RHBA-2014:1428 - resource-agents bug fix and enhancement update

Synopsis

resource-agents bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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.
