Hi,
so, furthering the saga of setting up my first Linux cluster, I
have a need for a quorum disk (its a two-node cluster). So far, I have
been using my "raw" (i.e., no partition table) SAN disks as physical
volumes for LVM. Now, however, I need a 10MB partition for the shared
quorum disk. The remainder of that LUN is a 2nd partition to be used for
LVM.
My question is, what is the best practice in Linux? Do most folks create
a partition table for each LUN, even when used as a physical volume for
LVM. It seems weird to me that I would have:
/dev/mpath/disk0p2
/dev/mpath/disk1
/dev/mpath/disk2
/dev/mpath/disk3
/dev/mpath/disk4
as PVs - seems it would be more consistent to create them all as:
/dev/mpath/disk0p1
/dev/mpath/disk1p1
/dev/mpath/disk2p1
/dev/mpath/disk3p1
/dev/mpath/disk4p1
I'm used to LVM in HP-UX (what the original Sistina LVM was based on),
where we always use whole (aka, non-partitioned) disks...
Thanks for any input.
Kevin
