Description Shane Bradley 2010-11-23 17:41:33 UTC 
Description of problem:

If the ports for cman are changed from the defaults then ccs_tool will fail to work since the ports for ccs_tool are hardcoded.

For example setting the port values for cman components in /etc/sysconfig/cman:
$ cat /etc/sysconfig/cman
CCSD_OPTS="-P f:40006 -P b:40008 -P c:40009"

Using non-default ports will make ccs_tool fail.

Version-Release number of selected component (if applicable):
cman-2.0.115-34.el5.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1) Tried changing the port on my single node cluster.
$ cat /etc/sysconfig/cman
CCSD_OPTS="-P f:40006 -P b:40008 -P c:40009"

2) Start the service
$ service cman start

See the only node in cluster
$ cman_tool nodes
Node  Sts   Inc   Joined               Name
   1   M     24   2010-09-29 14:39:19  rh5node0.examplerh.com

Get process network port list
$ netstat -tulpn | grep ccsd
tcp        0      0 0.0.0.0:40009 0.0.0.0:*   LISTEN      9427/ccsd
tcp        0      0 ::1:40006     :::*        LISTEN      9427/ccsd
udp        0      0 :::40008      :::*                    9427/ccsd

3) Tested updating cluster.conf version which would contact the ccsd
process. 
$ emacs /etc/cluster/cluster.conf : Inc version by 1.
$ ccs_tool update /etc/cluster/cluster.conf
Unable to open connection to rh5node0.examplerh.com: Bad file descriptor
  
Actual results:
ccs_tool will fail to work since ports are hardcoded.

Expected results:
ccs_tool should either have options for ports or read in /etc/sysconfig/cman options.

Fix

Notes:

1) This patch does not update ccs_tool's "editconf" capabilities, since these are deprecated anyway.

2) You must specify things on the command line; parsing a sysconfig file is not appropriate - /etc/sysconfig files are for init scripts.  The only port you need to change is the 'c' port.  I used ccsd's argument parsing for consistency.

   ccs_tool update -P c:40009 /etc/cluster/cluster.conf

3) This patch is not needed in RHEL6 or STABLE31.
