It scrubbed up good

Since the home server has been snapping regularly I have had to choose between snapshots and scrubbing and I chose snapshots. User error is more likely than hardware failures and scrubbing is really about seeing those errors sooner so you don't get a unrecoverable failure due to having two problems at once. However I would rather not have to choose.
So I was particularly pleased to see that build 94 contains the fix for this bug:
6343667 scrub/resilver has to start over when a snapshot is taken
So today the home server had it´s first scrub in years and it scrubbed up well:
: pearson FSS 5 $; pfexec zpool status pool: tank state: ONLINE status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions. scrub: scrub completed after 12h42m with 0 errors on Thu Aug 28 20:12:36 2008 config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror ONLINE 0 0 0 c1d0s7 ONLINE 0 0 0 c5d0s7 ONLINE 0 0 0 errors: No known data errors : pearson FSS 6 $;
When I upgrade the pool, after the other live upgrade boot environment can support this pool version, there is the promise of a faster scrub but since this scrub happened during the day and I also backed up the pool using zfs_backup during the same time.
