Hi, guys! After a long time without using it, I’m getting this error below when trying to do any operation (even trying to open the Node Activity section) on Dremio 1.1 EC2 using S3 as datastore:

I have 2 machines, 1 executor/master + 1 executor only.

```

Any ideas?

Hi @allan.sene,

Can you please send me the df -h output of both the servers? it looks like you are running out of space on one of your local file systems

Thanks  
@balaji.ramaswamy

Hi @balaji.ramaswamy,

I’d already check disk space on both servers. Seems to be ok. Look:

```
[ec2-user@dremio-master-01 ~]$ df -h
Sist. Arq. Tam. Usado Disp. Uso% Montado em
devtmpfs 15G 60K 15G 1% /dev
tmpfs 15G 0 15G 0% /dev/shm
/dev/xvda1 40G 2,2G 38G 6% /

```

```
[ec2-user@dremio-executor-01 ~]$ df -h
Sist. Arq. Tam. Usado Disp. Uso% Montado em
devtmpfs 15G 60K 15G 1% /dev
tmpfs 15G 0 15G 0% /dev/shm
/dev/xvda1 40G 2,2G 38G 6% /
```

That’s odd… just rebooted both machines and all come back to normal. lol 🤔 😂

Thanks anyway, Balaji!
