Struct devicemapper::LinearDev

pub struct LinearDev {
    pub dev_info: DeviceInfo,
}

A DM construct of combined Segments

Fields

dev_info: DeviceInfo

Data about the device

Methods

impl LinearDev

Use DM to concatenate a set of blockdevs together into a /dev/mapper/xxx block device of continuous sectors.

fn new(name: &str, dm: &DM, block_devs: &[Segment]) -> DmResult<LinearDev>

Construct a new block device by concatenating the given block_devs into linear space. Use DM to reserve enough space for the stratis metadata on each DmDev.

fn name(&self) -> &str

DM name - from the DeviceInfo struct

fn dstr(&self) -> String

Get the "x:y" device string for this LinearDev

fn size(&self) -> DmResult<Bytes>

return the total size of the linear device

fn devnode(&self) -> DmResult<PathBuf>

path of the device node

fn teardown(self, dm: &DM) -> DmResult<()>

Remove the device from DM
