 Quobyte driver

Quobyte provides a software defined storage system running on plain Linux servers. Quobyte allows reconfiguration at runtime without storage service interruption. Storage behaviour is fully configurable via policies which also control automation and hardware independent configuration. Quobyte users can find more information via the documentation link at

This driver enables the use of Quobyte storage in a similar fashion as NFS. It supports basic volume operations, including snapshot and clone.

To use Block Storage with Quobyte, first set the volume_driver configuration option in the cinder.conf file:

volume_driver = cinder.volume.drivers.quobyte.QuobyteDriver

The following table contains the configuration options supported by the Quobyte volume driver.

Table 2.27. Description of Quobyte USP volume driver configuration options
Configuration option = Default value Description
quobyte_client_cfg = None (StrOpt) Path to a Quobyte Client configuration file.
quobyte_mount_point_base = $state_path/mnt (StrOpt) Base dir containing the mount point for the Quobyte volume.
quobyte_qcow2_volumes = True (BoolOpt) Create volumes as QCOW2 files rather than raw files.
quobyte_sparsed_volumes = True (BoolOpt) Create volumes as sparse files which take no space. If set to False, volume is created as regular file.In such case volume creation takes a lot of time.
quobyte_volume_url = None (StrOpt) URL to the Quobyte volume e.g., quobyte://<DIR host>/<volume name>
