Glad to hear it - I'm doing the same thing.  I got the okay from Symantec in 
that there were no know issues with ZFS so I went for it.

I did a clean install of NBU 5.1 MP6 on Solaris 10 on a Sun fire v440. Catalog 
is on a RAID-Z array.

I bought the v440 used and I discovered I have one of the early motherboard 
revs (soon to be replaced) that feature system lockups under certain 
conditions...  Long story short, I had to power-cycle the system and the nice 
thing was the ZFS file system came right up - no more slogging through fsck.

Greetings,

This response is quite delayed, but:  We've been using ZFS to hold the
NBU catalogs (and binaries, and logs) since our initial install of NBU
6.0-MP4 starting last November.  We're running Solaris-10U3 on SPARC
(master server is a T2000).

Regards,

Marion
