Thanks so much bro. I'm stuck with NFS Share after I upgraded my k8s version from 1.18 to 1.20. I have no idea why it cannot create pv. So this video helps me alot. Thanks again!.

Hi, I like all your videos. I am using as storage solution on my kubernetes homelab longhorn v1.1.0. It’s a great solution . It’s a powerful distributed block storage system. Now longhorn support readwritemany workloads. You can create backup and snapshots . Think about make a video about longhorn. Best Regards.
Thanks for the detailed explanation. I have followed the helm installation. after creating PVC, I am trying to extend the storage size. Even though allowVolumeExpansion is set to true.The PVC expansion is not reflecting. The change is there in the manifest file when I am looking for manifest file. Any idea why this is PVC expansion is not working?
your videos quite comprehensive and have helped me in setting an ELK cluster in k8s. thanks a lot i am facing an issue with nfs snapshot repo, have send a message in slack. could you pls take a look and provide some suggestion ?
Just saw your message in Slack. Can you provide me with more information. 1. What is your kubernetes cluster look like (how did you provision, cloud or local laptop, windows or Linux host) 2. What docs you followed for deploying ELK basically, if you could give me as much information as possible to help me recreate your set up in my environment, it would help troubleshoot
This is one of the great explanation. The kubernetes nfs provisioner, pvc and pv under nfs share are got created successfully. However, upon deploying test-pod.yaml file from the same github source with restartPolicy as 'Always', the pod is crashing with a message 'Restarting' is failing. Really appreciate if you can provide some suggestions and reasons.
ty! but i want to add that in rbac.ymal (or whatever u may call it) u need to add rights to get watch list create delete update endpoints. Without that i have some errors in provision-pod
Thanks for this helpful tutorial. It is like finding missing part in a jigsaw. Do you know any tutorial about iscsi and openfiler usage in kubernetes. Thanks again...
Hi Hasan, thanks for watching. I haven't come across any videos on iscsi/openfiler in kubernetes. Sure, there will be some docs lying around in the internet. Cheers.

Best video collection for k8s. Could you please help me that which persistent storage solution I can use if I have a 3 nodes k3s Lab setup on my laptop ?
Hi Ashu, thanks for watching. You don't have much option if you want to do that on your laptop. You can use NFS as shown in this video. Some kubernetes distribution like KinD, K3D, minikube all come with localpath provisioner pre-deployed so that you can start requesting and using persistent volumes without much effort

Hello, very good kubernetes domain and excellent explanation, I thank you for sharing your knowledge. One question, this solution that you explain in your video of dynamic provisioning using NFS (with ReadWriteMany) can be used on an AWS EC2 with an EBS ?. Before installing NFS for dynamic provisioning, you must prepare the disk with ext4 and LVM? Format. Thank you
Hi Juan, thanks for watching. I didn't dive deeper into this as mostly in real world (production), you won't be using NFS as dynamic volume provisioner. Clusters will be running in the cloud and make use of dynamic provisioning that the cloud provider offers. NFS is not secure. There are OpenEBS, Rancher's Longhorn. When it comes to storage provisioning, there are lots of projects. I only covered the basics. If you were to take it seriously, then you will have multiple disk and some form of quota restrictions on the nfs server side. Because even if you create a PV of 1Gi, there is nothing stopping the pod from writing more than 1Gi data on that volume unless you have quotas setup on the nfs server side.
hi venkat...your explanation is awsome...I have a query...I have created a storage in cloud like amazon ebs or azure file disk or google cloud storge...can i use that storage in our on premise kubernetes cluster as dynamic volume
I can't remember but there is nothing that stops the pod from using more than it has claimed. I think I have tested it and noticed that the pod could indeed use more than requested.
fruitful as usual .. thanks! Now, I have a question, when I delete a pvc while the pv is still there, how to re-attach the pvc to the same pv again ?! trying to find any nfs solution providing this !
Hi, thanks for watching. What is the retain policy set to? There is Retain, Recycle, Delete. I guess yours is set to retain. It can't be reused for any other pvc. You can set it to recycle, in which case, the content of the pv will be deleted before it is bound to another pvc. If you want the content of previous pv to be available for some reason, then you can't use dynamic provisioning. You will have to manage the pv yourself. Cheers.
Just me and Opensource I’ve figured it out finally. However recycle is now deprecated, but using retain and specifying the volumeName solved it for me.
Such a nice explanation. Just a small question. When the 'archiveOnDelete: "true"' is set, the volume is prefixed with the archived on the deletion of PVC. So is this volume reusable or not since it is prefixed with archived?
Hi Yassine, thanks for watching. What you mean by mode? I used Archlinux with I3 tiling window manager in this video. For terminal, I used Alacritty terminal with ZSH shell and zsh-autosuggestions & zsh-syntax-highlighting plugin if thats what you were asking. Cheers.
I just use the GUI in Rancher to create a PV base on an NFS share on my NAS. Till now I was not able to connect that share to my workload. The moment I create a PVC base on that Persistent Volume and connect it to my workload, the workload stop working. You have any idea what this could be? What is the difference between your method and creating a PV or PVC in the GUI of Rancher?
Hi, Nice explanation and this works perfectly fine in most environments. Do you think this approach will work if I have setup a NFS server on a WSL Ubuntu image and then deploying a K8s cluster using K3d. Because in K3d we can not login into the nodes to install any packages. So I am trying to use a HELM chart nfs-client-provisioner to install client. But I am getting connection refused error in return, I have disabled the UFW also. Any comment on this scenario or what I should take care while using this.
Very nice video! However I have a problem installing it on my cluster: failed to provision volume with StorageClass "managed-nfs-storage" - permission denied I am sure that it has permission to write as I am able to mount the NFS share on my computer. Do you know any way to fix it?
