Backup problem version1.3

[Petrus4]

I am having issues with both snapshot and stop backups on one openVZ container. All other machines are backing up correctly. Can anyone help me trouble shoot this?

Here are the logs for the "Stop" mode backup


Detailed backup logs:

vzdump --quiet --node 1 --stop --compress --dumpdir /var/lib/vz/backup --mailto user@domain.com 107

These are the logs for "snapshot" mode backup


vzdump --quiet --node 1 --snapshot --compress --dumpdir /var/lib/vz/backup --mailto user@domain --all

I updated the system:

aptitude update
aptitude upgrade

and it seems to have fixed the issue.

Hi,

we are facing the same issue, and also in only 1 vm. We would prefer to find a solution instead of having to upgrade. The system is in production and running very well so we do not want to upgrade just in case.

Any idea about the error stated at the beguining of this Thread?

Thanks

looks like a network problem.

but the backup is done locally, and it happens only to one VM. Even if I stop the vm I get the same problem.

thanks

The the local write fails:

rsync: writefd_unbuffered failed to write 4

Maybe you run out of space on /var/tmp?

The upgrade I did is really a "safe-upgrade" so not a major upgrade. It upgrades any binaries that have been updated in the repositories inclduing the rsync binaries. I belief that fixed my issue. You could also just update the rsync binaries.
