Hi,

while playing around with ZFS and USB memory sticks or USB harddisks,
rmvolmgr tends to get in the way, which results in a

  can't open "/dev/rdsk/cNt0d0p0", device busy

error.

So far, I've just said svcadm disable -t rmvolmgr, did my thing, then
said svcadm enable rmvolmgr.

Is there a more elegant approach that tells rmvolmgr to leave certain
devices alone on a per disk basis?

For instance, I'm now running several USB disks with ZFS pools on them, and
even after restarting rmvolmgr or rebooting, ZFS, the disks and rmvolmgr
get along with each other just fine.

What and how does ZFS tell rmvolmgr that a particular set of disks belongs
to ZFS and should not be treated as removable?

Best regards,
   Constantin
