I'm not sure which of my btrfs FS has the issue yet since BUG_ON isn't very helpful as discussed earlier. [160562.925463] parent transid verify failed on 2776298520576 wanted 41015 found 18120 [160562.950297] ------------[ cut here ]------------ [160562.965904] kernel BUG at fs/btrfs/locking.c:269! But shouldn't messages like 'parent transid verify failed' print which device this happened on to give the operator a hint on where the problem is? Could someone do a pass at those and make sure they all print the device ID/name? Bug below: Full log before the crash: INFO: task btrfs-transacti:3358 blocked for more than 120 seconds.
