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.
