Hi,
I met a problem with whitetank.
#ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
inet 127.0.0.2/8 brd 127.255.255.255 scope host secondary lo
inet6 ::1/128 scope host

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
qlen 1000
link/ether 00:1c:23:00:5a:8a brd ff:ff:ff:ff:ff:ff
inet 147.2.207.210/24 brd 147.2.207.255 scope global eth0
inet6 fe80::21c:23ff:fe00:5a8a/64 scope link
valid_lft forever preferred_lft forever
Note: There're multiple IPs on lo.
If I default all the timeout options in totem directive, everything goes all
right.
Though if setting "consensus" to a value greater than "downcheck", for example:
totem {
version: 2
secauth: off
threads: 0
consensus: 2500
interface {
ringnumber: 0
bindnetaddr: 147.2.207.0
mcastaddr: 226.94.1.1
mcastport: 5495
}
}
logging {
to_stderr: yes
to_file: yes
logfile: /tmp/ais
debug: on
timestamp: on
}
amf {
mode: disabled
}
And once I delete the listening IP:
# ip addr del 147.2.207.210/24 brd 147.2.207.255 dev eth0
Segmentation fault happens to aisexec:

There's the same problem when setting an alias IP on eth0 with a different
network address from "bindnetaddr"
So I patched clm.c to trace the problem:

Aug 31 18:29:15.406124 [CLM ] Cannot get interfaces for my_nodeid: 200007f
So the boudto.nodid became "127.0.0.2", but it could not be found from
my_memb_list.
..At last I found something in totemip.c: totemip_iface_check().
In the funtion, whether or not an appropriate interface can be found, the
"boundto" argument will be always updated in the end.
totemip.c:587:
totemip_copy (boundto, &ipaddr);
I applied a patch as the below:

It seems to reslove the problem. Otherwise there was any other consideration?
I haven't tried corosync + openais 1.0. No idea if it has the same issue.
Thanks,
