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!

Hi,
I had this before and what I dit was reformat and recreate the lvm
because the vgchange -ay dit nor work with me also
If thare is no data on this disk this is the a way
with "vgchange -ay" will an rescan be executed
But I suggest that you read carefully the man because I don't now what
Will happen when thare is an problem
I used vgchange -ay in the past without problems but I don't guarantee
(because of production)
You will best wait for an second opinion because I'm not that specialist
but here was my experience (of last week)
(My OS was fedora5)

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 Thomas,
Depending on how recent your version of LVM2 is, you can use pvresize to
do this:
# pvresize /dev/hda2
This will autodetect the new size of the PV and grow it accordingly. One
thing I noticed was that after fdisking the partition, a reboot was
needed to get kernel to see the new size - partprobe does not seem to be
sufficient.
That might have been a quirk though - check the partition sizes in
/proc/partitions to be sure.
Thanks,
Bryn.

Hi,
many thanks for your mail.
Got Version 2.01.04-5 on debian stable.
pvresize exist in the unstable tree of debian with Verson 2.02xx
Is there any other chance to resize the pv without pvresize?

The pvresize tool is the right way to do this. You'd need to hack the
metadata by hand otherwise - updating your LVM2 tools even temporarily
to allow you to do this is probably an easier path.
Cheers,
Bryn.
