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?
Thanks, Bernard

Looks like xvda2 was resized. You should now have an added 5GB worth of unallocated extents in the vg
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]

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

How do you resize the partition without loosing data?
gparted does not support LVM.

gparted does not support LVM.
It is preferrable to create PV on the whole disk also to manage these kind of situations. In case I have to manage with partitions, the must is that you can do it only if it is the last partition, and you are ok. Normally I use fidsk and I first delete the last partition and then without exiting the utility I create again it using the same starting point and the new larger end. For this, take care of using option to show sectors and not cylinders ("u" switches between the two options) and print your partition layout ("p" comamnd), so that you can set exactly the same starting point of the new xvda2 partition otherwise you will have destroyed it and LVM layer would not be able to identify it (also the type if now it is 8e for Linux LVM). Eventually you will have to run also the command
partprobe /dev/xvda
to align os with new partition layout
Take care and read well (also on other sources on internet in case). Also backup your partiion layout before making changes with
sfdisk -d /dev/xvda > part_table.before
and compare with what you have after.
HIH, Gianluca
I usually use the whole disk a PV but this disk has the /boot partition which cannot be LVM.
I decided to simply use the third partition as another PV and extended the VG.

If you don't trust yourself to do it right, just create a new partition on the disk, pvcreate it, add it to the existing volume group.

Dunno 'bout gparted, but parted->t, if you ask for help, it lists types, and linux lvm is one type. A quick search tells me partition type e1.
