The gluster.features role implements GlusterFS usecases. This role implements following sub-roles:
- nfs_ganesha
- gluster_hc
- ctdb
- geo_replication
- GlusterFS
| Name | Choices | Default value | Comments |
|---|---|---|---|
| gluster_features_ganesha_haname | UNDEF | Name of the NFS Ganesha cluster. | |
| gluster_features_ganesha_volume | UNDEF | An existing GlusterFS volume which will be exported through NFS Ganesha | |
| gluster_features_ganesha_hostnames | UNDEF | A comma separated list of hostnames, these are subset of nodes of the Gluster Trusted Pool that form the ganesha HA cluster | |
| gluster_features_ganesha_viplist | UNDEF | public | A comma separated list of virtual IPs for each of the nodes specified above. |
| gluster_features_ganesha_masternode | UNDEF | One of the nodes from the Trusted Storage Pool, gluster commands will be run on this node. gluster_features_ganesha_masternode: "{{ groups['ganesha_nodes'][0] }}" - the first node of the inventory section ganesha_nodes will be used. | |
| gluster_features_ganesha_clusternodes | UNDEF | List of the nodes in the Trusted Storage Pool. gluster_features_ganesha_clusternodes: "{{ groups['ganesha_nodes'] }}" - The nodes listed in section ganesha_nodes in the inventory. |
| Name | Choices | Default value | Comments |
|---|---|---|---|
| gluster_features_hci_cluster | UNDEF | The cluster ip/hostnames. Can be set by gluster_hci_cluster: "{{ groups['hc-nodes'] }}", where hc-nodes is from the inventory file. | |
| gluster_features_hci_volumes | UNDEF | This is a dictionary setting the volume information. See below for further explanation and variables. | |
| gluster_features_hci_volume_options | UNDEF | This is not needed to be set by user, defaults are picked up. Set to override defaults. For default values see Gluster HCI documentation. | |
| gluster_features_hci_master | UNDEF | The REST host to be connected to (do not include `http'). This value will be ignored if glusterd1 is running on remote node. | |
| gluster_features_hci_port | 24007 | The glusterd2 port |
gluster.infra gluster.cluster
Creating a NFS Ganesha Cluster:
An example playbook to deploy NFS Ganesha. Note to gather_facts should be set to true.
---
- name: Setting NFS Ganesha
remote_user: root
hosts: ganesha_nodes
gather_facts: false
vars:
# Setting up NFS Ganesha
gluster_features_ganesha_haname: ganesha-ha
gluster_features_ganesha_volume: nfs_ganesha
gluster_features_ganesha_hostnames: "server1,server2,server3,server4"
gluster_features_ganesha_viplist: 10.70.44.121,10.70.44.122,10.70.44.123,10.70.44.124
gluster_features_ganesha_masternode: "{{ groups['ganesha_nodes'][0] }}"
gluster_features_ganesha_clusternodes: "{{ groups['ganesha_nodes'] }}"
roles:
- gluster.features
The above playbook assumes that a volume named nfs_ganesha is created and running.
If you are using GlusterFS 4.0 (glusterd2) ensure to install python-gluster-mgmt-client package on the remote master host.
Or create a directory glusterapilib on the remote host and copy the files volume.py, peer.py, common.py,init.py, excpetions.py under glusterapilib in a python searchable path.
