You can go with 512 emulation and later you can recreate the brick without that emulation (if there are benefits of doing so). After all, you gluster is either replica 2 arbiter 1 or a replica 3 volume.

Re: Fwd: Unable to Upgrade

Hi Anton, There is nothing special for upgrading HCI env with Gluster. Bellow steps will be enough: 1- Stop glusterd service in one node which needs to be upgraded. 2- upgrade that node and start glusterd service. 3- wait heal to be completed. 4- continue same procedure for other nodes. In your case can you please restar glusterd in all nodes and check. If it's still not working please share glusterd log? Also please share "gluster volume status" out put.

change connection string in db
by olaf.buitelaar＠gmail.com 01 Oct '19

01 Oct '19

Dear oVirt users, I'm currently migrating our gluster setup, so i've done a gluster replace brick to the new machines. Now i'm trying to update the connection strings of the related storage domains including the one hosting the ovirt-engine (which i believe cannot be brought down for maintenance). At the same time i'm trying to disable the "Use managed gluster volume" feature. i've had tested this in a lab setup, but somehow i'm running into issues on the actual setup. On the lab setup it was enough to run a query like this; UPDATE public.storage_server_connections SET "connection"='10.201.0.6:/ovirt-kube',gluster_volume_id=NULL,mount_options='backup-volfile-servers=10.201.0.1:10.201.0.2:10.201.0.3:10.201.0.5:10.201.0.4:10.201.0.7:10.201.0.8:10.201.0.9' WHERE id='29aae3ce-61e4-4fcd-a8f2-ab0a0c07fa48'; on the live setup i also seem to run a query like this; UPDATE public.gluster_volumes SET task_id=NULL WHERE id='9a552d7a-8a0d-4bae-b5a2-1cb8a7edf5c9'; i couldn't really find where this task_id relates to, but it does make the checkbox for "Use managed gluster volume" being unchecked in the web interface. in the lab setup it was enough to run within the hosted engine; - service ovirt-engine restart and then bring an ovirt-host machine to maintenance, and active it again. and the changed connection string was being mounted in the /rhev/data-center/mnt/glusterSD/ directory. Also the vm's after being shutdown and brought up again, started using the new connection string. But now on the production instance, when i restart the engine the connection string is restored to the original values in the storage_server_connections table. I don't really understand where the engine gathers this information from. Any advice on how to actually change the connection strings would by highly appreciated. Thanks Olaf

Creating vm from snapshot via API
by Aleksei Ivanovich 01 Oct '19

01 Oct '19

Hi. I'm trying to create vm from a snapshot using API. If I just provide the new vm name, source snapshot ID and cluster name the new vm is been created successfully on the same storage domain. But if I additionally provide diskattachments to create it on another storage I get error: "Cannot add VM. One or more provided storage domains are either not in active status or of an illegal type for the requested operation". I can't find the reason why I can't create vm on another storage via API while I can do the same via web-portal. My oVirt Engine version is 4.1.1.8-1.el7.centos. Here is my code: curl.exe -k -u "user@domain.suffix:*************" -H "Content-Type: application/xml" -H "Accept: application/xml" -X POST https://192.168.0.1/ovirt-engine/api/vms -d "<vm><name>vm-Test1</name><snapshots><snapshot id=\"4b73c79b-efed-4362-8843-91f5cc2d9775\"/></snapshots><cluster><name>MyCluster</name></cluster><disk_attachments><disk_attachment><disk><image_id>6525c157-4e73-440b-adc8-596f1d03ef3c</image_id><storage_domains><storage_domain id=\"52a003d7-cec1-473e-b521-1a551f55abd1\"/></storage_domains></disk></disk_attachment></disk_attachments></vm>" The answer is: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>[Cannot add VM.

What happens when it complain that there is no VGs ? When you run 'vgs' what is the output? Also, take a look into https://www.redhat.com/archives/linux-lvm/2016-February/msg00012.html I have the feeling that you need to disable all lvs - not only the thin pool, but also the thin LVs (first).

Actually, I don't have any choice at the moment because it is a single node setup. :) I think this is a distributed volume from the research I have performed. I posted the lvchange command in my last post, this was the result- I ran the command lvchange -an /dev/gluster_vg1/lv_datadisks When I do this I get the message "Volume group "gluster_vg1" not found. Cannot process volume group gluster_vg1". I also tried the command the way you specified with just the LV and get the same results. > > I had placed the system in Global maintenance mode prior to the reboot. Upon reboot I got the messages about the various gluster volumes not being able to be mounted because of timeout issues. That is what started my OP. I think we are both thinking along the same lines regarding the issue. I think the question is how do you fix a volume that the system won't mount? It does seem likely that the thinpool needs to be repaired but what do you do if you can't even perform the first step in the procedure? > > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/2X73CAASB4UCO…

Re: How should ovirt-engine be repaired if it is hung up
by Strahil 30 Sep '19

1. Open VNC console and check the situation. Just like any other VM. 2. You can get the config via checking the vdsm log on the host where the system has started properly last time (as current situation is bad, check previous power up event). You can save the xml and use that to define the VM in virsh, but you also need to define ovirtmgmt network -> check in the web , as I don't have access to my systems right now. If virsh complaints about the disks - check that the storage domains' link is properly set to your storage.

Can you suffer downtime ? You can try something like this (I'm improvising): Set to global maintenance (either via UI or hosted-engine --set-maintenance --mode=global) Stop the engine. Stop ovirt-ha-agent ovirt-ha-broker vdsmd supervdsmd sanlock glusterd. Stop all gluster processes via thr script in /usr/share/gluster*..../something-named-kill Disable all LVs in the vg via: lvchange -an LV If it doesn't work try disabling the VG: vgchange -an VG and then enabling it again: vgchange -ay VG Last try to repair the thinpool via: lvchange --repair VG/thinpool Last disable the VG and give the system a reboot to verify everything works.

I don't think this is a replicated volume (though I could be wrong) I built a single node hyperconverged hypervisor. I was reviewing my gdeploy file from when I originally built the system.

Hello guys, I am being unable to put a host from a two nodes cluster into maintenance mode in order to remove it from the cluster afterwards.

If it's a replicated volume - then you can safely rebuild your bricks and don't even tryhto repair. There is no guarantee that the issue will not reoccur.
