Default Bug#584906: nfs-kernel-server: nfs stop working suddenly

Package: nfs-kernel-server
Version: 1:1.1.2-6lenny1
Severity: important

In this server nfs have been working perfectly one year and half. However,
lately we have have some serious issues with the nfs. Simply, the service
stop and the _only_ way to repair the service is restarting the service.

In the logs the only reference that we have is:

orion mountd[4905]: couldn't open /var/lib/nfs/etab

It's a bit annoying because our little network depends on that service.

Regards,

Leo

Do you have any idea why /var/lib/nfs/etab might be deleted or made
unreadable? This file is a working copy of /etc/exports (created by
exportfs) and may be read by mountd at any time, so it must always be
present and readable.

no ... the filesystem is consistent and when it works, works normally. I have
not seen no important messages referring to nfs. Some idea to get information
about this?

If you install inotify-tools you can then use
'inotifywait -m /var/lib/nfs' to monitor changes in this directory. (It
should be possible to get a timestamp for every change, but this feature
seems to be broken.) The other option is to use auditd. This should be
able to give you more detail, but would be more complex to set up.

Hi,

I have had three fails in the last 12 days. Finally I got to set up

at 18:47 the nfs-kernel-server fails in all the clients. Some idea?
