Are you talking about /dev/vgname/lvname link or the links under
/run/vdsm/storage/domain/image/volume,
or /rhev/data-center/pull/domain/image/volume?

/dev/vgname/lvname is created by udev rules when lv is activated or deactivated.
To understand if this is the issue, can you show the output of:

pvscan --cache
lvs vgname
ls -l /dev/vgname

Both before the the merge, and after the merge was completed.

The lv should not exist, and the links should be deleted.

Links under /run/vdsm/storage or /rhev/data-center/ should be created
when starting a vm, and tore down when stopping a vm, hotunpluging
a disk, or removing a snapshot.

To understand if there is an issue, we need the output of:

tree /run/vdsm/stoage/domain/image
tree /rhev/data-center/pool/domain/images/image

Before and after the merge.

The links should be deleted.
