Issue/Introduction

In the below example, the dxgrid-db-size is set to 30000.  However, the system that the .zdb backup was taken from, the dxgrid-db-size was set to 2048.

Environment

Release : 12.x and 14.x

Component : CA Directory

Cause

This can occur when a Database (.db) or a backup of the database (.zdb) is copied from one node to another.  And the dxgrid-db-size on the new node wasn't configured to the same size of the node it was copied from.

Resolution

You will need to edit the DSA's .dxi file, in order to change the DataBase (DB) size.
- Go to $DXHOME/config/servers/  or  %DXHOME%\config\server
- Edit the .dxi for the DSA in question. 
- Replace the following the 'set dxgrid-db-size' with the DataStore (DB) mentioned in the warn log.
  In this example the warn logs detects the DataStore size to be 2048Mb.
- Make the following change to the dxgrid line:
set dxgrid-db-size = 2048;
As I mention above, you will need to set dxgrid-db-size to the size that's detect in the warn log.
- Then restart the DSA.
