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
