Hi Michael,

ZFS is not a cluster file system and I believe that using a cluster file system is a requirement for RAC One Node. If you are running ZFS or Linux, that is definitely not a cluster file system. If you need a cluster file system on Linux, I would go with ACFS or GPFS.

If you need to stick to ASM, you can add raw disk devices to ASM and drop disks that are on XIO drives. ASM will take care of copying data for you. You may want to boost re-balancing power to 11 for that occasion. Alternatively, if you decide that you don't need cluster, you can use rman backup as copy command and then switch db to copy. However, if given a choice, I would keep RAC One Node because it's an excellent fail-over cluster, which can easily be converted into a full RAC, should the need arise.
