Oh.. You might be facing this - https://confluence.atlassian.com/jirakb/cannot-reindex-jira-due-to-expected-exactly-2-rows-the-maximum-marker-row-and-the-lowest-ranked-row-for-rank-field-779158916.html which requires more investigation. If the normal reindex is failing and you tried many times the best option is to read above KB and later contact support if you are not sure what might be the root cause affecting your instance.
