Question About Cluster?

[killmasta93]

Hi,
I was wondering if someone could clear up a question i have about clusters. Currency have one proxmox box with 32gigs of ram with ZFS raid 10, with 16tb (8tb total). To have a cluster do i need another box with the same RAM and amount of TB? And does the cluster also replicate the containers or only the vms?

Thankyou

no

And does the cluster also replicate the containers or only the vms?

The cluster does not replicate VM/CT data (only configuration data). You need shared or replicated storage to achieve that.

Thanks for the reply, so the cluster is just to have the same config on both boxes but no vms or containers are replicated. But proxmox does have an option to have replicated storage?

it's a bit more than that ..

but no vms or containers are replicated.

yes, image data is not replicated magically.

But proxmox does have an option to have replicated storage?

We support many options for replicated storage: ceph, gluster, async zfs replication, ...

And you can also use any kind of shared storage.

Thanks for the reply, as from your experince out of those 3 which would you recommend for zfs? I was reading on ceph seems really good but not sure about the others?
