If the /etc/lvm/devices/system.devices config file doesn't already exist (for example when it was not created during installation), creating a new LVM setup using Blivet will create the file and only add the new PVs which means the pre-existing PVs and VGs will be now ignored by LVM.

This can be easily reproduced by running a simple storage role playbook on a system without the  /etc/lvm/devices/system.devices config file:

—

• name: configure swap
   hosts: localhost

 vars:

 roles:
   - name: linux-system-roles.storage
 vars:
   storage_pools:
   - name: swapvg
     disks:
       - /dev/sdd
     volumes:
       - name: swap
         size: 80%
         fs_type: swap
         state: present

after running it, only the new PV on /dev/sdd will be added:

# cat /etc/lvm/devices/system.devices  

1. LVM uses devices listed in this file.
2. Created by LVM command vgcreate pid 244151 at Wed May 17 18:55:54 2023
   VERSION=1.1.2
   IDTYPE=devname IDNAME=/dev/sdd DEVNAME=/dev/sdd PVID=THQL8MFocGOkw4k6oC2zQo6J0l8rrRp1

Blivet should not create the devices file in this case or add all pre-existing PVs to it. A workaround to this issue is either running vgimportdevices --all before running the role or removing the devices file created by blivet afterwards.
