es: 7.17.3 I mount the nfs path locally, and then point the es data directory to the location of the nfs, but the es startup fails, if I change the es data directory to a local partition (var/lib/elasticsearch) , then es can work. Does this mean that es doesn't support nfs as a data directory? ```auto mount -t nfs -o vers=3,nolock 10.0.0.1:/290e0e30-a7d1-4f79-a60d-d5c6870cf18a /mnt chown -R elasticsearch:elasticsearch /mnt/nfs ``` ```auto [2022-08-05T01:30:00,002][INFO][o.e.x.m.MlDailyMaintenanceService] [kaiqi-ubuntu] triggering scheduled [ML] maintenance tasks [2022-08-05T01:30:00,197][INFO][o.e.x.m.a.TransportDeleteExpiredDataAction] [kaiqi-ubuntu] Deleting expired data [2022-08-05T01:30:00,338][INFO][o.e.x.m.j.r.UnusedStatsRemover] [kaiqi-ubuntu] Successfully deleted [0] unused stats documents [2022-08-05T01:30:00,339][INFO][o.e.x.m.a.TransportDeleteExpiredDataAction] [kaiqi-ubuntu] Completed deletion of expired ML data [2022-08-05T01:30:00,340][INFO][o.e.x.m.MlDailyMaintenanceService] [kaiqi-ubuntu] Successfully completed [ML] maintenance task: triggerDeleteExpiredDataTask [2022-08-05T09:30:00,025][INFO][o.e.x.s.SnapshotRetentionTask] [kaiqi-ubuntu] starting SLM retention snapshot cleanup task [2022-08-05T09:30:00,027][INFO][o.e.x.s.SnapshotRetentionTask] [kaiqi-ubuntu] there are no repositories to fetch, SLM retention snapshot cleanup task complete [2022-08-05T10:26:51,661][INFO][o.e.n.Node] [kaiqi-ubuntu] stopping ...

The storage [must behave like local storage](https://www.elastic.co/guide/en/elasticsearch/reference/8.2/modules-node.html#data-path) so how you mount it will matter. Be aware that [networked storage can cause performance problems](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/tune-for-indexing-speed.html#_use_faster_hardware) as Elasticsearch can be very I/O intensive. ---

Thank you for your explanation. Leaving aside performance issues, the result is the same as what I thought. ES supports both local and remote storage. So, are there any restrictions on the underlying storage layer behind NFS? I remember that ES doesn't seem to support GlusterFS. ---

As long as it behaves like local storage and gives you the performance you want, Elasticsearch doesn't care. See [these docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#data-path) for more information. GlusterFS had some bugs that caused data corruption in the past (i.e. it did _not_ behave like a local filesystem) but as long as these bugs are all fixed then it should work. That said, IMO it's pointless to put a distributed system like Elasticsearch on top of a distributed filesystem, and it's still a bit of a risky choice (this filesystem is relatively new as filesystems go, and rather complex, and Elastic doesn't run any tests on it) but it's your data that's at risk so ultimately the choice is yours. ---

The error came from a NAS service in a public cloud, I just started a single node as a test, and then the above error appeared. If it is successful, I only plan to use only one NAS for one es node, and the cost will be lower. I have seen the results of NAS IOPS, and the performance is not very slow. ---

> [@wajika](#): > > I have seen the results of NAS IOPS, and the performance is not very slow. How was this measured? Often high IOPS numbers are achieved by performing large consecutive reads and/or writes. Note that this is not necessarily representative of Elasticsearch disk I/O patterns, so may be misleading. Elasticsearch does a fair bit of small reads and writes where latency is important. ---

The IOPS data is provided by the public cloud manufacturer. At first, I wanted to do a test myself, but using the NAS storage path caused the ES to fail to start. I contacted the public cloud manufacturer, and they reported that it is not recommended to use their NAS service as the ES storage. ---

I probably understand the result, so close the post for now. ---
