Hi Ari, A cluster requires a minimum of one volume per head. So having a 6 disk vol0 and a spare per node is fine. Make sure that you follow the directions in the cluster configuration guide carefully to avoid any situation where both nodes are cabled incorrectly allowing access to the same volume at the same time. In fact, I thought NetApp always did the initial cluster configuration. Is that option available to you? -Steve

Hi,
I am setting up a pair of clustered 740's for the first time and have a question.
Each filer currently has one disk shelf. 6 of the disks are in the root volume, /vol/vol0, and the 7th is a hot spare. Is this configuration OK for a clustered pair? I was told by someone that for a cluster, I would need 2 distinct volumes on each head, although I am not entirely sure why. If that is the case, how do I remove drives from the root volume so that I can add them into a newly created volume?
Any help is greatly appreciated.

Now I am confused. If there is only one volume, then what you have is essentially a "hot spare filer" for failover. Surely setting up two volumes lets you use both filers actively and gets you more bang for the buck? While a single volume cluster might work, is it really the recommended config?
