List-Unsubscribe: , List-Archive: How are you planning on creating this filesystem? I have tried creating 2TB filessystems here for a while and have had little or no luck w/ Solaris or linux. Using Disksuite for solaris and LVM and MD for linux no luck. I have not tried veritas VM yet but even calling up SUN the answer is that 1TB is the limit per filesystem currently under solaris 8 & 9 Linux is really around 980GB or so where it starts to flake out.
