VME CPU information

Cloning USB and CF Flash boot cards

The V7805 VME CPU can run Linux from USB flash memory, V7865 VME CPU can run Linux from CompactFlash or USB flash memory. Disk size 8 GB or bigger is recommended for running SL5.5 Linux. Highest available speed grade devices should be used: 266X or better for CompactFlash, 200X or "30MB read/15MB write" for USB Flash. Also be aware that some CompactFlash and USB Flash devices have been observed to corrupt Linux filesystems within a few days of use. The specific flash memory brands and models we presently use do not see to have this problem.

When working CompactFlash memory, attach it to a USB-CF adapter and treat it as USB flash memory in the following instructions.

Clone disk using the script clone.perl

  • attach the USB flash disk to some computer connected to the LADD cluster
  • become root
  • check that correct device appears in the device list: fdisk -l
  • assume new device is /dev/sdc
  • select an Linux image that we will clone:
    • 64-bit SL6 image for V7865 VME processors: use /ladd/data1/root/lxiris01
    • 32-bit SL6 image for dual-Athlon machines: use /ladd/data1/root/ladd13
  • cd /home/olchansk/sysadm/clone
  • ./clone.perl /ladd/data1/root/ladd13 /dev/sdc
  • df -kl ### check that /dev/sdc is not mounted
  • disconnect the USB flash disk, try to boot from it.

The clone script has been tested in these configurations:

  • clone 64-bit SL6 VME CPU image to 8GB and 16GB USB flash, GRUB bootloader
  • clone 32-bit SL6 image to 500GB IDE-USB disk, EXTLINUX bootloader.

Note that the clone script has to be run from the correct directory per instructions above as it has to find and run the uuidfix script to make the destination disk bootable.

Clone disk manually

  • attach USB flash to the computer to be cloned (or any computer - we will use rsync to copy the data)
  • become root
  • check that correct device appears in the device list: fdisk -l
  • assume new device is /dev/sdX, original boot disk is /dev/sda.
  • repartition the device:
    • fdisk -H 224 -S 56 /dev/sdX
    • create one partition covering the whole device
    • set partition type 83 (Linux)
    • set bootable flag (command "a")
    • result should look like this:
[root@lxdaq09 ~]# fdisk -l

Disk /dev/sda: 8011 MB, 8011120640 bytes
224 heads, 56 sectors/track, 1247 cylinders
Units = cylinders of 12544 * 512 = 6422528 bytes

/dev/sda1   *           1        1247     7821156   83  Linux
  • /usr/bin/time mkfs.ext4 -O ^64bit /dev/sdX1 (should take about 30 seconds)
  • tune2fs -i0 -c0 /dev/sdX1
  • mkdir -p /mnt/tmp
  • mount /dev/sdX1 /mnt/tmp
  • CLONE CURRENT BOOT DISK: cd /; rsync -ax . /mnt/tmp; cd /dev; rsync -a . /mnt/tmp/dev
  • CLONE lxdaq08 32-bit boot image (V7805, V7865): cd /ladd/data1/root/lxdaq08; rsync -ax --delete-after . /mnt/tmp
  • CLONE ANOTHER FLASH DISK: cd /another/flash/disk; /usr/bin/time rsync -ax . /mnt/tmp
  • check result: run "df", new filesystem should be about as full as the original one
  • sync; cd /; umount /dev/sdX1; mount /dev/sdX1 /mnt/tmp
  • install SYSLINUX/EXTLINUX boot loader (SL5)
    • install master boot loader: cd /mnt/tmp/boot; dd if=mbr.bin of=/dev/sdX (NOTE: ***NOT** /dev/sdX1)
    • install extlinux boot loader: cd /mnt/tmp/boot; ./extlinux -i . (NOTE: notice the "./" - make sure to run the extlinux executable from .../boot, NOT the one installed in the system)
  • install GRUB boot loader (SL6) --- (NOTE: in the line below, remember to replace "/dev/sdX" with the disk name)
    • echo -e "device (hd0) /dev/sdX\nroot (hd0,0)\nsetup (hd0)\n" | grub --batch --no-floppy
  • update boot disk UUID (SL6) --- (NOTE: dumpe2fs prints the UUID of the new disk, cut-and-paste this UUID into the sed commands below)
    • dumpe2fs /dev/sdX1 | grep UUID
    • edit grub.conf: sed 's/UUID=\S*/UUID=ddc00d49-1c17-4803-ac0b-d6eb89d9e729/' -i /mnt/tmp/boot/grub/grub.conf
    • edit fstab: sed 's/UUID=\S*/UUID=ddc00d49-1c17-4803-ac0b-d6eb89d9e729/' -i /mnt/tmp/etc/fstab
  • cd /; umount /dev/sdX1
  • disconnect the new boot disk, try to boot from it.

