Hi David, We are using 4.1 progs and 4.1 kernel on Rockstor currently and what I see is that btrfs check says device is not currently mounted. Is 4.1 effected? Do you recommend we update to 4.1.2 anyway?
[root@RockStor ~]# btrfs fi show testpool; mount | grep testpool; btrfs check /dev/sdaa; btrfs check /dev/sdab Label: 'testpool' uuid: ed600942-f300-4a01-aa49-6b0ab6c0b8f9 Total devices 2 FS bytes used 3.69GiB devid 1 size 2.00GiB used 2.00GiB path /dev/sdaa devid 2 size 2.00GiB used 2.00GiB path /dev/sdab btrfs-progs v4.1 /dev/sdaa on /mnt2/testpool type btrfs (rw,relatime,space_cache) /dev/sdac on /mnt2/testpool2 type btrfs (rw,relatime,space_cache) /dev/sdaa is currently mounted. Aborting. /dev/sdab is currently mounted. Aborting.
