I have a file server with a NFS server running. /etc/exports
contains this line for the share:
/mnt/datastorev2/data/<username> 192.168.20.*(rw,no_root_squash,no_subtree_check) 192.168.22.*(rw,no_root_squash,no_subtree_check)
On /mnt/datastorev2/
a ZFS mirrored file system is mounted.
I've tried these definitions as below inside /etc/fstab
on my client machine, and am currently using the systemd
one:
192.168.20.72:/mnt/datastorev2/data/<username> /media/<servername>/datastorev2/ nfs rw,noauto,user,_netdev,bg 0 0
192.168.20.72:/mnt/datastorev2/data/<username> /media/<servername>/datastorev2/ nfs noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min,user 0 0
I'm able to mount the file shares using thunar
and dolphin
but after a while the share becomes inaccessible with the message:
mount.nfs: Stale file handle error
And the message in thunar
:
Failed to mount "datastorev2".
Error when getting information for file “/media/< servername >/datastorev2”: Stale file handle.
I'm unable to find real information about this problem and can't find what debug info would be of use (or even where to find these)
I'm using Ubuntu 18.04.2 LTS
with kernel 4.15.0-51-generic
. NFS on both systems is version 4. (Xubuntu is the specific flavour)
(Sidenote: samba isn't an option for me because of latency and because of he fully linux network it would be a shame to use samba.)
update
Executing sudo service nfs-server restart
on the server fixes the problem and the shares become available again after 2 min on the client.
update #2
it seems that it might have something to do with dolhpin
and thunar
being used and installed at the same time. I have installed kubuntu
on the same machine with the same fstab
definitions but haven't had any problems with any stale file handles yet.
