Off-Topic

Hi
My SingleStore cluster on a server(ip:192.168.5.20) with MA & Leaf.
Nodes address was configuration as follow:

  • For MA: 192.168.5.20:2707
  • For Leaf: 192.168.5.20:2708

On server existed the database and now some reason I have changed the server address to 192.168.4.20. After changed the IP address then CPU Usage, Memory Usage, Disk Usage was showing “UNKNOWN” and state on leaf was “Offline”.

How to re-config my cluster? Please advise me

Thanks so much
Cuong

Hi @cuong.nguyen. Where exactly are you seeing that? Are you using sdb-deploy and sdb-admin?

Here’s some documentation about changing an IP address:

I’m assuming you are SingleStore tools and not MemSQL ops, so these would be the correct instructions for you:

You should be able to get access to your data back if you follow those instructions. But it’s important to make sure you have a backup first. Since you can’t access your nodes, you may not be able to make a backup. To be conservative, you may want to copy the /data directories for all your nodes to something like /data_backup in case the process of changing the IPs fails somehow or your data otherwise gets damaged.
