-======VM disk Expansion LVM+XFS========
+======VM disk Expansion LVM+XFS=======
+Expand the original disk or add a second vdisk from Infrastructure client.\\ If you want to perform a grow w/o reboot you have to add a second disk
+**THEN TAKE A SNAPSHOT!!!**
+then from on the vm either create an additional partirion on the free space. The partition type us 8e
+<code>
+cfdisk /dev/sda
+### for example if the new partition is /dev/sda3
+pvcreate /dev/sda3
+</code>
+or assign the whole new disk to lvm
+<code>
+cfdisk /dev/sdb
+### for example if the new partition is /dev/sda3
+pvcreate /dev/sdb
+</code>
+now you have to extend the volgroup. user ''lvdisplay'' to see which is the name of the group, in this example it's base and we assume the new partition is /dev/sda3
+<code>
+vgextend base /dev/sda3
+</code>
+check with ''pvscan'' if the extend was successfull
+Now we extend the "data" partition to 11.5 GB. See man lvextend for other options
+<code>
+lvextend -L 11.5G  /dev/base/data
+</code>
+now we have to grow the filesystem /data
+<code>
+xfs_growfs /data
+</code>
