Raid0 rescue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I know I am screwed but hope someone here can point at a possible solution.

I had a pair of btrfs drives in a raid0 configuration.  One of the
drives was pulled by mistake, put in a windows box, and a quick NTFS
format was done.  Then much screaming occurred.

I know the data is still there.  Is there anyway to rebuild the raid
bringing in the bad disk?  I know some info is still good, for example
metadata0 is corrupt but 1 and 2 are good.
The trees look bad which is probably the killer.

I can't run a normal recovery as only half of each file is there.

$100 reward if you come up with a workable solution.
