Why happen the error "parent transid verify failed"?

[aug7744]

Hello. Thanks for reading my topic.
Here using Lubuntu 24.04.3 kernel 6.14.
BTRFS partitions are using Rapiddisk writeback cache ( dm-writecache ).
Ramdonly happen the error “parent transid verify failed” if not is done writeback flush. Sometimes is fatal error in file system.
Why happen that error “parent transid verify failed” ? Is related only with BTRFS or other file system too ?
Doing writeback flush avoid it, but has another way to avoid that error ?
Have a nice week.

The error means that underlying storage stack reordered or lost writes from the btrfs driver. You need to investigate where it happens. From your description it sounds like dm-writecache may cause it.
