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.
