Hi,
Wow... I didn't know about "growpart" :)
I do, however, on XenServer (now XCP-NG) almost the same thing for
ages:
- shutdown the VM
- increase disk size on XCenter
- boot VM on maintenance mode (with DVD boot)
- do fdisk /dev/xvda, remove the desired partition (in your case 3),
and recreate it with the same initial block and occupying the rest of the
disk.
- make what's is need to use the new space on the partition, in my
case it's a LVM partition used as a PVE block. Than pvresize, vgextend,
etc...
Until now, no problems...
Att.,
Antonio.
