Lustre discuss - Sep 2010 - Lustre module not getting loaded in MDS

Hello All,

I have installed and configured Lustre 1.8.4 on SuSe 11.0 and everything
works fine if i run modprobe lustre and when the lustre module is getting
loaded. But when the server reboots it is not getting loaded. Kindly help.

Lnet is configured in /etc/modprobe.conf.local as below.

options lnet networks=tcp0(eth0) accept=all

For loading lustre module i tried including lustre module in the variable
MODULES_LOADED_ON_BOOT using yast2 sysconfig . But still it is not getting
loaded.

Error from dmesg is as below.

LustreError: 1393:0:(socklnd.c:2543:ksocknal_enumerate_interfaces())
Can''t
enumerate interfaces: 0
LustreError: 105-4: Error -100 starting up LNI tcp
LustreError: 1393:0:(events.c:725:ptlrpc_init_portals()) network
initialisation failed
Currently this is present in the VM.

Kindly suggest.

Regards,
Prasad

Hi Prasad,
I''m not a SuSe user but I think it''s because your system is
trying to
load lustre modules before NIC is up.
" Can''t enumerate interfaces: 0" means socklnd found ZERO
interface.

Liang

We''ve had problems with suse in the past. These were avoided by
creating
/etc/rc.d/after.local containing:

modprobe lustre
mount -a

not pretty, but effective.
