Hi,

Hope you are doing well.

Do you have this single MWG or multiple MWG's in CM cluster?

You can click on Show details on the error message you see and it will show you the UUID of MWG which is not letting save changes to happen.

Please take CLI acess of that node and check disk space usage using below command:-


df -h


Check the output of OPT partition utilization.



You can check which node has that UUID  from MWG GUI.


Take MWG GUI access->This can be checked under Configuration > select Appliances (Cluster) on the left side. Then, look at the Appliances Information section on the lower part of the main pane.  This shows the UUID (Universally Unique Identifier – unique per appliance), Name, Version & Current Storage Timestamp for all nodes in the cluster

Hi,

I am doing good.

So it is full OPT partition which is the culprit here as I thought.

Please refer below links in order to figure out what is consuming OPT partition here.
