Thanks Javier for setup ideas.
We are using ServerLoft Dedicated hosting.
So, don't have much control over what can be done from a hardware perspective.
Their servers are good and cheap.
Only problem is that they don't support anything above 500 GBx2 with RAID 1.
We are trying to figure a work-around to use the storage across the servers more efficiently.
Is there a possibility to use LVM2 with some kind of NFS/GFS?
Regards
Rajan

you can run an iSCSI target, NBD server, or vblade on each machine;
then join'em all with cLVM. not for the faint of heart, though, and
redundancy isn't easy either.
DRBD is a slightly different configuration where you definitely get
some failure protection; but it's typically limited to just 2 nodes.
if you need more than that, you end layering both solutions. again,
totally doable; but you have to design the solution yourself.
