Can not read from shared storage

Hi dear members.

We have a strange problem with our shared storage.

We have 2 Bl25p servers with RHEL4u3 connected to EVA 6000 using QLA Multipath driver with two 2/16 SAN switches (four multiple paths).

The two servers use a 150 GB LUN, formatted as OCFS2 that is heavily utilized during the business hours.

Our problem is that sometime the shared LUN is not readable and the processes that need to access the file system ( like ls) on shared storage get uninterpretable sleep (the ps -x shows the process as D+ ).

Any idea? Please Help us.

Re: Can not read from shared storage

Any information in /var/log/messages or dmesg output?

How do you recover from the problem?
