I ran a scrub on a root pool after upgrading to snv_94, and got checksum
errors:
pool: r00t
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'.

scrub: scrub completed after 0h26m with 1 errors on Thu Jul 17 14:52:14

I ran it again, and it's now reporting the same errors, but still says
"applications are unaffected":
pool: r00t
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'.

scrub: scrub completed after 0h27m with 2 errors on Thu Jul 17 20:24:15 2008

I wonder if I'm running into some combination of:
6725341 Running 'zpool scrub' repeatedly on a pool show an ever
increasing error count
and maybe:
6437568 ditto block repair is incorrectly propagated to root vdev
Any way to dig further to determine what's going on?
