[Lustre-discuss] Newbie w/issues

[Brian Andrus]

Ok, I inherited a lustre filesystem used on a cluster.

I am seeing an issue where on the frontend, I see all of /work
On nodes, however, I only see SOME of the user's directories.

Work consists of one MDT/MGS and 3 osts
The osts are LVMs served from a DDN via infiniband

Running the kernel modules/client one the nodes/frontend
lustre-client-1.8.2-2.6.18_164.11.1.el5_lustre.1.8.2
lustre-client-modules-1.8.2-2.6.18_164.11.1.el5_lustre.1.8.2

on the ost/mdt
lustre-modules-1.8.2-2.6.18_164.11.1.el5_lustre.1.8.2
kernel-2.6.18-164.11.1.el5_lustre.1.8.2
lustre-1.8.2-2.6.18_164.11.1.el5_lustre.1.8.2
lustre-ldiskfs-3.0.9-2.6.18_164.11.1.el5_lustre.1.8.2

I have so many error messages in the logs, I am not sure which to sift
through for this issue.
A quick tail on the MDT:

Any direction/insigt would be most helpful.
