Proxmox HA cluster - options for redundant storage?

[victorhooi]

Hi,

The plan is to have two servers in a Proxmox HA cluster, with a Raspberry Pi as the third node (https://pve.proxmox.com/wiki/Rasberry_pi_as_third_node)

Then we have a third machine running FreeNAS to provide VM storage (via iSCSI).

However, we still have a single point of failure in the storage.

What are our options to provide some kind of HA for the storage?

(I read about Ceph but it sees quite complicated, and we lose the nice features of ZFS like snapshotting and L2ARC etc.)

Regards,
Victor

i think you have to use a redundant storage like san with two dedicated controller.....
or you can configure a cluster ha with nas4free (carp + hast)....
but with your setup, freenas is a SPOF as you write....
and it can't be clustered .......
glusterfs can be an other option..

You could get rid of your RPI virtualizing your FreeNAS on the 3rd node (installing PM on it).
And you could create a 2nd FreeNAS VM (or whatever flavor of iSCSI target provider) on one of the 2 other node and use OS based software mirroring between 2 iSCSI LUNs to get rid of the storage SPOF.

You can also buy ZFS-HA machines to have your single point of failure in your storage removed.
