- No, it contains basically a copy of the VGDA that is on
- the disk. This file is maintained by liblvm.a for faster
- response on lvm commands. That way you don't have to
- go to the disk every time for a query. If you remove this
- file it will be automatically rebuilt the next time you
- run an LVM command.
