+# Directory Configurations for Datanode
-**TODO:** File a subtask under
[HDDS-9859](https://issues.apache.org/jira/browse/HDDS-9859) and complete this
page or section.
+This section describes directory-related configuration properties used by
Datanodes.
+
+| Property Name | Description
| Tags | Default/Example
Value | Sample Value |
+| ---------------------------------------- |
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| ---------------------------------------------- |
---------------------------------------------- |
------------------------------- |
+| `hdds.datanode.dir` | Local filesystem directories
where HDDS stores data (container block files). Use comma-separated paths; tag
each with a storage type (`[DISK]`, `[SSD]`, `[ARCHIVE]`, or `[RAM_DISK]`) for
storage policies. | OZONE, CONTAINER, STORAGE, MANAGEMENT | Empty
| `/data/hdds/disk1` |
+| `hdds.datanode.data.dir.permissions` | Permissions for Datanode **data**
directories (octal or symbolic).
| | `700`
| `700` |
+| `hdds.datanode.container.db.dir` | Base location for per-disk
RocksDB instances that hold container metadata. If unset, RocksDB is placed on
the same disk as the matching HDDS data. Prefer fast storage (for example SSD).
| OZONE, CONTAINER, STORAGE, MANAGEMENT | Empty
| `/data/hdds/rocksdb` |
+| `hdds.container.ratis.datanode.storage.dir` | Directory for Datanode Ratis
metadata (for example closed-container replication logs). If unset, falls back
to default metadata dirs and a warning is logged. Use fast, durable storage.
| OZONE, CONTAINER, STORAGE, MANAGEMENT, RATIS | Empty (uses
default metadata dirs) | `/var/data/ozone/dn/ratis` |
+| `ozone.scm.datanode.id.dir` | Filesystem path where the
Datanode stores its persistent **Datanode ID** file. If unset, the ID is
created under the metadata directory.
| OZONE, MANAGEMENT |
Empty | `/var/lib/ozone/datanode-id`
|
+| `ozone.metadata.dirs` | Fallback metadata root for
Datanodes (and SCM, OM, Recon) when component-specific directories are not set.
Fine for test/PoC; production should set explicit paths such as
`hdds.container.ratis.datanode.storage.dir`. | OZONE, OM, SCM, CONTAINER,
STORAGE, REQUIRED | Empty |
`/data/ozone/metadata` |
