I have two node cluster (SLES10 SP1 + OES2) with master IP resource (all configured without errors). Storage is also SLES10 SP1 with iSCSI target (block device, 20 GB). Nodes are connected via iSCSI initiators and all works fine.

The problem is that when I try to create traditional linux volume for cluster in evmsgui, I can't save changes after deleting a non-CMS segment manager. I get message: "Device or resource busy", and I can't lay down a CMS on my shared volume. Tried to ps aux |grep evms but all looks OK. Tried to reboot all nodes in cluster but a get same error message. Tried to search Novell support but no luck.

What to do?

Thanks in advance!
