I'm using QIIME2 through Docker and ran into this problem.
It happens that the feature-classifier is not working when using the provided SILVA database.
However it works fine with Greengenes's. Any suggestions?
The error is down below..

Hi @lumluk!
Thanks for posting, and thank you for posting the full error trace. This is a problem with your system, not with the classifier itself. The key line is at the very bottom:
```auto
OSError: [Errno 28] No space left on device
```
So you are running out of disc space! This makes sense — the SILVA database is a good bit larger than greengenes, takes at least twice as much memory to run, and some of the temp outputs could also take up more disc space. So you are probably filling up your temp directory.
See here for details on diagnosing and fixing (try changing your temp dir most likely):

> Hi, I am a little confused as I have exactely the same issue then the last solved one previously (please see this link ([https://forum.qiime2.org/t/no-space-left-on-device-for-qiime-feature-classifier/2122](https://forum.qiime2.org/t/no-space-left-on-device-for-qiime-feature-classifier/2122) ) with the feature classifier. i changed the tmp directory with TEMPDIR=/some/directory but I still have have the same problème. Any suggestion on how you solved this problème will be appreciated Thanks

Hi @Nicholas_Bokulich, thank you for the reply.
I relocate the tmp folder of the docker to my local machine, which have plenty of space, but it still not working.
Now the error is gone, but it didn't produce any result (taxonomy) file either.
Somehow the program terminated without having the saving text - "Saved FeatureData[Taxonomy] to: taxonomy.qza" text after the command.
Any other suggestion?

--i-reads rep-seqs.qza \
--o-classification taxonomy.qza

Can you please re-run this variant of that command and provide any output? Thanks!
```bash
docker run -t -i \

-v /Users/tmp:/tmp \
qiime2/core:2018.6 \
qiime feature-classifier classify-sklearn \
--i-classifier silva-132-99-515-806-nb-classifier.qza \
--i-reads rep-seqs.qza \
--o-classification taxonomy.qza \
--verbose
```
Also, can you provide a little more info about your host environment? Windows 10? Mac? Docker toolbox? Something else?Thanks!

I've tried, no results either.
However, I natively install qiime2 and the command works fine.
Can it be docker's problem?

Ah, bummer.

Either that, or it is related to something on your host system. If you can answer the questions I asked above, that would help steer us in the right direction:

Ah ha! Okay, so let's circle back to your original problem:
> [@lumluk](#):
>
> OSError: [Errno 28] No space left on device
Setting a new tmp dir in your docker commands isn't going to fix that issue, and it might actually cause other problems. I think you need to actually configure the docker disk size, since out of the box it assumes pretty tiny virtual disk of
You should be able to boost that slider up to something more reasonable, assuming your host system has more available disk space to give!
So, make that tweak, then re-run your original command, without changing the temp dir. Let us know how it goes! :qiime2: 🦖

I already gave it 208GB.

Well, sounds like 208 GB still isn't enough, right? QIIME 2 isn't the only thing using this disk space (for example, in your screenshot it mentions that almost 70 GB are already in use from other docker containers and images).
