This repository contains source files for the JovianDSS Cinder volume driver.
git clone https://github.com/Open-E/JovianDSS-CinderCopy open_e folder to your Cinder driver folder. For instance if your Cinder is located at /opt/stack/cinder/, the command will looks like:
cp -R JovianDSS-Cinder/joviandss /opt/stack/cinder/cinder/volume/drivers/open_eEdit with your favorite editor Cinder config file. It can be found at /etc/cinder/cinder.conf
Add the field enabled_backends with value joviandss:
enabled_backends=jdss-0
Provide settings to JovianDSS driver by adding 'jdss-0' description:

Now you should restart Cinder service.
Create new volume type according to the back end name provided previously:
$ cinder type-create jdss-0Response would be(ID is unique ID, you will have different value):
+--------------------------------------+-----------+-------------+-----------+
| ID | Name | Description | Is_Public |
+--------------------------------------+-----------+-------------+-----------+
| 70f92fa6-200d-42cf-b132-cbbd3d9c71a4 | jdss-0 | - | True |
+--------------------------------------+-----------+-------------+-----------+
Check the list of available types
$ cinder type-listResponse would be like:
+--------------------------------------+-------------+-------------+-----------+
| ID | Name | Description | Is_Public |
+--------------------------------------+-------------+-------------+-----------+
| 07a842ea-543c-455b-9688-327673a7b001 | lvmdriver-1 | - | True |
| 70f92fa6-200d-42cf-b132-cbbd3d9c71a4 | jdss-0 | - | True |
+--------------------------------------+-------------+-------------+-----------+
Now try to create volume:
$ cinder create --name my_test_volume --volume-type jdss-0 1Response would be like:

Now if you go to the JovianDSS Web interface you will see volume with name:
9720999dd1e147009ac15348b823acfc
All you need to add another JovianDSS Pool is to create a copy of JovianDSS config in cinder.conf file.
For instance if you want to add Pool-1 located on the same host as Pool-0.
You extend cinder.conf file like:
enabled_backends = jdss-0, jdss-1
[jdss-0]
volume_backend_name=jdss-0
chap_password_len=14
driver_use_ssl=True
iscsi_target_prefix=iqn.2016-04.com.open-e.cinder:
jovian_pool=Pool-0
jovian_block_size=64K
jovian_rest_send_repeats=4
san_api_port=82
target_port=3260
volume_driver=cinder.volume.drivers.open_e.iscsi.JovianISCSIDriver
san_hosts=192.168.0.40
san_login=admin
san_password=admin
san_thin_provision=True
[jdss-1]
volume_backend_name=jdss-1
chap_password_len=14
driver_use_ssl=True
iscsi_target_prefix=iqn.2016-04.com.open-e.cinder:
jovian_pool=Pool-1
jovian_block_size=64K
jovian_rest_send_repeats=4
san_api_port=82
target_port=3260
volume_driver=cinder.volume.drivers.open_e.iscsi.JovianISCSIDriver
san_hosts=192.168.0.50
san_login=admin
san_password=admin
san_thin_provision=True
Do not forget to change values of jovian_pool and volume_backend_name . Everything else remain the same.
To utilize High Availability feature of of JovianDSS:
- Configure Pool to high availability cluster
- Set
jovian_hostswith list ofvirtual IPsassociated with this Pool
For instance if you have Pool-2 with 2 virtual IPs 192.168.21.100 and 192.168.31.100 the configuration file will look like:
[jdss-2]
volume_backend_name=jdss-2
chap_password_len=14
driver_use_ssl=True
iscsi_target_prefix=iqn.2016-04.com.open-e.cinder:
jovian_pool=Pool-0
jovian_block_size=64K
jovian_rest_send_repeats=4
san_api_port=82
target_port=3260
volume_driver=cinder.volume.drivers.open_e.iscsi.JovianISCSIDriver
san_hosts=192.168.21.100, 192.168.31.100
san_login=admin
san_password=admin
san_thin_provision=True
