>
> When a storage directory is inaccessible, namenode removes it from the valid
> storage dir list to a removedStorageDirs list. Those storage directories will
> not be restored when they become healthy again.
> The proposed solution is to restore the previous failed directories at the
> beginning of checkpointing, say, rollEdits, by copying necessary metadata
> files from healthy directory to unhealthy ones. In this way, whenever a
> failed storage directory is recovered by the administrator, he/she can
> immediately force a checkpointing to restored a failed directory.
> See also HADOOP-4885.
