Nodes with a version and others with anothers

Hi everyone is it recommendable to have nodes with ovirt host with a version and others nodes with another version? for example 5 nodes with this description Versión SO -: RHEL - 7 - 6.1810.2.el7.centos Descripción de SO: CentOS Linux 7 (Core) Versión del kernel: 3.10.0 - 957.10.1.el7.x86_64 Versión KVM: 2.12.0 - 18.el7_6.3.1 Versión LIBVIRT: libvirt-4.5.0-10.el7_6.6 Versión VDSM: vdsm-4.20.46-1.el7 Versión de SPICE: 0.14.0 - 6.el7_6.1 Versión GlusterFS: [N. D.] Versión CEPH: librbd1-10.2.5-4.el7 And a node with ths Versión SO -: RHEL - 7 - 5.1804.5.el7.centos Descripción de SO: oVirt Node 4.2.7.1 Versión del kernel: 3.10.0 - 862.14.4.el7.x86_64 Versión KVM: 2.10.0 - 21.el7_5.7.1 Versión LIBVIRT: libvirt-3.9.0-14.el7_5.8 Versión VDSM: vdsm-4.20.43-1.el7 Versión de SPICE: 0.14.0 - 2.el7_5.5 Versión GlusterFS: glusterfs-3.12.15-1.el7 Versión CEPH: librbd1-0.94.5-2.el7

Re: Gluster volume not responding

Hi Simon, I doubt the system needs tuning from network perspective. I guess you can run some 'screen'-s which a pinging another system and logging everything to a file. Best Regards, Strahil Nikolov В петък, 9 октомври 2020 г., 01:05:22 Гринуич+3, Simon Scott <simon(a)justconnect.ie> написа: Thanks Strahil. I have found between 1 & 4 Gluster peer rpc-clnt-ping timer expired messages in the rhev-data-center-mnt-glusterSD-hostname-strg:_pltfm_data01.log on the storage network IP. Of the 6 Hosts only 1 does not have these timeouts. Fencing has been disabled but can you identify which logs are key to identifying the cause please. It's a bonded (bond1) 10GB ovirt-mgmt logical network and Prod VM VLAN interface AND a bonded (bond2) 10GB Gluster storage network. Dropped packets are seen incrementing in the vdsm.log but neither ethtool -S or kernel logs are showing dropped packets. I am wondering if they are being dropped due to the ring buffers being small.

Based on this one I make the following conclusions: 1. Issue is reoccuring 2. You most probably have a network issue Have you checked the following: - are there any ping timeouts between fuse clients and gluster nodes - Have you tried to disable fencing and check the logs after the issue reoccurs - Are you sharing Blackup and Prod networks ? Is it possible some backup/other production load in your environment to "black-out" your oVirt ? - Have you check the gluster cluster's logs for anything meaningful ? Best Regards, Strahil Nikolov

Moving VM disks from one storage domain to another. Automate?
by Green, Jacob Allen /C 08 Oct '20

08 Oct '20

I am looking for an automated way, via Ansible to move a VM disk from one storage domain to another. I found the following, https://docs.ansible.com/ansible/latest/modules/ovirt_disk_module.html and while it mentions copying a VM disk image from one domain to another it does not mention a live storage migration. Which is what I am looking to do. I want to take roughly 100 VMs and move their disk images from one domain to another that is available to the datacenter in some automated/scripted fashion. I am just curious if anyone out there has had to do this and how they tackled it. Or perhaps I am missing some easy obvious way, other than clicking all the disks and clicking move. However from the looks of it, if I did click all the disk and selected move, it appears RHV tries to do them all at once, which is probably not ideal, I would like it to move the disks in a serial One after another fashion, to conserve throughput and IO. I also did not see anything on Ansible galaxy or the ovirt github that would do this. Thank you.

Hi, Every Monday and Wednesday morning there are gluster connectivity timeouts but all checks of the network and network configs are ok.

Hi all, For a group of users added to ovirt through AD, which role should one add to an ISO for the group to be able to select an ISO when creating VM's in the VM portal? Thanks. Kim

[ANN] oVirt 4.4.3 Fourth Release Candidate is now available for testing
by Lev Veyde 08 Oct '20

08 Oct '20

oVirt 4.4.3 Fourth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.3 Fourth Release Candidate for testing, as of October 8th, 2020. This update is the third in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer * oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Hi Lukaz, Backup using the new incremental backup API is supported only for running VMs. On Thu, 8 Oct 2020 at 12:36, Łukasz Kołaciński <l.kolacinski(a)storware.eu> wrote: > Hello, > While trying to backup stopped VM (with POST on > /ovirt-engine/api/vms/b79b34c0-d8db-43e5-916e-5528ff7bcfbe/backups) I got > the response: > > <?xml version="1.0" encoding="UTF-8" standalone="yes"?> > <fault> > <detail>[Cannot backup VM.
