Dear List,
I'm trying to set up a Lustre 1.6b5 cluster where every nodes except
frontend serve OST, frontend serve MGS+MDT, and every nodes (including
frontend) mount and use Lustre. Somehow there's a weird problem where
some nodes can't mount lustre but some nodes can.
My configuration:
OS: Rocks 4.2.1 Cluster (CentOS 4.4) using stock lustre
2.6.9-42.EL_lustre.1.5.95smp kernel. Frontend has 2 IP (real + private)
and ever compute nodes using private IP.
Lustre: 1.6b5.
Here's log from frontend (MGS+MDT) and the failed client node
Failed client node:
Lustre: mount data:

I think I strictly follow the guide at
https://mail.clusterfs.com/wikis/lustre/MountConf. I suppose that the
problem occurred because IP confusion on Frontend. But some compute
nodes successfully mount lustre file system frontend.
