RHBA-2008:0407 - Bug Fix Advisory

Topic

Updated conga packages that fix several bugs and add enhancements are now
available.

Description

The conga packages contain a web-based administration tool for remote
cluster and storage management.

These updated packages fix the following bugs:

• nodes were rebooted when creating a new cluster. As well, nodes were

rebooted when added to an existing cluster. Cluster nodes are no longer
unnecessarily rebooted.

• conga did not set the the "nodename" attribute for manual fencing,

resulting in manual fencing being non-functional.

• there were no time outs, causing Conga to hang with a "Please be patient
• this cluster's configuration is being modified" message. To prevent tasks

blocking all operations on the cluster or host, users are now given the
option to proceed while waiting for tasks to finish.

• the space character was not accepted for fence-device passwords in

"cluster.conf".

• clusters and storage systems were cascaded on the luci "Manage Systems

and Clusters" page, in the "Remove clusters and systems" box.

• when adding systems to an existing cluster, users had to enter the system

password multiple times.

• removing a node from a cluster did not remove the corresponding fence

device.

• if the "trust" box was not selected when adding a cluster to the luci

homebase, errors such as "* You must either trust [system-name] or remove
it." occurred.

• the luci "File System Resource Configuration" page did not reflect the

settings in "cluster.conf".

• the "details" link, which provided no extra information, has been

removed.

• "luci_admin init" asked for a user password, and if luci was running,

"luci_admin init" crashed. Now, the "luci_admin" tool checks if Conga is
running, and if it is, prints a warning, before attempting any operations.

• when Conga restarted the cluster services, cluster service init scripts

were enabled, even if they were disabled.

• the cluster restart operation was not handled correctly, causing nodes

to stop, services to fail, or get stuck in a loop.

• when adding a new instance for a node that uses dual power fencing,

Conga failed to produce the correct fencing configuration.

• conga used the FQDN, instead of the node name in "cluster.conf", causing

"fence_node" to fail if a mismatch occurred.

• probing storage using luci and the Mozilla Firefox 2 Web browser, on

Microsoft Windows XP, appeared to never finish, when in fact it had.

• when configuring an IP address resource, it was not possible to enter a

FQDN. Now, only IP addresses are allowed.

As well, these updated packages add the following enhancements:

• the graphical view is now the default view for partition tables.
• users can now set the "__independent_subtree" attribute for portions of

cluster services, allowing resources and their dependencies to be
restarted, instead of the whole service.

• clearer instructions are now given when accessing Conga, prior to

running "luci_admin init" to initialize the environment.

• the "self_fence" attribute can now be set for clusterfs cluster

resources.

• the Conga web interface now supports Microsoft Internet Explorer, and

Mozilla Firefox, running on Microsoft Windows XP and Microsoft Windows
Vista clients.

• a Sybase failover resource agent has been added.
• users can now configure whether a service will be failed-back or not.
• users can now choose between "live" and "paused" migrations for virtual

machines. The default migration policy is now "live".

• the luci minimum password length has been increased to 6 characters.
• users are now automatically logged out after 10 minutes of inactivity.
• when clustered storage packages are installed, the lvm2-cluster and GFS

packages are also installed.

Users of conga are advised to upgrade to these updated packages, which
resolve these issues and add these enhancements.
