[Bug 1931790] [NEW] Unable to mount btrfs RAID 1 filesystem after reboot

Sun Jun 13 06:02:44 UTC 2021

Public bug reported:

Hi,

I'm unable to mount my newly created btrfs RAID 1 filesystem after
reboot..I performed the below steps with my 2 X 1 TB drives:

* created a new btrfs filesystem
mkfs.btrfs /dev/sdd1

* mounted it to /mnt/datanew
mount -t btrfs /dev/sdd1 /mnt/datanew

* copied over data from my previous NTFS volume on /dev/sde1 (which I
intend to add later )

* added a new volume
mkfs.btrfs device add /dev/sde1

* started balance and convert to raid 1
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/datanew

* rebooted

I seeing below errors:
[  792.045980] BTRFS info (device sdd1): allowing degraded mounts
[  792.045988] BTRFS info (device sdd1): disk space caching is enabled
[  792.045990] BTRFS info (device sdd1): has skinny extents
[  792.047498] BTRFS error (device sdd1): device total_bytes should be at most 1000201841152 but found 1000203804672
[  792.049207] BTRFS error (device sdd1): failed to read chunk tree: -22
[  792.051525] BTRFS error (device sdd1): open_ctree failed
* Manual mount has below error additonally
mount: /mnt/datanew: wrong fs type, bad option, bad superblock on /dev/sde1, missing codepage or helper program, or other error.

* Verified the data seems intact, superblock seems fine.. tried btrfs
rescue commands.. no issues found

* Found several hits on search but not many solutions..except "btrfs filesystem resize max /" which doesnt work..
btrfs filesystem resize max /mnt/datanew/
ERROR: not a btrfs filesystem: /mnt/datanew/

Any suggestions? Thanks
