[linux-lvm] what does 'orphan vg' mean?(global vg?)

["Busby.Cheung" <chaimvy 163 com>]

Hi All,

      While I was reading the lvm source code, I can't understand what 'is_orphan' means(like 'is_orphan_vg' function). what's the different between orphan and global vg?

      Thank you very much.

 

Best Regards,
