Description of problem:

In /dev/mapper/ directory, link to /dev/dm-x device not created after vgmknodes. A vgchange --refresh makes does create the link.

Version-Release number of selected component (if applicable):

lvm2-2.03.16-3.el9.x86_64
kernel-5.14.0-162.6.1.el9_1.x86_64

Steps to Reproduce:

[root@localhost ~]# lvs -ao +devices testvg
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert Devices
lvol0 testvg wi-a---- 508.00m /dev/sda(0)

• Remove and all comes back with vgchange --refresh:

[root@localhost ~]# rm -rf /dev/mapper/testvg-lvol0
[root@localhost ~]# vgchange --refresh testvg
[root@localhost ~]# ls -lah /dev/mapper/testvg-lvol0
lrwxrwxrwx. 1 root root 7 Jan 18 16:45 /dev/mapper/testvg-lvol0 -> ../dm-2

• But using vgmknodes, link does not come back:

[root@localhost ~]# rm -rf /dev/mapper/testvg-lvol0
[root@localhost ~]# vgmknodes
[root@localhost ~]# ls -lah /dev/mapper/testvg-lvol0
brw-rw----. 1 root disk 253, 2 Jan 18 16:46 /dev/mapper/testvg-lvol0

[root@localhost ~]# rm -rf /dev/mapper/testvg-lvol0
[root@localhost ~]# vgmknodes --refresh
[root@localhost ~]# ls -lah /dev/mapper/testvg-lvol0
brw-rw----. 1 root disk 253, 2 Jan 18 16:46 /dev/mapper/testvg-lvol0

• Even after trigger, link not re-created:

[root@localhost ~]# rm -rf /dev/mapper/testvg-lvol0
[root@localhost ~]# vgmknodes
[root@localhost ~]# ls -lah /dev/mapper/testvg-lvol0
brw-rw----. 1 root disk 253, 2 Jan 18 16:52 /dev/mapper/testvg-lvol0
[root@localhost ~]# udevadm trigger
[root@localhost ~]# ls -lah /dev/mapper/testvg-lvol0
brw-rw----. 1 root disk 253, 2 Jan 18 16:52 /dev/mapper/testvg-lvol0

Actual results:

No /dev/mapper link created

Expected results:

The vgmknodes command and vgmknodes --refresh command should recreate the link.
