New to Proxmox - Issues with ZFS & local-lvm

[Redders]

Hello Forum,

I have recently started to experiment with VM's and Proxmox.

I set up my first node on an old gaming system. I had 3 different drives (1 x 240gb SSD, 1 x 2tb HDD and 1 x 1tb HDD) and I managed to set up multiple VM's perfectly fine).

I began to investigate what Proxmox could do and was really interested in having multiple nodes in a cluster. I had plently of old hardware hanging around and was donated another old machine. On the 2nd node, I had 4 HDD, 2 x 500gb and 2 x 1tb. On the 3rd, with the remaining pieces, I had a 300gb HDD and 1 tb.
I know that there is probably a better configuration for all of this but really just trying to experiment with the functionality.

When I was installing PVE on the 2nd node, I set it up with ZFS (I think ZFS1) on the 500gb HDD's. Where as, as I didn't have any matching sized drives on the other systems so just chose the fastest drive on each.

The issue that I've encountered is with the local-lvm on the 2nd node, it shows a question mark next to local-lvm and if I select that then VM disks, it says "no such logical volume pve/data (500).

I don't know what I'm supposed to do to make this right?

there is not local-lvm storage in zfs install of proxmox ve.
it should be local-zfs.
local-lvm is for ext4 pve os install where lvmthin is used to store VM'vDisks.

Thanks for your reply @_gabriel,

What I don't understand is why it has added it to my node if there was only zfs install of Proxmox VE on that node. Is it because I did an Ext4 PVE install on my first node?

Also, should it be showing local-zfs instead? or do I need to add this manually? It currently shows local and local-lvm (with a question mark)

I think I've got it, please let me know if this is wrong.

I have gone into Storage on the Datacenter and selected the local-lvm. I selected the 2 other nodes (putting a restriction on node 2). I then added storage of ZFS, selecting the ZFS pool on node 2 and gave it an ID.

Does that sound about right? Is there anything that I should be considering with this?

 

[_gabriel]

yes,
keep in mind the storage configuration is common/shared over the cluster, but "local-xxx" storage of each node cannot be used by the other, it remains local to the node itself, irrc (no yet cluster project here).

Thanks again @_gabriel.

Please bear with me as I try to understand this better. If I aim to set up High Availability within the Proxmox cluster, is it accurate to say that I would need to configure shared storage? Is this what you mean when you say no yet cluster project here? or is there something else that I'm missing?

 

[_gabriel]

no cluster yet project is my situation...
it seems you want ~HA thanks zfs replication ?
I haven't tried myself, doc is here :

Ahh, ok. Fair enough, everyone is on a journey

I do want to do HA but I'm a bit off getting it there and I think I need to reconfigure the drives that I have and I have more on their way so wish me luck
