** [tickets:#2723] smf: Fix handling of MDS events in smfnd**
**Status:** fixed
**Milestone:** 5.18.01
**Created:** Fri Dec 01, 2017 02:05 PM UTC by elunlen

**Owner:** elunlen
The smf node direcor does not handle ACTIVE DOWN and UP events only service UP
and DOWN. This means that if a fail over of smfd happen and it takes a long
time (longer than MDS "Await Active Timer" timeout) for smfd to request a mds
role change the smfnd will timeout and get a service down event. When that
happen smfnd will reset the i_dest (set to 0) this means that smfnd no longer
can send any messages to smfd. Smfnd will restore i_dest if a service UP event
is received. However in this case this will not happen instead an ACTIVE UP
event will be received. Since smfnd does not subscribe to this event this will
go unnoticed and i_dest will never be restored. The smfnd has to be restarted.
