Proxmox Virtual Environment Complete Course Part 16 - High Availability

In the final episode of LearnLinuxTV's Proxmox VE tutorial series, we explore the concept of high availability. This will ensure that our most important virtual machines are always running, even if one of the nodes in our cluster stops responding.

Thanks for the great series! Just a note on the "did not loose a ping". If you check again at time 12:26, you will see that seq numbers 86-88 are missing. So 3 pings lost :)

It's worth talking about creating groups for HA as well. By assigning your VM to a group, you can add more control to it's HA behavior - You can restrict nodes for migration, prioritize nodes for migration, and control how fast machines will migrate back to the original node when the downed server comes back online.

Absolutely Brilliant Course! - For FREE!!! - Saved thousands of dollars and have implemented 5 nodes with full HA - Finally kicked VMware into touch!

Thank you for pumping these out this week. Thanks Jay!!

I spent most of my day with this course series and have learned so much, had a lot of fun with my home lab and this is just the start. Thank you so much.

[shadynit]

The watching your Video is like addiction. Very smooth learning and I miss your upcoming videos. Thanks again from my heart. I learn a lot from you specially you have explained the enterprise things and production environment.

[lespinoz]

I really enjoyed all chapters, was able to follow along and was able to implement my home lab!
Thank you very much!
This is something I will for sure recommend!

[demandelz]

Thank you for your series on Proxmox. I have been migrating my personal vm's to a homemade, baling-wire Proxmox cluster and found your video series on Proxmox very useful. I want to add that I like your work and often recommend your videos in community college classes I teach.

[atomboy]

Thank you for this great full course, Jay! I learnt a lot with the videos and I will try to rethink the structure of my servers at my workplace.

[hazoumsoussi]

Thanks, i'm a cloud system engineer architect and this is really usefull

[shadynit]

You are awesome man. The way your explanation is superb awesome. I learn with you and its really a nice fun with you. Feels like this is live class instead of video.
So much thanks to you.

Enjoyed the series Jay, thank you. This was my first dip at learning the use of ProxMox. Don't think I could have started anywhere better.

Would love to see a bit more detail on VLANs and assigning them to a single port. Great work

Thanks for this video. I managed to get HA setup with the single NVME installed in each node -- no other drives. When I installed Proxmox, I set it the small 512GB NVME as a ZFS RAID 0 (but single drive RAID 0). Then after say creating a container, I set it up to replicate to the ZFS pools (rpool) on the other 2 nodes.. I set the replication frequency to be like every 5 minutes during this experiment. I went to HA and added the container to HA. Unplugged the node it was on (after it had replicated already) and sure enough the HA started up the CT ID on another node using the replicated copy :) So you can do HA with ZFS Replication. (It takes a snapshot and sends teh snapshot differences to the other host when replicating.. it's pretty fast).

[tokoiaoben]

Thank you very much Jay. Finally I finished the whole series. I will definitely come back and watch the series when I have 3 servers to setup clusters and HA. Also a special request if you can do full series on SAMBA active directory on Ubuntu. Anyway thanks again.

[balloth]

At 12:25, you say it didn't lost any ping but it did, the loss is almost silent but we can see the sequence number going from 85 to 89, so 3 pings (which is not a lot) have been lost

[caasberg]

I love your videos. Great work!
Membership added. 😀

[eyesbj]

I really appreciate this course. Very easy to understand. Thanks.

[RP-rsky]

Thank you Jay. Appreciate your work. Keep the good work 👏 going.

[aqeelabbas]

thank you so much for this curse, it helped a lot now I'm able to setup a high end web-server using Proxmox. Great Job !
