This table contains the options supported by the Nexenta iSCSI driver.
| Configuration option = Default value | Description |
|---|---|
| [DEFAULT] | |
| nexenta_blocksize = | (StrOpt) block size for volumes (blank=default,8KB) |
| nexenta_host = | (StrOpt) IP address of Nexenta SA |
| nexenta_iscsi_target_portal_port = 3260 | (IntOpt) Nexenta target portal port |
| nexenta_password = nexenta | (StrOpt) Password to connect to Nexenta SA |
| nexenta_rest_port = 2000 | (IntOpt) HTTP port to connect to Nexenta REST API server |
| nexenta_rest_protocol = auto | (StrOpt) Use http or https for REST connection (default auto) |
| nexenta_rrmgr_compression = 0 | (IntOpt) Enable stream compression, level 1..9. 1 - gives best speed; 9 - gives best compression. |
| nexenta_rrmgr_connections = 2 | (IntOpt) Number of TCP connections. |
| nexenta_rrmgr_tcp_buf_size = 4096 | (IntOpt) TCP Buffer size in KiloBytes. |
| nexenta_sparse = False | (BoolOpt) flag to create sparse volumes |
| nexenta_sparsed_volumes = True | (BoolOpt) Create volumes as sparsed 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. |
| nexenta_target_group_prefix = cinder/ | (StrOpt) prefix for iSCSI target groups on SA |
| nexenta_target_prefix = iqn.1986-03.com.sun:02:cinder- | (StrOpt) IQN prefix for iSCSI targets |
| nexenta_user = admin | (StrOpt) User name to connect to Nexenta SA |
| nexenta_volume = cinder | (StrOpt) pool on SA that will hold all volumes |
To use Compute with the Nexenta iSCSI driver, first
set the volume_driver:
volume_driver=cinder.volume.drivers.nexenta.iscsi.NexentaISCSIDriver
Then, set the nexenta_host parameter and
other parameters from the table, if needed.
