I'm searching how to wipe all drives with > parted or fdisk. In an external shell script. I just do a simple dd (I still use msdos partitioing): dd if=/dev/zero of=$DEVICE bs=512 count=1 >/dev/null 2>&1 Then I use sfdisk with values calculated for the correct stripe size depending on the server RAID. Then I format with a stripe-width and optionally -m 0. I only let the ks do the mounting. Disclaimer: did not test with CentOS 6 yet... > clearpart --all --initlabel needed since you already put one in your partinfo file? JD
