Re: [linux-lvm] Question about Physical volume



HI Thomas
I normally create a vg with vgcreate, with these steps:
1) Create the physical volume:
    pvcreate /dev/sdb
    pvcreate /dev/sdc
2) Then create the Volume Group:
    vgcreate vg00 /dev/sdb /dev/sdc
3) Create the lv
    lvcreate -L 40960M -n lvxpto /dev/vg00
4) then mke2fs -j /dev/vg00/lvxpto
5) This way, if you need more space to create new lv or to extende lvxpto, you nedd to extend the vg00 with vgextend
 
I Hope that this helps you
Gonçalo

Hi,

is it possible to extend a phyiscal volume?

I have a strange problem, i resized the /dev/sda4 partion (8e Linux LVM)
from 130GB to 220GB. so far so good.

But with pvdisplay i still get the 130Gb Partion :

pvdisplay
--- Physical volume ---
PV Name               /dev/sda4
VG Name               msa
PV Size               130,98 GB / not usable 0
Allocatable           yes
PE Size (KByte)       4096
Total PE              33530
Free PE               6394
Allocated PE          27136
PV UUID               TnggaW-0rIL-JaRp-JiwR-ZRlP-JJ83-LOjHfg

Can i do something like a Rescan? that the Information will be updated.
The big problem is that on this server a productive data so i can´t
remove any partions.

thx!

-tom
