Ceph » mgr » Dashboard

Description of problem¶

https://tracker.ceph.com/issues/50336 introduced a neat "Create Cluster" workflow, to help set up new clusters. When you first log in to the dashboard you're prompted to expand the cluster (or skip that step). IMO this screen should not be present at all, for clusters that have already been "expanded", for example if I've already used `ceph orch` to create OSDs, add hosts, etc. this step is redundant - I shouldn't have to click "skip", it should just not be there in the first place. Likewise if I'm upgrading from an earlier (pre-Pacific) release.

Environment¶

• ceph version string: 16.2.7-37-gb3be69440db
• Platform (OS/distro/release): SUSE Linux Enterprise Server 15 SP3
• Cluster details (nodes, monitors, OSDs): 4 nodes, 3 mons, 8 OSDs
• Did it happen on a stable environment or after a migration/upgrade?: seen after an upgrade from Octopus
• Browser used (e.g.: Version 86.0.4240.198 (Official Build) (64-bit)): Firefox 96.0.1 64 bit

How reproducible¶

Steps:

1. Deploy Octopus
2. Configure the cluster (add some hosts, OSDs etc.)
3. Upgrade to Pacific
4. Log in to the dashboard

or:

1. Deploy Pacific
2. Use `ceph orch` to add hosts, deploy OSDs, ...
3. Log in to the dashboard

Actual results¶

I see a screen that says "Welcome to Ceph Dashboard - Please expand your cluster first"

Expected results¶

I see the regular status screen

Additional info¶

Would it be enough to add a check to see if there's > 1 node and/or > 0 OSDs, and in this case assume we don't need to show this screen?
