Pacemaker lvm cluster

Question

I have added disks to the cluster nodes through the "iscsid target" server. Those disks are visible with "lsblk". ( /dev/sdb) . But when you want to create "vg" and "lv" on the disks, it is not possible.

enter image description here

What form should this process take on 'node' - 1 if "vg" and "lv" are created, should I do this on the second "node"?

Answer 1

You need first to "prepare" this disk for LVM:

pvcreate /dev/sdb

and then add to VG

vgcreate clustervg /dev/sdb
