[Linux-cluster] bug in cman-kernel / membership.c

[Lazar Obradovic]

Just got this when joining one node.


CMAN: Waiting to join or form a Linux-cluster
CMAN: sending membership request
CMAN: got node new-noc
Got ENDTRANS from a node not the master: master: 6, sender: 1
CMAN: node new-noc is not responding - removing from the cluster
