Hi,
ALL STATUS will only print status of DB nodes. Like this:
NDB> all status
Node 2: Started (Version 3.5.0)
Node 3: Started (Version 3.5.0)
Try the SHOW command instead and it will print something like this:
-- NDB Cluster -- Management Client --
Connecting to Management Server: 127.0.0.1:2200
NDB> show
Cluster Configuration
---------------------
2 NDB Node(s)
DB node: 2 (Version: 3.5.0)
DB node: 3 (Version: 3.5.0)
5 API Node(s)
API node: 4 (not connected)
API node: 5 (not connected)
API node: 6 (not connected)
API node: 7 (not connected)
API node: 8 (not connected)
1 MGM Node(s)
MGM node: 1 (Version: 3.5.0)
Notice that there is a difference if you type the commands in the MGM
Server(ndb_mgmd) window or if you use the Management Client(ndb_mgm).
I have used the Management Client in the examples above.
