> Currently, we store disks info in DB and this information is never updated after registration. As disks details can change (space availability changes, disks get mounted/unmounted, etc.) the persisted information is not useful.
> We should instead hold the details in memory and refresh it at certain intervals (e.g. once every 10 minutes) and then alert if space availability hits some lower limit.
