In VMmanager you can enlarge the VPS disk size.
- Currently it is not possible to enlarge disk size on the RBD storage
- for enlarging disk size on File and NFS storages, you need to have libvirt 0.9.10 and later
Enlarging disk size
Browse to the Virtual machines module, select your VPS and click the "Disks" icon
Select your disk and click "Edit"
Enlarge the disk size. ATTENTION You cannot reduce the disk size
and click "OK"
Please note: set a lower boot priority for booting from the rescue disk
Connecting the rescue disk
SSH access the server and execute the following commands
root@vm:~# cd /nfsshare/iso/ root@vm:~# wget -O rescueFree.iso "ftp://ftp2.ru.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/9.2/FreeBSD-9.2-RELEASE-amd64-bootonly.iso" root@vm:~# wget -O rescue.iso "http://downloads.sourceforge.net/project/systemrescuecd/sysresccd-x86/4.0.0/systemrescuecd-x86- 4.0.0.iso?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fsystemrescuecd%2Ffiles%2Fsysresccd-x86%2F4.0.0%2Fsystemrescuecd-x86- 4.0.0.iso%2Fdownload%3Fuse_mirror%3Dhivelocity&ts=1392711625&use_mirror=citylan"
Or download other iso that you like
In the "Virtual disks" module click "ISO".
- For linux - rescue.iso
- For FreeBSD - rescueFree.iso
- For Windows you do not need to boot from ISO
Enlarging disk size on different systems
Boot from rescueFree.iso - LiveCD FreeBSD. Then select
Log in as root and execute (our disk is connected as vtbd0, we need the third section):
gpart recover /dev/vtbd0 gpart resize -i3 /dev/vtbd0 growfs /dev/vtbd0p3
Confirm that you want to enlarge the size. Connect ISO and boot into the system
Boot from rescue.iso. Select the first variant
Log in as root and open
We need the third action (type in the first letters, see comments after # ):
d # Delete the section (data won't be deleted) 3 # Section number n # Create a new section p # Primary 3 # Section number
Fdisk will select the correct first and last section, you will only double-press Enter
w # specify the new table on the disk
Run the disk check
e2fsck -f /dev/vda3
Enlarge the FS
That's all. Disable ISO and reboot
After you have enlarged the disk size, restart the VPS. Browse to Server Manager -> Disk Management
Right click to select your disk. Make Extend Volume
Confirm all the Wizard actons to enlarge the disk space
