Help w/ install and setup

I have spread and wackamole running on two Whitebox Linux machines.

whelmon1 - 10.1.11.202
whelmon2 - 10.1.11.203

my router is 10.1.11.254

I want them to serve the vip 10.1.11.206/32. See the bottom of the
message for my configs.

When I start spread on whelmon1, I get this printed:
# /usr/local/sbin/spread -n whelmon1
Conf_init: using file: /usr/local/etc/spread.conf
Successfully configured Segment 0 [10.1.11.255:4803] with 2 procs:
whelmon1: 10.1.11.202
whelmon2: 10.1.11.203
[root[at]whelmon1 :/usr/local/sbin]$ Membership id is ( 167840714, 1100044395)
--------------------
Configuration at whelmon1 is:
Num Segments 1
1 10.1.11.255 4803
whelmon1 10.1.11.202
====================

When I start spread on whelmon2,
# /usr/local/sbin/spread -n whelmon2
I get the same thing pretty much printed, then after a second, the
following is printed on each machine:

++++++++++++++++++++++
Num of groups: 0

I then run wackamole on whelmon1, and it brings up the 10.1.11.206
interfac e (here is the log lines)

Nov 9 15:55:39 whelmon1 wackamole[3403]: connecting to 4803
Nov 9 15:55:39 whelmon1 wackamole[3403]: 934 No such interface
Nov 9 15:55:44 whelmon1 wackamole[3403]: UP:
eth0:1:10.1.11.206/255.255.255.255
Nov 9 15:55:44 whelmon1 wackamole[3403]: Re-queued arp spoof notifier
for virtual entry.

BUT - when I run wackamole on whelmon2, nothing happens, all I ever
get in the logs is:

Nov 9 15:56:24 whelmon2 wackamole[25450]: connecting to 4803
Nov 9 15:56:24 whelmon2 wackamole[25450]: 934 No such interface

I tried simulating a failure on whelmon1 and seeing if whelmon2 took
the IP (I thought maybe it was working, but was not very verbose about
it), and 10.1.11.206 disappeared, so no dice.

This is a whole lot of info to weed through, but I am trying to get
some suggestions on what I should do next to troubleshoot. It seems
like I am close, but something is missing such that whelmon2 doesn't
want to join in.

Thanks

Here is my spread.conf:

Spread_Segment 10.1.11.255:4803 {
whelmon1 10.1.11.202
whelmon2 10.1.11.203
}

And here is my wackamole.conf:

Spread = 4803
SpreadRetryInterval = 5s
Group = wack1
Control = /var/run/wack.it
Prefer None
VirtualInterfaces {
eth0:10.1.11.206/32
}
Notify {
eth0:10.1.1.254/32
arp-cache
}
balance {
AcquisitionsPerRound = all
interval = 4s
}

mature = 5s

Re: Help w/ install and setup [In reply to]

Well, to begin with, from the info you copied it looks like the Spread
daemons aren't finding one another, since the configuration that
whelmon1 installs is just whelmon1. Could you double check that they
*are* able to communicate, and that they do install a configuration
with both of them?

Cheers,
Ryan

What part of my config looked like it was only for whelmon1? I have
both whelmon1 and whelmon2 defined in my spread.confg

Here is the output from spmonitor run from whelmon1 as:
# spmonitor -n whelmon1

Re: Help w/ install and setup [In reply to]

Sorry, this part:

Configuration at whelmon1 is:
Num Segments 1
1 10.1.11.255 4803
whelmon1 10.1.11.202

I wasn't talking about the spread.conf config, but rather the
configuration installed by the daemons after they completed the daemon
membership algorithm.

However, your spmonitor output answered my question.

Cheers,
Ryan

Try using wackamole's "-d" option to turn on more debugging info.
Other than that, I'd be concerned about the "No such interface"
printout, but I'm not to familiar with that area of the code. Maybe
Theo has some advice.

Cheers,
Ryan

Re: Help w/ install and setup [In reply to]

I run it (wackamole -d) on machine 1, all works good, I then run it on machine 2

vwackamole: wackamole.c:702: Send_state_message: Assertion `ret ==
My.num_allocated' failed.
Aborted

That happens everytime I fire up the second wackamole instance on the
second machine (I can even switch order I launch them, and it will
happen on the other machine)

Re: Help w/ install and setup [In reply to]

On Nov. 1, someone else e-mailed with the same assertion failure.
Theo suggested to them that it may be a problem with configuration
files that differ between different Wackamole daemon instances -- they
should only differ, if at all, in the "prefer" clause. I can't do it
tonight, but I'll try to track down the meaning of that assertion this
weekend -- I would bet it's from the Wackamole daemon state exchange
in wackamole.c.

Cheers,
Ryan

Re: Help w/ install and setup [In reply to]

I looked further into this. I don't see that this should be related
to the configuration file, at least not in the most recent version of
the source code I have. The assertion "ret == My.num_allocated" is in
the function that builds state messages, for the Wackamole state
exchange. It's a basic sanity check -- the daemon packs one section
of the state message with each interface that is assigned to it,
according to the Old_table, the last consistent copy of the
Allocation_table. My.num_allocated should always be the same as the
number of interfaces that match this daemon. I don't see any bugs in
the way this variable is being changed, in my copy of the source code.
Do you know if it's maybe being overwritten somehow?

Cheers,
Ryan
