Issues with backup / vzdump

[holgihero]

Hi everybody,

we got a backup job which could not finish (disk full). The perlscript stayed pending (shouldn't we have a timeout here?). Furthermore other sheduled jobs got started cueing up with no chance to ever get processed. In my oppinion there should be a mechanism (semaphore or similar) to prevent backup jobs from starting before older ones get processed.

How can we stop the processes which are left over? We get these remaining artefacts:
173978 ? Ds 57:40 task UPIDrox-main-2:0002A79A:34F5E8FA:549933C2:vzdump::root@pam:
305844 ? D 0:00 /usr/bin/perl -w -T /usr/bin/vzdump 530 --quiet 1 --mode snapshot --mailto sfssdfsf.de --compress lzo --storage Backup-NAS-1
432751 ? D 0:00 /usr/bin/perl -w -T /usr/bin/vzdump 530 --quiet 1 --mode snapshot --mailto ghhhh.de --compress lzo --storage Backup-NAS-1
559594 ? D 0:00 /usr/bin/perl -w -T /usr/bin/vzdump 530 --quiet 1 --mode snapshot --mailto sfhrjjj.de --compress lzo --storage Backup-NAS-1

Cant kill them w kill -9

Any advice?

Thanks and regards, Holger

Very lucky to come across your post. May I ask how you eventually resolved it? I'm currently facing the same issue.

Hi,
if you have a hanging NFS/network mount (verify by going there and issuing an ls command or similar - if it also ends up in uninterruptible D state/your shell hangs, it's very likely that), you can use umount -l -f /path/to/mount/point to tell the kernel to unmount it lazily.

Thank you for your response. I have previously tried following your method, but it did not work.

Was there a hanging network mount in your case? Please check your system log/journal around the time the issue happens. What does the output of ps faxl for the part with the vzdump task?
