[Linux-cluster] Sane configuration?



Hey all,

Just getting started with the whole GFS/CLVM thing, and wanted to run a config by the people who actually know what they are doing before I try to deploy it, in case I'm doing anything really stupid. :)

I'm basically looking at setting up a 4-node cluster, using GFS to share storage. I've picked up a Dell PowerVault 660F fibre array for the central sotrage, and a PV51F fibre switch (equivilent to a Brocade 2400, apparently), which will have the array and each of the boxes connected to it.

Here's the kicker: I'd like to run Xen on these boxes, and be able to migrate VM's and such between them. (This is really why I want the shared storage, besides just for experience.)

My plan is to create a LUN for each of the individual nodes to boot from, and then have a large shared LUN for CLVM. Within the CLVM PV, I'll create a LV for each of the Xen domains/vm's to boot from, and then have a large GFS LV for the shared data.

Does this sound reasonable? Anyone see any huge holes in my logic? I'm hoping that GFS will compile and work within the Xen-ified Linux kernel - I suppose I should've tried that out before ordering hardware, but ah well. :)

Hope someone has some comments, and thanks for reading!
