Hi Qu,
Tried it with backup roots and it won't mount. I have a backup of a
week ago and I'll accept the dataloss.
I'll rebuild (this time without BTRFS RAID5/6) and restore.
Thanks for your help!

Hi Qu,
I know about RAID5/6 risks, so I won't blame anyone but myself. I'm
currenlty working on another solution, but I was not quite there yet...

BTRFS restore shows the following output:

If you search the list for 'corrupt leaf bad key ordering' the top two
causes are bad RAM and flaky power supply. These can be hard to narrow
down. But yes pretty good chance it can be fixed with 'btrfs check
--repair' but two things before you do that:
a. Make sure backups are up to date. Hopeful

Hi,
I decided I wanted to try if letting btrfs manipulate those extens would
have fixed my issue. So I launched a full balance followed by a
deduplication followed by another full balance. Then I checked the fs once
again: everything got fixed during the data manipulation.
Anyway btrfs check --

the data. Below I have the output of some of the requested command. I have

Hi, I've been using btrfs for a while now, I've been utilizing snapshotting
nightly/weekly/monthly. During the weekly I also do a backup of the
filesystem to an ext4 filesystem. My storage is a linux md raid 5 volume.
I've recently noticed these errors in the logs during the backup of the

Here are some of the errors I have collected in my F13 virt machine
using brtfs. If there is anything else you need just ask and I will
send along.
