So even though the device add command hangs, another shell with btrfs fi show reports that it succeeded: Label: none uuid: d50b6c0f-518a-455f-9740-e29779649250 Total devices 4 FS bytes used 5.70GiB devid 1 size 7.81GiB used 4.02GiB path /dev/sdb devid 2 size 7.81GiB used 3.01GiB path /dev/sdc devid 3 size 7.81GiB used 4.01GiB path devid 4 size 7.81GiB used 0.00 path /dev/sdd Yet umount <mp> says the target is busy. ps reports the command status D+.
