5.283. ricci

Previously, the ccs utility was not able to configure IPV6 hosts. The ccs utility has been updated to support the IPV6 protocol, so that it can be used to configure IPV6 hosts.

The cman and ccs utilities contain different cluster schemas for Red Hat Enterprise Linux 6.2. A different cluster schema on a node from the schema contained in ccs could cause a valid cluster.conf file to be interpreted as invalid by ccs. A new ccs option, "--getschema", has been added. Using this option, if cluster schemas are different between what is included in ccs and the information on a node, the cluster schema on the node is used.

Previously, the ccs utility did not check to see if the cluster.conf file was invalid. Therefore, when parsing an invalid cluster.conf file, ccs could terminate unexpectedly followed by a traceback, however with no detailed information about the problem provided. With this update, ccs checks to see whether cluster.conf is valid; if the file is invalid, ccs prints a helpful error message and exits gracefully.

Previously, the "ccs_sync" command did not return a non-zero exit code if an error occurred or the ricci daemon was not running, even when running the command with the "-w" option (to exit with a failure status if any warnings were issued). The underlying source code has been modified so that "ccs_sync" with the "-w" option now returns "1" on failure.

When running the "ccs" command with the "--checkconf" and "-f" options, ccs verifies that all the nodes in the file specified contain the same cluster.conf file. The XML code in the configuration file is indented whereas the XML code in the live configuration file from ricci is not, and therefore bare comparison of such strings always failed. As a consequence, ccs did not verify each node in the local cluster.conf file. The comparison method has been improved so that "ccs --checkconf -f" now correctly verifies whether all the nodes in the file contain the same cluster.conf file.

Previously, if the user installed the ricci packages but did not install the modcluster package, any attempt to run cluster commands using ricci failed. With this update, users are no longer allowed to install only the ricci packages; the modcluster package is now required as a dependency. As a result, cluster commands can be executed as expected.

Previously, when the user configured a virtual machine service, the virtual machine was not displayed in the output of the "ccs --lsservices" command. The ccs utility has been modified to specifically check for virtual machine services in the configuration file. Now, running "ccs" with the "--lsservices" option prints the proper output.

Previously, if the user installed ricci and did not set a user password, the user was unable to connect to ricci. This could lead to confusion, because the user was not prompted to provide the password and therefore not aware of the requirement. Also, no explanation was logged in the system log. With this update, ricci logs a warning message to syslog on startup if the ricci user password is not set.

Prior to this update, the ricci daemon processed tasks, but did not log any information about when the tasks were run. With this update, when ricci is asked to spawn a worker process, the date and time information is now logged using syslog.

Prior to this update, the ccs utility did not provide a way to configure Redundant Ring Protocol (RRP). This update adds additional configuration options for RRP into the ccs utility so that users can configure RRP using ccs.
