MowTee Posted June 15, 2021 Share Posted June 15, 2021 (edited) Armbianmonitor: http://ix.io/3q2F Hi all, My Hard Drive in my HC2 is not found or not readable. Before I was on Armbian Buster with Kernel 4.14 and everything was working fine. I switched and am now running Armbian Focal 21.05.2 with Kernel 5.4.116 . HDD is btrfs formatted. /proc/filesystems lists btrfs so this is not the problem. /dev/sda exists, but sda will not be listed when I lsblk. Dmesg shows a Read Capacity(16) failed. Not posting the whole dmesg log b/c armbianmonitor is attached. Grateful for any help or hints =) Edited June 15, 2021 by MowTee 0 Quote Link to comment Share on other sites More sharing options...
Solution Igor Posted June 15, 2021 Solution Share Posted June 15, 2021 2 minutes ago, MowTee said: HDD is btrfs formatted I highly suspect this is something to do with filesystem driver incompatibility between kernel 4.14.y and 5.4.y. We don't support BTRFS even commercially, but you can find commercial support elsewhere https://en.wikipedia.org/wiki/Btrfs#Commercial_support Perhaps there is a way to upgrade somehow ... 7 minutes ago, MowTee said: Grateful for any help or hints =) Plan B will only cost you your time. Starting from 4.14.y, coping elsewhere, starting with 5.4.y ... or staying on 4.14.y. 0 Quote Link to comment Share on other sites More sharing options...
MowTee Posted June 17, 2021 Author Share Posted June 17, 2021 Could not reply right away b/c of new member restrictions. Can confirm Kernel 4.14.y works, also for Focal. Thx for quick and intuitively correct answer 0 Quote Link to comment Share on other sites More sharing options...
