Thanks vor your replay. Yes, I have some issues. In some cases starting or migrating a virtual machine failed.

[ovirt-users] oVirt 4.3 and cinderlib integration (for ceph) on CentOS 7 - centos-release-openstack-pike
At https://www.ovirt.org/develop/release-management/features/storage/cinderlib-integration.html ist described the cinderlib integration into oVirt: Installation: - install centos-release-openstack-pike on engine and all hosts - install openstack-cinder and python-pip on engine - pip install cinderlib on engine - install python2-os-brick on all hosts - install ceph-common on engine and on all hosts Which software versions do you use on CentOS 7 whith oVirt 4.3.10? The package centos-release-openstack-pike, as described at the above-mentioned Managed Block Storage feature page, doesn't exist anymore in the CentOS repositories, so I have to switch to centos-release-openstack-queens or newer (rocky, stein, train). So I get (for using with ceph luminous 12): - openstack-cinder 12.0.10 - cinderlib 1.0.1 - ceph-common 12.2.11 - python2-os-brick 2.3.9 ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/H5BRKSYAHJBLI65G6JEDZIWSQ72OCF3S/

[ovirt-users] Cinderlib managed block storage, ceph jewel
Hi. I tried to use manged block storage to connect our oVirt cluster (Version 4.3.4.3-1.el7) to our ceph storage ( version 10.2.11). I used the instructions from https://ovirt.org/develop/release-management/features/storage/cinderlib-integration.html At the moment, in the ovirt administration portal I can create and delete ceph volumes (ovirt disks) and attach them to virtual machines. If I try to launch a vm with connected ceph block storage volume, starting fails: 2019-07-16 19:39:09,251+02 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.AttachManagedBlockStorageVolumeVDSCommand] (default task-53) [7cada945] Unexpected return value: Status [code=926, message=Managed Volume Helper failed.: ('Error executing helper: Command [\'/usr/libexec/vdsm/managedvolume-helper\', \'attach\'] failed with rc=1 out=\'\' err=\'oslo.privsep.daemon: Running privsep helper: [\\\'sudo\\\', \\\'privsep-helper\\\', \\\'--privsep_context\\\', \\\'os_brick.privileged.default\\\', \\\'--privsep_sock_path\\\', \\\'/tmp/tmpB6ZBAs/privsep.sock\\\']\\noslo.privsep.daemon: Spawned new privsep daemon via rootwrap\\noslo.privsep.daemon: privsep daemon starting\\noslo.privsep.daemon: privsep process running with uid/gid: 0/0\\noslo.privsep.daemon: privsep process running with capabilities (eff/prm/inh): CAP_SYS_ADMIN/CAP_SYS_ADMIN/none\\noslo.privsep.daemon: privsep daemon running as pid 112531\\nTraceback (most recent call last):\\n File "/usr/libexec/vdsm/managedvolume-help er", line 154, in \\nsys.exit(main(sys.argv[1:]))\\n File "/usr/libexec/vdsm/managedvolume-helper", line 77, in main\\n args.command(args)\\n File "/usr/libexec/vdsm/managedvolume-helper", line 137, in attach\\nattachment = conn.connect_volume(conn_info[\\\'data\\\'])\\n File "/usr/lib/python2.7/site-packages/vdsm/storage/nos_brick.py", line 96, in connect_volume\\nrun_as_root=True)\\n File "/usr/lib/python2.7/site-packages/os_brick/executor.py", line 52, in _execute\\nresult = self.__execute(*args, **kwargs)\\n File "/usr/lib/python2.7/site-packages/os_brick/privileged/rootwrap.py", line 169, in execute\\nreturn execute_root(*cmd, **kwargs)\\n File "/usr/lib/python2.7/site-packages/oslo_privsep/priv_context.py", line 205, in _wrap\\nreturn self.channel.remote_call(name, args, kwargs)\\n File "/usr/lib/python2.7/site-packages/oslo_privsep/daemon.py", line 202, in remote_call\\nraise exc_type(*result[2])\\noslo_concurrency.processutils.Pr ocessExecutionError: Unexpected error while running command.\\nCommand: rbd map volume-a57dbd5c-2f66-460f-b37f-5f7dfa95d254 --pool ovirt-volumes --conf /tmp/brickrbd_TLMTkR --id ovirtcinderlib --mon_host 192.168.61.1:6789 --mon_host 192.168.61.2:6789 --mon_host 192.168.61.3:6789\\nExit code: 6\\nStdout: u\\\'RBD image feature set mismatch.
