[Ocfs2-users] Newbie questions

[Ionel GARDAIS]

Hi list,

I'm about to give a try to ocfs2 as clustered storage for a mini-cluster.
For storage, we own 4 XRaids of 10.5TB each viewed as 8 disks of 3.5TB 
(RAID 5 - spare disk).
For computation, we have 4 Dell PE1950 with a FC card running a x86_64 
SMP RHEL4.6 linux.
Storage and compute nodes are interconnected through a QL SanBox 5200.

My plan is to use LVM2 (the classic, not the clusterd one) to present 
one stripped logical device to the nodes.
Do I must use LVM to create this stripping or is OCFS2 able to 
distribute writes over the disks ?
FAQ says that the maximum size of OCFS2 filesystem is 16TB for 32b 
systems. Will I be able to break the limits with a 64b system and use 
the whole 28TB in one partition ?

Thanks for the tips,
Ionel
