RHEL10: re-installing a system automatically using a kickstart fails with error "The object with LVM ID xxx doesn't exist"

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 10.0
    • anaconda
    • kickstart

Issue

  • When reinstalling a system using a kickstart and custom partition layout, the reinstallation fails while configuring the storage with the following error message

    Error

An error occurred while activating your storage configuration.

The object with LVM ID '<VG>/<LV>' doesn't exist

Resolution

The solution is to delete the existing volume groups, through using a %pre script, as shown in the example below:

%pre --interpreter=/bin/bash --erroronfail --log=/tmp/ks-pre.log

# TODO: Here below adjust to the list of devices that are to be reformatted:
DEVICES=( /dev/mapper/mpatha /dev/sda /dev/sdb /dev/sdc /dev/sdd )
vgnames=()
while read pv vg; do
  for dev in ${DEVICES[@]}; do
    if [[ "$pv" == $dev[0-9]* ]]; then
    vgnames+=( $vg )
        break
    fi
  done
done <<< $(pvs --noheadings -o pv_name,vg_name)

for vg in $(printf "%s\n" ${vgnames[@]} | sort -u); do
  vgremove -ff $vg
done
%end

Root Cause

The issue is tracked by JIRA RHEL-95367 - Cannot reinstall system with kickstart, getting "The object with LVM ID xxx doesn't exist".

As of writing, it seems that there is a race occurring when Anaconda re-formats the disks and deletes the existing logical volumes.
