Current LVM configuration: Unallocated physical volumes: * /dev/mapper/mpatha2 (21218MB) Volume groups: * rootVG (21218MB) - Uses physical volume: /dev/dasda2 (21315MB) - Uses physical volume: /dev/mapper/mpathc1 (21470MB) - Uses physical volume: [unknown] (21470MB) - Uses physical volume: [unknown] (21470MB) * rootVG (21470MB) - Uses physical volume: /dev/dasda2 (21315MB) - Uses physical volume: /dev/mapper/mpathc1 (21470MB) - Uses physical volume: [unknown] (21470MB) - Uses physical volume: [unknown] (21470MB) * rootvg (42685MB) - Uses physical volume: /dev/mapper/mpathb1 (21470MB) - Uses physical volume: [unknown] (214 When trying to remove that LVM using "Configure the Logical Volume Manager", it is not possible to remove logical volumes. The error "The logical volume swapLV on rootVG could not be deleted." is displayed. In syslog, you see the following messages: Apr 3 12:55:56 partman-lvm: Multiple VGs found with the same name: skipping rootVG Apr 3 12:55:56 partman-lvm: Use --select vg_uuid=<uuid> in place of the VG name. As you cannot use the suggested parameter in the installer, the system cannot be installed without manually removing the LVM setup with another shell.
