Hosts force fencing after engine upgrade 4.3->4.4

by ernest.beinrohr＠axonpro.sk

Hi, I was in the process of upgrading 4.3 to 4.4. First I upgraded the engine and the hosts are still 4.3. The engine has started fencing my hosts as there has been 1 (one) connection problem to VDSM on the host. I Basically, the engine at some random time connects to vdsm, this crashes (didnt on e4.3) and after a few seconds the engine issues a fencing and all my VMs are taken down .... This happend with multiple hosts at random times. Can this be attributed to the unmatched hosts? Or should I consider an engine restore to 4.3? Engine ovirt-engine-4.4.10.7-1.el8.noarch: 2022-11-21 10:40:05,788+01 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.UploadStreamVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-16) [258de39e] Command 'UploadStreamVDSCommand(HostName = galador, UploadStreamVDSCommandParameters:{hostId='146456e8-02fd-4 ce0-9140-13032d9a52ca'})' execution failed: java.net.SocketException: Connection reset by peer (Write failed) HOST vdsm-4.30.46-1.el7.x86_64: 2022-11-21 10:40:05,785+0100 ERROR (Reactor thread) [vds.dispatcher] uncaptured python exception, closing channel <yajsonrpc.betterAsyncore.Dispatcher connected ('::ffff:10.10.80.100', 37772, 0, 0) at 0x7f73cba72710> (<type 'exceptions.TypeError'>:object of type 'NoneType' has no len() [/usr>

activate incremental backup on disk with ansible ovirt_disk module

by Nathanaël Blanchet

Hello, I've struggled for hours with enabling incremental backup on disk level with the ansible ovirt.ovirt.ovirt_disk module: - name: modify incremental backup state ovirt.ovirt.ovirt_disk: auth: "{{ ovirt_auth }}" id: "{{disk_id}}" backup: "incremental" But the disk never gets into an incremental state. What's the matter? PS: I know I can do the same with curl, but this is not what I want.

oVirt v4.5 - Error updating oVirt hosts for ovirt-hosted-engine-setup-2.6.6-1.el8.noarch

by Erkan E

Hello, Upgrading oVirt hosts fails via the ovirt Compute -> Hosts -> Installation -> Upgrade menu. I get the dependency error message below, when trying to upgrade my oVirt hosts running on Rocky Linux 8.7. Its oVirt repo version is centos-release-ovirt45-8.7-3.el8s.noarch. I have no chance to try it with RHEL or CentOS Stream. "msg" : "Depsolve Error occurred: \n Problem: package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch conflicts with ansible-core >= 2.13 provided by ansible-core-2.13.3-1.el8.x86_64\n - cannot install the best update candidate for package ovirt-hosted-engine-setup-2.6.5-1.el8.noarch\n - cannot install the best update candidate for package ansible-core-2.12.2-4.el8_6.rocky.0.1.x86_64", Thank you.

Yet another hosted engine deployment fails 4.5.2

by simon＠justconnect.ie

New install (4.5.2) and back to square one - install fails. Now the ovirtmgmt interface isn't created but vnet0 is - no idea what the cause is as there's nothing in the setup logs. oVirt = 1 step forward 3 steps back - and now with almost no support as the project is heading towards the scrap heap - So frustrating. Deadline for this install is Monday so I guess it's back to 4.4.6 install followed by upgrade path - Arghhhhhhhhhhhhhhhhhhhhhg!

multipath active-passive vs active-active

by Enrico Becchetti

Dear All, I have been using ovirt for many years. I've got six servers , two HPE MSA storage and a fiber channel network with two Brocade 8/20q. oVirt has got two domain storage, one volume for each MSA. Now I have only one MSA online. As you know multipath was configured throught vdsm. This is the output of the multipath command from one of the servers: [root@infm-vm04 etc]# multipath -ll 3600c0ff0003c465b6510f85b01000000 dm-2 HPE ,MSA 2050 SAN size=14T features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='service-time 0' prio=1 status=active | `- 2:0:0:0 sdc 8:32 active ready running |-+- policy='service-time 0' prio=1 status=enabled | `- 1:0:0:0 sdb 8:16 active ready running |-+- policy='service-time 0' prio=1 status=enabled | `- 2:0:1:0 sdd 8:48 active ready running `-+- policy='service-time 0' prio=1 status=enabled `- 1:0:1:0 sde 8:64 active ready running With this setup I think there is an active path and the other is in standby state. So, Id like to know if ovrt support active-active mode and how can I make this settings ? /This is the current multipath.conf// // //defaults {// // polling_interval 5// // no_path_retry 4// // user_friendly_names no// // flush_on_last_del yes// // fast_io_fail_tmo 5// // dev_loss_tmo 30// // max_fds 4096// //}// //blacklist {// // protocol "(scsi:adt|scsi:sbp)"// //}// //devices {// // device {// // all_devs yes// // no_path_retry 4// // }// //}// / Thanks a lot.

expired host certificate

by Diggy Mc

I'm running oVirt 4.4. The "libvirtd" service won't start and it appears to be because of an expired certificate. How do I create and install a new certificate on the host. Your help is much appreciated. -- Diggy ---
