[linux-lvm] PV Resizing

[linux-lvm] PV Resizing

[Monty Taylor]

Hello.

I've managed to get myself into a rather funny spot -- I use LVM to
provide administrative flexibility, but I didn't account for one
possibility. I'm hoping someone has an idea...

I have a machine with a single hard drive. I have three partitions,
boot, swap, and the lvm partition. I now need to install a windows
partition... (damn CAD program won't run under WINE) Is there _any_ way
to resize the PV from under LVM? (Like with parted or something) so I
can create another partition? 

Thanks in advance.
Monty

[linux-lvm] PV resizing

[Yann Droneaud]

Hi,

First, sorry to bother you with my stupid question.

I have a PV set in a partition (dos partition table).

Can i resize (grow) this partition so that the PV become bigger, 
and new space will be available to the VG the PV is currently inside.

To summary, will the PV/VG take account of the new partition size ?
I would know about LVM 1 and LVM 2.

Otherwise i will have to remove my current VG.

Regards.

Why not make another partition, turn that into a PV and add that
PV to the VG?

Instead of fiddling with pvresizing, can you create a new partition 
using the extra space and add it to the VG using vgextend?
