Hi,
I found one of our servers with a read-only btrfs this morning.
dmesg says:
BTRFS critical (device dm-1): corrupt leaf: block=6404379377664
slot=66 extent bytenr=3138606432256 len=18446619972284938920 invalid
extent length, have 18446619972284938920 expect aligned to 4096
...
BTRFS error (device dm-1): block=6404379377664 write time tree block
corruption detected
(more dmesg log statements in attached file).
The server has ECC RAM with no recorded memory errors in the system
event log, FWIW.

looks like all is well.
After a reboot, btrfsck didn't find any errors any more. Additionally,
btfs-scrub also completed without errors.
Seems like the write time btrfs corruption checks found everything before
committing to disk. Possibly a memory error despite ECC RAM?
To any future readers having similar problems: Do not trust any checks / log
statements before reboot if you encounter possible btrfs corruption.
All the best,
Bernhard
