Can the portworx "internal" kvdb coexist with etcd?

I have a tiny (three worker node, one controlplane) kubernetes cluster running and I want to configure portworx for storage. All my hosts are kvm virtual machines running Ubuntu 20.4.3 LTS with 5.4.0-73-generic kernel. I used https://central.portworx.com/specGen/wizard to generate a portworx 2.8.1.2-c9b840b (OCI) spec file and applied it to my cluster. I chose to not configure a dedicated kvdb drive on these hosts although each host does have a sdb intended as the portworx drive. (These sdb drives are not mounted.)

When I run pxctl status I see:

NODE NodeStartFailure 3a5bce08-b8ed-4fca-93a2-435a8d6e512b ALARM 1 Jan 9 18:31:45 UTC 2022 Jan 9 18:31:45 UTC 2022 > Could not find any available storage disks on this node. Node cannot act as a kvdb node as no storage device found. Waiting for other nodes to start kvdb. > If this is a storage node please add disks and restart Portworx.

Node cannot act as a kvdb node as no storage device found. Waiting for other nodes to start kvdb. If this is a storage node please add disks and restart Portworx.

I would rather use etcd instead of kvdb. Does anyone care to comment? Also, is the portworx operator intended for kubernetes?

oops. I just noticed this on the portworx website:

PX-Essentials support only built-in KVDB.
External ETCD is accessible in PX-Enterprise

Thanks.

Please post your edit as an answer, and accept it. This way the question won't stay unanswered.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
