[Linux-cluster] Data Loss / Files and Folders "2-Node_GFS-Cluster"

[Jason Ralph]

Hello List,

We currently have in production a two node cluster with a shared SAS storage
device.  Both nodes are running RHEL5 AP and are connected directly to the
storage device via SAS.  We also have configured a high availability NFS
service directory that is being exported out and is mounted on multiple
other linux servers.

The problem that I am seeing is:
FIle and folders that are using the GFS filesystem and live on the storage
device are mysteriously getting lost.  My first thought was that maybe one
of our many users has deleted them. So I have revoked the users privilleges
and it is still happening.  My other tought was that a rsync script may have
overwrote these files or deleted them.  I have stopped all scripting and
crons and it has happened again.

Can someone help me with a command or a log to view that would show me where
any of these folders may have gone?  Or has anyone else ever run into this
type of data loss using the similar setup?

Regards,
