Re: [Xen-users] Recovering space or "shrink" disk img?

disk option, does something similar need to be done in xen?
As previously commented, Linux doesn't recover "unused" space from a
file. However, if you shut down the guest then you can use "cp
--sparse=always" to "recover" sparse blocks. At the cost of temporarily
allocating all the sparse blocks on the disk you can do "dd if=/dev/zero
of=/tmp/hugefile; rm /tmp/hugefile" to make it possible to recover more
disk space. Overwriting blocks that are not in use and contain
non-null bytes is possible but I don't know of an easy way to do it
except in one or two special cases.
