Hi folks -
I've got a proof of concept environment running on 5.1SP1PR2 on RHEL6. Our backend storage is equalogic arrays via iscsi. I am interested in thin provisioning at the vxvm/vxfs level (similar to multiple volumes of any arbitrary size in the same zfs pool on solaris). Is this possible, or is the only support for thin disks in storage foundation to use a thin lun with the thin reclamation feature (of which our arrays are not compatible with, per the HCL).
In my mind they are two different features - thin provisioning only alloocates space from the on first use. Thin reclamation would return space to the array as blocks are freed by the filesystem. Obviously both together is the desired end state, but even if I can't reclaim space, I'd like to at least not allocate it until it needs to be.
