Hi,
i run two HHD's(sda;sdb) in RAID1.
Kernel: 4.9
Distro: Linux odroid 4.9.277-83 #1 SMP PREEMPT Mon Feb 28 15:16:26 UTC
2022 aarch64 aarch64 aarch64 GNU/Linux
btrfs-progs: 5.4.1
I created the filesystem with:
mkfs.btrfs -d raid1 -m raid1 -L somelable -f /dev/sda /dev/sdb
And added it to my fstab:
UUID=<uuid> /mnt/somefolder btrfs compress=zstd 0 2
When running:
mount -a
i get an error:
mount: /mnt/backup: wrong fs type, bad option, bad superblock on
/dev/sda, missing codepage or helper program, or other error.
and dmesg reports:
BTRFS error (device sdb): open_ctree failed
Yours sincerely
Lucas

This in itself is a generic error which doesn't give reasons or details.
dmesg should have reported more than that, could you post all messages that
happened right after after the "mount" command?

Hi Lucas,
Invalid mount options can be reported as "BTRFS error (device sdb): open_ctree
failed". The reason for the error is that your kernel version doesn't support
zstd. 4.14 kernel added support for zstd or 5.1 if you want to set zstd
compression levels by mount option.

I got pointed to this report. First I suspected that there are some
lines missing from the dmesg log, like what was the error but it turns
out that almost all invalid option values lack any message, which makes
the error analysis hard. Thanks for your report, I've sent a patch that
adds the missing messages, there's a lot of them.

This is the problem the only thing in dmesg after mount -a is:
[ 7592.168838] BTRFS error (device sdb): open_ctree failed
