Hi,

/etc/lvmpvg is an ascii file.
You can edit it manually changing the current device files with the new device files. After that you can see it by vgdisplay -v .
All details in man lvmpvg.

Best regards,
Fabio

The PVG is used for mirroring, to make it easier to find "mirroring pairs". Just to prevent your mirrors are on the same bus.

Do you use LVM mirroring?

Hi:

You can easily query your server to collect the current 'lvmpvg' information into a file that you can further edit. Do something like:

# VGS=`vgdisplay -v|grep "LV Name"|awk -F"/" '{print $3}'|sort -u`

# for VG in ${VGS} do
> vgdisplay -v ${VG}|sed -ne '/Physical volume groups/,$p' >> /tmp/lvmpvg
> done

You will need to edit the resulting '/tmp/lvmpvg' fiels, but it will provide the basis of what you need.
