Increasing the size of filesystems would be easier if there was Logical Volume Manager (LVM) in use. Task: server-minimal, cloud-image, ubuntu-live, server. Therefore, you have to free the space after the partition in order to increase it. Description: Linux Logical Volume Manager Description-md5: 9df95d102d2b0aad5aff13603ef0cb3f. The reason why you have to do all of this is because the MD devices consist of disk partitions, and partitions are single areas in the hard disk.

Re-create /dev/sda4 and /dev/sdb4 partitions and create RAID array on top of them.

Use mdadm -grow to increase the size of /dev/md1 to match the size of underlying partitions.

Increase the size of /dev/sda3 and /dev/sdb3 partitions to the size you want.

Delete the /dev/md2 device and partitions /dev/sda4 and /dev/sdb4 which are the RAID members.

Copy all contents of /dev/md2 to another place.

Resizing the MD device is a more complex process: The recommended way to avoid the space problem in your situation is to move existing directories to the filesystem in /dev/md2, and use symlinks to point to the new directory. We followed so many tutorials but no luck resizing /dev/md1. Question is though, how can we run away from this? Is there a way to use /dev/md2 beside /dev/md1 so that we don't encounter low space disk issues or even shrink /dev/md2 and grow /dev/md1? The problem is we run out of space everytime we want to install or run something new on /dev/md1 which is our main partition.

n homesnap is the name of our new logical volume (snapshot device) L 1G is the size of our snapshot, so it supports to 1GB of changes (remember the above important note). After a while we recognised that our main RAID partition has only 20GBs while other partition has more than 200GBs. To create a snapshot we can use a command like: lvcreate -s -n homesnap -L 1G /dev/My-vg/home. Start the VM again.Recently we configured an Ubuntu 16.04 on Server.Use the GUI to expand the drive to something reasonable, like 128 GB.(If this option is disabled, you need to go back and delete any checkpoints for the VM in the Hyper-V Manager just select the VM and right click the checkpoint in the checkpoint field below.) Use Hyper-V Manager to select the Settings of the Virtual Machine, select the Hard Drive option and Edit under Virtual hard disk.

However, if this method is used, you may end up with a tiny Ubuntu virtual disk that will not be useful for any serious work and it is less obvious than the initial setup how to increase the size of this disk. It is quick and easy to use Hyper-V Quick Create to get an Ubuntu virtual machine running on a Windows 10 computer.
