 Alternative database can also be configured (e.g. leveldb, postgres) following the instructions at `filer.extraEnvironmentVars`.
 
+#### RocksDB variant
+
+The `_large_disk_rocksdb` image tag ships with RocksDB pre-configured as the filer backend.
+To use this image with the Helm chart, override the image on all three components and disable
+the chart's default `WEED_LEVELDB2_ENABLED`, which would otherwise re-enable LevelDB2 and
+override the image's built-in RocksDB configuration:
+
+```yaml
+# Replace <VERSION> with the desired seaweedfs version, e.g. 3.80_large_disk_rocksdb.
+master:
+  imageOverride: chrislusf/seaweedfs:<VERSION>_large_disk_rocksdb
+
+volume:
+  imageOverride: chrislusf/seaweedfs:<VERSION>_large_disk_rocksdb
+
+filer:
+  enablePVC: true
+  imageOverride: chrislusf/seaweedfs:<VERSION>_large_disk_rocksdb
+  extraEnvironmentVars:
+    WEED_LEVELDB2_ENABLED: "false"
+```
+
+Notes:
+
+* `master` and `volume` use the same image tag so that all components share a consistent
+  SeaweedFS build; RocksDB itself is only used by the filer.
+* `filer.enablePVC: true` (or another form of persistent storage for the filer) is required
+  so that the RocksDB metadata store survives pod restarts — otherwise metadata will be lost.

 ### Node Labels
 Kubernetes nodes can have labels which help to define which node(Host) will run which pod:
