You know what I love about your videos? You get straight to the point with little to no bullshit along the way. So many times I have found tutorials online where the creator will talk about his life story before getting to the first step. Not you, sir. You get straight to the point so that everyone's time is not wasted. I really appreciate you and your expertise. I have to find your Patreon or whatever you use to take donations.

Just wow man! Thank you so much for those kind words 🙏 I'm so glad my video help you and I try my best to get to the point lol. Thanks, Glad to Help! www.patreon.com/GreyTech

It should be noted that if you create a cluster with only two nodes, if a single node goes down you will NOT be able to access your panel at all. Because of how the quorum system works, if half your nodes are down, the entire cluster stops working and goes read-only. For small home setups you probably DON'T want to cluster your nodes. Just keep multiple bookmarks in your browser.

@almaka17 4 месяца назад

I think its manageable as long as i make sure to frequently backup stuff and just be prepared that if one of the two stops working i would need to start from scratch

Does it matter on which device you create the cluster? I have a performant NUC and a cheap-o mini server. I want to know if the "main" server now needs more cpu/memory to manage the other nodes

@denirodarkqwerty Год назад

can i connect/manage a pimox cluster from a standard x86 proxmox datacenter interface?

@ricardofranco4114 6 месяцев назад

I have two proxmox servers. But each has different specs. Do they both need to the same internally to do this ?

@joshuagriffith6905 Год назад

Im trying to copy config files back, and am getting the error that the filesystem is full, is there a fix?

@ecotts 4 месяца назад

Does it matter if the spec is different between the clusters or is it better to keep them a similar spec?

@BrianThomas Год назад

So I did this. Is there a way to share resources in the VM in the cluster? Turning my quad CPU in the VM into an octacore CPU?

@gailsiebenaler7976 Месяц назад

Did you ever figure this out?

@BrianThomas Месяц назад

@@gailsiebenaler7976 No, I ended up moving away from Proxmox and started using CasaOS. It doesn't give me HA, but I'm a home user. I really don't need HA at the moment. However, I think I will install Proxmox on a different x86 mini PC and do some different things with LXC. Proxmox is starting to be like that girlfriend you just can't say no to. No matter how many times we break up I keep coming back

@not5477 Месяц назад

Is it possible to have multiple servers run a single VM with Proxmox? Like combining all their computing power into one system? As I see here, Proxmox cluster seems like it just combines the dashboards but the servers are still independent.

@aaronmathewson5522 6 месяцев назад

So in this example, clustering allows you to manage the other clusters from a “master” login… but not share resources with each other right?

Did everything to add a second node to my cluster but now getting - could not activate storage 'local-zfs', zfs error: cannot import 'rpool': no such pool available (500) Any advise?

I took out all the .conf files and now I cannot move them back because it says that the File already exists.... Now im screwed... HELP

@JazekFTW 8 месяцев назад

I had those .conf on the other server with other machines, so he couldnt move them as there was already those files in the other server... Weird as those are supposedly two different systems with their own files...

@ierosgr Год назад

At the part where you just deleted the .conf files of the Vms by cut-paste them via WinSCP, how come and you are sure the attributes of those files are carried away ? Usual this kind of copy requires special programs or parameters like robocoby. I believe that the attributes didn t passed to the other side (even though practically it seems Vms are working after the transfer again)

@user-yi8gm4nh5f 11 месяцев назад

Proxmox does not care about file attribute, it is safe to copy back config file.

How to create 2 clusters on the same proxmox server. So, 1 server with 2 clusters

@ZynthCode 2 месяца назад

Holy Batman, I almost lost 10 nodes! After doing this, you might lose the "local-lvm" storage configuration. Without it, all nodes that use it will break and won't start. Good news: the data isn't deleted, just the configuration is overwritten. To fix it, manually re-add the storage: Go to Datacenter -> Storage -> Add. Select "LVM" (if it was LVM type) and use the same ID, "local-lvm." Defaults should be fine, but make sure it's not shared. If you don't remember the storage name/ID, check the Tasks error log for something like "Error: storage 'local-lvm' does not exist.

@thunderslap7390 Год назад

All good then? The problem start when you want to remove a Node from a Cluster, be very careful how you setup nodes inside clusters, it can be your worst nightmare especially if you work on a Clients Infrastructure, you drop the ball in there you better know a quick exit like setting his Server room on "fire " by "accident" and then make sure the Fire Brigade wets those servers down properly so not a single one lives.

@capturedbyfabian 10 месяцев назад

‼️All these should come with a HUGE warning ⚠️ that explains that reverting it back and separating the cluster OFTEN goes wrong and is not a simple process. ⛔️

@rajivvishwa 7 месяцев назад

Can you explain the issues one would face while disconnecting the clusters? I was planning to setup a second proxmox node to get it to join to my prinary, but now want to be cautious

@capturedbyfabian 7 месяцев назад

@@rajivvishwa proxmox is not designed to de-cluster. I did it and was doing some testing and can’t recall why exactly had to remove the second machine from the cluster and found out that you have to manually change a lot of code in proxmox and force remove the other machine from the list because it will still show and a lot of other issues because even when you try to clean it all up there’s remaining code in the main one that cant be easily fixed at the end had to reformat the main server and re-install. Luckily I am running a Proxmox backup server as well and was able to restore all the vm machines and online services I am running like a ecommerce website etc. Proxmox Backup Server is the most important thing you can add to your proxmox server hands down!

@ImTheKaiser 6 месяцев назад

@@rajivvishwa renaming the host is no longer possible using the standard method of renaming /etc/hostname Deleting the old cluster is easy, but I sometimes run into issues where is still thinks it’s in a cluster. Lot of the config and management is now saved in /etc/pve/cluster And if you delete that, thinking it will reset the cluster config, you’re in for a hassle
