Hi guys.

OK I'm having an unusul problem with Elasticsearch. Where it's reporting a low disk condition on one of the nodes. And it keeps reporting low disk conditions even after I've cleared out enough disk space by deleting / gzipping old log files. And it continues to do so even after restarting the elastic search service on all nodes.

Here's the complaint in the logs:

```
[2015-07-16 16:50:20,402][INFO][cluster.routing.allocation.decider] [JF_ES1] low disk watermark [85%] exceeded on [TswNkBU1QE2_Q_ZAR_Lprg][JF_ES2] free: 2.4gb[12.4%], replicas will not be assigned to this node

```

I've installed and setup Marvel. And it's reporting the exact same thing! 2.4GB free of disk space on node 2.

But when I take a look at the real conditions on the disk with the df command, I see a different story on that node:

```
[root@es2:~] #df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 17G 3.1G 85% /
devtmpfs 742M 0 742M 0% /dev
tmpfs 750M 0 750M 0% /dev/shm
tmpfs 750M 81M 669M 11% /run
tmpfs 750M 0 750M 0% /sys/fs/cgroup
nfs1.example.com:/var/nfs/home 20G 12G 6.9G 64% /home

```

So what's going on with that log message and the message in the marvel kibana interface? How do I correct this?

Thanks,

---

Where do you have your Elasticsearch data? The log message shows:

> [@bluethundr](#):
>
> low disk watermark [85%] exceeded

And df -h shows at ~85% for /:

> [@bluethundr](#):
>
> /dev/vda1 20G 17G 3.1G 85% /

You should try to reduce it below 85% and still see it reports the same.
