host upgrade problems galore
by Diggy Mc 15 Sep '21

15 Sep '21

Brief background: Simple environment -- self-hosted engine and two oVirt Node hosts all running 4.4.4. Couple NFS-based data storage domains and a few VLAN-based networks. Upgrading the Hosted Engine from 4.4.4 to 4.4.8 appears to have completed successfully and without incident. I followed the published instructions. :) Problems upgrading the oVirt Node hosts !!! Initialized cluster upgrade. It got as far as rebooting the first host. ERRORS. Said "vdsmd... BAD" Found journal log entry suggesting I run a vdsm config command. Did that and rebooted. VDSM error went away and all looked good. Unfortunately VMs started on that host now were clearly unstable. Ugh! Unusable host. Removed that host from the cluster. Reinstalled from scratch using the 4.4.8 ISO. All went well. Added it to the cluster and deployed the HE to it. No Errors. Unfortunately, it is now stuck in a NonOperational state and I cannot determine why. Please help.

by Vrgotic, Marko 14 Sep '21

14 Sep '21

Dear oVirt, We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months. I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps? Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

HE and Node upgrade procedures
by Diggy Mc 14 Sep '21

14 Sep '21

Where can I find the documentation on the procedure to upgrade the Hosted Engine as well as the oVirt Nodes? Specifically, both the HE and Nodes are currently at 4.4.4 and I would like to upgrade to 4.4.8.3. Also, if I remember correctly, 4.4.4 was the last version to use CentOS Linux 8 and later versions switched to CentOS Stream 8. Will the upgrade procedure automatically switch over to Stream? Is there anything I need to be aware of or concerned with regarding the switch to Stream? Your help and guidance is much appreciated.

virtio-win driver licensing
by simon＠justconnect.ie 14 Sep '21

14 Sep '21

Hi, Can someone clarify the licensing around virtio-win drivers on oVirt 4.4.8 as the following seems to imply a RedHat paid subscrition is required when installing "virtio-win-guest-tools.exe" "2. Program License Grant. Red Hat grants User a non-exclusive, non-transferable license to use the Program during the term of and on systems with fully-paid applicable Red Hat subscription(s) provided User may not: (a) modify, copy, or create any derivative works of the Program; (b) decompile, disassemble or reverse engineer the Program (except to the extent permitted by applicable law); (c) redistribute, encumber, sell, rent, lease, sublicense, or otherwise transfer rights to the Program (except to the extent permitted herein); or (d) remove or alter any trademark, logo, copyright or other proprietary notices, legends, symbols or labels in the Program. Upon expiration of the term set forth above, User will promptly remove, delete or destroy all copies of the Program in its possession." Kind Regards Simon...

Thank you for restreaming the oVirt Conf to China!
by Janos Bonic 14 Sep '21

14 Sep '21

Hey folks, I'm hoping whoever mentioned in the chat that they are rebroadcasting the conference to China is in this mailing list. I owe you a huge thank you! I tried to figure out how to stream to China, but I failed. If you are interested in helping us set up a direct stream or publish to a platform accessible in China next year, please contact me privately so we can coordinate. Janos

about the cloud-init options on the vm portal
by Tommy Sway 13 Sep '21

13 Sep '21

It seems that the options for cloud-init in the VM portal interface are only host name and SSH key, other options that can be seen in the administrator interface are not visible. Is there a solution to this problem? Thanks!

Cannot Start VM After Pausing due to Storage I/O Error
by bob.franzke＠mdaemon.com 13 Sep '21

13 Sep '21

Noticed I had a VM that was 'paused' due to a 'Storage I/O error. I inherited this system from another admin and have no idea where to start figuring this out. We have a 4-node Ovirt cluster with a 5 Manager node. The VM in question is running on a host vm-host-colo-4. Best I can tell the VMs run on a gluster replicated volume replicated between all 4 nodes, with node 1 running as an arbiter node for the gluster volume. Other VMs are running on this host 4 so not sure what the issue is with this one VM. When I look at the status of the gluster volume for this host, I see the self-heal info for the bricks is listed as 'N/A' for this host. All the other hosts in the cluster list this info as 'OK'. When I cd into the gluster directory on host 4, I don't see the same things as I do on the other hosts. I am not sure this is an issue but its just different. When running various gluster commands gluster seems to respond. See below: [root@vm-host-colo-4 gluster]# gluster volume info all Volume Name: gl-colo-1 Type: Replicate Volume ID: 2c545e19-9468-487e-9e9b-cd3202fc24c4 Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: 10.20.101.181:/gluster/gl-colo-1/brick1 Brick2: 10.20.101.183:/gluster/gl-colo-1/brick1 Brick3: 10.20.101.185:/gluster/gl-colo-1/brick1 (arbiter) Options Reconfigured: network.ping-timeout: 30 cluster.granular-entry-heal: enable performance.strict-o-direct: on storage.owner-gid: 36 storage.owner-uid: 36 cluster.choose-local: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: off performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off auth.allow: * user.cifs: off transport.address-family: inet nfs.disable: on performance.client-io-threads: off Volume Name: gl-vm-host-4 Type: Distribute Volume ID: a2ba6b29-2366-4a7e-bda8-2e0574cf4afa Status: Started Snapshot Count: 0 Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 10.20.101.187:/gluster/gl-vm-host-colo-4 Options Reconfigured: network.ping-timeout: 30 cluster.granular-entry-heal: enable network.remote-dio: off performance.strict-o-direct: on storage.owner-gid: 36 storage.owner-uid: 36 auth.allow: * user.cifs: disable transport.address-family: inet nfs.disable: on [root@vm-host-colo-4 gluster]# [root@vm-host-colo-4 gluster]# gluster-eventsapi status Webhooks: http://mydesktop.altn.int:80/ovirt-engine/services/glusterevents +-------------------------+-------------+-----------------------+ | NODE | NODE STATUS | GLUSTEREVENTSD STATUS | +-------------------------+-------------+-----------------------+ | vm-host-colo-1.altn.int | UP | OK | | vm-idev-colo-1.altn.int | UP | OK | | vm-host-colo-2.altn.int | UP | OK | | localhost | UP | OK | +-------------------------+-------------+-----------------------+ [root@vm-host-colo-4 gluster]# gluster volume status gl-vm-host-4 Status of volume: gl-vm-host-4 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick 10.20.101.187:/gluster/gl-vm-host-col o-4 49152 0 Y 33221 Task Status of Volume gl-vm-host-4 ------------------------------------------------------------------------------ There are no active volume tasks I also get a timeout error when doing a 'gluster volume status' on this node. So while some aspects seem fine with the gluster volume, some don't. Should I restart the glusterd daemon or will that mess things up? I am not sure if this is due to something wrong with the gluster volume or with the vm-host's ability to access the data for the VM disk, meaning a true I/O problem. There are two VMs in this state both running on this host and I am not sure how to proceed to get them running again. Should I force this VM to be on a different host by editing the VM or should I try and make it work on the host its on. As mentioned, many other VMs are running on this host so not sure why these two have an issue. Up front apologies here. I am a network engineer and not a VM/Ovirt expert. This was dropped in my lap due to a layoff and could use some help on where to go from here. Thanks in advance for any help.
