[kolla][cinder][glance][ceph] Corrupt image while downloading from Ceph
by Giuseppe Sannino 03 Dec '19

03 Dec '19

Hi community, need your help. *>>> Background <<<* I'm using kolla-ansible 8.0.0 to deploy a 1+3 "Stein" cluster. Ceph is used as backend. The configuration is a bit peculiar. The control runs on a VM hosted in a separate network compared to the one where the baremetal servers hosting the OS Compute services are. On the Compute Hosts, we have the following services: glance_api neutron_metadata_agent neutron_l3_agent neutron_dhcp_agent neutron_openvswitch_agent openvswitch_vswitchd openvswitch_db nova_compute nova_libvirt nova_ssh cinder_backup cinder_volume chrony cron kolla_toolbox fluentd Services APIs and Authentication run on the controller. In a standard "lab configuration" everything works fine. *>>> Fault Scenario <<<* We are trying to verify possible issues (and the way to work around them) in case latency between Controller and Compuite increases. And we have found one quite fast. Basically, if you try to create a volume from a RAW image (stored in Ceph) it will fail. >From glance-api.log on the controller: 2019-12-03 16:00:11.840 27 INFO eventlet.wsgi.server [req-225aae45-ad93-40f5-835d-027f93e3307d 615252134b844dbeb7acc34219e431e6 0049baebd0f742de915b11ec18509803 - default default] Traceback (most recent call last): File "/var/lib/kolla/venv/lib/python2.7/site-packages/eventlet/wsgi.py", line 572, in handle_one_response write(b''.join(towrite)) File "/var/lib/kolla/venv/lib/python2.7/site-packages/eventlet/wsgi.py", line 518, in write wfile.writelines(towrite) File "/usr/lib64/python2.7/socket.py", line 334, in writelines self.flush() File "/usr/lib64/python2.7/socket.py", line 303, in flush self._sock.sendall(view[write_offset:write_offset+buffer_size]) File "/var/lib/kolla/venv/lib/python2.7/site-packages/eventlet/greenio/base.py", line 401, in sendall tail = self.send(data, flags) File "/var/lib/kolla/venv/lib/python2.7/site-packages/eventlet/greenio/base.py", line 395, in send return self._send_loop(self.fd.send, data, flags) File "/var/lib/kolla/venv/lib/python2.7/site-packages/eventlet/greenio/base.py", line 382, in _send_loop return send_method(data, *args) error: [Errno 104] Connection reset by peer >From the cinder-volume.log on the computes: : 019-12-03 16:00:15.932 34 ERROR oslo_messaging.rpc.server None, None) 2019-12-03 16:00:15.932 34 ERROR oslo_messaging.rpc.server File "/var/lib/kolla/venv/lib/python2.7/site-packages/cinder/image/image_utils.py", line 410, in fetch 2019-12-03 16:00:15.932 34 ERROR oslo_messaging.rpc.server reason=reason) 2019-12-03 16:00:15.932 34 ERROR oslo_messaging.rpc.server ImageDownloadFailed: Failed to download image 6e7bb902-917e-4c9e-ba9f-3ee811a2502a, reason: IOError: 32 Corrupt image download.

We have tried with: Cirros Raw (39MB) => It works Ubuntu18 QCOW2 (328MB) => It works Ubuntu18 Raw (2.2GB) => IT FAILS !!!! Any suggestion about where to address our effort?

Re: [External] Re: [openstack-community] how do I revert a volume snapshot?

John, Sorry I misread what you were trying to do. I thought you wanted to create a new instance with the snapshot not revert to it. I've included the link for how to revert volumes. https://docs.openstack.org/cinder/pike/admin/blockstorage-volume-backups.ht… I'm also forwarding this email to the OpenStack Discuss list which is the appropriate list for dev and ops issues.

Hi all. Just a quick one. I can't find the settings for VMs auto start after a computer node reboots. Can you point me to the right docs? Which one is it? And you need to add it on nova scheduler right? Cheers -- *Alfredo*

[all] Shanghai PTG Feedback
by Kendall Nelson 02 Dec '19

02 Dec '19

Hello Everyone! Now that we've had a few weeks to catch up after the summit and marinate on everything we accomplished together there, we wanted to take a sec to see if anyone had feedback. Normally we would have held a lunchtime feedback session, but due to venue restrictions, we didn't have a good place to do things like normal so we created the etherpad[1] and are distributing it this way :) Hope to hear everyone's feedback! Thanks! -the Kendalls (diablo_rojo & wendallkaters) [1]https://etherpad.openstack.org/p/PVG-PTG-feedback
