I there really isn't anything different than an auto imported pool.  I'm
suspecting using an alternate cache location my be triggering something
else to go wrong in the nlockmgr.

Here's the command RSF-1 uses to import the pool:
zpool import -c /opt/HAC/RSF-1/etc/volume-cache/nrgpool.cache -o
cachefile=/opt/HAC/RSF-1/etc/v
olume-cache/nrgpool.cache-live -o failmode=panic  nrgpool

After the pool import it  puts the ip addresses back and is done.   That
happens in less than 1 second.

In the mean time NFS services auto start and nlockmgr starts spinning.

I did that this time, no joy.   Today I'm working on a virtual setup with
HA to see if I can get this reproduced on r151012.

I thought this nlockmgr propblem was related to lots of nfs exports until,
I ran into this on my SSD pool.  It used to be able to fail over in about
3-5 seconds.   It takes nlockmgr now sits in a spinning state for a few
minutes and fails every time.   A clear of the maintenance mode, brings it
back nearly instantly.   This is on r151010.  On r151012 it fails every
time.

Hopefully I can reproduce and I'll start a new thread copying Illumos too.
