Hi, I'm trying to realize a cluster with 2 nodes that manages a volume
group.
Basically I have a san connected to both nodes that exposes 1 lun. So
both nodes have a disk /dev/sdb. From one node I did:
fdisk /dev/sdb <- Create a partition with type = 8e (LVM)
pvcreate /dev/sdb1
vgcreate myvg
then
pcs resource create halvm LVM volgrpname=myvg exclusive=true
Last command fails with an error: "LVM: myvg did not activate correctly"
Reading /usr/lib/ocf/resource.d/heartbeat/LVM, this happens because it
seems that I need at least one logical volume inside the volume group
before create the resource. Is this correct?
Yes, you need to create pv, vg before you use cluster to manager it.
Furthermore, how can I set volume_list in lvm.conf? Actually in
lvm.conf I have:
Normally, clvm is used in cluster with shared storage as:
locking_type = 3
use_lvmetad = 0
locking_type = 1
use_lvmetad = 1
volume_list = [ "vg-with-root-lv" ]
Thank you
