Enabling Cinder Backup Services In Openstack

Resolving The Problem

Cinder backup service is only in a HA environment. There are 2 options to enable this feature.

Option A

To enabled cinder backup service on single controller node:

1. Enable cinder backup service in environment file, add the following attributes:
"block-storage": {
"backup": {
"enabled": true
},
"debug": "False",
"verbose": "True",
"volume": {
"create_volume_group": false,
"volume_group_size": 40,
"iscsi_ip_address": "127.0.0.1"
}
2. Add cinder backup recipe in topology file for controller node
"runlist": [
"role[ibm-os-single-controller-node]",
"recipe[openstack-block-storage::backup]",
"role[ibm-os-prs-ego-master]",
"role[ibm-os-prs-controller-node]"
]
3. Update the topology file with knife command.

Option B
Modify the role[os-block-storage], add cinder backup role to the role.

1. Create a new role[os-block-storage-backup], prepare follow json file named os-block-storage-backup.json
{
"name": "os-block-storage-backup",
"description": "OpenStack Block Storage backup service",
"json_class": "Chef::Role",
"default_attributes": {

},
"override_attributes": {

},
"chef_type": "role",
"run_list": [
"role[os-base]",
"recipe[openstack-block-storage::backup]"
],
"env_run_lists": {

}
}
2. Run "knife role from file os-block-storage-backup.json" to update the new role
3. Edit the role[os-block-storage], add role[os-block-storage-backup] to the list.
*Run "knife role edit os-block-storage"
*Add role[os-block-storage-backup] to run list
{
"name": "os-block-storage",
"description": "Configures OpenStack block storage, configured by attributes.",
"json_class": "Chef::Role",
"default_attributes": {

},
"override_attributes": {

},
"chef_type": "role",
"run_list": [
"role[os-base]",
"role[os-block-storage-api]",
"role[os-block-storage-scheduler]",
"role[os-block-storage-volume]",
"role[os-block-storage-backup]",
"recipe[openstack-block-storage::identity_registration]"
],
"env_run_lists": {

}
}
*Save and exit.
4. Enable cinder backup in environment file and then Update the topology file with knife command.
