UUID for partition identification (Ubuntu 6.10 and later).Many other article of same subject in Internet seems to be outdated on following parts: The purpose of this how-to is to describe how to move your Ubuntu Linux partition to a different partition either in same hard-disk or different hard-disk. Step 6: Update MBR to point the new grub.Step 3: Clone Ubuntu partition to new location.If you did not resize the filesystem in step 2Įnlarge the physical volume to occupy the whole available space in the partition:Įnlarge the logical volume and the filesystem (the file system can be mounted, works with ext4 and xfs). Enlarge the filesystem(s) in the partitions on the virtual disk Yoy will want to resize the 2nd partition first (extended):ģ. Number Start End Size Type File system Flags Warning: Not all of the space available to /dev/vda appears to be used, you canįix the GPT to use all of the space (an extra 268435456 blocks) or continueĪnother example without EFI using parted: Resize the partition 3 (LVM PV) to occupy the whole remaining space of the hard drive). (here we use VirtIO so the hard drive is named vda) Check that the kernel has detected the change of the hard drive size.If you want to enlarge a partition which is anywhere on the disk, use the offline method. Note that the partition you want to enlarge should be at the end of the disk. Here we will enlarge a LVM PV partition, but the procedure is the same for every kind of partitions. nothing seems to have happened as a result of using the resize command), go to the Windows command prompt and do a: shutdown -s -t 0 (This is a "normal" shutdown, as opposed to the "fast" shutdown that's the default for Win 8 and onwards.) After a reboot, you'll now see the ability to expand the disk. If you do not see the ability to extend the disk (i.e. Guest is Windows 10: logon as administrator and extend the disk and filesystem (Using Disk manager).logon as administrator and extend the disk and filesystem (Using Disk manager).Guest is Windows 7, Windows Vista or Windows Server 2008.Gparted have some warnings about some specific operations not well supported with windows guest - outside the scope of this document but read the warnings in gparted. (or simple delete the swap and partion andre create it again - but remember to activwate the swap agin (last step). With som linux clients you often need to enlarge the extended partion, move the swappartion, shrink the extended partion and enlarge the root partion. In gparted and possibly most other tools, LVM and Windows dynamic disc is not supportedīoot the virtual machine with gparted or similar tool, enlarge the partion and optionally the file system. Use gparted or similar tool (recommended) Enlarge the partition(s) in the virtual diskĭepending on the installed guest there is several diffent ways to resize the partions You will be presented with the option of increasing the disk size:Ģ. You can also select your VM from the list > Hardware > Hard Disk > Disk Action > Resize Linux should see the new size online without reboot with kernel >= 3.7 Windows should see the new size online without reboot with last virtio drivers. Linux should see the new size online without reboot with kernel >= 3.6 You can resize your disks online or offline with command line:Įxemple: to add 5G to your virtio0 disk on vmid100: Shrinking disks is not supported by the PVE API and has to be done manually.Īnother page (deleted) with overlapping content was Resizing disks | Archive qm command SystemRescueCD comes very handy for it, just add its iso as cdrom of your VM and set boot priority to CD-ROM. If you reduce (shrink) the hard disk, of course removing the last disk plate will probably destroy your file system and remove the data in it! So in this case it is paramount to act in the VM in advance, reducing the file system and the partition size. If you enlarge the hard disk, once you have added the disk plate, your partition table and file system knows nothing about the new size, so you have to act inside the VM to fix it. When you resize the disk of a VM, to avoid confusion and disasters think the process like adding or removing a disk platter. Resizing guest disk General considerations
