Cannot Enable incremental backup
by Jonas 05 Aug '22

05 Aug '22

Hello all I'm trying to create incremental backups for my VMs on a testing cluster and am using the functions from https://gitlab.com/nirs/ovirt-stress/-/blob/master/backup/backup.py. So far it works well, but on some disks it is not possible to enable incremental backups even when the VM is powered off (see screenshot below). Does anyone know why this might be the case and how to activate it? I think I already checked the docs and didn't find anything but feel free to nudge me in the right direction. By the way, is there a backup solution that is somewhat endorsed by the community here? Thank you and kind regards, Jonas Screenshot of oVirt Disk

Adding a GlusterFS Storage Domain
by simon＠justconnect.ie 04 Aug '22

04 Aug '22

This may seem like a simple question but clarification from the experts would be good. When adding a GlusterFS Storage Domain via the engine, do I use the Gluster Storage FQDNs for the Path and backup-volfile-servers mount options Or Do I use the ovirt management network FQDNs. Kind Regards Simon...

Single Peer in Gluster Cluster Failure caused Storage Domain outage
by simon＠justconnect.ie 04 Aug '22

04 Aug '22

Hi All, We have a 3 node HCI cluster with Gluster 2+1 volumes. The first node had a hardware memory failure which caused file corruption to the engine lv and the server would only boot into maintenance mode. For some reason glusterd wouldn't start and one of the volumes became inaccessible with the Storage domain going offline. This caused multiple VMs to go into a paused or shutdown state. Putting the host into maintenance mode and then shutting it down was done in an attempt to allow gluster to continue across 2 nodes (one being the arbiter). Unfortunately this didn't work. The solution was to do the following: 1. Remove the contents of /var/lib/glusterd except for glusterd.info 2. Start glusterd 3. Peer probe one of the other 2 peers 4. Restart glusterd 5. Cross fingers and toes Although this was a successful outcome I would like to know why losing 1 gluster peer caused the outage of a single storage domain and therefore outages of VMs with disks on that storage domain. Kind Regards Simon...

Problem with engine deployment

HI everyone, hope all is good. OS: Centos Stream ovirt 4.5 I'm having problems deploying the hosted engine both through cockpit and cli. I have 3 servers, where through cockpit, I have managed to configure and deploy glusterfs without problems. but when I want to deploy the hosted engine it tells me "No valid network interface has been found". the 3 servers have 2 nic each one, I have created a bond in each one with cockpit and with the name bond0 and in XOR mode. if someone can help me, please. ansible packages installed: [root@vs05 pre_checks]# rpq -qa | ansi -bash: ansi: no se encontró la orden -bash: rpq: no se encontró la orden [root@vs05 pre_checks]# rpq -qa |grep ansi -bash: rpq: no se encontró la orden [root@vs05 pre_checks]# rpm -qa |grep ansi ansible-collection-ansible-posix-1.3.0-1.2.el8.noarch ansible-collection-ansible-netcommon-2.2.0-3.2.el8.noarch ansible-collection-ansible-utils-2.3.0-2.2.el8.noarch gluster-ansible-maintenance-1.0.1-12.el8.noarch gluster-ansible-features-1.0.5-15.el8.noarch ovirt-ansible-collection-2.1.0-1.el8.noarch gluster-ansible-cluster-1.0-5.el8.noarch gluster-ansible-repositories-1.0.1-5.el8.noarch ansible-core-2.12.7-1.el8.x86_64 gluster-ansible-roles-1.0.5-28.el8.noarch gluster-ansible-infra-1.0.4-22.el8.noarch

Q: "vdsm-client Host getAllTasksInfo" Fails (Removing frozen task)
by Andrei Verovski 04 Aug '22

04 Aug '22

Hi, I have frozen task (creating snapshot) on one of my oVirt nodes, and trying to kill it. However, # sudo vdsm-client Host getAllTasksInfo vdsm-client: Command Host.getAllTasksInfo with args {} failed: However, sudo "vdsm-client Host getVMList” and "sudo vdsm-client Host getVMFullList" working fine. # /usr/share/ovirt-engine/setup/dbutils/taskcleaner.sh -v -Z select exists (select * from information_schema.tables where table_schema = 'public' and table_name = 'command_entities'); t SELECT command_id,command_type,root_command_id,command_parameters,command_params_class,created_at,status,return_value,return_value_class,executed FROM GetAllCommandsWithZombieTasks(); So only letter “t” is printed and it is not clear what does it mean. I can run "/usr/share/ovirt-engine/setup/dbutils/taskcleaner.sh -vR” but not sure its not too destructive. What is the problem with "vdsm-client Host getAllTasksInfo” ? Thanks in advance. Andrei

Typo - the server would only boot into ‘emergency’ mode.

Host certificate expired
by Rob B 04 Aug '22

04 Aug '22

Hi, We have a ovirt host in a 'Unassigned' state because its certificate has expired. The ovirt events show... VDSM host1 command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed This is the only host in the cluster, and has local storage so I don't have any options to start the single VM elsewhere. Is there a way to renew the certificate on this host? I have no option to put the host in maintenance mode and 'Enroll Certificate' as its in the unassigned state. The oVirt manager is running version: 4.4.10.7-1.el8 The oVirt host in the bad state is running: ovirt-host-4.4.9-2, vdsm-4.40.100.2-1. Please let me know if you need any more info, and thanks in advance. Rob

HostedEngine Restore woes
by simon＠justconnect.ie 04 Aug '22

04 Aug '22

Hi All, I've been asked to test the HE restore process but after taking a look at the documentation I'm afraid I'm none the wiser. I thought there would be a simple 'restore in situ' option but it appears not. My environments were build using ansible with a hostedengine .json answer file. From what I've read so far it appears that a new HE VM needs to be built with new engine storage etc

Re: Six node HCI

It would make more sense to odentify the root cause.Can you check if all oVirt nodes are in the TSP:gluster pool listAlso, check that the Engine's volume is available from all nodes -> should be mounted and listable:ls -l /rhev/data-center/mnt/glusterSD/<host>:_<volume name> Best Regards,Strahil Nikolov On Tue, Aug 2, 2022 at 8:45, Gaurang Patel<gaurang.patel(a)allotgroup.com> wrote:  Hi, I am very new to Ovirt 6 Node Gluster.
