I don't understand what that means - how can you have two failed drives, but hardware is ok?
If you lost 2 drives out of a 3+1 RAID5, then you have essentially lost your filesystem,
I'm sorry.

because the drives are part of a raid set, and they are not xfs filesystems
on their own.

You can't.

If you lost 2 of your 4 drives, there's not much support to do, I'm afraid.
