I have a five-disk non-redundant zpool where two disks have media
errors. One with five sectors unreadable and the other with three
sectors.
I would like to recover as much data as possible from these disks. What
are my possible options? (And, no, there is no backup.)
Making block-copy clones of the faulty disks and removing files that had
the media errors?
Copying the files that can be read from the pool to a different pool on
other disks?
Other recommendations? Any help appreciated!
