We use Solaris and I have to say ZFS is quite amazing.  Never have to 
run fsck ever again!

The checksum feature ensures that when you read the data back, it's what 
was written out.
If you have mirroring like we do, it can then get the data from the 
other side.  Once a month
I run a zpool scrub on the 1.1 TB mail-pool just to be sure, it runs 
overnight while the system
is live, there is no need for downtime.

This is a compelling reason for us to stay with Solaris on the 
mail-store systems.
