[Help] The engine is not stable on HostedEngine with GlusterFS Herperverged deployment
by mengz.you＠outlook.com 20 Apr '21

20 Apr '21

Hi, I deployed a oVirt (4.3.10) cluster with HostedEngine and GlusterFS volumes (engine, vmstore, data), the glusterfs cluster on node1/node2/node3, and the engine vm can be running on those 3 nodes. Then I added a 4th nodes into cluster. But, when I operates on Eninge Web Portal, it's always reports 503 error, then I checked `hsoted-engine --vm-status`, see below: ``` [root@vhost1 ~]# hosted-engine –vm-status –== Host vhost1.yhmk.lan (id: 1) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost1.<span style=”background-color: rgb(255, 255, 255); color: rgb(51, 51, 51);”>alatest</span>.lan Host ID : 1 Engine status : {“reason”: “bad vm status”, “health”: “bad”, “vm”: “down_unexpected”, “detail”: “Down”} Score : 0 stopped : False Local maintenance : False crc32 : 1f25baff local_conf_timestamp : 1253650 Host timestamp : 1253649 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1253649 (Thu Apr 8 08:05:48 2021) host-id=1 score=0 vm_conf_refresh_time=1253650 (Thu Apr 8 08:05:48 2021) conf_on_shared_storage=True maintenance=False state=EngineUnexpectedlyDown stopped=False timeout=Thu Jan 15 20:23:29 1970 –== Host vhost2.yhmk.lan (id: 2) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost2.<span style=”background-color: rgb(255, 255, 255); color: rgb(51, 51, 51);”>alatest</span>.lan Host ID : 2 Engine status : {“reason”: “vm not running on this host”, “health”: “bad”, “vm”: “down_unexpected”, “detail”: “unknown”} Score : 3400 stopped : False Local maintenance : False crc32 : 539fc30c local_conf_timestamp : 1253343 Host timestamp : 1253343 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1253343 (Thu Apr 8 08:05:46 2021) host-id=2 score=3400 vm_conf_refresh_time=1253343 (Thu Apr 8 08:05:46 2021) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False –== Host vhost3.yhmk.lan (id: 3) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost3.alatest.lan Host ID : 3 Engine status : {“reason”: “bad vm status”, “health”: “bad”, “vm”: “up”, “detail”: “Powering up”} Score : 3400 stopped : False Local maintenance : False crc32 : 4072e0b8 local_conf_timestamp : 1252345 Host timestamp : 1252345 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1252345 (Thu Apr 8 08:05:42 2021) host-id=3 score=3400 vm_conf_refresh_time=1252345 (Thu Apr 8 08:05:42 2021) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False ``` Then, wait a moment, can access web portal again, and check the hosts status, alway reports one or more hosts with label `unavaiable as HA score`, but it will dispear later. And I found, sometimes the engine vm will migrated to another nodes whill this problem occur. So, seems the HostedEngine is not stable, always occur this problem, could you please help me with this ? Thanks!

Re: ovirt-hosted-engine-cleanup
by Thomas Hoberg 20 Apr '21

ovirt-hosted-engine-cleanup will only operate on the host you run it on. In a cluster that might have side-effects, but as a rule it will try to undo all configuration settings that had a Linux host become an HCI member or just a host under oVirt management. While the GUI will try to do the same with Ansible only, the script seems to do a little more and be more thorough. My guess is that it's somewhat of a leftover from the older 'all scripts' legacy of oVirt, before they re-engineered much of it to fit Ansible. It's not perfect, however. I have come across things that it would not undo, and that were extremely difficult to find (a really clean re-install would then help). There was an issue around keys and certificates for KVM that I only remember as a nightmare and more recently I had an issue with it's ansible scripts inserting an LVM device filter specific for a UID that the HCI setup wizard had created, which then precluded it ever working again after running the *cleanup scripts. All I got was "device excluded by a filter" and only much later I found the added line in /etc/lvm.conf not undone, which caused this nail-biter. But generally that message "Is hosted engine setup finished?" mostly indicates that the four major daemons for HCI still have issues. It all starts with glusterd: If you just added a host in HCI with storage, that would like to be properly healed. AFAIK that doesn't actually preclude already using the machine to host VMs, but in the interest of keeping your head clear, I'd suggest concentrating on getting the storage all clean, with gluster happily showing connectivity all around (gluster volume status all etc.) and 'gluster volume heal <volume> [info]' giving good results. Then you need to check on the services ovirt-ha-broker and ovirt-ha-agent as well as vdsmd via 'servicectl status <servicename>' to see what they are complaining about. I typically restart them in this order to iron out the bumps. As long as you give them a bit of time, restarting them periodically doesn't seem to do any harm, but helps them recover from hangs. And then you simply need patience: Things don't happen immediately in oVirt, because few commands ever intervene into anything directly. Instead they set flags here and there which then a myriad of interlocking state machine gears will pick up and respond to, to do things in the proper order and by avoiding the race conditions manual intervention can so easily cause. Even the fastest systems won't give results in seconds. So have a coffee, better yet, some herbal tea, and then look again. There is a good chance oVirt will eventually sort it out (but restarting those daemons really can help things along, as will looking at those error messages and their potential cause).

