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, /usr/local, /opt and /tftpboot (tar and scp to another machine or use either of: /triumfcs/trshare/midas/Disks/rsync_all_NIS.csh or /triumfcs/trshare/midas/Disks/rsync_all_noNIS.csh)
  • NIS only: ascertain NIS domain name (use authconfig) e.g. "DAQ-NIS","MUSR-NIS" etc.
  • check existing partition sizes on machine: df -hl, fdisk -l
  • note which are the /home1 and /data partitions
  • if /home1 is inside the "/"partition you must save it also
  • 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)
  • 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
  • two questions will be asked: how to partition the disks and the root password. The rest of the installation is automatic.
  • select "Custom partioniong". You can create either simple normal partitions if you have only one disk or RAID 1(mirror) for / and /home1 if you have two disks. 
       <strong>For the case of one disk only</strong>: - no "/boot" filesystem,
   - allocate at least 20 GBytes for "/" filesystem (primary partition, hda1)
   - allocate at least 8 GBytes for swap (primary partition, hda2)
   - allocate the rest as /home1 and /data (primary partitions hda3 and hda4)
<strong>For the case of two or more disks:</strong>
- If there are already some partitions on the disks, consider DELETING them all 
- Click New, select software RAID for /dev/sda, 20000MB (20 GB) and Force primary partition
- Same as above for /dev/sdb
- Click RAID, select create a RAID device /dev/md0, mount point /, RAID Level1 (mirror)
- Repeat for the swap partition (/dev/md1, make it at least 8 Gbytes)
- Leave the rest of the disks free. The other RAID partitions will be created AFTER installation.
  • enter the root password for the new system
  • continue with installation, at the very end, the system will ask you to reboot
  • boot newly installed system and answer the few questions for SL5
  • Firewall: Leave it disabled; SELinux: choose Disabled; KDump: Leave it disabled; Date and Time: Leave kickstart defaults (should be NTP using TRIUMF time servers)
  • Create user: not necessary if you are using NIS; Sound card: ignore possibly.
  • The system will reboot again.

Configure SSH

  • 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
  • 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 RAID arrays

NOTE1: For compatibility with the SL6 installer, use "fdisk -u" when creating new partitions.

NOTE2a: For 3TB disks, GPT partitions are required - use "gparted" (yum install epel-release; yum install gparted), create GPT partition in Device->Create partition table->Advanced->Select->gpt->Apply. Do NOT use "parted".

NOTE2b: (NOT TESTED YET) For 3TB disks, GPT partitions are required - use "gdisk" (yum install epel-release;yum install gdisk).

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).

A typical disk layout looks like this: 

[root@ladd06 ~]# fdisk -l  ### use "fdisk -lu" instead!!!

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 : double the amount of physical RAM or bigger. If it turns out to be too small, one can add swap space by adding a swap file located on the data partition.
  • /dev/md2 : "/home" : user home directories 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. 100GB seems to be reasonable.
  • /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, follow these instructions:

  • create the partitions using fdisk or similar (this example creates a 60 GB partition):
    • fdisk -u /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
  • Check the newly created partitions: fdisk -lu /dev/sda; fdisk -lu /dev/sdb
  • mdadm --create /dev/md2 --bitmap=internal -l 1 -n 2 /dev/sda3 /dev/sdb3
  • Check the progress of building the RAID with: more /proc/mdstat
  • When finished: mkfs -j /dev/md2; tune2fs -i 0 -c 0 /dev/md2
  • mkdir /home1
  • Add to /etc/fstab: "/dev/md2 /home1 ext3 defaults 1 2" ### could be ext4 is SL6
  • 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
  • (SL5.5 or newer) enable raid1 bitmap files, for each /dev/mdX device, run "mdadm --grow --bitmap=internal /dev/mdX". In /proc/mdstat, verify that there is a "bitmap" entry. This will fail if the md device resync is in progress, so you have to wait for raid1 resync to finish.

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

  • edit ~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
  • in /etc/sysconfig/network, set "HOSTNAME=" (set it to blank to use hostname from DHCP)
  • in /etc/sysconfig/network, 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
  • chmod a+r /var/log/messages
  • disable selinux: edit /etc/sysconfig/selinux, change line to read: SELINUX=disabled

Configure NIS and AUTOFS

  • ###run "system-config-authentication", check "select NIS support", click on "configure NIS", set NIS domain, leave NIS server field blank.
  • run "authconfig --enablenis --enablepreferdns --nisdomain LADD-NIS --update"
  • (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)
  • (if needed) To setup NIS slave server:
    • check if /usr/lib64/yp exists. If not, run "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
    • add the new machine to /var/yp/ypservers on the NIS master, run "make -C /var/yp" and also "cd /var/yp; yppush -h newmachine ypservers"
    • If using securenets on the NIS master, remember to copy this file to the new slave server in /var/yp
  • (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"
  • 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 time

Verify time and date configuration. Run "ntpstat", it should say "synchronised to NTP server (142.90.x.y). If not:

Configure system updates

  • (do not do this) enable automatic system updates: run "/triumfcs/trshare/olchansk/linux/triumf-update/yum-setup.perl -o"
  • (do not do this) enable automatic kernel updates: run "/triumfcs/trshare/olchansk/linux/triumf-update/yum-setup.perl -k -o"
  • (experimental, do not do this) /triumfcs/trshare/olchansk/linux/triumf-update/yum-autoupdate.sh

Configure system services

  • chkconfig --list | grep on | sort (to see enabled services)
  • disable unwanted services:

Configure external package repositories

  • yum install elrepo-release epel-release

Configure TRIUMF packages

(TRIUMF kickstart usually installs this automatically)

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
  • 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

Enable User Disk Quotas

[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
  • 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 40000000 20000000 0 0 /home1 ### set quotas for 40GB soft and 20GB hard
  • edquota -t ### change soft quota time limits

Enable NFS V3 server

  • edit /etc/hosts.allow, add or uncomment "mountd: 142.90.0.0/255.255.0.0"
  • create /etc/exports, e.g. "/home1 @daqmachines(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

Enable NFS V4 SERVER (SL6)

  • 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

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.

Finish installation

  • logout and reboot the computer to have all the changes to take effect
