If your filesystem is very old, created with an older build of mkfs.ext2, it may not be configured for online resize (missing -O resize_inode flag вЂ“ more recent versions of mkfs.ext2 automatically reserve space for block group descriptor tables, older versions ~2007/8 may not) and thus these steps wonвЂ™t work.

There is a caveat that your root filesystem (or the one youвЂ™re extending) must be the last one on disk so it can growВ contiguously into the free space. Do an online resize of the filesystem to use the new space.Extend the size of the partition on the physical disk.If your VM is not using LVM, the steps youвЂ™ll perform are: IвЂ™m going to take the example of a Linux guest under VMware Workstation though this should apply to most hypervisors and flavors of Linux. dd bs=512 count=2811904 if=my-original-raw-imagefile.img of=my-resized-raw-imagefile.One of the great things about working with virtual environments is that if you start to run out of space in a virtual machine, it is usually trivial to extend your disk. In our partition table we can see that our blocks are 512 bytes long, and we have a total number of 2811903 blocks to dump вЂ¦ doing the actual dump is done with dd which just reads raw blocks of data and dumps them somwhere. Now list our partition table so we have an idea what to dump: Now that the resize operations have been done in our raw disk image, we will dump the partitions to a smaller image.ДЇirst remove our loop device for the image, as it will interfere with the dump process: sudo losetup -d /dev/loop0 We can use for example gparted to resize the file systems contained in the partitions of our image: gparted /dev/loop0Дo any resize operation that you would like to have for your partitions and apply them, in my case I needed to trim down my image size as small as possible. Now that we have set-up our raw imagefile as a loop device, we can run filesystem tools on it.

This will mount /dev/loop0 as a вЂvirtual raw diskвЂ™ and itвЂ™s containing partitions accordingly as /dev/loop0p1 and /dev/loop0p2 To mount the image as a loop device: sudo losetup -find -show my-raw-imagefile.img

We gather from the partition table that we have two available partitions in the image file.Д«efore we can make any modification to the partitions or filesystems in our image, we will first need to mount the image as a loop device, which will install the required dev entries to address our partitions with other software as gparted. You can list the partition table of an image file with the following command: fdisk -l my-raw-imagefile.img Now reboot your station and verify if the loop devices are available with: ls /dev/loop* for ubuntu 16.04 LTS sudo losetup -Pf disk_image.raw Now execute to activate:, reboot and verify with update-grub2

On Ubuntu, this function is baked into the linux kernel, and this functionality can be enabled in the following way: edit /etc/default/grubДЄs last parameter on the following line: GRUB_CMDLINE_LINUX_DEFAULT='' Not only will we need to mount the image as a loop device, but we also need to make sure that our loop device will auto create additional device entries for the partitions detected on our image. If we want to modify partitions and file systems in our disk image file, we will need to mount the image as a so-called loop device in linux.
