The we can use that to proof expanding our capabilities re user configurable data/metadata raid levels down the road. And our next move in this area would be to surface within the Web-UI what data and metadata are actually stored in first. Again, all in good time and we are not quite there just yet. This should help to enable the parity raids feasability a little as then one can use say Raid1c3 for metadata and raid6 for data.

Plus we hope in time to support the capability to pick both data and metadata raid levels independantly. There is some work going on in that direction but most work seems to be on the 1/10 and there will soon be the btrfs Raid1c2 and Raid1c3 variants that may be interesting. The same command can erase filesystem, raid or partition-table signatures/metadata. uuidparse vipw (including symlink to vigr) wall wdctl whereis wipefs.

wipefs does not erase the filesystem itself nor any other data from the device. wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid. But we will have to see how things pan out for the parity raids. util-linux is a standard package distributed by the Linux Kernel Organization for use as. The wipefs program lets you easily delete the partition-table signature: wipefs -a /dev/sda From man wipefs. But it’s often easier to fix something that exists than to start over. It’s a little like 2 file systems in one really as the parity raids don’t fully conform to the main remits of btrfs so should probably not have been added. And yes the raid1/10 within btrfs is far more mature, and faster, than the parity raids of 5/6. You can issue this command on a running system. There is kernel work on-going to improve this type of drive management and that should, in time, make such operations as you did make more sense rather than throwing these resource busy errors.Īll in good time and thanks for reporting your findings. It’s OK when removing a single drive from a pool via resize but when dropping an entire pool a reboot is often required. Btrfs can often fail to ‘drop’ a drive from the ‘busy’ list even when the pool has been deleted. I rebooted RockStor … and … I was able to wipe the drives.
