Hi, Recently I'm trying to implement a write-intent bitmap for btrfs to address its write-hole problems for RAID56.
Is there any reason you want a bit-map? Not a journal?The write-hole has been addressed with journaling already, and this will be adding a new and not-needed feature - not saying it wouldn't be nice to have, but do we need another way to skin this cat?