Introduction & general question about oVirt
by Nicolas Kovacs 20 Apr '21

20 Apr '21

Hi, I'm a 53-year old Austrian living in Montpezat, a small village in South France. I'm an IT professional with a focus on Linux and free software, and I've been a Linux user since Slackware 7.1. I'm doing web & mail hosting for myself and several small structures like our local school and a handful of local companies. Up until recently these hostings have happened on "bare metal" root servers using CentOS 7. One main server is hosting most of the stuff: WordPress sites, one OwnCloud instance, Dolibarr management software, GEPI learning platform, Postfix/Dovecot mail server, Roundcube webmail, etc. This setup has become increasingly problematic to manage, since applications have more and more specific requirements, like different versions of PHP and corresponding modules. So I decided to split everything up nicely into a series of virtual machines, each one with a nicely tailored setup. I have a couple of sandbox servers, one public and one local, running Oracle Linux 7 (a RHEL clone like CentOS). I played around with it, and KVM-based virtualization already works quite nicely. While looking for documentation, I stumbled over oVirt, which I didn't even know existed until last week. Before I dive head first into it, I'd be curious to know a few general things. 1. Would it be overkill for a small structure like mine? 2. Will I be able to do HA on a series of modest KVM-capable root servers even if they are located in different datacenters across different countries? 3. One problem I couldn't resolve using a bone-headed keep-it-simple KVM setup is backup. For my bare-metal servers I've been using incremental backups using Rsnapshot for years. Here's a blog article I wrote on the subject: https://blog.microlinux.fr/rsnapshot-centos-7/ Unfortunately I can't use this approach with huge QCOW images, at least not without jumping through burning loops. Is there an easy way to perform remote incremental backups with oVirt? BTW, I took a peek at Proxmox and Ceph, but I admit I'm a die-hard RHEL-clone user.

Upgrading single host ovirt "clusters" to v4.5 via command line?
by Gilboa Davara 19 Apr '21

19 Apr '21

Hello all, As the title suggests I have a couple of single-host hyper converged setups, mostly used for testing. As I cannot use the GUI cluster upgrade method on a single host (it requires me to reboot the host, which will require me to shutdown the hosted engine), is there any method to upgrade the cluster / data-center via command line in maintenance=global mode? Beyond that, can I use the same method on my production setups? (multi-node, gluster based setups). Thanks, Gilboa

Why and when does oVirt make a compute host part of the HCI Gluster?
by Thomas Hoberg 19 Apr '21

19 Apr '21

My understanding is that in a HCI environment, the storage nodes should be rather static, but that the pure compute nodes, can be much more dynamic or opportunistic: actually those should/could even be switched off and restarted as part of oVirt's resource optimization. The 'pure compute' nodes fall into two major categories, a) those who can run the management engine, b) those who can't. What I don't quite understand is why both types seem to be made 'gluster peers', when they don't contribute storage bricks: shouldn't they just be able to mount Gluster volumes? The reason for my concern is that I actually want to manage these computing hosts with much more freedom. I may have them join and take on workloads, or not and I may want to shut them down. To my irritation I sometimes even see these 'missing' hosts being considered for quorum decisions or being listed e.g. when I do a 'gluster volume engine status'. I find hosts there, that definitely are not contributing bricks to 'engine' (or any other volume). Then I'm not even sure I have consistent behavior when I remove hosts from oVirt: I'd swear that quite a few remain as Gluster peers, even if they are completely invisible from the oVirt GUI (while hosted-engine --vm-status will still list them). So what's the theory here and would it be a bug if removed hosts remain gluster members?

