Details

clients don't remount NFS shares with usable permissions after server reboot or restart of the daemon. the problem lies the exportfs -ua command which doesn't allow reconnection, gives "stale file" error, etc.

reworked nfsd initscript by shazeal fixes the problem (nfsd.mod -- attached).

Attached is the diff of the old/new nfsd script.

Adding the exportfs -ua command alone did not fix the problem. The second issue was that the 2.6 kernels use proc to store/read the xtab information and the xtab in /var/lib/nfs was not being used on startup.

The reload part is used to clear connections while the nfsd is already running. Used more for testing while I was figuring this out but I guess it could be useful.

I've picked this up as I'm currently preparing the nfs-utils 1.1.0 package.

Fix confirmed: this works for me too.

is there an update for this? with the new nfs-utils, shares aren't remounted either on client or server reboot. thanks.

I've just finished some init script changes to handle this with the current nfs-utils and util-linux-ng releases. Remounts after both client and server reboots are working as intended. I will upload the new package shortly.

I picked this up in June, so apologies for the delay.
