June 21, 20224 yr I have a 3 disk btrfs cache with raid1, I'd like to remove one disk from the cache, can I simple use btrfs device delete 3 /mnt/cache or I need to stop the array, remove one disk from the cache pool and start the array again?
June 21, 20224 yr You can use the command above but then would need to reset the pool with Unraid before next array start, best to use the the other option.
