Subject: Swapping between fb and fb1 

Swapping between fb and fb1 as DAQ is very straightforward, now that they are both on the DAQ network:

  • stop daqd on fb
  • on fb sudoedit /diskless/root/etc/init.d/mx_stream and set: endpoint=fb1:0
  • start daqd on fb1.  The "new" daqd binary on fb1 is at: ~controls/rtbuild/trunk/build/mx-localtime/daqd

Once daqd starts, the front end mx_stream processes will be restarted by their monits, and be pointing to the new location.

Moving back is just reversing those steps.
