Help With LVM in Ubuntu
Good day all, I am new to this forum so I say hello.
I need some help with a little boo boo I made. I just installed a nice new fresh copy of Ubuntu Server, Installed Webmin and then started playing around trying to mount a 3tb drive to the system. Now I chose to install my setup and a LVM drive as I though it would give me allot of flexibility. But I seem to have messed it up now.
Basically I exended the root drive to all my free disk space. Here is my situation:
Code:
dylan@server:~$ sudo pvdisplay -m
[sudo] password for dylan:

Here is my Logical Volumes:

Now what I actully want to do is remove my 3tb drive from the LVM as I want to store important backups on it. And if say my 250 root drive dies I want to be able to plug the 3tb into a windows machine and read the data off it.
I really hope that I can fix this issue.
Thanks |
