What volumetype would I use in my kubernetes-gluster StorageClass for arbiter-3 volumes?
If you want to configure Gluster volumes manually, there is no difference for Kubernetes what to mount - the regular GlusterFS volume or the GlusterFS Arbiter-3 volume. So, Volume Type should be glusterfs and you need to provide only the Volume name. Here is the example, more information is here:
"volumes": [
{
"name": "glusterfsvol",
"glusterfs": {
"endpoints": "glusterfs-cluster",
"path": "kube_vol",
"readOnly": true
}
}
]
If you want Kubernetes to provision Gluster volumes automatically, you need to dig deeper. Use these instructions from GitHub.
In the parameters section of the StorageClass you can
volumeoptions: user.heketi.arbiter trueAny PVCs provisioned through that StorageClass will have one arbiter and two data bricks.
