Harsh J commented on HDFS-11422:
--------------------------------

IIRC, you can also use the command {{hdfs dfsadmin -restoreFailedStorage}} to control this.

> If a NN storage directory is removed due to an error, the NameNode will fail to write
the image even if the issue was intermittent. It would be good to have a way to make the NameNode
try writing again after the issue is fixed - and maybe even try it automatically every certain
amount of time (configurable).
