Fresh MinIO install on K8s with Helm: "unable to use the drive, drive not found"

First of all... Using NFS shares with MinIO is strongly discouraged. It's preferred to use DirectPV to connect to local disks.
Second... It look like you are using two nodes with a single disk, which is an unsupported scenario (for production) as well.

Manually creating persistent volumes is not a scenario where MinIO operator was designed for. Why are you creating your own persistent volumes? MinIO just expects an empty directory when you attach a persistent-volume. You may want to shell into the MinIO container and see what's actually is mounted under /export/data.

If the problem is that nodes can see their own disk, but cannot see the other instance, then shell into the pod and try to curl the other node. If it doesn't work, it's a networking issue.

You may want to try to create a tenant the "normal" way. Make sure it works and check the differences...

I have done this in the past by manually creating the PVs, which then bound to the PVCs, and everything worked fine. However, as Ramon mentioned, this is a manual process we should avoid because it is time-consuming and prone to errors.

This is precisely why we introduced DirectPV—to address the challenge of providing persistent volumes efficiently.

Now, regarding your error: drive not found. When this error occurs, it could also be due to a network issue. If that’s the case, it is unrelated to the manual process described earlier. I’m not certain what specific firewalld rule might block the traffic, but I suggest trying an alternative approach. Rather than modifying the firewall rules, please use DirectPV and check if the issue persists.

Additionally, run this command:

mc admin info myminio

This will help determine if only some disks are offline or if all of them are. In cases of network issues, it’s common to see some disks offline while others remain online. This could provide valuable clues to identify the root of the problem.
