Data Wiping

by Bytes

dd if=/dev/zero of=/dev/sdX bs=${block_size} count=${End - Start} seek=${Start} status=progress

by Sectors

dd if=/dev/zero of=/dev/sdX bs=${block_size} count=${sectors} status=progress

LVM Partitioning

• pvcreate /dev/sdX ...

• vgcreate ${group_name} /dev/sdX /dev/sdX create volume group

• lvcreate -L ${size} -t ${group_name} -n ${name} create logical volume

Remove Volume Group

• vgchange -a -n ${group_name} deactivate
• vgremove ${group_name}

Removing Logical Volume

• lvs see volumes
• lsblk see mountpoint
• lvremove ${volume_group}/${logical_volume}
