xen-resize-guest

XEN-RESIZE-GUEST(8)					 Perl Programmers Reference Guide				       XEN-RESIZE-GUEST(8)

NAME

       xen-resize-guest - Resize a loopback or LVM based xen guest.

SYNOPSIS

	 xen-resize-guest [options]

	 Help Options:
	  --help     Show help information.
	  --manual   Read the manual for this script.
	  --version  Show the version information and exit.
	  --verbose  Show diagnostic output.

	 General Options:
	  --add      Specify the amount of space to add, e.g. --add=1gb
	  --dir      Specify the path to the loopback image root.
	  --force    Force the resize to happen without a last-chance delay.
	  --hostname Specify the hostname of the guest to resize.

OPTIONS

       --add Specify the amount of storage to add to the primary disk.
       --dir Specify the directory where the loopback files are based.
       --force Don't pause for 10 seconds prior to commencing.
       --help Show help information.
       --hostname Specify the hostname to delete.
       --lvm Specify the volume group to use.
       --manual Read the manual for this script.
       --version Show the version number and exit.

DESCRIPTION

	 This tool will ease the resizing of Xen guests, whether they are based
	upon loopback files or LVM partitions.

	 Whilst the process of resizing a guest is pretty simple it can be fiddly
	to do the steps correctly in the right order:

       1.  Shutdown the guest.	2.  Unmount the volume, if it is mounted.  3.  Add to the space.  4.  Check the filesystem.  5.  Resize the
       filesystem.  6.	Restart the guest.

	 More than once I've heard of users making mistakes and breaking their
	filesystems; hence this tool.
