Description Marek Grac 2011-07-01 12:01:05 UTC 
+++ This bug was initially created as a clone of Bug #698002 +++

Description of problem:

The cman RPM does not depend on pyOpenSSL, and fence_ilo simply fails with "Unable to connect/login to fencing device", regardless if '-v' or '-D /tmp/foo' are passed. This makes it very difficult to sort out what is wrong.

It is true that the fence_ilo man page indicates that this is a required package, but it is easily missed when people skip the DESCRIPTION section and go right to reading the switches.

Version-Release number of selected component (if applicable):

cman-2.0.115-68.el5.x86_64
fence_ilo: FENCE_RELEASE_NAME="2.0.115";

How reproducible:

100%

Steps to Reproduce:
1. Uninstall pyOpenSSL
2. Run 'fence_ilo -a <ip> -l <user> -p <pass> -o reboot
3.
  
Actual results:

Fails with a generic error message

Expected results:

Report that a dependent package is missing.

cman should be dependent on pyOpenSSL. Today I run into huge problems after cluster split brain condition with this error.

You created an identical Bug #718208 against RHEL 5.6. Did you test against both distribution versions?
Comment 6 Radek Steiger 2011-10-18 10:52:51 UTC 
Marking as VERIFIED for fence-agents-3.1.5-10.el6

Since the only change is the rpm package dependency list, tested simply by calling:

[root@z1 tmp]# rpm -e pyOpenSSL
error: Failed dependencies:
	pyOpenSSL is needed by (installed) rhnlib-2.5.22-12.el6.noarch
	pyOpenSSL is needed by (installed) fence-agents-3.1.5-10.el6.i686
	pyOpenSSL is needed by (installed) python-paste-1.7.4-1.el6.noarch
	pyOpenSSL is needed by (installed) python-paste-script-1.7.3-4.el6.noarch


The rpm error clearly shows that pyOpenSSL cannot be removed without removing fence-agents as well, therefore solves the original issue.
