CentOS 7 for everything
I am probably never using lvm again. I have never not once actually benefited from its capabilities but this is probably the third or fourth time it has gotten in my way.
Issue is that I use the tools so rarely that I can't recall what needs to be done to properly mount the drives on another system and finding that info on the web is becoming more difficult as the noise in search results increases, more and more results are damn youtube videos, and my eyes are deteriorating. So its just fixed ext4 for me in the future, KISS.
End of rant. PC mobo died. Most data I need from it backed up to github, few things done that day didn't make the last commit and I'd rather not do them again.
Trying to mount drive on my laptop via USB interface. Which is easy when drives are plain old ext4 and not ext4 sitting on top lvm2.

That's the volume that I need to mount, it is in a VG named centos which is the same VG name as what the laptop I am using uses.
I have created /mnt/tmp which is where I want to mount it.
I am a bit worried both having the same VG name (centos) may be an issue, I believe the next step is suppose to be to use vgchange to activate the volume group but I am a bit hesitant to issuing that command with an argument that includes a volume group that is already active.
There is only one physical disc in the volume I need to mount, that was a lesson I learned the hard way previously - don't use multiple disks in a LVM2 volume without hardware redundancy. And with today's disk sizes it really isn't needed, not for what I do.
Where do I go from here to mount that volume?
Thanks.
