Hi, We've started implementing a Glusterfs-based solution for instance storage in order to provide live migration. I've run into a strange problem when using a multi-node Gluster setup that I hope someone has a suggestion to resolve.
I have a 12 node distributed/replicated Gluster cluster. I can mount it to my client machines, and it seems to be working alright. When I launch instances, the nova-compute log on the client machines are giving me two error messages: First is a qemu-kvm error: could not open disk image /exports/instances/instances/instance-00000242/disk: Invalid argument (full output at http://pastebin.com/i8vzWegJ) The second error message comes a short time later ending with nova.openstack.common.rpc.amqp Invalid: Instance has already been created (full output at http://pastebin.com/6Ta4kkBN) This happens reliably with the multi-Gluster-node setup. Oddly, after creating a test Gluster volume composed of a single brick and single node, everything works fine. Does anyone have any suggestions? thanks, JP _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