We will clone "lxsrc" into "lxdst": 

cd lxsrc
mkdir ../lxdst
rsync -av . ../lxdst
vi etc/sysconfig/network ### change HOSTNAME and NIS domain
vi etc/nodeinfo ### change description
vi etc/yp.conf ### add "domain xxx-NIS broadcast" for the new NIS domain
vi etc/fstab ### change the "/" NFS mount-point if needed
vi etc/cron.d/triumf_nodeinfo ### change nodeinfo server name

Cloning Ubuntu NFS-Root

We will clone "lxsrc" into "lxdst": 

cd lxsrc
mkdir ../lxdst
rsync -av . ../lxdst
vi etc/hostname ### change HOSTNAME
vi etc/fstab ### change the "/" NFS mount point

Updating Linux kernel

Updating Linux kernel on USB/CF flash boot disks

  • install latest kernel: yum update
  • identify latest kernel files:
    • ls -ltr /boot | grep vmlinuz | tail -1
    • ls -ltr /boot | grep initrd | tail -1
  • edit /boot/extlinux.conf
    • duplicate the entry marked "MENU DEFAULT"
    • change file names for the first entry according to the newly installed kernel
    • remove "MENU DEFAULT" from all entries except the new one
  • reboot into the new kernel

V7805 special settings

Because of hardware incompatibility, the V7805 cannot run vanilla RedHat/SL linux kernels.

Because of hardware incompatibility, the V7805 cannot boot from 16GB USB flash. Please use 8GB USB flash media.

To run RH/SL linux, a special linux kernel has to be built with special PCI configuration:

NOTE: kernel 2.6.34.1 works, newer kernels do not seem to work.

Network boot

Explanation

Network booting of linux computers is done by, in order:

  • PXE (in-BIOS, in-EFI-BOOT or GPXE booted from disk) issues DHCP request to learn the IP address and further boot instructions
  • DHCP server (/etc/dhcp/dhcpd.conf) responds with the IP address and instructions to boot pxelinux.0
  • TFTP server (with the xinetd server) provides access to files in /var/lib/tftpboot on the boot host
  • pxe and pxelinux use tftp to load pxelinux.0, the pxelinux config file (pxelinux.cfg/default or as specified in dhcpd.conf), the linux kernel and the linux initramfs files
  • the linux kernel uses DHCP (again) to configure the network and mount the root file system (as specified in dhcpd.conf)
  • NFS server on the boot host provides access to the root filesystem.

After booting is complete only the NFS server is required for running Linux. After Linux is fully booted, DHCP, TFTP and PXE are not used (until reboot).

Setup the boot host computer (before el7)

install packages

yum install dhcp tftp-server

configure dhcpd

  • create emacs -nw /etc/logrotate.d/dhcp
/var/log/dhcp.log {
    weekly
    notifempty
    missingok
    postrotate
	/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
	/bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true
    endscript
}
  • put this in emacs -nw /etc/rsyslog.conf right after the line "#### RULES ####"
#### RULES ####

  • chmod a+rx /etc/dhcp
  • emacs -nw /etc/dhcp/dhcpd.conf - add contents from the next section
  • emacs -nw /etc/dhcp/dhcpd.conf - customize for this boot host:
    • change "next-server" to the hostname of this host
    • change "host" entries
  • chkconfig dhcpd on
  • service rsyslog restart # to enable dhcp.log
  • service dhcpd restart # watch /var/log/messages for errors, watch /var/log/dhcp.log for dhcp activity
  • try to boot the VME CPU, watch messages in dhcp.log should be similar to those shown in the next section, the VME CPU should get an IP address and stop on "TFTP load" stage

