+The single host install stores user data in a PostgreSQL database (usually found under @/var/lib/postgresql@) and as Keep blocks that are stored as files under @/var/lib/arvados/@.
+Arvados logs are also kept in @/var/log@ and @/var/www/arvados-api/shared/log@. Accordingly, you should ensure that the disk partition containing @/var@ has adequate storage for your planned usage. We suggest starting with 50GiB of free space.
