Not the ideal solution of course but it should work. However, on CentOS 7 the external harddisk is mounted under /run/media and the user. I copied the postgresql database directory and made sure it is owned recursively by postgres, changed the necessary settings in both the systemd unit and the conf file. I don’t believe that the volume will be mounted on boot in /run/media, that is for storage mounted by a user logged at the console. It would make more sense to set up a systemd .mount and .automount unit for the device and mount point (someplace outside of /run, such as /srv/mountpointname). Then set up the labels correctly. You need to use a file system that supports extended attribute if you want it to work with selinux, so XFS or ext4. -- Jonathan Billings
