Ok I booted into a node via rescue mode from a Red Hat 7.2 installation
CD. I noticed that there are certain files missing.
There is no
/etc/lilo.conf
/boot/map
And no ramdisk
Where does OSCAR keep these files? They are also not in the
/var/lib/systemimager/images/oscarimage/ tree on the master node.
This seems odd because I get the LIL- error message and that seems to me
that it is loading a lilo.conf file but I cannot find that file anywhere
on the nodes.

|Chris,
|The change to the switch is irrelevent. Until LILO
|bootstraps the kernel your network card isn't a factor
|- so unless your diskless or using PXE to boot over
|the network, this is an install problem on the local disks.
|
|Check out this link:
|http://user.fundy.net/cyclist/linux/troubleshoot-LILO.html
|
|Here is an excerpt that will point us in the right direction:
| () No part of LILO has been loaded. LILO either
|isn't installed
| or the partition on which its boot sector is
|located isn't active.
| L ... The first stage boot loader has been
|loaded and started,
| but it can't load the second stage boot loader.
|The two-digit error
| codes indicate the type of problem. (See also
|section "Disk error
| codes".) This condition usually indicates a media
|failure or a geometry
| mismatch (e.g. bad disk parameters, see section
|"Disk geometry").
| LI The first stage boot loader was able to load
|the second stage boot
| loader, but has failed to execute it. This can
|either be caused by a
| geometry mismatch or by moving /boot/boot.b
|without running the map
| installer.
| LIL The second stage boot loader has been
|started, but it can't load
| the descriptor table from the map file. This is
|typically caused by a
| media failure or by a geometry mismatch.
| LIL? The second stage boot loader has been loaded
|at an incorrect
| address. This is typically caused by a subtle
|geometry mismatch or by
| moving /boot/boot.b without running the map installer.
| LIL- The descriptor table is corrupt. This can
|either be caused by a
| geometry mismatch or by moving /boot/map without
|running the map
| installer.
| LILO All parts of LILO have been successfully loaded.
|
|Let us know what you find - perhaps the installer is
|having trouble with the map installer.
|
|Keep smiling,
|Greg

| Subject: [Oscar-users] OSCAR cluster dead after
|simple changes
|
| We are currently working on a nasty problem
|with our OSCAR cluster.
|
| I am running OSCAR 2.1 on RedHat 7.2 with a
|modified kernel to
| accommodate for my e1000 gigabit cards and
|mylex hardware RAID.
|
| First the problem.
| We recently received some new nodes for our
|Beowulf cluster. We
| brought the cluster down to install them. We
|installed an additional
| network card to the switch, and manually moved
|the position of the
| old nodes in the rack. When we rebooted up the
|cluster (master and
| old nodes), ALL of the old nodes do not boot
|up. They stop at a
| screen that says
|
|
| LIL-
|
| I have removed the additional card from the
|switch and tried rebooting
| everything. No Joy
| I am able to ping the master node from the
|switch and vice-versa.
|
| If you could give some ideas of where to look?
|Or do I need to
| completely reinstall? I'd rather avoid the
|reinstall because I do not
| know what cause the crash, and thus would be
|susceptible to a
| reoccurrence.
