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
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.
