Identify the devices available from nodes and run the following command to add storage to Kadalu.
Note: if your host is running RHEL/CentOS 7.x series or Ubuntu/Debian older than 18.04, you may need to do below tasks before adding storage to kadalu.
$ # On CentOS7.x/Ubuntu-16.04 $ sudo dd if=/dev/zero of=/dev/sdc bs=512 count=1 $ sudo mkfs.xfs /dev/sdc
Once the device is ready, add it to kadalu pool. (note:
kube1 below is hostname, check yours by
kubectl get nodes).
$ kubectl kadalu storage-add storage-pool-1 --device kube1:/dev/sdc
Operator will start the storage export pods as required. And, in 2 steps, your storage system is up and running.
Check the status of Pods using,
$ kubectl get pods -n kadalu NAME READY STATUS RESTARTS AGE server-storage-pool-1-kube1-0 1/1 Running 0 84s csi-attacher-0 2/2 Running 0 30m csi-nodeplugin-5hfms 2/2 Running 0 30m csi-nodeplugin-924cc 2/2 Running 0 30m csi-nodeplugin-cbjl9 2/2 Running 0 30m csi-provisioner-0 3/3 Running 0 30m operator-6dfb65dcdd-r664t 1/1 Running 0 30m
