LINSTOR driver¶
The LINSTOR driver allows Cinder to use DRBD/LINSTOR instances.
Configuration¶
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:
