Note: if the commands above generate errors about needing to zero out the file system, use the following command:

root@filer01 ~# dd if=/dev/zero of=/dev/sda3

it take long time to wait for this. For example if my partition is 1GB - i think it is ok but if it is 500GB. How long that I need to wait for run this command. So do we have another solution for this.

Thanks,
