I have a similar setup, the seafile server application and nginx are located on the SSD, the seafile data is on two harddisks in a RAID setup.
However, as long as seafile clients are connected to the server, the disks keep spinning.
So they only shut down during night hours, when all three clients are disconnected.
I wonder if this can be changed?
Because the harddisk keeps spinning even if there is no file activity, the connected client itself keeps the disks running.
Does anyone know if it is possible to move the seafile database to the SSD as well, and keep only the data itself on the HDD? but also to keep a copy of the database on the HDD, when files are changed?
