Subject: [Cluster-devel] [PATCH] DLM: Telnet to port 21064 can stop all lockspaces
Date: Wed, 27 Jun 2007 11:36:23 +0100 [thread overview]
Message-ID: <46823DA7.4030206@redhat.com> (raw)
This patch fixes Red Hat bz#245892
Opening a tcp connection from a cluster member to another cluster member
targeting the dlm port it is enough to stop every dlm operation in the cluster.
This means that GFS and rgmanager will hang.
