Failed to allocate nodeid for mysqld

[Deepak Goel]

Hello

I created a NDB cluster of 4 data nodes, 1 management node, 3 server nodes. When I try to start my cluster, I get the following error:

----------------------------------------------------
2021-06-21 18:36:01 [MgmtSrvr] WARNING -- Failed to allocate nodeid for API at 172.31.63.143. Returned error: 'No free node id found for mysqld(API).' - Repeated 2 times

----------------------------------------------------

How can I resolve this?

Thanks!
