Harsh J commented on HDFS-11422:
--------------------------------
IIRC, you can also use the command {{hdfs dfsadmin -restoreFailedStorage}} to
control this.
> Need a method to refresh the list of NN StorageDirectories after removal
> ------------------------------------------------------------------------
>
> Key: HDFS-11422
> URL: https://issues.apache.org/jira/browse/HDFS-11422
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.6.0
> Reporter: Attila Bukor
>
> 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).
