[OpenIndiana-discuss] how to stop a zfs resilver

[John McEntee]

I have a production system so I should have tried this at the weekend but is it a 3 way mirror across 7 vdevs (is that the right term), see below.

I started of the resilver yesterday, but it is have too much of a performance penalty on of the of VMWARE windows machines. I tried to reduce the priority with

echo zfs_resilver_delay/w8 | mdb -kw
echo zfs_resilver_min_time_ms/W0t100|mdb -kw

but that did not have a big enough affect.  Next  I tried to stop the resilver so I could run it over the weekend it by running offline but the resilver is still happening. Any idea how I stop it?

Thanks

John
