An updated system-config-lvm package that fixes multiple bugs is now available for Red Hat Enterprise Linux 6.
The system-config-lvm package contains a utility for configuring logical volumes using a graphical user interface.
The system-config-lvm utility incorrectly displayed all LVM devices in the "Unitialized Entities" group. This could confuse users who could try to re-initialize logical volumes unnecessarily. This update modifies system-config-lvm to show LVM devices as "Unitialized Entities" only if the logical volumes really are uninitialized.
The system-config-lvm utility uses fdisk as a back end for partition operations. The fdisk utility does not support the Extensible Firmware Interface (EFI) GUID Partition Table (GPT), so an attempt to initialize a physical partition on EFI GPT fails. However, system-config-lvm previously did not handle this situation correctly and the operation failed without any error message. This update modifies the underlying code so that system-config-lvm now provides a valid error message in this situation.
The system-config-lvm utility did not properly handle physical partitions with names in the form of "*p[0-9]", for example, "loop0p0". Therefore, system-config-lvm terminated unexpectedly when attempting to initialize such a partition. This update modifies the underlying code so that system-config-lvm no longer crashes in this scenario. However, system-config-lvm still does not handle such partition names and such partitions cannot be initialized.
The system-config-lvm utility uses the dmsetup tool for obtaining information from Device Mapper Multipath. Output of dmsetup was designed to be parsed by scripts, however, with an update of device-mapper-multipath to version 1.02.74, this output was changed. As a consequence, system-config-lvm terminated unexpectedly with a traceback when used with Device-Mapper Multipath available on the system. This update modifies system-config-lvm to use a user-specified output which does not change across different versions. The system-config-lvm utility now works as expected.
All users of system-config-lvm are advised to upgrade to this updated package, which fixes these bugs.
