Why NFS Drive is dismounting Frequently in Linux

irfanb146 · 07-14-2008, 05:53 AM

Hi,
Could i find the reason of dismounting of drive frequently after 4 or 5 days. Is there any log which can be useful to find out the reason.

I am using mount drive to create archive log file of Oracle 10g on linux on other server.

I am using Linux 64 bit(debian) in both serves.

Regards

NFS can get umounted by network issues, reboot, hung or stale mounts, etc. I've had better experience using AutoFS for NFS mounts. It mounts it when it needs it, then umounts when it doesn't. It'll save you time in having to go remount if it gets hung, etc.

I agree with trickykid - you should use autofs for nfs mounts. It won't use up the extra network traffic. Also, I recommend doing soft mounts as opposed to hard mounts.

Yeah, forgot to mention soft mounts. Much more forgiving if the NFS server goes away temporarily, etc.
