Synopsis
pcs bug fix and enhancement update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated pcs packages that fix several bugs and add various enhancements are now
available for Red Hat Enterprise Linux 6.
Description
The pcs packages provide a command-line configuration system for the Pacemaker
and Corosync utilities.
The pcs packages have been upgraded to upstream version 0.9.139, which provides
a number of bug fixes and enhancements over the previous version. (BZ#1185738)
This update also fixes the following bugs:
- After the user added a duplicate resource operation, Pacemaker configuration
became invalid. With this update, pcs does not add the operation and instead
informs the user that the same operation already exists. (BZ#1031141)
- The user could not manage Red Hat Enterprise Linux 6 clusters using the pcsd
web UI running on a Red Hat Enterprise Linux 7 host. The bug has been fixed, and
it is now possible to add or create clusters in this situation. Note that the
pcsd web UI is still not available on Red Hat Enterprise Linux 6 hosts.
(BZ#1160359)
- After the user displayed the list of STONITH devices or resources, their
locations were not included. Now, the list also contains the locations of the
devices and resources. (BZ#1174244)
- The "pcs resource describe" command displayed the resource agent description
on one line, which made it difficult to read. Now, pcs displays the description
as it is defined in the agent. (BZ#1174793)
- After displaying information about a fence agent, pcs showed the description
of the options but not the description of the fence agent itself. Now, the fence
agent description is displayed as well in this situation. (BZ#1174798)
- Previously, pcs stopped cluster nodes sequentially one at a time, which caused
the cluster resources to be moved from one node to another pointlessly.
Consequently, the stop operation took a long time to finish. Also, losing the
quorum during the process could result in node fencing. With this update, pcs
stops the nodes simultaneously, preventing the resources from being moved around
pointlessly and speeding up the stop operation. In addition, pcs prints a
warning if stopping the nodes would cause the cluster to lose the quorum. To
stop the nodes in this situation, the user is required to add the "--force"
option. (BZ#1174801, BZ#1184763)
- The "pcs status --full" command did not output the node attributes and
migration summary. Similarly, the "pcs config" command did not display the
resource and operation defaults. Both commands have been modified to display
this information. (BZ#1184922, BZ#1187488)
- After the user attempted to ban or clear a clone resource, pcs displayed an
error message stating the resource did not exist. With this update, pcs supports
banning and clearing clone resources. The "pcs resource ban" command creates a
constraint on a cloned resource, and the "pcs resource clear" command removes
that constraint. (BZ#1190167)
- When using the User Datagram Protocol unicast (UDPU) transport, the cluster is
required to be restarted in order for the node to be added or removed properly.
Previously, pcs did not inform the user about this requirement. Now, pcs warns
the user to restart the cluster. (BZ#1191898)
- After the user removed a node from a cluster, the cluster could fence the
removed node. This update modifies pcs to reload the cluster.conf file after
adding or removing a node, thus fixing the bug. (BZ#1193433)
In addition, this update adds the following enhancement:
- This update adds support for configuring the Redundant Ring Protocol (RRP) and
setting Corosync options. The user can now configure a cluster with RRP and set
up corosync options. (BZ#1121769)
- The clufter package is now installed as a pcs dependency. With clufter
installed, pcs is able to import CMAN configuration from the cluster.conf file
and convert it into Pacemaker configuration. (BZ#1171312)
Users of pcs are advised to upgrade to these updated packages, which fix these
bugs and add these enhancements.
Solution
Before applying this update, make sure all previously released errata relevant
to your system have been applied.
