I'm having problems starting the cluster, I found this error during the node sync com.complexible.stardog.StardogException: Drop conflicts with other create operation.

Then I tried to repair the database and I found this error [WARN] 2019-11-21 07:41:25.732 [stardog-user-62] com.complexible.stardog.index.io.IndexIO - Index cannot be repaired, result was Index is not valid.  
Valid Indexes: []  
Invalid Indexes: [SPOC, POS, SPO, OSP, PSO, PSOC, OSPC, POSC]  
Repair Index: null  
Dictionary: Inconsistent  
Statistics: Valid  
The index cannot be repaired.

How can I fix this issue and make sure it doesn't happen again?

If I have to run cluster with one node, we will probably migrate to JENA and save money.

Thanks.  
PD. We have a cluster of 3 nodes in version 7.0.3 in GKC(google kubernetes cluster) and we do streaming updates on the data aprox(1000 writes a day).
