"scrub: resilver completed after 5h50m with 0 errors on Tue Jun 23 05:04:18
2009"
Zero errors even though other parts of the message definitely show errors?
This is described here: http://docs.sun.com/app/docs/doc/819-5461/gbcve?a=view
Device errors do not guarantee pool errors when redundancy is present.
Change suggestion to the ZFS programmers:
insert the phrases 'unrecoverable pool data' or 'pool data' or word 'data' into
the error message like this:
"scrub: resilver completed after 5h50m with 0 unrecoverable pool data errors on Tue
Jun 23 05:04:18 2009"
"scrub: resilver completed after 5h50m with 0 pool data errors on Tue Jun 23
05:04:18 2009"
"scrub: resilver completed after 5h50m with 0 data errors on Tue Jun 23 05:04:18
2009"
That would clarify why the status message above it doesn't agree (shows device errors)
nor do the numbers in the config table below it (shows detailed device errors)(3+11+23),
and it would match with the last line that says "No known data errors".

To be honest, never. It's a cheap server sat at home, and I never got around
to writing a script to scrub it and report errors.
I'm going to write one now though! Look at how the resilver finished:
# zpool status
pool: zfspool
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
