separate subpackages patch to device-mapper.spec
Testing specfile patch based on the changes from the Fedora version of these
packages. Built in brew & hand-tested on PPC.
Note the patch also includes changes to Release: that will need to be modified
before this is committed.

Description of problem: The device-mapper packages shipped in RHEL5 have a problem on multilib ppc systems. device-mapper contains several components: shared & static libraries docs & header files binaries installed in /sbin Both the ppc and ppc64 device-mapper RPMs are shipped in the current RHEL5 releases. The install ordering on PPC installs the 64-bit version after the 32-bit version, overwriting the binaries in /sbin. This causes a problem since the lvm2 package provides a plugin that is used by one of the daemons installed by the device-mapper-package (dmeventd and the libdevmapper-event-lvm2mirror.so plugin). Only the 32-bit lvm2 packages are shipped, so only the 32-bit plugin is installed. This then fails when a mirrored logical volume is created because the event daemon that monitors it is a 64-bit process. Version-Release number of selected component (if applicable): 1.02.13-1.el5 How reproducible: 100% Steps to Reproduce: 1. Install a ppc system from RHEL-5/RHEL-5.1 2. Attempt to create a mirrored logical volume, e.g.: lvcreate -v -n mirror0 -L 100M -m1 tg0 (tg0 can be any volume group with at least two PVs) Actual results: # lvcreate -n mirror0 -L 100M -m1 tg0 tg0-mirror0: event registration failed: Can not access a needed shared library Logical volume "mirror0" created Expected results: # lvcreate -v -n mirror0 -L 100M -m1 tg0 Logical volume "mirror0" created Additional info: This was addressed in Fedora by splitting the device-mapper package up into separate device-mapper, device-mapper-libs, and device-mapper-devel sub-packages. Tested successfully on RHEl5 versions of these packages.
