Details

    Description

      Build : 7.1.0-1567
      Test : -test tests/2i/cheshirecat/test_idx_clusterops_cheshire_cat_recovery.yml -scope tests/2i/cheshirecat/scope_idx_cheshire_cat_dgm.yml (With OSO enabled)
      Scale : 2
      Iteration : 1st

      Started to see a negative value for the num_rec_compressible plasma stat since 2021-10-26T00:27:32 on 172.23.97.216. This is also seen across all the other index nodes throughout the test.

      For 172.23.97.216, in the attached logs, 

      "Index": "bucket3:scope_2:coll_18:idx1_8KbU7aE", "Id": 15038446144302003408, "PartitionId": 0,
      		 
      "Stats":
      		 
      {
      		 
      "BackStore":
      		 
      {
      		 
      "num_rec_compressible": -221463,
      		 
      }
      		 
      }

      Other index nodes : 172.23.107.2, 172.23.107.3, 172.23.107.5, 172.23.97.217

      This issue was not seen in the previous runs. But in this run, I have also enabled OSO for GSI on Deep's request - not sure if this is because of OSO.
