[ovirt-users] dwhd error: host_interface_samples_history_pkey

Ovirt events keeps saying "ETL service sampling has encountered an error. Please consult the service log for more details." ovirt-engine-dwhd.log says: 2016-05-27 10:55:00|UWxd1W|48u96S|MjrqV0|OVIRT_ENGINE_DWH|StatisticsSync|Default|6|Java Exception|tJDBCOutput_4|org.postgresql.util.PSQLException:ERROR: root page 3 of index "host_interface_samples_history_pkey" has level 0, expected 1|1 Exception in component tJDBCOutput_3 org.postgresql.util.PSQLException: ERROR: current transaction is aborted, commands ignored until end of transaction block at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2157) (see attached) I double checked all my VMs, they all have an interface assigned. Not sure what host_interface_samples_history_pkey is referring to. Thanks.
