Re: [xcat-user] "Failed to notify" during xCAT discovery of any node

Hi Chris,

Hmm, according to the following code in nodediscover.pm, you will not see "$node has been discoveryed" if you see "Failed to notify..." message.

#now, notify the node to continue life

my $sock = new IO::Socket::INET (

PeerAddr => $clientip,

PeerPort => '3001',

Timeout => '1',

Proto => 'tcp'

);

unless ($sock) { syslog("local4|err","Failed to notify $clientip that it's actually $node."); return; } #Give up if the node won't hear of it.

print $sock $restartstring;

close($sock);

# sleep 2 seconds for genesis to complete the disocvery process

sleep (2);

#Update the discoverydata table to indicate the successful discovery

xCAT::DiscoveryUtils->update_discovery_data($request);

syslog("local4|info","$node has been discovered");

Can you show the discoverydata table? (tabdump discoverydata). Is the mac defined for the node after the discovery?

Thanks,

Ling

xCAT 2.10 - when discovering any node on our system we always
see the equivalent of:

Aug 13 23:07:03 snowy-m xcat[23013]: xcatd: Processing discovery request from 10.14.3.3
Aug 13 23:07:06 snowy-m xcat[23013]: snowy001 has been discovered
Aug 13 23:07:06 snowy-m xcat[23013]: Failed to notify 10.14.3.3 that it's actually snowy001.
[...]
Aug 14 14:18:26 snowy-m xcat[18089]: xcatd: Processing discovery request from 10.14.3.99
Aug 14 14:18:29 snowy-m xcat[18089]: snowy-test has been discovered
Aug 14 14:18:29 snowy-m xcat[18089]: Failed to notify 10.14.3.99 that it's actually snowy-test.

Everything *seems* to work OK despite this so it seems to be
something cosmetic, but I'm just curious in case it's something
that we've missed in our configuration?

All the best,
Chris
