/me is so happy that the Indiana project surfaced.

I have found ZFS to be very much stable on OpenSolaris stable releases 
and have not had any issues on OpenIndiana 147 with 9 1TB disks in a 
raidz2 pool. There are reports of those who had problems when upgrading 
but I however have not - whether difference in env/procedure was 
responsible I do not know but those chaps got help on the Openindiana ml 
with their zfs problems.

I have used OpenSolaris since 2008.05 stable release without issues. 
Long term support/updates is not an absolute certainty at the moment 
with regards to OpenIndiana but that is only in the terms of packages 
outside the core image since illumos is guaranteed.
