[DRBD-user] Some question about linstor

[yang zhenyu]

Hello,
I am a linstor newbie and very interested in it. I have installed
drbd, linstor-server, linstor-client. But I encountered some problems,
when I use it. And did not find the corresponding guidance document.
so I would like to ask you to help look.

My questions:
1. How to create a cluster of drbd.?
2. When I create a controller node, but it's state always is 'offline'. why?
3. Why some cmd return: 'This command is deprecated or not implemented', why?
4. Can you give me some guide doc about using linstor?

[root at node-1 ~]# linstor list-node

I use zfs:
[root at node-1 ~]# linstor list-resource
╭─────────────────────────────────────────────────╮

[root at node-1 ~]# linstor connect-resource test node-1

[root at node-1 ~]# linstor modify-resource test

[root at node-1 ~]# linstor list-volumes

The /dev/ directory has no any device. When I run the cmd in node-4:
[root at node-4 ~]# linstor list-node
╭───────────────────────────────╮

How to connect node-1 and node-4?
