Personally, I'd firstly move from ext2 to ext3 to try and prevent this
from happening again.
Then, I would delete all the directorties (in fact, all non-files) from
under the pool/cpool that don't belong.
Then, set the VerifyProb=1 and run a full backup of each host.
Of course, part of me is saying "start fresh"... In fact, I don't think
anyone can really suggest the correct course of action, but the lowest
risk (if you don't need to restore any old data) is to start fresh. All
other options carry some risk, and to be honest, I don't understand
those risks, and probably you don't either (which is why you are asking).
If you have the available space, then start fresh, otherwise, you need
to start to consider the value of your data, and what happens if your
backup is storing corrupt data. What happens if you delete all existing
backups, and then take a set of full backups? How important is the
ability to restore data from last week compared to your space
requirements? Is now a good time to replace your data disks with bigger
disks?
Hope that somewhat helps..... and I also sympathise with you. Best of
luck :)

Adam
