Hi Everyone,

When providing Xen guests to cutomers, it is important to make sure thatthe LVM LV is "zeroed" before use. What is the correct syntax to do this?


I've tried:

dd if=/dev/zero of=/dev/vg0/lvname

however this seems to go on forever (unless my test machine is just slow!)

Any ideas?

Thanks
