basic infra and glusterfs sizing question
by Jiří Sléžka 04 Jun '20

04 Jun '20

Hello, I am just curious if basic gluster HCI layout which is suggested in cockpit has some deeper meaning. There are suggested 3 volumes * engine - it is clear, it is the volume where engine vm is running. When this vm is 51GB big how small could this volume be? I have 1TB SSD storage and I would like utilize it as much as possible. Could I create this volume as small as this vm is? Is it safe for example for future upgrades? * vmstore - it make sense it is a space for all other vms running in oVirt. Right? * data - which purpose has this volume? other data like for example ISOs? Direct disks? Another infra question... or maybe request for comment I have small amount of public ipv4 addresses in my housing (but I have own switches there so I can create vlans and separate internal traffic). I can access only these public ipv4 addresses directly. I would like to conserve these addressess as much as possible so what is the best approach in your opinion? * Install all hosts and HE with management network on private addressess * have small router (hw appliance with for example LEDE) which will utilize one ipv4 address and will do NAT and vpn for accessing my internals vlans. + looks like simple approach to me - single point of failure in this router (not really - just in case oVirt is badly broken and I need to access internal vlans to recover it) * have this router as virtual appliance inside oVirt (something like pfSense for example) + no need hw router + not sure but I could probably configure vrrp redundancy - still single point of failure like in first case * any other approach? Could ovn help here somehow? * Install all hosts and HE with public addresses :-) + access to all hosts directly - 3 node HCI cluster uses 4 public ip addressess Thanks for your opinions Cheers, Jiri

Ovirt 4.4 HC gluster issues on new CentOS 8 node (cluster still in 4.3 compatibility level)
by jillian.morgan＠primordial.ca 04 Jun '20

04 Jun '20

I've successfully migrated to a new 4.4 engine, now managing the older 4.3 (CentOS 7) nodes. So far so good there. I installed a new CentOS 8 node w/ 4.4, joined it to the Gluster peer group, and it can see all of the volumes, but the node won't go into Online state in the engine because of apparent gluster-related VDSM errors: Status of host butter was set to NonOperational. Gluster command [<UNKNOWN>] failed on server <UNKNOWN>. VDSM butter command ManageGlusterServiceVDS failed: The method does not exist or is not available: {'method': 'GlusterService.action'} I haven't been able to find anything in the VDSM or Engine logs that give me any hint as to what's going on (besides just repeating that the "GlusterSerice.action" method doesn't exist). Anybody know what I'm missing, or have hints on where to dig to debug further?

This update is the first in a series of stabilization updates to the 4.4 series. 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. Some of the features included in oVirt 4.4.1 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed.

So, where do i get this information from? or should i be using a different method to log into a vm? This goes for all of the VMs available by default. can someone please help me with this? thanks

4.4 regression: engine-setup fails if admin password in answerfile contains a "%"
by Stephen Panicho 03 Jun '20

03 Jun '20

I encountered this error when deploying the Hosted Engine via Cockpit: [ INFO ] TASK [ovirt.engine-setup : Run engine-setup with answerfile] [ ERROR ] fatal: [localhost -> engine.ovirt.trashnet.xyz]: FAILED! => {"changed": true, "cmd": ["engine-setup", "--accept-defaults", "--config-append=/root/ovirt-engine-answers"], "delta": "0:00:01.396490", "end": "2020-05-22 18:32:41.965984", "msg": "non-zero return code", "rc": 1, "start": "2020-05-22 18:32:40.569494", "stderr": "", "stderr_lines": [], "stdout": "[ INFO ] Stage: Initializing\n[ ERROR ] Failed to execute stage 'Initializing': '%' must be followed by '%' or '(', found: '%JUUj'\n[ INFO ] Stage: Clean up\n Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20200522183241-c7d1kh.log\n[ ERROR ] Failed to execute stage 'Clean up': 'NoneType' object has no attribute 'cleanup'\n[ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20200522183241-setup.conf'\n[ INFO ] Stage: Pre-termination\n[ INFO ] Stage: Termination\n[ ERROR ] Execution of setup failed", "stdout_lines": ["[ INFO ] Stage: Initializing", "[ ERROR ] Failed to execute stage 'Initializing': '%' must be followed by '%' or '(', found: '%JUUj'", "[ INFO ] Stage: Clean up", " Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20200522183241-c7d1kh.log", "[ ERROR ] Failed to execute stage 'Clean up': 'NoneType' object has no attribute 'cleanup'", "[ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20200522183241-setup.conf'", "[ INFO ] Stage: Pre-termination", "[ INFO ] Stage: Termination", "[ ERROR ] Execution of setup failed"]} The important bit is this: Failed to execute stage 'Initializing': '%' must be followed by '%' or '(', found: '%JUUj'" Hey! Those are the last few characters of the admin password. Note that I don't mean the root password to the VM, but the one for the "admin" user of the web interface. I added some debug lines to the Ansible play to see the answerfile that was being generated. OVESETUP_CONFIG/adminPassword=str:&6&yGfcWf#b%JUUj Apparently engine-setup can no longer handle an answerfile with a "%" character in it. This same password worked in 4.3. Once I changed the admin password, installation progressed normally.

Import VM from export domain using oVirt-4.4
by Joop 03 Jun '20

03 Jun '20

Hi All, I'm testing a shiny new oVirt-4.4.02, selfhosted engine HCI gluster, and found a problem when importing my VMs from an export domain. Import is OK but can't start the VM due to the fact that the BIOS is set to Legacy. Manually setting the BIOS type to Cluster Default, through VM properties, will let the VM start. I couldn't find anything about it in the ReleaseNotes As a side note: using gluster still doesn't install gluster-ansible-roles and glusterfs-server and vdsm-gluster or checks for its existance. See also another user who reported problems due to the latter not being installed, had the same experience. Regards, Joop

Recuring error in the Administration Portal
by Krist van Besien 03 Jun '20

03 Jun '20

When using the Administration Portal after a while I start to get errors like this: 'Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'isEval' of undefined Please have your administrator check the UI logs' 'Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : null is not an object (evaluating 'b.b.b.a') Please have your administrator check the UI logs' These errors appear when I use Brave, but also appear after a while in Firefox, Chrome or Safari.

What is going on? A bug? A misconfiguration? Database corruption? This is an ovirt 4.4 cluster I setup on Centos 8. The cluster uses gluster storage, and was setup only a few days ago.
