RHBA-2014:1428 - Bug Fix Advisory

주제

Updated resource-agents packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

설명

The resource-agents packages contain a set of scripts to interface with several
services to operate in a High Availability (HA) environment for both the
Pacemaker and rgmanager service managers.

The resource-agents packages have been upgraded to upstream version 3.9.5, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#993431)

This update also fixes the following bugs:

• Previously, the IPaddr2 agent did not send out unsolicited neighbor

advertisements to announce a link-layer address change. Consequently, floating
IPv6 addresses, which require this functionality, could not work correctly. To
fix this bug, the "send_ua" internal binary required for IPaddr2 agent to drive
IPv6 addresses has been added. As a result, the floating IPv6 addresses now work
correctly. Nevertheless, IPv4 addresses are left unaffected by this change.
(BZ#1025909)

• Previously, when an oracledb.sh resource was created without the

"listener_name" option, the rgmanager oracledb resource agent failed to start.
With this update, the oracledb.sh file has been modified to operate correctly
when no "listener_name" is given, and thus oracledb now starts correctly.
(BZ#1025504)

• Prior to this update, the netfs agent could become unresponsive during a stop

operation, even with the "self_fence" option enabled. With this update, the self
fence operation is executed sooner in the process, which ensures that NFS client
detects server leaving if umount can not succeed, and self fencing occurs.
(BZ#1024065)

• Previously, the virtual machine (VM) instances managed by the VirtualDomain

agent failed during the monitor operation if the libvirtd daemon was not
available. This caused the Pacemaker resource manager to unnecessarily recover
healthy VM resources when libvirtd failed. With this update, the VirtualDomain
agent is capable of monitoring KVM virtual machines without requiring libvirtd
to be accessible. As a result, Pacemaker no longer mismanages VM resources in
case of a libvirtd failure. (BZ#1054327)

• Previously, the "no_unmount" functionality was missing in the netfs.sh file.

Consequently, the netfs resource agent did not allow an NFS share to remain
mounted after a service was relocated. This update adds back the missing
functionality, and the file system is now left mounted when the service
relocates. (BZ#993329)

• The following agents were shipped in error, and thus have now been dropped:

nginx, rsyslog, mysql-proxy, and slapd. (BZ#1022793)

• Previously, the SAPInstance resource agent for Pacemaker did not behave

correctly on nodes where the corosync node name did not match the host name. The
check provided by the sapinstance_notify() function has been modified to fix
this bug. The SAPInstance agent now works correctly regardless of the match
between the corosync node name and host name. (BZ#1023340)

• Previously, Pacemaker's nfsserver resource agent was unable to properly

perform NFSv3 network status monitor (NSM) state notifications. As a
consequence, NFSv3 clients could not reclaim file locks after server relocation
or recovery. This update introduces the nfsnotify resource agent, thanks to
which NSM notifications can be sent correctly, thus allowing NFSv3 clients to
reclaim file locks. (BZ#1091101)

Users of resource-agents are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements.
