OpenZFS Device Removal
- db48x 12y agoThis is good; perfect for that time you fat-finger it and end up adding drives as top-level vdevs instead of adding them as a mirror pair.
- wtallis 12y agoGood to see that progress is being made toward catching up with btrfs in this really useful area. For those of us who don't buy hard drives by the dozen, it's really nice to have absolute flexibility about adding and removing drives and changing RAID modes non-destructively with btrfs, but ZFS still has some pretty enticing features, too.

- GauntletWizard 12y agoNice, this is a feature that'll really improve ZFS's usability for me, as a home user. I'd like to be able to redo my Zpool with a different architecture (6xDisks in RaidZ2 rather than 4x in RaidZ1). Doing it online rather than as a copy would be awesome. The next best thing would be online ZVol restructuring, though.
- PhantomGremlin 12y agoI don't think this will do what you want. One limitation is: Currently, device removal only works if all top level vdevs are plain disks / files. At the very least, we want to make device removal interact intelligently with mirrored disks. I think that statement means that this feature will not work with mirrored or RaidZ* configurations.
