Well, that was a bad idea. Rebooted our NAS, forgetting that I had the update waiting to install
LAGG is down and does not work
[Follow up]
Ok, after accidentally bringing our company to a screeching halt today for 45 minutes, I stumbled across the "
FAQ: Upgrading from 9.3 to 9.10", which states:
Q: I upgraded to 9.10 and my LACP (lagg) interface stopped working. It worked great in 9.3! HELP!
A: LACP links actually only "sort of" worked in FreeBSD 9 - they would misbehave in odd and difficult to diagnose ways when one of the physical links failed. In FreeBSD 10 (and hence 9.10), Active LACP is now enforced so that there is a proper heartbeat and the robustness of the link can be assured. Re-configure your switch for Active LACP and your lagg will work again.
Switching from "static LACP" to "active LACP" on our Netgear XS728T 10GbE switch, everything works. In fact, LAGG(w/ kernel tweaks 45 Drives sent me) far more stable and we are getting read/write speeds approx 100-200 MB/s faster(740MB/s-940MB/s) to all clients on the network with streaming video.
