Search index host nodes removed after cluster restart

SA-65688

Summary



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.


Resolution

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

If -Dindex.directory 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.
