Setting up the Storage Cluster
Identify a node where Storage manager will be deployed. This node can be one of the storage nodes, or it can be a spare node that is highly available.
Enable and start the kadalu-mgr
[root@server1 ~]# systemctl enable kadalu-mgr
[root@server1 ~]# systemctl start kadalu-mgr
The cluster configurations are stored in /var/lib/kadalu
. Since the storage manager is running in a single node, by default it is not highly available. Use kadalu-lite
Volume for high availability, or backup the Pool data in regular intervals. Refer "High availability" chapter (Coming soon) for more details.
No nodes are added to the cluster by default. Invite the node to become part of the Cluster by running the following command.
[root@server1 ~]# kadalu node add server1.example.com
Node server1.example.com added successfully
ID: 3befd57b-1d31-4664-94e9-f87bf7ce90f9
Default node endpoint is http://<nodename>:3000
. If it is different then provide the endpoint using --endpoint=ENDPOINT
option.
[root@server1 ~]# kadalu node add server1.example.com --endpoint=http://server1.example.com:3001
Node server1.example.com added successfully
ID: 3befd57b-1d31-4664-94e9-f87bf7ce90f9
Before inviting other nodes to join the cluster, start the kadalu-mgr
service.
[root@server2 ~]# systemctl enable kadalu-mgr
[root@server2 ~]# systemctl start kadalu-mgr
[root@server1 ~]# kadalu node add server2.example.com
Node server2.example.com added successfully
ID: 34aabcae-1052-4a78-91a5-d71c89458e8d
Run node list
to view the list of the nodes and their status.
[root@server1 ~]# kadalu node list

34aabcae-1052-4a78-91a5-d71c89458e8d server2.example.com http://server2.example.com:3000
Include the Status information
[root@server1 ~]# kadalu node list --status
