Hi,
Hi!
I'm presently setting up an 8 node GFS cluster.
All nodes bar one will mount two GFS files systems from a SAN.
We will used lvm2-cluster on all nodes. All the GFS partitions will use
LVM.
I've defined locking_type = 2 and locking_library =
"liblvm2clusterlock.so" in /etc/lvm/lvm.conf on all nodes.
My question is: Can I mount a VDISK from the SAN as a block device with
an ext3 filesystem on it and mount GFS partitions at the same time?
Given that LVM will be configured on this node with locking_type = 2 and
locking_library = "liblvm2clusterlock.so"
The filesystems will be mounted on unique mount points on the host.
Can I also mount yet another VDISK on the same node this time ext3 on
LVM?
Yes, why not? Just define the volume group you create with that VDISK as non-clustered. All in all, the VDISK should be visible only to "the one" node so the others won't notice there is some lvm stuff there.
I would emphasize that only one node will mount the ext3 filesystems.
I guess this is permissable but I wanted to check.
Many thanks ...
You're welcome,
Juanra
