Question about unsupported volume resizing
This something wholly unsupported but we're playing around with it anyway for experimental reason. If anyone has a thoughts I would love to hear it.
We have a lab / sand box system using commodity storage. Specifically it's a FreeNAS server. We are using it as an iSCSI target and have setup a series of zvols as device extents. On the client side we have Mac pro's, we use one physical port for the iSCSI network, the other port is virutalized with a connection to our public network and metadata network. We are using globalsan client side to connect to the iSCSI storage. We labeled the LUNs, XSAN let us use them to create a SAN.
So my question, one of the things were playing with is resizing volumes and adjusting storage on the fly (or at least with a restart). So lets say I re-size my zvols on my iSCSI side (which I did) which should create a larger volume on the XSAN side, but it doesn't. The volume stays the same size. So how would I tell XSAN that my LUNs (and subsequently my volume) should be larger?
Yes, this is like crossing the streams with our proton packs. It's just a fun thought experiment about using low cost hardware to take advantage of FCPX's SAN Location benefits in low cost labs.
