btw - if you remove the docker-compose changes, do the containers start normally?

thanks Stef, with max-size do you set it for every running service separately, or can you set it once?

thanks @<1523715084633772032:profile|AlertBlackbird30> this is really informative. Nothing seems to be particularly out of the ordinary though

3.7G	/var/lib/
3.7G	/var/lib/docker
3.0G	/var/lib/docker/overlay2

followed by a whole load of files that are a few hundred KBs in size, nothing huge though

so am I right in thinking it's just the mount points that are missing?based on the output of df above

Morning, we got to 100% used which is what triggered this investigation. When we initially looked at overlay2 it was using 8GB, so now seems to be acceptable.

Good point @<1523715084633772032:profile|AlertBlackbird30> 👍

yes those have all been created

so yes indeedly ..

sudo find /var/lib/ -type d -exec du -s -x -h {} \; | grep G | more

seems to give saner results.. of course, in your case, you may also want to grep M for megabyte

Howdy and Morning @<1687643893996195840:profile|RoundCat60> .. docker when using overlay2 doesn't have it's mount points show up in a 'df' btw, they will only appear in a 'df -a', mostly because since they are simply 'overlays', they don't (technically) consume any space (I mean, the files are still in the /var/lib but not for the space counting practices used by df)

this is why I was suggesting a find, maybe with a 'du' .. actually.. let me try that here.. 2s

Can you perhaps attach your docker-compose.yml file's contents?

It looks like not all the containers are up... Try sudo docker ps and see if the apiserver container is restarting...

In the publicly available AMI these are created. However, if you used a previously released Trains AMI and upgraded to ClearML, part of the upgrade process was to create those directories (required by the new docker-compose.yml ), as explained here: None

I think that if these directories are not mounted, you should first of all take care not to shut down the server. You'll probably want to exec /bin/bash into the mongo and elastic containers, and copy their data outside to the host storage

strange, I used one of the publicly available AMIs for ClearML (we did not upgrade from the Trains AMI as started fresh)

Not necessarily, is there any data in those directories?

not yet, going to try and fix it today.

if I do a df I see this, which is concerning:

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        3.9G     0  3.9G   0% /dev
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           3.9G  928K  3.9G   1% /run
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/nvme0n1p1   20G  7.9G   13G  40% /
tmpfs           790M     0  790M   0% /run/user/1000

so it looks like the mount points are not created. When do these get created? I thought using an AMI these would have already been setup?

Oh, that's strange. I'll run one of those soon to see if there's anything wrong with them

Hi @<1687643893996195840:profile|RoundCat60> ,
We've actually never had to address this issue. Can you find out what exactly is growing in size? I'd like to make sure this is not due to the containers storing data internally (causing docker to store more and more snapshots) - this is an unhealthy situation that might also indicate that volumes are not mounted correctly (i.e. data that should be stored externally is actually stored internally)

I added this to each of the containers

    logging:
      options:
	    max-file: 5
        max-size: 10m

... from the AMI creation script:

# prepare directories to store data
sudo mkdir -p /opt/clearml/data/elastic_7
sudo mkdir -p /opt/clearml/data/redis
sudo mkdir -p /opt/clearml/data/mongo/db
sudo mkdir -p /opt/clearml/data/mongo/configdb
sudo mkdir -p /opt/clearml/logs
sudo mkdir -p /opt/clearml/config
sudo mkdir -p /opt/clearml/data/fileserver
sudo chown -R 1000:1000 /opt/clearml/data/elastic_7

So it seems the AMI is using the correct directories... Do you have these?

@<1687643893996195840:profile|RoundCat60> can you verify all the volume mounts point to existing directories on the server machine? (i.e. /opt/clearml/... )

hey @<1687643893996195840:profile|RoundCat60> .. did you ever get the problem sorted ?

you will probably want to find the culprit, so a find should work wonders. I probably suspect elasticsearch first. It tends to go nuts 😕

no, they are still rebooting. i've looked in /opt/clearml/logs/apiserver.log no errors

also, is there a list anywhere with the mount points that are needed?

container_name:
  logging:
    options:
      max-size: 10m

incidentally we turn off the server every evening as it's not used overnight, we've not faced issues with it starting up in the morning or noticed any data loss

we turn off the server every evening...

In that case the issue is definitely not related to the mount points

yep, in most of them:

/opt/clearml/config
apiserver.conf
clearml.conf

/opt/clearml/data/elastic_7
/nodes

/opt/clearml/data/fileserver
<empty>

/opt/clearml/data/mongo/configdb
<empty>

/opt/clearml/data/mongo/db
collection/index files, /diagnostic.data, /journal etc

/opt/clearml/data/redis 
dump.rdb

/opt/clearml/logs
apiserver.log.x, filserver.log (0 bytes)

Try looking at their logs
