Continuous use of the disk in idle mode

[StoneEngineer]

MediaCMS is continuously using disks... no transcoding, no video playing, just idle run.
FYI: the arrangement is 2 mirrored nvme ssds serving as persistant volume for MediaCMS on Docker, thus two graphs.
Please advice.

What installation did you make, single server or Docker Compose? Are you sure there is no traffic on that time? Check the logs (tail -f logs/* for single server, or docker-compose logs -f for Docker Compose) at a time that there is no traffic, maybe there is something that runs (like a recuring task?)

Hi mgogoulos,
Thx for advice. This was docker swarm stack. However couldn't find anything suspicious in logs.
For now I created a dedicated VM for MediaCMS server and everything is working fine.
Will try docker swarm stack again in future.
