HOWTO: resize a XEN virtual disk
This document (3786220) is provided subject to the disclaimer at the end of this document.
- Stop the virtual machine whose storage needs to be enlarged.
- Be smart & safe: Make a copy of the image file! Work on the copy, not the original.
- Increase the size of the virtual disk image:
# dd if=/dev/zero bs=1G count=1 >> your_disk_fileThis example adds 1GB of additional space to the virtual disk image.
- Resize the filesystem on the disk using the filesystem's resizing tools. In order to make sure the filesystem is clean, force a filesystem check first.
Here is an example for the ext3 filesystem:# e2fsck -f the_disk_file
# resize2fs the_disk_file
- Restart the virtual machine
