Constants

Types

type Disk

type Disk struct {
	// DevPath is the /dev/sdX entry of the disk
	DevPath string
	// DiskSize is size of disk in bytes
	DiskSize uint64
	// LogicalBlockSize is the block size of the disk normally 512 or 4k
	LogicalBlockSize uint64
	// contains filtered or unexported fields
}

Disk struct represents a disk which needs to be partitioned

func (*Disk) CreatePartitionTable

func (d *Disk) CreatePartitionTable() error

CreatePartitionTable create a GPT header on the disk

func (*Disk) CreateSinglePartition

func (d *Disk) CreateSinglePartition() error

CreateSinglePartition creates a single GPT partition on the disk that spans the entire disk
