I am using lxc containers on nfs storage. It was working well, until yesterday I had to restart my NFS server and proxmox won't boot my existing containers. I can create a new container which does boot up, but it won't start existing containers.

I am getting:
Code: 
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 346 To get more details, run the container in foreground mode.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.
TASK ERROR: command 'lxc-start -n 104' failed: exit code 1


I've tried starting them via lxc-start -n 444 -F --logfile=lxc.log --logpriority=debug

It seems my problem is the nfs server itself, my zfs filesystem is faulty which does return generic io error even if I try read the type of container disk, by running `file vm-xxx.raw`. Thanks for help!
