Issue

AltaVault system finds an inconsistent slab in the system. This causes the Data Integrity Alarm to be triggered.

Messages similar to the following might be displayed in the logs:
/alarm/state/alarm/data_integrity_error/display_name = Data Integrity Error (string)
/alarm/state/alarm/data_integrity_error/last_check_time = 2016/03/15 15:09:45 (datetime_sec)
/alarm/state/alarm/data_integrity_error/last_check_value = true (bool)
/alarm/state/alarm/data_integrity_error/last_clear_time = 2016/03/10 11:32:44 (datetime_sec)
/alarm/state/alarm/data_integrity_error/last_trigger_time = 2016/03/10 19:28:56 (datetime_sec)
