[linux-lvm] Where is the limit on Max VGs coming from?

[Kishore <kishore sampathkumar wipro com>]

Hi,

I wanted to know the reason for the limitation for Maximum number of
VGs, which is 100 currently.

If it was based on bits in minor number, I was under the impression that
it should have been 255 (where /dev/lvm occupies minor number 0 for the
LVM Character device interface).

Can someone clarify?

Thanks,
