Member Function Documentation

◆ clone()

virtual LvmPv * storage::LvmPv::clone ( ) const
overridevirtual

Implements storage::Device.

◆ create()

LvmPv * storage::LvmPv::create ( Devicegraph * devicegraph)
static

Create a device of type LvmPv.

Usually this function is not called directly. Instead LvmVg::add_lvm_pv() is called.

See also
Device::create(Devicegraph*)

◆ get_all()

std::vector< const LvmPv * > storage::LvmPv::get_all ( const Devicegraph * devicegraph)
static

Get all LvmPvs.

◆ get_blk_device() [1/2]

BlkDevice * storage::LvmPv::get_blk_device ( )

Return the block device this physical volume is using.

Exceptions
Exception

◆ get_blk_device() [2/2]

const BlkDevice * storage::LvmPv::get_blk_device ( ) const

Return the block device this physical volume is using.

Exceptions
Exception

◆ get_lvm_vg() [1/2]

LvmVg * storage::LvmPv::get_lvm_vg ( )

Return the volume group the physical volume is used in.

Exceptions
Exception

◆ get_lvm_vg() [2/2]

const LvmVg * storage::LvmPv::get_lvm_vg ( ) const

Return the volume group the physical volume is used in.

Exceptions
Exception

◆ get_usable_size()

unsigned long long storage::LvmPv::get_usable_size ( ) const

Get the size of the PV usable for extents in bytes.

Can be 0 (if pe_start >= size of blk device).

Exceptions
Exception

◆ has_blk_device()

bool storage::LvmPv::has_blk_device ( ) const

Check whether the physical volume has a block device.

Normally this is the case, but LVM may report block devices as missing during probing.
