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.

> It's possible to get, may be from Postgres, the host certificate date? > Engine run this check sometimes, but trigger this check seems impossible Anybody? @Sandro please help engine make check once per day and print to logs How can we run a manual check or see info in PostgreSQL database? 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 13 Jan '22

13 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

Gluster Hook differences between fresh and old clusters
by Strahil Nikolov 11 Jan '22

11 Jan '22

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

Hi all, I'm trying to remove a snapshot from a HA VM in a setup with glusterfs (2 nodes C8 stream oVirt 4.4 + 1 arbiter C8). The error that appears in the vdsm log of the host is: 2022-01-10 09:33:03,003+0100 ERROR (jsonrpc/4) [api] FINISH merge error=Merge failed: {'top': '441354e7-c234-4079-b494-53fa99cdce6f', 'base': 'fdf38f20-3416-4d75-a159-2a341b1ed637', 'job': '50206e3a-8018-4ea8-b191-e4bc859ae0c7', 'reason': 'Unable to get volume info for domain 574a3cd1-5617-4742-8de9-4732be4f27e0 volume 441354e7-c234-4079-b494-53fa99cdce6f'} (api:131) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/livemerge.py", line 285, in merge drive.domainID, drive.poolID, drive.imageID, job.top) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5988, in getVolumeInfo (domainID, volumeID)) vdsm.virt.errors.StorageUnavailableError: Unable to get volume info for domain 574a3cd1-5617-4742-8de9-4732be4f27e0 volume 441354e7-c234-4079-b494-53fa99cdce6f During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 124, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 776, in merge drive, baseVolUUID, topVolUUID, bandwidth, jobUUID) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5833, in merge driveSpec, baseVolUUID, topVolUUID, bandwidth, jobUUID) File "/usr/lib/python3.6/site-packages/vdsm/virt/livemerge.py", line 288, in merge str(e), top=top, base=job.base, job=job_id) The volume list in the host differs from the engine one: HOST: vdsm-tool dump-volume-chains 574a3cd1-5617-4742-8de9-4732be4f27e0 | grep -A10 0b995271-e7f3-41b3-aff7-b5ad7942c10d image: 0b995271-e7f3-41b3-aff7-b5ad7942c10d - fdf38f20-3416-4d75-a159-2a341b1ed637 status: OK, voltype: INTERNAL, format: COW, legality: LEGAL, type: SPARSE, capacity: 53687091200, truesize: 44255387648 - 10df3adb-38f4-41d1-be84-b8b5b86e92cc status: OK, voltype: LEAF, format: COW, legality: LEGAL, type: SPARSE, capacity: 53687091200, truesize: 7335407616 ls -1 0b995271-e7f3-41b3-aff7-b5ad7942c10d 10df3adb-38f4-41d1-be84-b8b5b86e92cc 10df3adb-38f4-41d1-be84-b8b5b86e92cc.lease 10df3adb-38f4-41d1-be84-b8b5b86e92cc.meta fdf38f20-3416-4d75-a159-2a341b1ed637 fdf38f20-3416-4d75-a159-2a341b1ed637.lease fdf38f20-3416-4d75-a159-2a341b1ed637.meta ENGINE: engine=# select * from images where image_group_id='0b995271-e7f3-41b3-aff7-b5ad7942c10d'; -[ RECORD 1 ]---------+------------------------------------- image_guid | 10df3adb-38f4-41d1-be84-b8b5b86e92cc creation_date | 2022-01-07 11:23:43+01 size | 53687091200 it_guid | 00000000-0000-0000-0000-000000000000 parentid | 441354e7-c234-4079-b494-53fa99cdce6f imagestatus | 1 lastmodified | 2022-01-07 11:23:39.951+01 vm_snapshot_id | bd2291a4-8018-4874-a400-8d044a95347d volume_type | 2 volume_format | 4 image_group_id | 0b995271-e7f3-41b3-aff7-b5ad7942c10d _create_date | 2022-01-07 11:23:41.448463+01 _update_date | 2022-01-07 11:24:10.414777+01 active | t volume_classification | 0 qcow_compat | 2 -[ RECORD 2 ]---------+------------------------------------- image_guid | 441354e7-c234-4079-b494-53fa99cdce6f creation_date | 2021-12-15 07:16:31.647+01 size | 53687091200 it_guid | 00000000-0000-0000-0000-000000000000 parentid | fdf38f20-3416-4d75-a159-2a341b1ed637 imagestatus | 1 lastmodified | 2022-01-07 11:23:41.448+01 vm_snapshot_id | 2d610958-59e3-4685-b209-139b4266012f volume_type | 2 volume_format | 4 image_group_id | 0b995271-e7f3-41b3-aff7-b5ad7942c10d _create_date | 2021-12-15 07:16:32.37005+01 _update_date | 2022-01-07 11:23:41.448463+01 active | f volume_classification | 1 qcow_compat | 0 -[ RECORD 3 ]---------+------------------------------------- image_guid | fdf38f20-3416-4d75-a159-2a341b1ed637 creation_date | 2020-08-12 17:16:07+02 size | 53687091200 it_guid | 00000000-0000-0000-0000-000000000000 parentid | 00000000-0000-0000-0000-000000000000 imagestatus | 4 lastmodified | 2021-12-15 07:16:32.369+01 vm_snapshot_id | 603811ba-3cdd-4388-a971-05e300ced0c3 volume_type | 2 volume_format | 4 image_group_id | 0b995271-e7f3-41b3-aff7-b5ad7942c10d _create_date | 2020-08-12 17:16:07.506823+02 _update_date | 2021-12-15 07:16:32.37005+01 active | f volume_classification | 1 qcow_compat | 2 However in the engine gui I see only two snapshots ID: 1- 10df3adb-38f4-41d1-be84-b8b5b86e92cc (status ok) 2- 441354e7-c234-4079-b494-53fa99cdce6f (Disk status illegal) So the situation is: - on the host I see two volumes, status OK - on the engine GUI I see two volumes, one OK and the other one, disk in illegal status - on the engine DB I see three volumes, that are the combo of the two previous situations I would avoid restarting the VM, any advice for fixing this messy situation? I can attach engine log/vdsm.log Thank you for your time and help, Francesco

Re: How to debug "Non Operational" host

Usually, it looks like this: No more information than Non Operational. I have yet been able to mount vmstore. Are there any tricks that I can try to accomplish this? It seems to me that it is something in vdsm that is not working.
