Functions ¶

func FlattenedBlockDevices ¶

func FlattenedBlockDevices(bs []BlockDevice) map[string]BlockDevice

Types ¶

type BlockDevice ¶

type BlockDevice struct {
	Name      string        `json:"name"`
	KName     string        `json:"kname"`
	Type      string        `json:"type"`
	Model     string        `json:"model,omitempty"`
	Vendor    string        `json:"vendor,omitempty"`
	State     string        `json:"state,omitempty"`
	FSType    string        `json:"fstype"`
	Size      string        `json:"size"`
	Children  []BlockDevice `json:"children,omitempty"`
	ReadOnly  bool          `json:"ro,omitempty"`
	Serial    string        `json:"serial,omitempty"`
	PartLabel string        `json:"partLabel,omitempty"`
}

BlockDevice is the block device as output by lsblk. All the fields are lsblk columns.

func (BlockDevice) HasChildren ¶

func (b BlockDevice) HasChildren() bool

HasChildren checks if the disk has partitions

type BlockDeviceInfo ¶

type BlockDeviceInfo struct {
	IsUsableLoopDev bool
}

type BlockDeviceInfos ¶

type BlockDeviceInfos map[string]BlockDeviceInfo

type HostLSBLK ¶

type HostLSBLK struct {
	exec.Executor
	// contains filtered or unexported fields
}

func NewDefaultHostLSBLK ¶

func NewDefaultHostLSBLK() *HostLSBLK

func NewHostLSBLK ¶

func NewHostLSBLK(executor exec.Executor, lsblk, losetup string) *HostLSBLK

func (*HostLSBLK) BlockDeviceInfos ¶

func (lsblk *HostLSBLK) BlockDeviceInfos(ctx context.Context, bs []BlockDevice) (BlockDeviceInfos, error)

func (*HostLSBLK) IsUsableLoopDev ¶

func (lsblk *HostLSBLK) IsUsableLoopDev(ctx context.Context, b BlockDevice) (bool, error)

IsUsableLoopDev returns true if the loop device isn't in use by Kubernetes by matching the back file path against a standard string used to mount devices from host into pods

func (*HostLSBLK) ListBlockDevices ¶

func (lsblk *HostLSBLK) ListBlockDevices(ctx context.Context) ([]BlockDevice, error)

ListBlockDevices lists the block devices using the lsblk command

type LSBLK ¶

type LSBLK interface {
	ListBlockDevices(ctx context.Context) ([]BlockDevice, error)
	IsUsableLoopDev(ctx context.Context, b BlockDevice) (bool, error)
	BlockDeviceInfos(ctx context.Context, bs []BlockDevice) (BlockDeviceInfos, error)
}
