Environment

VMWare NSX

Cause

Before the actual completion of resync for policy stream tag (triggered by running the command "start search resync policy") invoking resync of manager stream tag(by running the command "start search resync manager") will interrupted the resync of policy ("start search resync policy") that was triggered before. The NSX Manager UI will have issue where the inventory will not be display and the error "Cannot fetch system details: Re-creating indexes, this may take some time." will be seen.

Resolution

Issue is resolved in VCF 9.0
To prevent the issue from happening. Kindly make sure the resync or re-indexing is completed before running the resync/re-indexing for the other NSX components.
- Check the /var/log/search/search-manager.log log for below entries (Complete Indexing finished and Resync status is changed to 'value: "DONE"') for the start and the completion of the re-indexing before starting the resync/re-indexing of other NSX components.
  ReIndexing Started
  Complete Indexing Initiated for stream tags: search_policy
  Updated the resync status for node 2c######-####-####c-####-########30ea, stream tags search_policy and version 4.2.2.1.0.#######7 at 17#########70 to IN_PROGRESS
  Complete Indexing finished, took 3###5 ms
  Resync status is changed to 'value: "DONE"
  ' for value: "search_policy"
If the issue is already encountered. Kindly reboot the NSX Manager and check if the re-indexing/resync is completed for all the component using the above step 2 ("Complete Indexing finished" and Resync status is changed to 'value: "DONE"') if the re-indexing/resync is IN_PROGRESS for any of the component then kindly run the anyone of the below resync command to re-initiate the resync of that particular component.
start search resync policy
start search resync manager
start search resync all

Note: Above is example log snippets for the Indexing completion after running the resync command for Policy
