This is my first post on this list. Thanks in advance for every answer.
The truth is that I've not clear a point about CLVM.
Let's me make an example:
In this example CLVM and the Cluster suite are fully running without problems. Let's pose the same configuration of cluster.conf and lvm.conf and the nodes of the cluster are joined and operatives.
Let's pose that CLVM spans LVM metadata across the cluster, if I stroke the command:
I should see /dev/sda2 and /dev/sda3
and then I can create a vg with
vgcreate /dev/sda2 /dev/sda3 ...
The question is: How LVM metadata sharing works? I have to use GNBD on the row partion to share a device between nodes? I can create a GFS over a spanned volume group? Are shareable only logical volumes?
Thanks for your answers!!
