It's all working now. Cheers, Alessandro Il 30/05/16 10:55, Alessandro De Salvo ha scritto:
Hi, I'm happily using our research cluster in Italy via gluster, and now I'm trying to hotplug a ceph disk on a VM of my cluster, without success. The ceph cluster is managed via openstack cinder and I can create correctly the disk via ovirt (3.6.6.2-1 on CentOS 7.2). The problem comes when trying to hotplug, or start a machine with the given disk attached. In the vdsm log of the host where the VM is running or starting I see the following error:
jsonrpc.Executor/5::INFO::2016-05-30 10:35:29,197::vm::2729::virt.vm::(hotplugDisk) vmId=`c189472e-25d2-4df1-b089-590009856dd3`::Hotplug disk xml: <disk address="" device="disk" snapshot="no" type="network"> <source name="images/volume-9134b639-c23c-4ff1-91ca-0462c80026d2" protocol="rbd"> <host name="141.108.X.Y1" port="6789" transport="tcp"/> <host name="141.108.X.Y2" port="6789" transport="tcp"/> </source> <auth username="cinder"> <secret type="ceph" uuid="<base 64 ceph secret>"/> </auth> <target bus="virtio" dev="vdb"/> <driver cache="none" error_policy="stop" io="threads" name="qemu" type="raw"/> </disk>

In fact the uuid of the secret used by ovirt to hotplug seems to be the ceph secret (masked here as <base 64 ceph secret>), while libvirt expects the uuid of the libvirt secret, by looking at the instructions http://docs.ceph.com/docs/jewel/rbd/libvirt/. Anyone got it working? Thanks,
Alessandro
