Can't kill backup process

[ejmerkel]

I have a standalone Proxmox 4 host which has a hung backup process. I have tried killing the processes from the GUI with no luck and I have also tried killing it from the command line with kill -9 PID but they will not go away.

52700 root D ? 00:00:38 task UPID:fre-he-hv01:0000CDDC:16393A69A:5AAE54C2:vzdump::root@pam:
68988 root D ? 00:10:18 lzop

Is there any other way to stop processes without a reboot of the entire server?

Best regards,
Eric

I guess your backup storage (NFS?) is blocking?

 

[ejmerkel]

Yes, there must have been a glitch in the NFS connection or something. Other servers are working fine backing up to the same NFS server. I tried forced unmounting the NFS mount to see if that would cause the process to close but that didn't help either.

If I just remove /var/run/vzdump.lock and /var/run/vzdump.pid will I be able to run backups again without any issue? I plan on backing up the VM's and moving them to another server so I just need to get backups running again.

I suggest to reboot if those NFS mounts still hang.

The NFS seems to be working ok touch when I just move files back and forth. So would it be ok to just remove the lock and pid files and try another backup?

No, because it seems the existing NFS connections hangs, so there are running processes still using those stale handles, and you cannot kill them.

okey. this is a workround this

for example:
umount -f /mnt/pve/<NAME OF MOUNT> and then kill it in consol by kill -9 or in gui. takes 1min but easy to fix.
