A client accidentally removed important files that had changed significantly after the last snapshot and backup.
A disk was pulled out of the mirror asap, and part of the data could be accessed by rolling back to the oldest uberblock available, but it was too late for some of the files.
Are there tools to find missing files past the last few txg or does it sound reasonable that I scan the disk for a bit older objset_phys_t metadnode to find a MOS and try to manually make an uberblock that points to it?
Anybody want to have a go building a tool? I understood that the data is worth something. :)
- the pool wasn't full and not much has happened since the data was removed
- compression=yes
- older version of the data is referenced by a snapshot
