Hi all,
we've been running OpenVZ containers on numerous hosts in combination with DRBD for some time now, but run into an issue while trying to an auto-failover setup to work. When I (manually or from hearbeat) try to start a clean VE, the systems starts logging:
Message from syslogd@**** at Apr 18 17:01:01 ...
kernel:[ 1171.526494] unregister_netdevice: waiting for lo to become free. Usage count = 2
The message just keeps appearing and the VE never starts. I cannot even kill vzctl anymore. We haven't seen this in our other setups, can this be caused by heartbeat?
As long as I do not start the VE (onboot=no), heartbeat + drbd + openvz functions perfectly.
Some more info:
Linux ******** 2.6.26-2-openvz-amd64 #1 SMP Tue Jan 25 06:04:33 UTC 2011 x86_64 GNU/Linux
vzctl Version: 3.0.22-14
I'll paste my relevant config files below as well. If you need more info, please do ask.
Kind regards,
Richard van Looijen
