RHBA-2009:1444 - Bug Fix Advisory
Synopsis
cman bug-fix update
Type/Severity
Bug Fix Advisory
Topic
Updated cman packages that fix a big are now available.
Description
The Cluster Manager (cman) utility provides user-level services for
managing a Linux cluster.
This update applies the following bug fix:
- in several places internally, cman assumed a transition message meant the
node in question (or the sending node) was joining the cluster rather than
just sending its current post-transition state. In some circumstances this
could lead to cman killing the wrong nodes. With this update, cman now
checks the first_trans flag, which is set when a node first encounters
another node in the cluster. Only if first_trans is set does cman now
consider the node as joining the cluster. (BZ#518060)
All cman users should upgrade to these updated packages, which resolve this
issue.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
