Hi,



I think the problem is solved. I was using a 9000bytes MTU on the Xen virtual machines' iSCSI interface. Switching back to 1500bytes MTU caused the clvmd to start working.

Double-check that the 2nd node can read and write the shared iSCSI

Reading/writing from/to the iSCSI storage device works as seen below.



On the 1st node:
