6:33 p.m.
I have made a system with one oss, one mds and 2 clients, mdt mgs ost on SAN Netapp.
Separate mgs and mdt on two devices.
4 lustre file system.
Everything was working fine, until my oss crash, i dont know why.
2 file system have come back normally, but the 2 others dont work. I can see the files but
not edit them.
From clients, it tell me that OST is inactive. So i unmount the ost,
unmount mdt, and when i want to remount the mdt, it tells me "transport endpoint not
connected" (the mgs is on the same node with mdt).
So i try to unmount the MGS, remount it, try to remount my MDT, same problem !
Any idea to resolve this problem ?
Thanks.

Hi everyone,
Thanks for your answers.
I plan to install lustre 2.2 because i have clients on rhel 5.5, by seeing the lustre
matrix, it seems i'm stuck on lustre 2.2, or 2.3 if i upgrade my clients to rhel 5.9,
isnt'it ?
Is there any problems with this lustre release ?

I would ask why you are installing Lustre 2.2 at this point? That is an old version of
Lustre for which no maintenance releases was or will be made.
Better to stick with a version like 2.4 or 2.5 which will have maintenance releases with
bug fixes.
Cheers, Andreas
Does i have to use the driver include in RHEL or install mellanox OFED ?
If i'm not wrong, RPM from whamcloud are built against infiniband driver included in
RHEL6.
Is there something specific to install ?
Thanks.
Cheers, Andreas
