/nsswitch.conf, make the netgrooup line read: "netgroup: files"
- chkconfig nfs on
- chkconfig nfslock on
- service nfs restart
Then on ladd00 need to do
- ssh to root@ladd00
- edit /etc/auto.daq to add new machine...
- make -C /var/yp
Enable NFS V4 SERVER (SL6)
- if used with NIS, same as NFSv3
- if used as standalone, need to edit idmapd.conf - set the "Domain" name to the same value on NFS server and NFS slave (default automagically determined value does not always work). More TBW.
Enable AMANDA backups
AMANDA backups are already enabled by TRIUMF kickstart installs.

Disable modem-manager
The modem-manager will try to talk to any serial devices attached to USB serial ports. It assumes that those devices are modems and will send out modem-specific commands. if the devices are not modems and do not understand or do not like modem commands, well that's too bad. modem-manager is installed by the ModemManager package required by the NetworkManager package, and there is no configuration setting to turn modem-manager off.
One way to disable it is: chmod a= /usr/sbin/modem-manager
Another way to disable it is by forced uninstall: rpm --erase --nodeps ModemManager
Remember to kill the running copy: killall -KILL modem-manager
Caveat: it is not clear if modem-manager would not be resurrected by an update to the NetworkManager or ModemManager packages.

- mv /etc/X11/xorg.conf /etc/X11/xorg.conf-xxx
- nvidia-xconfig
- (SL6) reboot
- (SL5) /dev/MAKEDEV nvidia
- (SL5) restart the X11 server (Ctrl-Alt-Backspace or "killall Xorg gdm-binary")
- observe that X11 server restarts using the NVIDIA driver (big NVIDIA logo on startup)
- if needed, login as root and run "nvidia-settings" to setup dual-screen configuration, etc
Install legacy NVIDIA drivers
For old NVIDIA cards:
- GeForce FX 5500
wget http://us.download.nvidia.com/XFree86/Linux-x86/173.14.31/NVIDIA-Linux-x86-173.14.31-pkg1.run sh ./NVIDIA-Linux-x86-173.14.31-pkg1.run
- GeForce 6200 - NVIDIA Corporation NV44A [GeForce 6200]
yum install nvidia-x11-drv-304xx-304.121 --enablerepo=elrepo nvidia-xconfig rmmod nvidia killall gdm-binary login as root nvidia-settings to setup multiple displays
Install ATI/AMD drivers
- yum --enablerepo elrepo install kmod-fglrx fglrx-x11-drv
- check that /etc/X11/xorg.conf section "Device" entry "Driver" says "fglrx"
- run "amdcccle" as root to configure dual-screens, etc
Note: 'amdcccle' is a GUI, so you must run this command from within a running X session
- killall Xorg
Install Intel drivers for HD4600/Z87
SL6.5 has the required drivers for the socket 1150 machines with Intel HD4600 graphics and Z87 chipset.
ASUS Z87 WS motherboard has these video connections with corresponding Intel video port assignements, as reported by "xrandr":
- DisplayPort - DP1/HDMI1
- MiniDisplayPort - DP2/HDMI2
- HDMI - HDMI3
Due to hardware limitations, 3 HDMI monitors using 2 passive DP-HDMI adapters (and 1 straight HDMI) cannot be used.
To use 3 monitors do this:
- 1st monitor: DisplayPort - DP-to-HDMI-passive-adapter - HDMI monitor (not tried: DP-to-DP-cable - DisplayPort monitor).
- 2nd monitor: MiniDisplayPort - MiniDP-to-DP-cable - DisplayPort monitor
- 3rd monitor: HDMI - HDMI-cable - HDMI monitor
With the monitors I have (Dell 1920x1200 VGA-HDMI-DP), the software thinks that there are 4 monitors: somehow both DP2 and HDMI2 see 1 minitor each, but the hardware cannot drive 4 monitors, so everything goes blank. To fix, disable HDMI2 (xrandr -display :0 --output HDMI2 --off) and enable DP2 (xrandr -display :0 --output DP2 --auto).
How to make this configuration permanent and how to assign monitor locations (left-right, etc), you figure it out.
Manual selection of monitor, video mode and resolution
Automatic selection of monitor and video mode usually works. When it does not, configure it manualls:
- physically go to the computer
- login as root
- run "nvidia-settings" on machines using the NVIDIA driver
- run "aticonfig" on machines with the ATI/AMD driver (use "aticonfig --initial" for initial setup, and good luck with anything more complicated)
- run "system-config-display".
- In the "hardware" tab, select monitor type: "generic LCD 1280x1024" or "generic LCD 1600x1200".
- In the "settings" tab, select "1280x1024" or "1600x1200" and "Thousands of colors".
- Press "ok", the display settings application should close.
- Logout, the new login window should use the new settings.
Disable screen saver
If machine is booted without any monitor connected, current video cards to not enable any video outputs. If a monitor is connected later, there is no video image and there is no easy way to get a video image.
This can be solved by configuring X11 to always enable some video output. Because the monitor type is not known when X11 starts, one has to select some standard video mode (i.e. VESA 1280x1024) on some video output (VGA, DVI or HDMI).
Only NVIDIA cards with the NVIDIA driver (from EPEL) is supported by these instructions.
- create default xorg.conf: nvidia-xconfig
- edit /etc/X11/xorg.conf
- add monitor section for the fake monitor:
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 31.0 - 83.0
VertRefresh 59.0 - 61.0
Option "DPMS" "off"
ModeLine "1280x1024" 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync
EndSection
- add output selection in the "Device" section:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 210"
#Option "ConnectedMonitor" "DFP"
#Option "ConnectedMonitor" "CRT"
Option "ConnectedMonitor" "CRT-1"
Option "UseEDID" "no"
EndSection
- add fake video mode to the "Screen" section:
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024"
EndSubSection
EndSection
- disable screen saver and DPMS power off in the "ServerLayout" or "ServerFlags" section:
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "0"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
Finish installation
- logout and reboot the computer to have all the changes to take effect
Configure large RAID6 arrays
- connect the disks
- check the disks health
- run smart-status.perl
- partition the disks
- yum install gdisk
- gdisk /dev/sdX
- delete all partitions: o
- create new partition: n, enter, enter, enter, fd00 (default sizes, partition type fd00)
- write and exit: w
- check presence of all partitions:
- /bin/ls -l /dev/sd*1
- prepare to use an external bitmap file
- touch /md6bitmap
- edit /etc/fstab, change entry for root filesystem from: "defaults 1 1" to "defaults 0 0"
- edit /boot/grub/grub.conf, change entry "kernel ... ro ..." to "kernel ... rw ..."
- create raid array:
- mdadm --create /dev/md6 --level=6 --bitmap=/md6bitmap --raid-devices=10 /dev/sd[b-k]1
- mdadm -Ds >> /etc/mdadm.conf
- cleanup /etc/mdadm.conf
- echo "echo 16384 > /sys/block/md6/md/stripe_cache_size" >> /etc/rc.local
- echo "echo 1 > /sys/block/md6/md/sync_speed_min" >> /etc/rc.local
- source /etc/rc.local
- observe raid array rebuild:
- watch -d -n1 "cat /proc/mdstat"
