Why do you say that?

Note of caution. FWIW It is not recommended to mount OCFS2 volumes

One could instead of using a iSCSI adapter, use a common etherned
adapter and mount the iSCSI target using a software driver. The
main CPU would have the additional load of disassembling the TCP/IP
packets and routing them.
Btw, I never actually used one of these boards.

Typically I find folks use 'NAS" to refer to
filesystem level sharing (NFS, Samba), and SAN for block
level (FC, iSCSI).
There are plenty of iSCSI HBAs (I've only used the ones
from qlogic), however they don't 'simulate'
anything - They're just a SCSI adapter with an iSCSI
backend.

If your NAS can do iSCSI you could use it to provide
a shared block device.
The performance wont be as good as a SAN as the data
has to go through the kernel TCP/IP stack, it can be
comparable if you have a iSCSI IP accelerator board that
simulates a hba.

OCFS2 requires a block device (local disk, direct
attached,
SAN), so it's not going to work with a NAS
(Samba, NFS, etc)
mount. You can, of course, share a OCFS2
filesystem using Samba or NFS.

Hi,
Does OCFS require NAS hardware to run or does
normal
PC hard disk work?
Thanks,
