LINSTOR driver

LINSTOR driver

The LINSTOR driver allows Cinder to use DRBD/LINSTOR instances.


Set the following option in the cinder.conf file for the DRBD transport:

volume_driver = cinder.volume.drivers.linstordrv.LinstorDrbdDriver

Or use the following for iSCSI transport:

volume_driver = cinder.volume.drivers.linstordrv.LinstorIscsiDriver

The following table contains the configuration options supported by the LINSTOR driver:
