Jumbo frames again
Wed Feb 3 11:27:19 PST 2010

Arghh...I just spent 24 hours trying to figure out why shadow migration was causing our new 7310 to hang. The answer? Because jumbo frames were not enabled on the switch the 7310 was on, and they were on the machine we're migrating from. Arghh, I say!

ShadowAnnoyance

Wait until you try to use shadow migration against a Linux box that lists NFS4 as available (via portmap), but isn't actually running the daemons. You'll get a hung interface while it retries....for something like 10,000 hours (no joke).
