How to configure UTMStack to store logs on an NFS share instead of the local machine?

[robyfr]

Hello,

​I'm looking for a way to configure UTMStack so that the logs received from various data sources are not stored on the local machine where UTMStack is installed, but on a NAS accessible via NFS.
​I understand that the logs are stored within a Docker container. What is the correct procedure to achieve this?
​Specifically, I would like to know:
​What is the specific path inside the UTMStack container where the logs are written?
​Should I mount the entire /var/lib/docker/ directory from my NAS, or is it sufficient to mount only a specific log directory?
​What is the recommended docker-compose.yml configuration to correctly map the NFS mount point to the container's log directory?
​Thank you for your help.

Update: I was thinking, maybe it would be enough to just mount the /utmstack directory? I know a lot of the data is stored in there, so maybe we can avoid moving the entire /var/lib/docker

Hello everyone,

​I'm writing to provide an update and to share the solution I implemented.
​After some local testing, I can confirm that mounting the /utmstack directory to a separate drive is the correct approach. I performed a test by moving the /utmstack folder to a new partition on a second local disk, and everything is working perfectly. The logs and all other UTMStack data are now correctly stored on the new partition.
​This confirms that the entire /var/lib/docker directory does not need to be moved. It's sufficient to manage only the /utmstack folder to offload the persistent data.
​Given that this process works for a local disk mount, it should also work in the same way for an NFS share, since both methods use the same fundamental Linux mounting mechanism.
