/dev/sdd is newly created by mkfs, fill with data

this happen on --convert-to-block-group-tree too. an empty hdd however wron't trigger this issue

after the failure, try to convert back

had to reset the mark manually

# echo -ne "\x00" | dd of=/dev/sdd bs=1 seek=60 count=1 conv=notrunc
# btrfs rescue super-recover -v /dev/sdd
ERROR: superblock checksum mismatch: wanted 0xdc5d907c found 0xe705a13d
....
Make sure this is a btrfs disk otherwise the tool will destroy other fs, Are you sure? [y/N]: ^C

# echo -ne "\xe7\x05\xa1\x3d" | dd of=/dev/sdd bs=1 seek=00 count=4 conv=notrunc

however writing more data to the disk cause disk full error, rsync says "No space left on device"

[41068.637379] BTRFS error (device sdd): cow_file_range failed, root=256 inode=53649 start=22708224 len=688128 cur_offset=22708224 cur_alloc_size=0: -28

and a balance is auto-started

# btrfs balance status d-backup
Balance on 'd-backup' is running
0 out of about 74 chunks balanced (0 considered), 100% left

reformat using mkfs.btrfs -O block-group-tree /dev/sdd -f, fill the disk from other disk. at some point, trigger cow_file_range failed too