Expand gluster volumes
by David White 19 Apr '21

19 Apr '21

Is it possible to expand an existing gluster volume? I have a hyperconverged environment, and have enough space right now, but I'm going to have to significantly over-provision my environment. The vast majority of our customers are using a small fraction of the amount of space that they are technically allocated, but we still need to make that space available to them. As a result, I'd like to plan ahead, and go ahead and have a plan to add storage later down the road. I'd like to plan to shut down each server in the cluster (individually, not at once), add storage, and then bring them back online. Once all 3 are back online with the additional storage, I'd like to expand the gluster volume to use the additional space. Is that possible? How? Sent with ProtonMail Secure Email.

Ovirt and gluster 9 volume
by eevans＠digitaldatatechs.com 17 Apr '21

17 Apr '21

My setup is 3 Centos 7 servers hyper-converged with a 4th stand alone engine server. My issue is Ovirt is reading the cluster disk as 49GiB instead of 5.5 TB is should be. One server has a 928 GB raid 5 volume, the second has a 7,7 TB raid 10 volume and the third has a 5.5 TB raid 10 volume. How is Ovirt translating this to 49 GiB?? Here is a link to the screen shots for verification. https://1drv.ms/u/s!AvgvEzKKSZHbhLIrRBvQRLmoZOeEyw?e=rO83vw Logs look good unless I missed something. Any help is appreciated. Eric

Remote VNC
by David White 17 Apr '21

17 Apr '21

I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/message/KT3B6N3UZ3DS3… In short, I have ssh to the datacenter. I can ssh to a public IP address with the "-D 8080" option to forward local port 8080 act as a SOCKS proxy. I then edit my local computer's proxy settings and set the SOCKS host to 8080. So this is a system-wide change. I'm not setting the SOCKS proxy in the browser preferences. After I do all that, I'm able to use my browser to get to the engine web UI, and I'm able to login. However, the console for each VM isn't working. In the thread I linked to above, Alan says to do this: 2. SSH to the hypervisor tunneling a local port to that remote console port. 3. Click on the console link in the Engine and locally save the vv file.4. Edit the vv file; change host to localhost and port to whichever port you configured for the local side of the tunnel. Question: I'm confused why I need to tunnel a local port to the remote console port, if I'm already tunneling port 8080 to the host. Question: I don't have much experience with ssh port forwarding. If I already have the SOCKS proxy working, how, exactly, would I accomplish step #2? With the 8080 socks proxy working, I've now tried to run this command: ssh -L 5902:127.0.0.1:5901 username@ovirt-host-ip And in this case, I'm "assuming" that 5902 is going to listen on my local computer, and that I need to edit the vv file to connect to 127.0.0.1, port 5902. That's not working. Maybe I don't understand how SOCKS proxies work, but I was hoping / under the impression that all of my network traffic would go through the ssh tunnel on port 8080, and that vnc would work at that point.

Odd question: changing network MTU
by Chris Adams 16 Apr '21

16 Apr '21

I have an oVirt 4.3 cluster, running in one location. I have to move it to another location. I've got a couple of 1G links between the sites, and that's enough bandwidth for this (at least temporarily), but... I have my iSCSI networks defined with a MTU of 9000, and it turns out the site-to-site links only allow 1500 (and these links are going away after this is done, so I don't think either carrier would be interested in changing things to support larger). Because of that, the storage won't connect up. I tried going "under the hood" and setting a firewalld rule to force the MSS to a smaller value, but that didn't seem to get it. What happens if I change the MTU of an active iSCSI network in oVirt? I could just go manually change it on each node's iSCSI interfaces, but I'm not sure if oVirt might change it back. Also, I'm not sure what would happen to open iSCSI TCP connections (would they reduce gracefully). Any other suggestions/tips/etc.? I'd like to make this as transparent as possible, so was hoping to live-migrate VMs and storage. -- Chris Adams <cma(a)cmadams.net>

