NFS Problems Causes System Crash

Postby illzcx » Thu Apr 21, 2005 3:17 pm

After about 5 days of operation, NFS returns intermittent "No Such File or Directory" errors. The frequency of this occurence escelates until ultimately the server crashes. Upon reboot, it is initially fine until about 5 days later when problem starts up again. This problem is occuring on two separate Dell PowerEdge 1850's with 2GB RAM, running CentOS 4 with software raid 1 over two drives. Any suggestions?

This also happens to our file-server after about 2 weeks operation. I'm now trying to adjusting the rmem_default and rmem_max proc-parameters before starting nfsd and restoring them to default after. A value of about 256K should be fine according to Linux Administration Handbook (Nemeth) ...

Also mounting them tcp option could increase stability.
