How to rebuild index ? - corrupt index for ArcGIS Portal 10.8.1

LarsRotnes

After using the reindex function in portaladmin, on the user index for ArcGIS Portal, we are stuck with a corrupted index.
The index is deleted and only users that re-logon to the portal are indexed. 
Problem is on a HA setup of ArcGIS Portal 10.8.1

I'm aware of the old howto "Manually rebuild the index in Portal for ArcGIS":
https://support.esri.com/en-us/knowledge-base/how-to-manually-rebuild-the-index-in-portal-for-arcgis-000020175

Is there now a way to achieve the same for 10.8.1?

Unfortunately, there is no way to manually rebuild the index in Portal for ArcGIS post 10.7.1. The article has the following note:

I would continuously run the reindex function in the Portal admin endpoint to see if that fixes it (several times if necessary). Otherwise, you may need to revert to a snapshot or webgisdr backup, if you have them.

You mentioned that your deployment is HA. I usually find it helpful to unregister the standby Portal when troubleshooting HA environments.
