> Detect slow disks separately by storage type
> --------------------------------------------
>
> Key: HDFS-17936
> URL: https://issues.apache.org/jira/browse/HDFS-17936
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.6.0
> Reporter: caozhiqiang
> Assignee: caozhiqiang
> Priority: Major
> Labels: pull-request-available
>
> The current slow disk detection does not differentiate between storage types.
> When a DataNode has 1 SSD and 10 HDDs with
> dfs.datanode.max.slowdisks.to.exclude=2 and
> dfs.datanode.min.outlier.detection.disks=5, if the SSD is under heavy
> read/write load, the single SSD may be identified as a slow disk. Client
> tasks writing SSD data to that DataNode will then fail to select a volume and
> report: No more available volumes.
> {code:java}
> public V chooseVolume(List<V> volumes, long replicaSize, String storageId)
> throws IOException {
> if (volumes.size() < 1) {
> throw new DiskOutOfSpaceException("No more available volumes");
> }
> ...
> } {code}
> Therefore, slow disk detection should be performed separately for each
> storage type. If the number of disks of a given storage type is less than
> dfs.datanode.min.outlier.detection.disks, detection for that storage type is
> skipped entirely.
