Will the following work? This is to test a function that uses LVM command. I have multiple scripts that are running in parallel. Each script is associated with one volume group. In the script are vgchange commands to activate the VG, file system mounts, file writes, and unmounts and then a deactivate of the VG. So it is possible to have a 2 instances of vgchange running at the same time (on different VGs). The reason I'm asking is that I am getting a failure where a deactivate does not work on a VG after running these scripts for about 12 hours.
