[Xen-users] Clean deleted space in linux diks?

[James Pifer <jep@xxxxxxxxxxxxxxxx>]

We're moving to a new SAN where we can take advantage of thin
provisioning if desired. When we migrate our disks to the new SAN,
whether windows or linux, the disks consume the whole space. 

On Windows machines we can run sdelete by sysinternals on the Windows
drives, which I believe writes zeros in the deleted space. We can then
run a reclamation on the SAN disks and reclaim the deleted space. 

We run different version of SLES. Are there any similar tools for linux
or a way of doing this in linux so the deleted space can be reclaimed?

Any suggestions are appreciated.

Thanks,
James
