Storage

Implementation of the storage module interface

Mountpoints

Every volume which is managed by the storage module is mounted in /mnt. The name of the mountpoint is the label of the volume. For instance, a volume with label volumelabel will be mounted in /mnt/volumelabel. The volumes are mounted when the storage module is started, and remain mounted after that. In case the storae module exits in any way, there is no attempt to unmount any volume.

Since filesystems are created as subvolumes within the "root" volumes, they are always mounted.

Next to the volumes, the storage module also tries to instantiate a cache. It does this by creating a subvolume, preferably in a volume which was created on SSD devices, and then creates a bind mount in the /var directory. The full path of the cache is /var/path.
