Hi all,
I 've finished migration from 4.4.4 to 4.4.9 and I'm facing a strange
issue with routing table on my hosts: all IP addressed interfaces (and
in particular gluster and migration ones that requiere an IP) are not
part of the "254" or "0" usual ip rule.
for instance:
[root@fuego ~]# nmcli con sh gluster |grep ipv4.route-table
ipv4.route-table: 202179335
[root@fuego ~]# nmcli con sh migration |grep ipv4.route-table
ipv4.route-table: 316605387
but ovirtmgmt:
[root@fuego ~]# nmcli con sh ovirtmgmt |grep ipv4.route-table
ipv4.route-table: 254 (main)
and obviously the main route table is empty:
[root@ ~]# ip ro
default via 10.34.100.65 dev ovirtmgmt proto dhcp metric 425
10.34.100.0/24 dev ovirtmgmt proto kernel scope link src 10.34.100.116
metric 425
None of the concerned hosts can ping each other on such interface, and
live migrations systematically fail.
This behaviour is new with 4.4.9 and I don't know if it is a new (and
not achevied) network feature introduced with centos stream to deal
network filtering packets.
A simple workaround would be "nmcli connection mod migration
ipv4.route-table 0 && nmcli con up migration", but I'd like to
understand why such strange (and unuseful ?) rule table are now
randomly attributed?
