Dear Team,

in the pbs gui I can see a number of bad chunks. I could not find any documentation what bad chunks are to understand the situation and how to get rid of these bad chunks.
Is this just leftover of old stuff and will be deleted some time, or is this a major problem somewhere?

Many thanks,
Andreas
 
a 'bad' chunk is a chunk that does not match its checksum, thus bad data
run a verification on your datastore, the backups which are affected will be marked as failed for verification
 
Hi,
have the same thing here, too now.
Even after complete reverification and GC i get "Leftover bad chunks: 6" in one datastore.
Any idea, what i should do?
thanks

Maybe your backup process crashed(system restart, network problem)? This is what is usually problem in our PBSses
 
can give all-clear.
It seems that not all snapshots were checked during the first verification, but only a few...Can't say exactly why.
But I have now checked all snapshots again and no longer have any bad chunks.
thanks for your help
Sascha
