Hi!
We se sporadical corruption in snapshots (not really files, it seems) since we
started using encryption on previously well behaved system.
$ sudo zpool status -v tank

status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.

entire pool from backup.

errors: Permanent errors have been detected in the following files:
No files though, and the last percent of scrub has been working for a few days
now.
We know which snapshot is problematic since we ship them all off site using
`zfs send`. Removing snapshot culprit fixes the problem, but it keeps popping
up. We're planning upgrade to 14.1 this weekend, but I see no closed PRs about
this problem so I'm posting this before the upgrade. Anyone knows if anything
in the encryption code has been improved?
There a description in the OpenZFS github,
https://github.com/openzfs/zfs/issues/12014 , that seems to be spot on. The
issue is still open.
Any ideaa? What more can I supply in terms of data?
