[linux-lvm] Converting my Root file system to LVM

[Rupert Heesom]

Many thanks for the 2 replies!

Well, since I had the same problem as Steve, I implemented his solution.

Tnx, Steve for the easy howto of your's below.
BTW, what on earth is that "mount -o loop" command?

As I tap on my keyboard, I am working inside of my new LVol, so it
worked, guys!

Since my LVol is on my 2nd disk, next, I think I'll try extending my
Lvol back to cover my 1st disk as well.

One more bit of help, if you can? -

I want to pvmove the file contents of my 2nd disk (/dev/sdb) to my 1st
disk (/dev/sda).  My 1st disk is nice & quiet!  Now the lvm-howto
specifies my next step (adding the "old partition" into the Lvol) as --

pvcreate /dev/sda   <using my device names>
vgextend vg /dev/sda

---  Seeing as I want to do a pvmove of data from /dev/sdb to /dev/sda,
when would I do the pvmove?   As I understand LVM, I need to have the PV
created and integrated into the VG before I can use pvmove - is this
correct?   Then, once pvmove is used, I can then extend the LV & file
system to cover both PVs using e2fsadm, right?

Well, it seems not all had the same problem, so I don't know!!??
