Hi,
you need to resize partition /dev/xvda2, afterwards resize pv.

I should have added the output of pvs:
[root ~]# pvs PV VG Fmt Attr PSize PFree /dev/xvda2 cl_vm731611 lvm2 a-- 9.00g 0
PFree still show 0. It should show 5g.
Also: [root ~]# pvdisplay /dev/xvda2 --- Physical volume --- PV Name /dev/xvda2 VG Name cl_vm731611 PV Size 9.00 GiB / not usable 2.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 2303 Free PE 0 Allocated PE 2303 PV UUID RtXa0c-07RP-RJ0V-kSjC-Tuo0-5QQv-sQIKlr
With fdisk, we can see the additional space has is there as it shows 16GB. The original disk had 10GB. [root ~]# fdisk -l /dev/xvda
Disk /dev/xvda: 16.1 GB, 16106127360 bytes, 31457280 sectors [snip]
Device Boot Start End Blocks Id System/dev/xvda1 * 2048 2099199 1048576 83 Linux /dev/xvda2 2099200 20971519 9436160 8e Linux LVM
vgs also shows 0 Free PE: [root@CTSSVN01 ~]# vgs VG #PV #LV #SN Attr VSize VFree cl_vm731611 1 2 0 wz--n- 9.00g 0
Thanks,

Hello,
I have a CentOS VM with only one disk on a Xenserver.
The disk has 2 partitions:
/dev/xvda1 -> /boot /dev/xvda2 -> a physical volume for LVM
I added 5GB to this disk via Xencenter to extend /dev/xvda2. Usually I just have to do "pvresize /dev/xvda" to have the additional space added
to
the disk. But for some reason it does not work for this disk.
[root ~]# pvresize /dev/xvda Failed to find physical volume "/dev/xvda". 0 physical volume(s) resized / 0 physical volume(s) not resized
[root ~]# pvresize /dev/xvda2 Physical volume "/dev/xvda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resized
Does someone have seen this problem before or could have an idea of the problem?
Looks like xvda2 was resized. You should now have an added 5GB worth of unallocated extents in the vg
