[SOLVED] Vzdump backups were working, now they're not. Help needed.

I'm trying to figure out why vzdump is failing on one of my CT's. It was working fine for a few weeks and now suddenly it just fails after taking almost 2 hours to finish.

Here is the log:

What does the Input/output error mean and is that what's causing it to fail?

TIA

Can you try shutting down your pgsql server before running the backup? I vaguely remember seeing a bug about this on this forum recently.

Will try that and see what happens. Thanks

Just to update this thread.

So it was the disk going bad, everything started to slow down on our Windows guest so went to investigate and found that the disk could no longer reallocate sectors due to the amount of bad sectors on the disk.

Data was still readable so did a few mysqldumps of our databases on the linux CT's (seeing I couldn't get the vzdump backups to complete) and then just restored to a clean disk from the last good backup.

Problem solved
