Hi all,

I need help. Over night some of my iscsi lvm disk report status unknow. I remove them from cluster storage setup and now i cannot reattach them back to cluster.

Can someone help with this?

I have 4 nodes in cluster connected to hp 3par over iscsi 10gb network.

Best regards

Were there any errors in the log? Did the luns drop off from all nodes? Are you getting errors when you are trying to attach them? What exactly do you mean by "attach"?
What is the context of "/etc/pve/storage.cfg" ? What is the output of:
iscsiadm -m nodes
iscsiadm -m sessions
lsscsi
pvesm scan iscsi [portal]

I apologize, I am unable to follow your description of the issue. If you feel like you cant add sufficient CLI output to demonstrate your issue, perhaps you can use screenshots.
Keep in mind that many technologies use the same terminology for different things, ie "virtual disks".
