Description
Provide nova-volumes to compute instances
Nova-volume is a service that allows you to give extra block level storage to your OpenStack Compute instances (using iSCSI and LVM)
Setup
Start the SCSI target daemon
$> sudo service tgtd start $> sudo chkconfig tgtd on
Ensure the nova-volume service is enabled
$> sudo nova-manage service list
How to test
Create a new 5GB volume
$> euca-create-volume -s 5 -z nova
View status of volumes, and wait for it to become 'available'
$> euca-describe-volumes
Make the storage available to the instance (note -d is the device on the compute node)
$> euca-attach-volume -i i-00000001 -d /dev/vdc vol-00000001
Expected Results
ssh to the instance and verify that the vdc device is listed in /proc/partitions
