Manual cluster installation can't add leaf 6.8.10 on Redhat Linux 3.10.0-1062.el7.x86_64 x86_64

I am trying to create a cluster with one master aggregator and 4 leaf nodes
each VM 8 cpu and 32GB RAM assuming that is ok for free license
I have following nodes set up
±-----------±--------±--------------------------±-----±--------------±-------------±--------±---------------±-------------------±-------------+
| MemSQL ID | Role | Host | Port | Process State | Connectable? | Version | Recovery State | Availability Group | Bind Address |
±-----------±--------±--------------------------±-----±--------------±-------------±--------±---------------±-------------------±-------------+
| B7961A9093 | Master | memsqlaggregator.hq.local | 3306 | Running | True | 6.8.10 | Online | | 0.0.0.0 |
| 8C17A0E114 | Unknown | memsqlleaf1.hq.local | 3306 | Running | True | 6.8.10 | Online | | 0.0.0.0 |
| 31C9B5A5DB | Unknown | memsqlleaf2.hq.local | 3306 | Running | True | 6.8.10 | Online | | 0.0.0.0 |
| A6821F8549 | Unknown | memsqlleaf3.hq.local | 3306 | Running | True | 6.8.10 | Online | | 0.0.0.0 |
| 60A3EAC6C4 | Unknown | memsqlleaf4.hq.local | 3306 | Running | True | 6.8.10 | Online | | 0.0.0.0 |
±-----------±--------±--------------------------±-----±--------------±-------------±--------±---------------±-------------------±-------------+
But next steps which adding leaf Role to one of nodes it fails as below
[dxj001@memsqlaggregator software]$ memsql-admin add-leaf --memsql-id 8C17A0E11431225F81BCC6D049561A6429B51E13

dxj001@memsqlleaf1.hq.local’s password:

dxj001@memsqlleaf2.hq.local’s password:

dxj001@memsqlleaf3.hq.local’s password:

dxj001@memsqlleaf4.hq.local’s password:

Toolbox will perform the following actions on host memsqlaggregator.hq.local:

· Run ‘memsqlctl add-leaf --host memsqlleaf1.hq.local --port 3306 --user root’

Would you like to continue? [y/N]: y

✘ Failed to run ‘memsqlctl add-leaf’

Could not add leaf to cluster. Verify network connectivity between the node at memsqlleaf1.hq.local:3306 and the master aggregator.

Please ensure that you have entered the correct password for the node.

If the node does not yet exist, run ‘memsql-admin create-node’ and then retry this command.

I have verified ssh access across servers using ssh keys

Not sure what is wrong

I actually figured it out
I had to pass memsql password for add-leaf command like this

memsql-admin add-leaf --memsql-id 8C17A0E11431225F81BCC6D049561A6429B51E13 -p password

I think that’s what missing in the installation instructions

I also changed permission on memsql.cnf to 775

Thanks for the feedback. Glad you found a solution. I’ll have our documentation team review this part of the documentation.
