Enquiry on Ceph setup

[uglyxiaodi]

Dear Team,


When I try to create Ceph Manager for my node 2, there is an error as below:
command '/bin/systemctl start ceph-mgr@chicago01' failed: exit code 1

When I try to create Ceph Monitor for my node 2, there is an error as below:
No active IP found for the requested ceph public network '68.235.48.139/29' on node 'chicago01' (500)

Where and how do I rectify the above error?

Thank you

What is your network setup? Ceph expects the network to be a private one that is available on all nodes.

I only have 1 ip address ( which can be used as public)
thus I have configure to use this ip address

Is there a way to edit the network ip address for this node 2? as I see from the GUI, there is no edit function for ceph ip address

How fast is the connection between the nodes? Because it sounds like a setup that will not make you happy when using Ceph. You should have at least a 10Gbit dedicated network in between the nodes with as little switches and routing as possible.