setup tftp

  • emacs -nw /etc/xinetd.d/tftp line "server_args" to read "server_args = -vvvv -s /var/lib/tftpboot"
  • chkconfig tftp on
  • chkconfig xinetd on
  • service xinetd restart
  • try to boot the VME CPU, watch messages in the syslog, should see message about "pxelinux.0 not found", the VME CPU should get an IP address and stop with an error "TFTP - File not found"

setup pxelinux

cd ~

setup linux kernel files

  • get vmlinuz and initramfs files from the VME processor boot image
  • note that the initramfs file needs to be built with the dracut-network function, it should be about 2.5Mbytes in size.
  • note the file names must match the file names in the pxelinux config file
wget http://ladd00.triumf.ca/tftpboot/vmlinuz-2.6.32-431.11.2.el6.i686
wget http://ladd00.triumf.ca/tftpboot/initramfs-2.6.32-431.11.2.el6.i686.img
  • try to boot the VME CPU, watch messages in the syslog, the VME CPU should get an IP address, load the PXELINUX menu, load the linux kernel and stop with an error mounting NFS filesystems.

setup NFS export of VME processor boot image

  • copy the VME processor boot image to /nfsroot/alphavme03 (or /home1/alphavme03)
  • customise the boot image per instructions in previous section (edit sysconfig/network, etc)
  • edit /etc/exports:
/nfsroot/alphavme03 daqtmp4(rw,no_root_squash,async)
  • chkconfig nfs on; service nfs restart
  • if needed adjust the boot image path name in dhcpd.conf to match the export name in /etc/exports, restart dhcpd.conf
  • try to boot the VME CPU, watch messages in the syslog, the VME CPU should get an IP address, load the PXELINUX menu, load the linux kernel, linux kernel will start, mount the VME processor boot image ("NFS Root"), boot the userland. At the end you should be able to ping and ssh into the VME processor.

wget https://www.kernel.org/pub/linux/utils/boot/syslinux/4.xx/syslinux-4.03.tar.bz2
tar xjvf syslinux-4.03.tar.bz2
cd syslinux-4.03
cp -pv ./core/pxelinux.0 ./com32/hdt/hdt.c32 ./memdisk/memdisk ./com32/menu/menu.c32 /var/lib/tftpboot/
  • mkdir /var/lib/tftpboot/pxelinux.cfg
  • create /var/lib/tftpboot/pxelinux.cfg/default with contents from the next section
  • get additional boot files
cd /var/lib/tftpboot
wget http://ladd00.triumf.ca/tftpboot/memtest86+-4.20.iso.zip
wget http://ladd00.triumf.ca/tftpboot/memtest86+-5.01.iso.gz

wget http://ladd00.triumf.ca/tftpboot/modules.pcimap
wget http://ladd00.triumf.ca/tftpboot/pci.ids

setup linux kernel files

  • get vmlinuz and initramfs files from the VME processor boot image
  • note that the initramfs file needs to be built with the dracut-network function, it should be about 2.5Mbytes in size.
  • note the file names must match the file names in the pxelinux config file
wget http://ladd00.triumf.ca/tftpboot/vmlinuz-2.6.32-431.11.2.el6.i686
wget http://ladd00.triumf.ca/tftpboot/initramfs-2.6.32-431.11.2.el6.i686.img
  • try to boot the VME CPU, watch messages in the syslog, the VME CPU should get an IP address, load the PXELINUX menu, load the linux kernel and stop with an error mounting NFS filesystems.

setup NFS export of VME processor boot image

  • copy the VME processor boot image to /nfsroot/alphavme03 (or /home1/alphavme03)
  • customise the boot image per instructions in previous section (edit sysconfig/network, etc)
  • edit /etc/exports:
/nfsroot/alphavme03 daqtmp4(rw,no_root_squash,async)
  • chkconfig nfs on; service nfs restart
  • if needed adjust the boot image path name in dhcpd.conf to match the export name in /etc/exports, restart dhcpd.conf
  • try to boot the VME CPU, watch messages in the syslog, the VME CPU should get an IP address, load the PXELINUX menu, load the linux kernel, linux kernel will start, mount the VME processor boot image ("NFS Root"), boot the userland. At the end you should be able to ping and ssh into the VME processor.
