It looks like I still have (at least) two things to do -- make them
allocatable and associate their ports with switch ports. I poked around
in the database, but I couldn't see why they're not allocatable.
I poked around myself, and a bunch of the entries for at least netfpga3 in the
nodes table were NULL, including some significant ones. I think I fixed up
netfpga3 by doing the following query (you'll want to repeat for the rest)
*and* adding an entry into node_status for it (i.e.,
"insert into node_status values ('netfpga3','up',NULL)"):
update nodes set inception=now(),def_boot_path='',def_boot_cmd_line='',next_boot_path='',pxe_boot_path='',rpms='',deltas='',tarballs='',startupcmd='',startstatus='none',bootstatus='unknown',status='',status_timestamp='',failureaction='fatal',eventstate='ISUP',state_timestamp=now(),op_mode='MINIMAL',op_mode_timestamp=now(),allocstate='FREE_DIRTY',allocstate_timestamp=now(),next_op_mode='',ipodhash='',osid=181 where node_id='netfpga3';
I'm not sure how these fields got to be the way they are (perhaps you used the
defaults?)... but you need more than one of them (not sure of the complete set)
set to not NULL to even be able to use sched_reserve/nfree to get them in an
allocable state. Sorry if that wasn't clear...
