I use zfs in a san. I have two Sun V440s running solaris 10 U2, which
have luns assigned to them from my Sun SE 3511. So far, it has worked
flawlessly.

Just to make sure there's no confusion ;-), this error message was added to
'ls' after Solaris 10, and hasn't been backported yet. (Bug 4985395, *ls* does

Ed, thanks for the great work on Samba/ZFS! I will be testing the shadow copy
