[Pacemaker] kvm VirtualDomain problem after reboot

[Arnold Krille]

Hi,

I went with running lsb:libvirt in the cluster too. That way you can define dependencies. And when corosync isn't started automatically (like when you do maintainance without switching init-levels) libvirt is stopped too.

Have fun,

Arnold

Ps: please excuse the phone-induced top-post.

Hi,

i have setup a 2-node cluster and configured 4 virtualdomain
resources using iscsi storage.

when i reboot one machine (shutdown -r now) everything seems
to be ok, virtual machines running on this node are migrated
away and continue to run on the other node.

but when the node comes up again i looks like it first checks
that none of the configured resources are running.

this checks fails VirtualDomain resources because libvirtd
is not running at this time, i can see a lot of errors like

Aug 17 15:30:06 pcmk1 lrmd: [1807]: info: RA output:
(p_virtdom_vm3:probe:stderr) Failed to connect socket to
'/var/run/libvirt/libvirt-sock': No such file or directory

the cluster does not startup does not succeed.
below you can see the cluster config.

what i am missing ?

thanks
ulrich
