Maintenance
Over time the cache database can grow in size due to version upgrades. To shrink the database to its minimum size, you can vacuum it. Multiple vacuums in a row have no effect as the vacuum itself rewrites the database from the ground up.
While the vacuum is in progress, it will take twice the database size and may take several minutes if you have lots of photos and a low-power system.
As an example it took around 5 minutes to vacuum a 260 MiB database containing around 500k photos on a DS418play. The size after vacuuming was 61 MiB as all the leftover data from database upgrades was cleaned up.
How to Vacuum
- Shut down the server
- Run the following commandsh
./photofield -vacuumshdocker exec -it photofield ./photofield -vacuum - Restart the server
