1. I haven't started scrub
Well, a resilver actually. This can be kicked off automatically.
Did you just import this pool?
2. I can't stop it
By design. See the man page:
Because scrubbing and resilvering are I/O-intensive
operations, ZFS only allows one at a time. If a scrub is
already in progress, the "zpool scrub" command ter-
minates it and starts a new scrub. If a resilver is in
progress, ZFS does not allow a scrub to be started until
the resilver completes.
