Mailing List Archive: [lvs-users] cannot bring interface up

I have been running lvs for few years now. It has been working perfectly.
since upgraded from 2.6.32-279.11.1.el6.x86_64
to 2.6.32-358.6.2.el6.x86_64 on real servers I could not bring the virutal
interfaces up.

I get the message :
host# ifup eth2:1
Error, some other host already uses address 192.168.1.1

I have these lines in /etc/sysctl.conf
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2

my distribution is RHEL6.4

does anyone having such issue ?

any help would be great

KH

Was the kernel really the only package that changed?

Is eth2 your 192.168.1.0/24 network? You probably don't want the VIP
there in the first place. The arp announce stuff only applies to traffic
for an IP on a different interface, not an alias/secondary IP.

If you move it to lo does it work?

Honestly, surprised it ever worked at all. Maybe the other 192.168.1.1
system wasn't up last time this system was rebooted?
