Just for clarification, what Giacomo is refering to is this:
Hmmmmm,
Going through the steps in the KB, I would have done the epsilon and eligibility steps (Step 1 in the KB) right before the reboot (Step 8), *after* moving the aggregate and the LIFs away from the node to be worked on.
At that point in time it shouldn't disturb anything, since no user traffic should pass through this nodes interfaces or disks.
What do you think?
(I'm a little unclear about the meaning of "NFS was restarted", but I have a feeling the above change in sequence should help)
Also, if you look at the revert steps, the KB first restores eligibility and HA failover and only at the end reverts aggregates and LIFs.

Sebastian
