Hi!
I can't mount my RAID1 set as rootfs, but as normal mount to running
system works normally. It was working normal, than some day it died.
When booted to rootfs as
root=UUID=98c94774-d93a-400e-a275-58cc3ac2a58a rootflags=subvol=@root
i got:
BTRFS error (device bcache2): devid 5 uuid
dd09f810-717e-4f2f-97ab-26469d5adca5 is missing
BTRFS error (device bcache2): failed to read the system array: -2
BTRFS error (device bcache2): open_ctree failed
mount: mounting /dev/bcache2 on /root failed: Invalid argument
Having the '-o degraded' mount option will make this successful but
looks like the other disk is slow to be identified as you were able to
mount after boot.
Thanks, Anand
and (initramfs) prompt.
Bcache devices are registered and populated in /dev.
When I boot exacly the same kernel and initrd, but rootfs is on
pendrive ( root=/dev/sda2 ) than mount dataset to subdir ( mount UUID=
98c94774-d93a-400e-a275-58cc3ac2a58a /data ) - works flawlessly.
Thanks in advance for any ideas.
