Hello, One of our admins accidentally added one of available LUN disks to storage domain. Now we are not able to remove it as additional storage from it. There was no data written on it. on host it was removed from vg group (vgreduce) , but on site it is still in use (greyed out) (vgreduce had no issues removing pvdisk from it) multipath -ll shows it as unused, dmsetup status shows some values related to this lun: OS: rhel 7.9 package ovirt 4.3 cluster: yes Any idea how to remove it without corrupting datadomain ? is it safe to remove it with dmsetum remove?

Some problems with ovirt
by אריה קלטר 03 Sep '22

03 Sep '22

Hi, I have two ovirt clusters. 1. 4.3 cluster with single node (was 3 nodes in the past) 2. 4.5.2 cluster with 3 nodes. the problem was also on oVirt-4.5 node with a matching engine version but the cluster configured on version 4.6 because I did have a problem upgrading one of the nodes, I also lost the engine because of gluster volume sync issue between the hosts, so I formatted the problematic node using the 4.5.2 node iso and created a new engine on it, and attached 2 of the existing nodes and did upgrade on the nodes using the new engine. About the new cluster: 1. migration between hosts - almost all the time looks like it succeeds, but the VM is not responding after the successful migration. 2. run reboot inside of the VM - in a high percent of the time it just hung instead of reboot. With 100% CPU. In status "Reboot in Progress", but after some time the status changed to "Up" incorrectly. I tried on the clean images of ubuntu and centos from ovirt-image-repository. I imported a server from the 4.3 cluster to the new cluster, on the old cluster it reboots correctly but in the new cluster it doesn't. I tried it both with gluster and with nfs. Any idea how to solve both problems? Regards, Arye

I was looking at those studies but not sure how old they are. What I can see is that our oVirt deployment seems bigger than any of those studies but I can be wrong. ------ Original Message ------ Received: 01:08 AM MDT, 09/02/2022 From: Sandro Bonazzola <sbonazzo(a)redhat.com> To: jlhm(a)usa.net Cc: oVirt Users <users(a)ovirt.org> Subject: Re: [ovirt-users] How many oVirt cluster, hosts and VMs do you have running? > Would something like an oVirt counter help? > https://github.com/oVirt/ovirt-site/pull/3056 > > > Il giorno ven 2 set 2022 alle ore 08:26 ha scritto: > > > Hi, just trying to understand how our oVirt deployment compare to others. > > - 75 cluster (and 75 Data centers as we map them 1 to 1 due to security > > requirements) spanning +3 data centers > > - 328 oVirt servers > > - +1900 VMs running > > > > Majority are still on 4.3 (CentOS 7) but our engines (4 of them) runs > > RedHat 8/oVirt 4.4.

How many oVirt cluster, hosts and VMs do you have running?
by jlhm＠usa.net 02 Sep '22

02 Sep '22

Hi, just trying to understand how our oVirt deployment compare to others. - 75 cluster (and 75 Data centers as we map them 1 to 1 due to security requirements) spanning +3 data centers - 328 oVirt servers - +1900 VMs running Majority are still on 4.3 (CentOS 7) but our engines (4 of them) runs RedHat 8/oVirt 4.4. Working to upgrade all hypervisors to RedHat 8 (or Rocky 8)/oVirt 4.4. When that is done we will start to upgrade to latest oVirt version but it takes time due to the size of our environment and we move slowly to ensure stability.

Ubuntu NFS
by thilburn＠generalpacific.com 01 Sep '22

01 Sep '22

Hello, I was having trouble with getting an Ubuntu 22.04 NFS share working and after searching for hours I was able to figure out what was needed. Below is what I found if anyone else runs into this. My error was engine.log "...Unexpected return value: Status [code=701, message=Could not initialize cluster lock: ()]" Host supervdsm.log -open error -13 EACCES: no permission to open /ThePath/ids -check that daemon user sanlock *** group sanlock *** has access to disk or file. The fix was changing /etc/nfs.conf manage-gids=y ( Which is the default ) to # manage-gids=y ( Commenting this sets the default which is no ) It looks like in the past the fix was to change /etc/default/nfs-kernel-server Line RPCMOUNTDOPTS="--manage-gids" which I didn't need to change.

how kill backup operation
by Diego Ercolani 01 Sep '22

01 Sep '22

Hello I saw there are other thread asking how to delete disk snapshots from backup operation. We definitively need a tool to kill pending backup operations and locked snapshots. I Think this is very frustrating ovirt is a good piece of software but it's very immature in a dirty asyncronous world. We need a unified toolbox to clean manually and do database housekeeping.

Interested in contributing with Spanish translation.
by Luis Pereida 01 Sep '22

01 Sep '22

Hello, My name is Luis Pereida, I am Mexican, from Guadalajara and I am currently an application security specialist. Some time ago I met the O-Virt project and it helped me a lot to solve many situations where virtualization was the perfect option. Since some time ago I have been thinking about how to contribute to the project, and talking with some friends, they would like to have documentation in Spanish. Although English is basic for us, many times the context or expressions are hard to understand. I would like to help with that. How can I do it? I see that it is necessary to use a Zanata account. How can I get an account? Regards and thanks for being so supportive of the community.

Hi, I have engine version 4.4.10.7-1.el8, is it possible to set up new node host on CentOS Stream 9, or I need to upgrade engine to version 4.5 first (which is not right now possible because of some quite old nodes) ? Thanks Andrei

Hello We have got an Production ovirt installation with 1 datacenter and 2 clusters. Default Cluster has got 2 hosts in it. kvm01 and kvm02. PrimarySite cluster has got 2 hosts in it. kvm03 and kvm04 Our Self hosted engine is running on kvm01. We need to migrate the Selfhosted-engine to kvm03 or kvm04 since the hosts kvm01 and kvm02 hosts are going to be retired. Anyone has any idea how this can be accomplished?
