After doing a merge, deleting vdisk versions on PVS console does not delete them from vdisk store, no errors are seen on PVS console.
After deleting the versions, if we check store using File Explorer, we still see the vdisk versions present.
When replicating the vDisk versions between PVS servers, only the vhd, avhd, vhdx and vhdx and pvp files should be copied and not the lok file, which will generate a shared lock on the image on all PVS servers, preventing the files from being deleted.
