LVM commands causes node panic on Power PC

This document (7017098) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)


HAE cluster setup with dlm/clvm.  After installation LVM commands will cause the server to panic in dlm's _request_lock routine.


We found that specifying the nodeID on the etc/corosync/corosync.conf file prevents the problem from happening, however it is more desirable to have a generic corosync.conf.  Changing the "clear_node_high_bit: new" (by default) to "clear_node_high_bit: yes" in /etc/corosync/corosync.conf does resolve the issue without specifying the nodeID
