Lvm....


Hi,

Is it possible to keep one single physical volume or partition in two or more VGs?

Eg. if i want to use /dev/sda12 in LVM, is it possible to keep some part of it in VG1 and rest in VG2?

Regards,

your question doesn't make sense. if sda12 is an lvm parition then that is the PV. PV's contain VG's. multiple VG's can exist within a PV and a single VG can span multiple PV's, but you seem to be asking is a physical partition can be placed inside multiple VG's, which doesn't fit in with anything. if you're asking if a mountable LV can span VG's then no it can't, instead you would take 2 VG's and combine them to a single one, meaning you could have on LV across 2 physical devices.

Hi,

I am sorry for being confused.....what i want to know is when i create VG from two PV's i give command vgcreate vg1 /dev/sda1 /dev/sda2, now suppose i want to use some part of /dev/sda2 in vg1 and rest in vg2 so would it be right if i say vgcreate vg2 /dev/sda2 /dev/sda3?

Like you said "multiple VG's can exist within a PV", how is this possible??

Regards,
