Usage: %s command <params>
|
|
|
|
initialise [dev] [[ext_size]] - init. a physcial partition to store vd's
|
|
create [size] [[expiry]] - allocate a vd of specified size (and expiry)
|
|
enlarge [vdid] [extra_size] - enlarge a specified vd by some amount
|
|
delete [vdid] - delete a vd
|
|
import [filename] [[expiry]] - create a vd and populate w/ image from file
|
|
export [vdid] [filename] - copy vd's contents to a file
|
|
setexpiry [vdid] [[expiry]] - update the expiry time for a vd
|
|
list - list all the unexpired virtual disks
|
|
undelete [vdid] [[expiry]] - attempts to recover an expired vd
|
|
freespace - print out the amount of space in free pool
|
|
|
|
notes:
|
|
vdid - the virtual disk's identity string
|
|
size - measured in MB
|
|
expiry - is the expiry time of the virtual disk in seconds from now
|
|
(0 = don't expire)
|
|
device - physical partition to 'format' to hold vd's. e.g. hda4
|
|
ext_size - extent size (default 64MB)
