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
intended to add later as a mirror) - took 3.5 hrs
* added a new volume
mkfs.btrfs device add /dev/sde1
* started balance and convert to raid 1 - took 8 to 10 hours..overnight
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/datanew
* rebooted next morning
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 (apparently no errors), superblock
seems fine.. tried btrfs rescue commands.. no issues found to fix
* Found several hits on search but not many solutions..except "btrfs filesystem
resize max /" which doesnt work as I'm unable to mount in the first place..
btrfs filesystem resize max /mnt/datanew/
ERROR: not a btrfs filesystem: /mnt/datanew/
Any suggestions? Thanks
