Bug Fix Advisory

Topic

Updated cman packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The Cluster Manager (cman) utility provides user-level services for managing a
Linux cluster.

This update fixes the following bugs:

• Prior to this update, ccs_tool could fail due to a segmentation fault in two
  specific events. First, the input file was the same as the output file and
  options were specified with a subcommand. Second, the update command was used
  without an input file. With this update, ccs_tool has been fixed to report the
  appropriate error message without a segmentation fault. (BZ#714042)
  
• Previously, fence_xvm, a fencing agent commonly used in virtual deployments,
  did not respect the delay parameter as specified in the cluster.conf file. With
  this update, the delay support has been added and the fence_xvm agent now works
  only after the specified delay. (BZ#854183)
  
• Under some circumstances, cman returned the file descriptor for the /dev/zero
  file, which is always active. If the client application stored this /dev/zero
  file instead of the one it expected, cman entered an infinite loop. This update
  addresses the bug by making sure that the fence daemon refreshes the file
  descriptor on each operation. (BZ#856214)
  
• In a two node cluster where the network was not always reliable, and a token
  was lost but recovered before fencing was complete, the two nodes simultaneously
  killed each other. To fix this bug, only one node has been allowed to kill the
  other in a deterministic fashion. A cluster restart, one node at a time, is
  required for this change to take effect. (BZ#876731)
  
• Prior to this update, fenced, the daemon in charge of evicting cluster nodes,
  could suffer from a time-out while communicating with the ccsd cluster
  configuration daemon. The fenced daemon has been reconnected to ccsd when
  certain operations take too long to complete, thus fixing this bug. (BZ#881217)
  
• Previously, man pages had executable flags set. The manual pages permissions
  have been edited to agree with FHS standard, thus fixing this bug. (BZ#883816)
  
• Prior to this update, the end-of-line automatic character detection worked
  properly only when using ssh on certain Dell DRAC devices. With this update, the
  end-of-line character detection has been fixed and fencing works as expected.
  (BZ#904195)
  
• Prior to this update, APC power switches with firmware version 5.x were not
  supported. Consequently, the fence_apc fencing script could not login to the
  device. With this update, new firmware is supported and the fencing script is
  able to log in. (BZ#886612)
  
• Previously, the fence agent for Intel IPMILAN standard did not return exit
  code correctly when using the 'cycle' method. A patch has been provided to fix
  this bug and exit codes are now returned as expected. (BZ#961119)
  
• Prior to this update, the cman(5) man page did not document how to enable
  detailed logging in the CMAN subsystem. This update documents this facility in
  more detail. (BZ#963251)
  

Users of cman are advised to upgrade to these updated packages, which fix these
bugs.
