After replacing it with a new volume group and deactivating the old one, the mount point, now belonging to the new volume group, gets unmounted accidentally. [Fix] A patch set has been introduced to fix this issue: https://github.com/systemd/systemd/pull/23508 The related patches are as follows: 367a2597c351 core/device: store the original path dce2d35ce53d core/device: move several functions 4a1a1caf2192 core/device: always accept syspath change [Test Plan] 1. Set up a virtual machine with two volume groups: vg1 and vg2. root@lvm-focal:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 91.9M 1 loop /snap/lxd/24061 loop1 7:1 0 49.9M 1 loop /snap/snapd/18357 loop2 7:2 0 63.3M 1 loop /snap/core20/1828 loop3 7:3 0 44.4M 1 loop /snap/snapd/23545 loop4 7:4 0 63.8M 1 loop /snap/core20/2496 loop5 7:5 0 91.9M 1 loop /snap/lxd/29619 sr0 11:0 1 1024M 0 rom vda 252:0 0 500G 0 disk ├─vda1 252:1 0 1M 0 part ├─vda2 252:2 0 2G 0 part /boot └─vda3 252:3 0 498G 0 part └─ubuntu--vg-ubuntu--lv 253:2 0 100G 0 lvm / vdb 252:16 0 20G 0 disk ├─vdb1 252:17 0 9.5G 0 part │ └─vg1-lvol0 253:0 0 2G 0 lvm └─vdb2 252:18 0 10.5G 0 part └─vg2-lvol0 253:1 0 2G 0 lvmt 2. Add a mount point entry in /etc/fstab. /dev/mapper/vg1-lvol0 /mnt/xfs xfs defaults 0 0 3. Run `mount -av` to mount the specified mount point. 4. Unmount the mount point and rename the volume groups. umount /mnt/xfs vgrename vg1 vg1_old vgrename vg2 vg1; 5. Run `mount -av` again and verify that the mount point is successfully mounted. root@lvm-focal:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 91.9M 1 loop /snap/lxd/24061 loop1 7:1 0 49.9M 1 loop /snap/snapd/18357 loop2 7:2 0 63.3M 1 loop /snap/core20/1828 loop3 7:3 0 44.4M 1 loop /snap/snapd/23545 loop4 7:4 0 63.8M 1 loop /snap/core20/2496 loop5 7:5 0 91.9M 1 loop /snap/lxd/29619 sr0 11:0 1 1024M 0 rom vda 252:0 0 500G 0 disk ├─vda1 252:1 0 1M 0 part ├─vda2 252:2 0 2G 0 part /boot └─vda3 252:3 0 498G 0 part └─ubuntu--vg-ubuntu--lv 253:2 0 100G 0 lvm / vdb 252:16 0 20G 0 disk ├─vdb1 252:17 0 9.5G 0 part └─vdb2 252:18 0 10.5G 0 part └─vg1-lvol0 253:1 0 2G 0 lvm /mnt/xfs 6.
