Title:
systemd automount hangs desktop if NFS volume is offline
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am running Ubuntu 16.04. Since upgrading from 14.04 to 16.04, I have
found that the 'auto' fstab mount option no longer mounts NFS volumes
on access. I found that I need to use the x-systemd.automount fstab
option to automount my NFS volumes on access.
However, if the NFS volume is inaccessible, e.g. I am not on a
network, the desktop freezes permanently (no timeout) when I go to the
desktop menu. I think that is because two of the NFS mounts are listed
under "Places". Also, 'df' hangs in such cases. I am using these mount
options:
async,soft,noauto,x-systemd.automount,x-systemd.device-
timeout=10,timeo=14,intr,_netdev
When the permanent hang happens, the only solution is to log into a
character screen and modify /etc/fstab to comment out the NFS entry
and reboot.
Is this expected? Is there a new way to accomplish this?
