That's a great suggestion. And as fortune would have it, we have the

Aye, or better yet -- give the scrub/resilver/snap reset issue fix very
high priority. As it stands snapshots are impossible when you need to
resilver and scrub (even on supposedly sun supported thumper configs).
No argument. One of our top engineers is working on this as we speak.

We have a 18TB big zpool, it takes more then 2 days to do the scrub.
Since we cannot take snapshots during the scrub, this is unacceptable

We have recently discovered the same issue on one of our internal build
machines. We have a daily bringover of the Teamware onnv-gate that is
snapshoted when it completes and as such we can never run a full scrub.
Given some of our storage is reaching (or past) EOSL I really want to

just scrubbing the pool-wide metadata, then scrubbing each filesystem.

A brief search didn't show anything relevant, so here
goes:
Would it be feasible to support a scrub per-filesystem
rather than per-pool?
The reason is that on a large system, a scrub of a pool can
take excessively long (and, indeed, may never complete).
Running a scrub on each filesystem allows
