I have this occasionally due to the backup system I am using: - stop the nfs export - umount the filesystem - take LVM snapshot - remound filesystem - re-enable the nfs export When that happens, I run the following on the server: # exportfs -au && sleep 1 && mount -a && sleep 1 && exportfs -r The sleeps are necessary, without them, it doesn't always work. -- Joost
