Well, I hardly need to activate or deactivate LVM volume groups. But when I do, I also hardly remember the command required to do that. So hopefully, I can refer to this post should I need to perform one of these tasks in the future.
Since a volume group is activated by default when it is created, let’s start with a command to deactivate it.
# vgchange -a n example_volume_group
Like wise, to activate a volume group, use the following command:
# vgchange --activate y example_volume_group
If there is only thing that you or I need to remember is the vgchange command. To find the rest of option or argument, just run man vgchange.
