Introduce a storage.logs_volume config option #2484
Description
Is there an existing issue for this?
- There is no existing issue for this feature
What are you currently unable to do
Similar to the existing storage.backups_volume and storage.images_volume, this will allow moving what normally would be in /var/log/incus` over to a dedicated Incus-managed volume.
This is motivated by a recent stress test where after running over 7000 VMs on a server, our usage in /var/log/incus ended up filling the entire root disk. Nothing too bad, each VM was using just 3-4MB of storage, but that then would quickly add up.
Unlike what we do with backups and images, I don't expect us to move all data away from /var/log/incus and move it into the volume as that would interfere with /var/log/incus/incusd.log which is created prior to us setting up volume mounts.
Instead when the config key is set, we should relocate any instance folder from under /var/log/incus/ onto the newly created volume, then for any newly created instance log folder, we should do it under the configured volume, effectively only leaving /var/log/incus/incusd.log at the system path.
What do you think would need to be added
