Re: changing path in mknod while creating new vg

Hi:

Why would you want to use a path other than '/dev'?

For starters, '/dev' isn't a separate mountpoint from '/' so it is always available even in single-user mode. I believe that the LVM module expects its device files in '/dev'.

Regards!

Shalom,

You should not change your path.

Your volume group may not work.

LVM utilities would not be able to properly maintain the structure.

This is not an area where you can be creative.

Re: changing path in mknod while creating new vg

Hi,

Curious question, I had never thought of it because as a rule I never tried to skip it. Well, I have reviewed mknod(2) and no validation of the path that references should be "/dev". In any case I urge you to order and for reasons of standard definitions of the system you do not consider this possibility.

About the impact on the system will surely be chaos!

Rgds.
