Fixed In Version: lvm2-2.02.107-1.el6 Doc Type: Bug Fix
Doc Text:
LVM2 and all its subpackages now define strict version dependencies amongst themselves, including a dependency between the lvm2-cluster subpackage and the lvm2 package. This way the lvm2-cluster subpackage always depends on the right lvm2 package.

Description Jesse Triplett 2014-04-03 17:36:07 UTC 
Description of problem:
The lvm2-cluster sub package (and probably others) have a require of >= version but do not work unless they are the exact same version.  RPMs should be configured with sub packages requiring the exact version of the main package not >= because of this issue.

If you install version x of lvm2 and install version x-1 of lvm2-cluster you will see that lvm2-cluster does not work correctly and you can't use lvm2 inside a cluster.

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

How reproducible:
This is what I have from my support tech that has the issue.
1) built a cluster with 2.02.83-3.el6 installed
2) disabled test-svc
3) "yum update lvm2" which updated lvm2 and lvm2-libs
4) "service clvmd restart"

It fails to start because it can't gain an exclusive lock:

 [root@student105 ~]# clusvcadm -e test-svc
 Local machine trying to enable service:test-svc...Failure

 [root@student105 ~]# rpm -qa | grep ^lvm2 | sort
 lvm2-2.02.98-9.el6_4.3.x86_64
 lvm2-cluster-2.02.83-3.el6.x86_64
 lvm2-libs-2.02.98-9.el6_4.3.x86_64

 Mar 11 11:18:38 student105 rgmanager[1338]: #68: Failed to start
service:test-svc; return value: 1

If we upgrade lvm2-cluster and restart clvmd that will fix the problem.
I have left it in the broken state for you.

Note this is an HA-LVM configuration.  This would never happen if the sub package required the same version as the main package.

We'll think about how to deal with this and whether or not we do still need to allow people to combine different versions.  (Normally they are compatible.)
Any fix would apply from RHEL6.6 and RHEL7.1 onwards.

I'd probably go with a firm dependency on exact version. What is the disadvantage? The only one I see at the moment is that clvmd is restarted on package upgrade. But that should be working...

Hard dependencies are being enforced. 
As tested in Bug #1089229 (dependencies with device-mapper).

 You could try using --skip-broken to work around the problem