ovirt-hosted-engine-cleanup
by Marko Vrgotic 16 Apr '21

16 Apr '21

Dear oVirt, I have three HE Hosts. Upon upgrade from 4.3.5 to 4.3.10 the Hosted Engine did not start anymore on Host2, but working just fine on Host1 and Host3. I tried to Undeploy – Deploy on Host2 but I noticed that hosted-engine.conf contains only ca path and host id. It looks like either Undeploy properly or Deploy is failing due to reason I am unable to find in the logs. When checking the hosted-engine –vm-status, even though undeployed, the output was still containing Host2 in the list. Than I cleaned metadata on the Host1 and 3 for Host2 and at that point it was forgotten. After that I tried adding the Host2 back to HE pool, first installed the Host2 with fresh OS and than added it to Hosts pool with HostedEngine DEPLOY option. Result was the same. The VDSM on the Host2 was showing ERROR: “2021-04-16 06:47:30,422+0000 ERROR (periodic/3) [root] failed to retrieve Hosted Engine HA score '[Errno 2] No such file or directory'Is the Hosted Engine setup finished? (api:196)” The broker is showing the error: “MainThread::WARNING::2021-04-16 06:47:27,514::storage_broker::97::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: 'metadata_image_UUID can't be 'None' Atm, I am thinking of executing the /usr/sbin/ovirt-hosted-engine-cleanup but its effect is not clear to me. Is it going to cleanup any HE deploy remains from the Host its executed on, or its going to cleanup the other two Hosts, rendering my platfrom offline? I have been reading through https://www.ovirt.org/images/Hosted-Engine-4.3-deep-dive.pdf but its effect is not clear. I would have tested it already but this issue is on our production platform, so I need some experts input before taking further action.

Moving hosted engine storage
by Chris Adams 16 Apr '21

16 Apr '21

I'm moving a 4.3 cluster to new storage, and I'm down to the hosted engine. I am reading the following: https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_… https://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-engi… https://lists.ovirt.org/pipermail/users/2017-January/078739.html The last mentions a couple of options added to engine-backup to filter out the old hosted engine parts, but where do I use them? It looks like they only apply during restore, but from the last time I rebuilt the engine (mvoing from CentOS 6 to CentOS 7), I thought I just provided the backup file to hosted-engine --deploy and it handled the restore. Is there a way to pass those options to hosted-engine --deploy, or should I do like the example and just deploy a brand new engine, then log in and manually apply the backup (and filter options) then? Just trying to make sure I understand current (well, current for 4.3) best practice for replacing the hosted engine's storage array (iSCSI in this case, if that matters). -- Chris Adams <cma(a)cmadams.net>

I was able to get the other hosts to forget about this one, by running hosted-engine –clean-metadate –host-id=2 Now I would like to try to add the host back to HE pool, but I have a question: “Is there a time I should wait, between cleaning metadata and re-adding the host?” Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

If they are not, most likely there is some corruption somewhere - in the engine db or shared storage.

In -ha logs? Please also note that 4.3 is EOL. The deploy process was completely rewritten in 4.4 (in ansible, previous was python), although should in principle behave similarly - so if your data is corrupted, upgrade to 4.4 probably won't fix it.

I was able to get the other hosts to forget about this one, by running hosted-engine –clean-metadate –host-id=2 Now I would like to try to add the host back to HE pool, but I have a question: “Is there a time I should wait, between cleaning metadata and re-adding the host?” Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

[ANN] oVirt 4.4.6 Fourth Release Candidate is now available for testing
by Sandro Bonazzola 15 Apr '21

15 Apr '21

oVirt 4.4.6 Fourth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.6 Fourth Release Candidate for testing, as of April 15th, 2021. This update is the sixth in a series of stabilization updates to the 4.4 series. Rebase on CentOS Stream Starting with oVirt 4.4.6 RC4 both oVirt Node and oVirt Engine Appliance are based on CentOS Stream. You can still install oVirt 4.4.6 on Red Hat Enterprise Linux, CentOS Linux or equivalent. Please note that when 4.4.6 will be released as generally available, existing oVirt Nodes updating to 4.4.6 will automatically be based on CentOS Stream. Help testing this release candidate will help ensuring a smooth experience for your main installation. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later 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 4.4.6 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 4.4.6 (redeploy in case of already being on 4.4.6). 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. Known issues: - Bug 1946095 <https://bugzilla.redhat.com/show_bug.cgi?id=1946095> - "No valid network interface has been found" when starting HE deployment via cockpit - For testing purposes you can use the command line <https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_us…> 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 8.3 or newer * CentOS 8 Stream * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS 8 Stream * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS 8 Stream (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.
