Method	`GetUserspaceAccessUri`	Generate KVM userspace URIs to be used as `-drive file` settings.
Method	`Grow`	Grow the Volume.
Method	`Open`	Make the device ready for I/O.
Method	`Remove`	Remove the extstorage device.
Method	`Rename`	Rename this device.
Method	`SetInfo`	Update metadata with info text.

@classmethod
def Create(cls, unique_id, children, size, spindles, params, excl_stor, dyn_params, **kwargs): ¶

overrides ganeti.storage.base.BlockDev.Create

Create a new extstorage device.

Provision a new volume using an extstorage provider, which will then be mapped to a block device.

def __init__(self, unique_id, children, size, params, dyn_params, **kwargs): ¶

overrides ganeti.storage.base.BlockDev.__init__

Attaches to an extstorage block device.

def Assemble(self): ¶

overrides ganeti.storage.base.BlockDev.Assemble

Assemble the device.

def Attach(self, **kwargs): ¶

overrides ganeti.storage.base.BlockDev.Attach

Attach to an existing extstorage device.

This method maps the extstorage volume that matches our name with a corresponding block device and then attaches to this device.

def Close(self): ¶

overrides ganeti.storage.base.BlockDev.Close

Notifies that the device will no longer be used for I/O.

def GetUserspaceAccessUri(self, hypervisor): ¶

overrides ganeti.storage.base.BlockDev.GetUserspaceAccessUri

Generate KVM userspace URIs to be used as `-drive file` settings.

`base.BlockDev.GetUserspaceAccessUri`

def Grow(self, amount, dryrun, backingstore, excl_stor): ¶

overrides ganeti.storage.base.BlockDev.Grow

Grow the Volume.

Parameters
amount:integer	the amount (in mebibytes) to grow with
dryrun:boolean	whether to execute the operation in simulation mode only, without actually increasing the size
backingstore	Undocumented
excl_stor	Undocumented

def Open(self, force=False, exclusive=True): ¶

overrides ganeti.storage.base.BlockDev.Open

Make the device ready for I/O.

def Remove(self): ¶

overrides ganeti.storage.base.BlockDev.Remove

Remove the extstorage device.

def Rename(self, new_id): ¶

overrides ganeti.storage.base.BlockDev.Rename

Rename this device.

def SetInfo(self, text): ¶

overrides ganeti.storage.base.BlockDev.SetInfo

Update metadata with info text.

def Shutdown(self): ¶

overrides ganeti.storage.base.BlockDev.Shutdown

Shutdown the device.

def Snapshot(self, snap_name=None, snap_size=None): ¶

overrides ganeti.storage.base.BlockDev.Snapshot

Take a snapshot of the block device.
