Hyper-V Volumes Management
|
|
=============================================
|
|
|
|
To enable the volume features, the first thing that needs to be done is to
|
|
enable the iSCSI service on the Windows compute nodes and set it to start
|
|
automatically.
|
|
|
|
sc config msiscsi start= auto
|
|
net start msiscsi
|
|
|
|
In Windows Server 2012, it's important to execute the following commands to
|
|
prevent having the volumes being online by default:
|
|
|
|
diskpart
|
|
san policy=OfflineAll
|
|
exit
|
|
|
|
How to check if your iSCSI configuration is working properly:
|
|
|
|
On your OpenStack controller:
|
|
|
|
1. Create a volume with e.g. "nova volume-create 1" and note the generated
|
|
volume id
|
|
|
|
On Windows:
|
|
|
|
2. iscsicli QAddTargetPortal <your_iSCSI_target>
|
|
3. iscsicli ListTargets
|
|
|
|
The output should contain the iqn related to your volume:
|
|
iqn.2010-10.org.openstack:volume-<volume_id>
|
|
|
|
How to test Boot from volume in Hyper-V from the OpenStack dashboard:
|
|
|
|
1. Fist of all create a volume
|
|
2. Get the volume ID of the created volume
|
|
3. Upload and untar to the Cloud controller the next VHD image:
|
|
http://dev.opennebula.org/attachments/download/482/ttylinux.vhd.gz
|
|
4. sudo dd if=/path/to/vhdfileofstep3
|
|
of=/dev/nova-volumes/volume-XXXXX <- Related to the ID of step 2
|
|
5. Launch an instance from any image (this is not important because we are
|
|
just booting from a volume) from the dashboard, and don't forget to select
|
|
boot from volume and select the volume created in step2. Important: Device
|
|
name must be "vda".
