[Lustre-discuss] Lustre 1.8.7 client on Ubuntu 10.04 LTS

[Donald J. Kolva]

Craig,

Thanks for the reply.

We have the matching kernel 2.6.32-34-server  with the 1.8.7 debs from Wham Cloud which were installed with dpkg -I (client install).

After a reboot, modprobe lnet gives FATAL:module lnet not found

Next step is to try different kernel versions.

Don

Hi Don,

The modules will not load themselves merely because they are installed. 
  Like any Linux kernel module, something will have to try to load them. 
  You don't say so, but I am assuming the kernel you are running matches the kernel version for which the modules were compiled.

If the modules you installed from Whamcloud are really for the kernel you are running, I am suspicious that you may have deployed the Lustre
(client?) modules with dpkg, but have not done anything that tries to actually use them (like trying to mount a Lustre file system).

What do you get if you type "modprobe lnet"?  Does it succeed (check dmesg)?  If there aren't any complaints, try "lctl network up".  And if that succeeds, try "lctl list_nids".

Cheers,
Craig

We have downloaded the .deb files from Whamcloud, installed them with dpkg, then rebooted (expecting to have the modules loaded). The modules didn't seem to load, so we ran modular-assistant, which throws the "/usr/share/modass/overrides/lustre-source: 1: debian/rules: Permission  │ denied" error.  We are sure that all the /debian/rules in the lustre source tree are u+x.
