can someone tell me the purpose of directories in /var/lib/nfs location?


hi all

i have been facing some issues with nfs, suddenly sometimes its getting not-responding error from its clients. Both the server and clients are running with RHEL 5.4 on x86_64 platform. I could see the following directories inside /var/lib/nfs
Quote:
etab rmtab rpc_pipefs statd state v4recovery xtab
i know the use etab,rmtab and xtab files. I want to know about the rest. I googled enough to find the details, but i failed. Can someone explain the use of other directories in /var/lib/nfs location?

I got the following errors while i reboot my server.

You appear to have 2 servers

The 2nd quote show that the server/system einbalx0002 is booting and attempting to connect via nfs to another server einbalx0005 .
You need to check the nfs settings on the 2nd server; looks like nfs is disabled there.

no, the second server was working fine at that time. I have gone through the logs, but all i can find was some "negative update cache" errors. Can you explain me about the rest of the logs part?
