I updated kernels recently and now am getting a corrupt leaf error.
The drives decrypt and mount, and I can touch a file briefly until the
mount switches over to read-only mode. Extended SMART tests show all 6
of my drives have a healthy status. I have a backup of the data. The
array is configured as RAID10. As the BTRFS filesystem remains
accessible / read-only, I am able to take an additional backup. What
is the best way to recover from this error?

Which kernel is reporting the errors?

Btrfs reports at mount time significant number of dropped writes, and
other issues for 2 of 6 drives. This are problems that have already
happened, the statistics are recorded in file system metadata. What's
the history that might explain this? Any power failures or crashes?
When was the last time it was scrubbed?
>[ 130.415056] BTRFS error (device dm-0): block=2533706842112 read time tree block corruption detected
What happens after this line? File ends here.
What do you get for
btrfs check /dev/
This is readonly, and repair isn't recommended unless a dev advises
it. The check only needs to be run on one device.

The VM is reporting the errors. A power failure or crash is likely to
blame. Scrubs happen monthly (3 weeks ago). No other BTRFS messages in
dmesg to report, just a bunch of sudo audit's.

What are the details of the storage stack? What are the Btrfs devices
backed by on the host? Physical partitions, or qcow2, or raw files? If
they are files, is chattr +C set?
And what is the cache method being used for each device?
>A power failure or crash is likely to

The host or the VM? The VM can crash, it's fairly safe, I even use
unsafe cache on all my VMs (it's way faster) and a force power off on
VMs all the time with Btrfs and never have a problem. But, it's a
different story if the host crashes.
It's a little strange that only two devices are affected.

Btrfs check might take a while on 5.7T. It depends on how much
metadata there is.

This is not something caused by a powerloss, but more likely an older
kernel, or memory corruption.
Please provide the following command dump:
# btrfs ins dump-tree -b 2533706842112 /dev/dm-0
Furthermore, btrfs check output would be appreciated to ensure that's
the only corruption.
But from the generation mismatch, it looks like there are transid
mismatch error, which could be a bigger problem than your corrupted csum
tree.
Thanks,
Qu

6x 2tb scsi drives. Raw physical partitions, working through LUKS.
Proxmox passes the devices directly through to the VM without touching
them.

This csum item is too large, overlapping the next item.
Doesn't looks like a bit flip, as the item size still matches.

Since the csum error is the only error, you can fix it by
--init-csum-tree option from btrfs check.

It came up with some kind of `840 abort`. Then I reran btrfs check and
tried again.
$ btrfs check --init-csum-tree /dev/mapper/luks0

This means the metadata space is used up.
Which btrfs-progs version are you using?
Some older btrfs-progs have a bug in space reservation.

It's possible a pacman upgrade triggered this BTRFS event. I don't
know what was previously installed. Here is what is installed now.
$ btrfs version
btrfs-progs v5.4

Then it's a bug in btrfs-progs. I need to find sometime to reproduce the
problem and fix it.
`btrfs fi df` output may help in this case.
For now, I only have possible workaround, that is to delete the
offending files which contains the csum.
You can try the following command to locate the offending files:
# btrfs ins logical 68761178112 -s 45056 <mnt>
And delete related files and hopes kernel find its way to delete the
offending csums.
Thanks,
Qu

A crash is a bug, but at least it didn't make the problem worse. I'm
not sure if 5.4.1 can do any better, but it's the current version.
