Howdy, netbooters everywhere. I am testing now with 5 clients (pcp3.20beta5) and a Raspbian Lite server. I'm trying to boot all 5 at once, with mixed results. Here is what I can report for now: - It looks like Pi 3 clients send discovery packets as soon as they have powered up, so if they are behind a switch that takes its time booting, like learning network topology for STP, then the packets are lost and the Pis stay put for a while. Don't know how long, it is not my test case. The solution seems to be configuring the switch to "fast-open" some ports to let the traffic go through. - My Pis wear Justboom amp HATs, for the moment I use two 24V PSUs, one 18V, one 12V and one 5V "official" Pi 3 PSU. I *think* that if the Pis are not totally powered down when they regain power, they don't boot so well. I have 1 of the Pis on nylon stand-offs, the 4 others on brass standoffs, no difference. The one with the "official PSU" is powered via µ-USB, the others via the DC barrel connector on the amp, no difference. - I am testing with 2 switches on the path: one giga integrated to a router, another next to the clients. For this one I test mainly with an old no-name fast switch: boot is not consistent, and sync sometimes suffers. I've also tested with a brand new Netgear GS108T v2: sync seems flawless, boot better but not perfect. - The setup I used initially (described above) was to automount a bind mount between /exports and /tftp. I found out the mounts would expire or not come up at the appropriate time, so I have replaced that with symbolic link. This clearly improved the boot success rate. - I *suspect* that the discovery protocol of LMS might cause some players to stall during boot. I have anecdotal evidence players boot better (if not perfect?) with LMS stopped. Supposedly broadcasts can stop a Pi from TFTP-booting, if you have more info on that I'm interested.
