February 9, 20242 yr How do I remount a non-array pool? I have a non-array pool (btrfs), external hard drive, and accidentally turned the power off to one of the drives in the pool. I turned the power back on, but the pool doesn't appear to be mounted. Notice the drive is "MISSING": # btrfs filesystem show Label: none uuid: bcaa0df3-5b21-44f1-9293-f5f0ecee8ef6 Total devices 1 FS bytes used 5.28TiB devid 1 size 5.46TiB used 5.40TiB path /dev/md2p1 Label: none uuid: 03ba8866-a578-4d09-bddf-aa64ed48afe6 Total devices 2 FS bytes used 1.63TiB devid 1 size 931.51GiB used 919.51GiB path /dev/sdj1 devid 3 size 931.51GiB used 904.51GiB path /dev/sdk1 Label: none uuid: b687a212-2cbf-48f8-9b97-ccc49e39d661 Total devices 2 FS bytes used 347.89GiB devid 1 size 238.47GiB used 238.47GiB path /dev/sdi1 devid 2 size 0 used 0 path /dev/sdb1 MISSING
