Hi there, just a question about how the bitmap stuff works with
1++-redundancy, say RAID1 with 2 mirrors, or RAID6.
One disk fails and is replaced/reattached, and resync begins. Now
another disk fails and is replaced. Is the bitmap local to each disk?
And in case of RAID1, with 4 disks (and two of them resyncing), could
disk3 be rebuild from disk1 and disk4 from disk2 (as to optimize disk
bandwidth)?
