I created an NSS pool and volume under NW 6 SP5 - I added folders and
files to the volume.

When I re-booted the server a few weeks later, I could not mount the NSS
volume - the traditional volumes came up OK.

When trying to activate the POOL, I get the following error message.

"Could not change pool "DATA_POOL" to Active State"
"Status=20833 zfspool.c [1680]

I've looked at teh TIDs and they seem to relate to Clustering - this
server is not clustered.

The message also seems to indicate that the pool is 'shared' ??
