Hi,
Sorry, I have managed to fix this now. I noticed in the logline:
Aug 6 13:26:23 ldb03 cibadmin[2140]: notice: crm_log_args: Invoked:
cibadmin -M -c -o status --xml-text <node_state id="ldb03" uname="ldb03"
ha="active" in_ccm="false" crmd="offline" join="member" expected="down" crm-
debug-origin="manual_clear" shutdown="0"/>
the id is ldb03, not the ID of the node, 12303.
I removed using: crm_node -R "ldb03" --force
and rebooted.
Nodes are now in sync.
Thanks,
Jamie.
