Linux VMs cannot boot from software raid0
by Strahil Nikolov 17 Jan '22

17 Jan '22

Hi All, I recently migrated from 4.3.10 to 4.4.9 and it seems that booting from software raid0 (I have multiple gluster volumes) is not possible with Cluster compatibility 4.6 . I've tested creating a fresh VM and it also suffers the problem. Changing various options (virtio-scsi to virtio, chipset, VM type) did not help . Booting from rescue media shows that the data is still there, but grub always drops to rescue. Any hints are welcome. Host: CentOS Stream 8 with qemu-6.0.0oVirt 4.4.9 (latest)VM OS: RHEL7.9/RHEL8.5 Best Regards,Strahil Nikolov

how to debug sanlock issue
by Jiří Sléžka 16 Jan '22

16 Jan '22

Hello, I have 3 node HCI cluster with glusterfs. oVirt 4.4.9.5-1. In last 2 weeks I experience 2 outages where HE and all/some vms were restarted. While digging in logs I can see that sanlock cannot renew leases and it leads to killing vms as is very good described in [1]. It looks to me like some hw issue with one of the hosts but cannot find which one. for example today's outage restarted vms on hosts 1 and 2 but not 3. Sanlock logs there are these lines in /var/log/messages on host 2 (ovirt-hci02) Jan 13 08:27:25 ovirt-hci02 sanlock[1263]: 2022-01-13 08:27:25 1416706 [341378]: s7 delta_renew read timeout 10 sec offset 0 /rhev/data-center/mnt/glusterSD/10.0.4.11:_vms/6de5ae6d-c7cc-4292-bdbf-10495a38837b/dom_md/ids Jan 13 08:28:59 ovirt-hci02 sanlock[1263]: 2022-01-13 08:28:59 1416800 [341257]: write_sectors delta_leader offset 1024 rv -202 /rhev/data-center/mnt/glusterSD/10.0.4.11:_engine/816a3d0b-2e10-4900-b3cb-4a9b5cd0dd5d/dom_md/ids Jan 13 08:29:27 ovirt-hci02 sanlock[1263]: 2022-01-13 08:29:27 1416828 [4189968]: write_sectors delta_leader offset 1024 rv -202 /rhev/data-center/mnt/glusterSD/10.0.4.11:_engine/816a3d0b-2e10-4900-b3cb-4a9b5cd0dd5d/dom_md/ids but not on hosts 1 and 3. Could it indicate that there could be storage related problem on host 1? could you please suggest further/better debugging approach?

External engine CentOS 8.4 and 4.4.8 to Rocky Linux 8.5 and 4.4.9
by Gianluca Cecchi 15 Jan '22

15 Jan '22

Just wanted to share what in subject and feedback/comments welcome. Starting env is an external engine on CentOS 8.4, updated up to late September, with 4.4.8 async 2 (ovirt-engine-4.4.8.6-1.el8.noarch.rpm) and kernel 4.18.0-305.19.1.el8_4 [g.cecchi@ovmgr1 ~]$ cat /etc/centos-release CentOS Linux release 8.4.2105 I migrated to Rocky Linux 8.5 and then run engine-setup to take it to current 4.4.9 level. The system is a VM on a vSphere environment. Currently there are 3 hosts with CentOS 8.4, that I'm going then to migrate to Rocky Linux too. Downloaded the current migration script from https://raw.githubusercontent.com/rocky-linux/rocky-tools/main/migrate2rock… chmod +x migrate2rocky.sh My engine needs a proxy to exit on the internet and the script doesn't check my /etc/yum.conf configuration so I set export https_proxy=http://my_proxy:my_proxy_port export http_proxy=http://my_proxy:my_proxy_port (not sure if this necessary...) otherwise when you run the script you get curl: (7) Failed to connect to dl.rockylinux.org port 443: Connection timed out Error downloading the Rocky Linux signing key. then as root ./migrate2rocky.sh -r notable things observed: . some packages from ovirt repos are gathered too... I don't know if correct in this stage... Running dnf update before we attempt the migration. Last metadata expiration check: 0:00:47 ago on Thu Jan 13 11:56:21 2022.

This is required because the days until the end of the certificate's life expire, waiting for the next day in order to understand the result of deploying a new certificate is a strange situation Thanks, k

VFs Mellanox
by Jorge Visentini 12 Jan '22

12 Jan '22

Hi all. Is it possible to use the Mellanox VFs with bridge from VMs? My switch is configured as a trunk accepting VLAN 1000. I configured Mellanox ConnectX-3 to create 2 VFs. 1 VF I used for iSCSI on VLAN 1000 (it worked) and another VF I set up a bridge on VLAN 1000 to use on the VMs. What is happening is that the VM's mac hits the switch on VLAN 1000, but has no traffic. Below are some images of my setup... *Switch:* [image: image.png] *oVirt Host:* [image: image.png] [image: image.png] [image: image.png] [image: image.png] [image: image.png] [image: image.png] *oVirt Guest VM:* [image: image.png] Can anyone give a little help? All the best! -- Att, Jorge Visentini +55 55 98432-9868

Hi Team due to some reasons one of our slef hosted engine went down, hence we provisioned new centos vm and restored the hosted engine backup file. After restoring we could see all the Datacenter, cluster, storage, hosts and vm entities in restored ovirt engine but they all are offline. please help us how to we connect all the running hosts and storage domain, vms back to restored hosted engine. do we need to get a down time for all the vms to restore the hosts? how do I activate all the existing storage domains as is.

Gluster Hook differences between fresh and old clusters

Hi All, recently I have migrated from 4.3.10 to 4.4.9 and it seems something odd is happening. Symptoms: - A lot of warnings for Gluster hook discrepancies - Trying to refresh the hooks via the sync button fails (engine error: https://justpaste.it/827zo ) - Existing "Default" cluster tracks more hooks than a fresh new cluster New cluster hooks: http://i.imgur.com/FEL2Z1D.png Migrated cluster: https://i.imgur.com/L8dWYZY.png What can I do to resolve the issue ? I've tried to resync the hooks, move away /var/lib/glusterd/hooks/1/ and reinstall gluster packages, try to resolve via the "Resolve Conflicts" in the UI and nothing helped so far. Best Regards, Strahil Nikolov
