Hi, After updating to kernel 5.2 (archlinux): 2 out of my 7 btrfs drives fail to mount on boot.
Error: can't read superblock on /dev/sdb1 and /dev/sdc1. Going back to kernel 5.1.16 (and 4.19 also) fixes the problem. Btrfsck reports the 2 drives are OK. What can I do to fix this ? Thanks. $ btrfs fi show Label: 'disk3' uuid: 37d68257-a2bf-44e4-82e6-7bda35d3af3c Total devices 1 FS bytes used 1.77TiB devid 1 size 1.82TiB used 1.82TiB path /dev/sdb1 Label: 'disk4' uuid: 8b72d7bd-603c-41c0-a395-a763ffe0de8b Total devices 1 FS bytes used 2.67TiB devid 1 size 2.73TiB used 2.73TiB path /dev/sdc1 Label: 'disk5' uuid: 1728d60b-bdf2-4baa-8372-de7014d85e1d Total devices 1 FS bytes used 3.59TiB devid 1 size 3.64TiB used 3.64TiB path /dev/sdg1 Label: 'disk7' uuid: 5e9437b5-bf53-4135-8b25-52539cfc491e Total devices 1 FS bytes used 6.66TiB devid 1 size 7.28TiB used 7.23TiB path /dev/sde1 Label: 'disk6' uuid: ce325155-0922-4c62-9f5d-70cbc1726b5c Total devices 1 FS bytes used 3.47TiB devid 1 size 3.64TiB used 3.63TiB path /dev/sdd1 Label: 'disk1' uuid: b9c65214-b1dc-4a97-b798-dc9639177880 Total devices 1 FS bytes used 3.31TiB devid 1 size 3.64TiB used 3.62TiB path /dev/sdh1 Label: 'disk2' uuid: d77e4116-de32-4ff4-938c-9c6eea6cdd42 Total devices 1 FS bytes used 6.83TiB devid 1 size 7.28TiB used 7.26TiB path /dev/sdf1
