Hi. I have electrecity problem, for short period of time it was lost and my computer rebooted.
After that on ST4000DM0004 disk every thing was good except partitions at raid:
$ sudo btrfs filesystem show

mounting this file system does not work:
https://unix.stackexchange.com/q/664950/129967
$ sudo mount -o degraded /dev/sdc3 /mnt/btrfs/
mount: /mnt/btrfs: wrong fs type, bad option, bad superblock on /dev/sdc3, missing codepage or helper program, or other error.
but I can mount it in ro mode:
but can not reattach disk =(
$ sudo mount -o degraded,ro /dev/sdc3 /mnt/btrfs/
$ sudo btrfs replace start -f -B 2 /dev/sdd3 /mnt/btrfs

this is:

Not sure if the specific model is involved, but there are some known
models not really following FLUSH/FUA spec to properly writeback data.

There aren't much info so far for your problem.

Then the dmesg is the critical piece of information.
It maybe a corrupted extent tree, but hard to say just from the inform here.

The latest btrfs-progs would warn you, so does the man page.
You may have already screwed up the last chance of recovery.
