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
cfdisk /dev/sda ### for example if the new partition is /dev/sda3 pvcreate /dev/sda3
or assign the whole new disk to lvm
cfdisk /dev/sdb ### for example if the new partition is /dev/sda3 pvcreate /dev/sdb
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
vgextend base /dev/sda3
check with pvscan
if the extend was successfull
Now we extend the “data” partition to 11.5 GB. See man lvextend for other options
lvextend -L 11.5G /dev/base/data
now we have to grow the filesystem /data
xfs_growfs /data
