Re: [Testbed-admins] Nodes Stuck in reloading



Here is what I found on the control network switch for vlan3

IGMP snooping is globally enabled
IGMP snooping is enabled on this interface
IGMP snooping fast-leave (for v2) is disabled and queried is disabled
IGMP snooping explicit-tracking is enabled
IGMP snooping last member query response interval is 1000 ms
IGMP snooping report-suppression is enabled

It looks like frisbee is not starting up for you.

Let's try the easy thing first.  It is possible that the DB has leftover
state that prevents a frisbee server from starting.  First see if you
have
a frisbeed running on your boss for the image in question
(CENTOS53-64-STD
or whatever).  If not, go into the web interface and goto the info for
that image: Experimentation -> List ImageIDs -> <select your image>.
It should show the "Load Address" and "Frisbee pid" as blank.  If those
are
set, then the system thinks there is a server running for that image
when
it really isn't.  You can edit the image descriptor and clear the load
address and set the pid to 0.

If that is not the problem, then you probably have a multicast issue.
Did your control net switch lose power in the outage?  You may need to
go
in and make sure IGMP snooping is enabled.
