The issue happens because of a bug in the code, which was fixed Upstream by commit 728c2b000efd79c9e6f8cd82e1bbcded79c1f57d.
Version-Release number of selected component (if applicable):
rear-2.6-9.el8.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Setup a system with LUKS encrypted /dev/rhel/root and /dev/rhel/swap
# Disk partitioning information
part pv.356 --fstype="lvmpv" --ondisk=vda --size=19455
part /boot --fstype="xfs" --ondisk=vda --size=1024
volgroup rhel --pesize=4096 pv.356
logvol / --fstype="xfs" --size=10240 --encrypted --label="ROOT" --luks-version=luks2 --name=root --vgname=rhel
logvol swap --fstype="swap" --size=2048 --encrypted --luks-version=luks2 --name=swap --vgname=rhel
2. Create/setup a LUKS key for automatic unlocking
# dd if=/dev/urandom of=/lukskey bs=1K count=4
# chmod 400 /lukskey
# cryptsetup luksAddKey /dev/rhel/root /lukskey
[...]
# cryptsetup luksAddKey /dev/rhel/swap /lukskey
[...]
# cat /etc/crypttab
