Hi, how to deal with a shard in recovery_failed status？

[zhenyuan wei]

Hi all，
    I use solr-7.3.1 release，when split a shard1 to shard1_0&shard1_1，
encountered  OOM error，then shard1_0&shard1_1 publish a status as
 recovery_failed.
How to deal with a shard in recovery_failed status？
Remove shard1_0&shard1_1 and  then do split shard1 again?
Or any other way to retry?

Best wishes,
