Updated lvm2-cluster packages that fix one bug is now available for Red Hat Enterprise Linux 5.
The lvm2-cluster package provides support for Logical Volume Management (LVM) in a clustered environment.
If a physical volume (PV) presented in a volume group (VG) contained only metadata and no physical extents (PE), an attempt to write the volume group's metadata by running the "vgcfgrestore" command was not successful. Running the command failed with the "Floating point exception" error message, which was caused by a "division by zero" error. This bug has been fixed and lvm2-cluster now works correctly in such a case.
All users of lvm2-cluster are advised to upgrade to these updated packages, which fix this bug.
