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!

Bengt
