i have a two_node cluster RHEL 5 and an external ISCSI storage. I use XEN for virtualizzation purpose. When i create a new LUN in my storage i use hot_add command to discover it from nodes.
The problem is that i have to restart clvmd to be able to create a new Logical Volume. This operation is very critical because i have to stop or migrate each VM running on the node ed i have to umout their own LUN.
Is there a way to update clvmd without restarting?
Thanks a lot,
