The raid-stripe-tree is exciting for multiple reasons.
For one, it finally solves the raid56 write-hole similar to how zfs does, by never updating the stripe in-place.
And it is developed by Western Digital for use in zoned storage (host managed SMR), so there is a commercial user of btrfs raid now. This was missing before and was the reason btrfs raid didn't go anywhere for so long.
- Tajnymag 3y agoI thought Synology has used BTRFS on their higher end NAS devices.
- nolist_policy 3y agoYes but they don't contribute upstream. They run a old kernel with an enormous out of tree patchset on top to combine dm-raid with btrfs.
