piraeus-operator VS examples

https://piraeus.io/ might be a good option rather than longhorn, check it out.

Linstor using https://piraeus.io/

For kubernetes I also tried https://piraeus.io/ which is a drbd-operator for kubernetes; it creates+mirrors LVM volumes between nodes. In my experience it was faster than ceph although not 100% stable; sometimes a volume would get stuck on a node and only a reboot could help.

Take a look at https://github.com/piraeusdatastore/piraeus-operator

A lot better.

A couple of years ago I could see volumes on Linstor getting completely stuck and unrecoverable whenever the network was getting busy or unstable. Nodes reboot were a nightmare too.

Have a setup now with their Piraeus operator[1], Kubernetes >= 1.20, rancher and calico, and it seems to be very stable. XFS have been giving better results too. Still, better not to try too many reboot loops on the nodes.

Then for the initators (k8s pods), just reference the builtin iSCSI CSI driver in your deployment's [volume config](https://github.com/kubernetes/examples/blob/master/volumes/iscsi/iscsi.yaml).

I am setting up a kubernetes lab using one node only and learning to setup kubernetes nfs. I am following kubernetes nfs example step by step from the following link: https://github.com/kubernetes/examples/tree/master/staging/volumes/nfs

It doesn't seem like there are a lot of good open source k8's projects. One I could find was the kubernetes/examples repo.

Kubernetes has a decent example of using GlusterFS for Volume storage: fun documentation link

Now let's deploy something that will return some results. Kubernetes has multiple example applications available in a Github repo. We are going to deploy the Guestbook App with these commands:

Following this example Kubernetes iSCSI Example, I created a new raw LUN and deployed the below pod manifest:
