Can someone point me in the right direction please? I cannot find any help on this, basically I am new to fog and Linux, I have been tasked with deploying fog, we have 4 sites all on extremely slow links so would like to have the main fog server at head office and a storage node at each site, when a client pxe boots it needs to look at the database at head office for task assignments but pull the images from its local storage node, is there a numpty’s guide to acheive this please?
