[Xen-users] Re: Will this work? (Zeroing free space)

[Aleix Dorca <adorca@xxxxxx>]

Thanks for your comments. I see that Martii you do almost exactly as I  
do. It's good to know it works as intended.
I've also tried sdelete on a small VM and the backup has dropped from  
5.6Gb to 3.4Gb on a 30Gb partition disk. Quite impressive.
I've just also found "zerofree". A linux utility I didn't know about  
that zeros free space on ext2/3 filesystems. The device has to be  
unmounted though.
Thanks again.

Aleix.
