Backup freeze after nfs server shutdown

[eliotte]

Hi,

I have a strang probleme. I try to stop a backup and it failed. In my log I see:

kernel: ct0 nfs: server 10.222.217.166 not responding, still trying

If I type ps aux | grep vzdump, I find the PID but if try, as root, kill PID# it doesn't work.

The result is: all the GUI is not responsive. I do not want to reboot, must be a way! All my CT and VM are running.

I'm running 3.2.

Ps: we have 2 separate node with subscription (basic one)!

I am afraid reboot might be the solution to this problem. Had this problem with NFS shares. If i recall right i never found the solution for it. Did you try to migrate all VM using command line then try to reboot?
# qm migrate <vm_id> <dest_node>

Hi,

I did a reboot... but each time I reboot, I need to do it manually, I mean physically. The reboot command never work. Anyway, everything is fine after the "reboot"

About your question, No I didn't try that. Next time!

did you try to issue
#umount -f -l <nfs share>?

I'm not sure it should work, just could, as it happened to solve other nfs issues (stale file handle lock)

I tried but without the -f option

On my dev machine, I will try to get the same state and test it with -f option.

I tried but without the -f option.

ok, be sure to use both options together, -f and -l
