Issue

You want to delete a logical volume but, when running the command "lvremove", you get the following output:

# lvremove /dev/datosvg/mngfileslv 
  Can't remove open logical volume "mngfileslv" 
#

The LV is unmounted and when you check the LV you can see that it is marked as "open"

# lvs /dev/datosvg/mngfileslv 
  LV         VG      Attr   LSize   Origin Snap%  Move Log Copy%  Convert 
  mngfileslv datosvg -wi-ao 100.50G
