Maybe there is a better way to do this, so let me describe the whole problem. I put
/home directories on separate LV. It happened that the
/ LV get out of space. I then backup my
/home and are trying to remove it to be able to resize
/. However, when I did login to root tty and try to umount the
lvchange -a n /dev/trixxxy-vg/home I get prompt that this logical volume is in use.
Logical volume trixxxy-vg/home contains a filesystem in use.
/root were links to
/home/user/ relevant, so I thought that can cause the problem, but after I removed them, nothing have changed.
I guess there is an way to check what is using the particular logical volume that I am not aware of. Or is there a way to force remove such logical volume?
