Yes i have 8 nodes but only 4 /dev/drbdX devices, where X={1,2,3,4} are mirroring each two nodes... > GFS need shared storage(SAN) - one raw device which could be visible on > the few nodes. Using iscsi i can export /dev/drbdX which will be visible by all M servers as raw devices as you say. With lvm i can unify all /dev/drbdX in a logical volume and run GFS on top. Why will not work? Is a drbd limitation? Regards, Alx
