Subject: [HELP] open_ctree failed when mounting RAID1
Date: Tue, 31 May 2022 21:50:52 +0200	[thread overview]
Message-ID: <9c3fec36-fc61-3a33-4977-a7e207c3fa4e@gmx.de> (raw)

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
