Search index host nodes removed after cluster restart



Configured search index host nodes are removed after cluster restart.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Deploy the application on  8 nodes, 4 of which are configured as search index host nodes on Search landing page
  2. Set the index file directory for each of those 4 nodes as /<somepath>/PegaSearchIndex
  3. Restart the nodes

Root Cause

The environment was not started in the correct order. The index nodes were not started first.


Perform the following local-change:
  1. Start the node identified as the master index node first
  2. Start the secondary index nodes followed by the non-indexing nodes

Alternatively, add the JVM arguement" " to prevent selection of non-indexing nodes:
  • Specify the directory to always make this node an index host node:<directory name>
  • Leave the setting blank to never make this node an index host node:
    Configure the setting on all non-index nodes.

If is not specified, and a custom index is used, the system uses the default directory if no other index host nodes are online when a server starts.
