--- Comment #1 from peter@wemm.org ---
There has been a lot of confusion about this message.  What we know:

1) The command can detect corruption, but

2) the command has internal limits to avoid excessive memory consumption.=20
These limits probably seemed reasonable at the time but they are easily rea=
ched
by a lot of people on perfectly healthy pools. Presumably the limits need t=
o be
adjusted.

3) The #2 false positive is scaring the heck out of people for no good reas=
on.

If you read the github bug https://github.com/openzfs/zfs/issues/15030 you'=
ll
see that people have been recovering pools.  On linux they set
zil_replay_disable (via procfs) to mount the damaged pool and then and
zfs_recover (via procfs) and run a scrub.  We have equivalent sysctls.  YMM=
V of
course.
