oVirt 4.5.1 Hyperconverge Gluster install fails
by david.lennox＠frontlinedigital.com.au 18 Jul '22

18 Jul '22

Hello all, I am hoping someone can help me with a oVirt installation that has just gotten the better of me after weeks of trying. After setting up ssh-keys and making sure each host is known to the primary host (sr-svr04), I go though Cockpit and "Configure Gluster storage and oVirt hosted engine", enter all of the details with <host>.san.lennoxconsulting.com.au for the storage network FQDN and <host>.core.lennoxconsulting.com.au for the public interfaces. Connectivity on each of the VLAN's test out as basically working (everything is pingable and ssh connections work) and the hosts are generally usable on the network. But the install ultimately dies with the following ansible error: ----------- gluster-deployment.log --------- : : TASK [gluster.infra/roles/backend_setup : Create volume groups] **************** task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vg_create.yml:63 failed: [sr-svr04.san.lennoxconsulting.com.au] (item={'key': 'gluster_vg_sdb', 'value': [{'vgname': 'gluster_vg_sdb', 'pvname': '/dev/sdb'}]}) => {"ansible_loop_var": "item", "changed": true, "cmd": ["vgcreate", "--dataalignment", "1536K", "-s", "1536K", "gluster_vg_sdb", "/dev/sdb"], "delta": "0:00:00.058528", "end": "2022-07-16 16:18:37.018563", "item": {"key": "gluster_vg_sdb", "value": [{"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}]}, "msg": "non-zero return code", "rc": 5, "start": "2022-07-16 16:18:36.960035", "stderr": " A volume group called gluster_vg_sdb already exists.", "stderr_lines": [" A volume group called gluster_vg_sdb already exists."], "stdout": "", "stdout_lines": []} failed: [sr-svr05.san.lennoxconsulting.com.au] (item={'key': 'gluster_vg_sdb', 'value': [{'vgname': 'gluster_vg_sdb', 'pvname': '/dev/sdb'}]}) => {"ansible_loop_var": "item", "changed": true, "cmd": ["vgcreate", "--dataalignment", "1536K", "-s", "1536K", "gluster_vg_sdb", "/dev/sdb"], "delta": "0:00:00.057186", "end": "2022-07-16 16:18:37.784063", "item": {"key": "gluster_vg_sdb", "value": [{"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}]}, "msg": "non-zero return code", "rc": 5, "start": "2022-07-16 16:18:37.726877", "stderr": " A volume group called gluster_vg_sdb already exists.", "stderr_lines": [" A volume group called gluster_vg_sdb already exists."], "stdout": "", "stdout_lines": []} failed: [sr-svr06.san.lennoxconsulting.com.au] (item={'key': 'gluster_vg_sdb', 'value': [{'vgname': 'gluster_vg_sdb', 'pvname': '/dev/sdb'}]}) => {"ansible_loop_var": "item", "changed": true, "cmd": ["vgcreate", "--dataalignment", "1536K", "-s", "1536K", "gluster_vg_sdb", "/dev/sdb"], "delta": "0:00:00.062212", "end": "2022-07-16 16:18:37.250371", "item": {"key": "gluster_vg_sdb", "value": [{"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}]}, "msg": "non-zero return code", "rc": 5, "start": "2022-07-16 16:18:37.188159", "stderr": " A volume group called gluster_vg_sdb already exists.", "stderr_lines": [" A volume group called gluster_vg_sdb already exists."], "stdout": "", "stdout_lines": []} NO MORE HOSTS LEFT ************************************************************* NO MORE HOSTS LEFT ************************************************************* PLAY RECAP ********************************************************************* sr-svr04.san.lennoxconsulting.com.au : ok=32 changed=13 unreachable=0 failed=1 skipped=27 rescued=0 ignored=1 sr-svr05.san.lennoxconsulting.com.au : ok=31 changed=12 unreachable=0 failed=1 skipped=27 rescued=0 ignored=1 sr-svr06.san.lennoxconsulting.com.au : ok=31 changed=12 unreachable=0 failed=1 skipped=27 rescued=0 ignored=1 ----------- gluster-deployment.log --------- A "gluster v status" gives me no volumes present and that is where I am stuck!

Engine storage Domain path change
by michael＠wiswm.com 17 Jul '22

17 Jul '22

Hello I installed oVirt on 3 servers(hv1,hv2,hv3) with Self Hosted Engine couple years ago. Gluster is used as storage for VMs. The engine has its own storage volume. Then I added 3 more servers(hv4,hv5,hv6). Now I would like to replace the first 3 servers. I added 3 more servers(hv7,hv8,hv9). I created new gluster volumes on hv7-hv9, moved disks from old volumes. Now the question is how to migrate engine storage? I decided to do it on Gluster level by replacing each of the brick from the old servers(hv1-hv3) with new ones (hv7-hv9). I successfully replaced bricks from hv1 and hv2 to hv7 and hv8. InoVirt engine storage Domain is created with the path hv3:/engine. I am afraid to replace hv3 brick with hv9, to not break the HostedEngine VM. To change storage Domain path I need to move it to Maintenance, but it will unmount it from all the hosts and HostedEngine will stop working. Is there any otherway to change a storage Domain path? I already changed storage value in /etc/ovirt-hosted-engine/hosted-engine.conf. I did something like this: # on hv7 hosted-engine --vm-shutdown # on all hosts systemctl stop ovirt-ha-agent systemctl stop ovirt-ha-broker hosted-engine --disconnect-storage sed -i 's/hv3/hv7/g' /etc/ovirt-hosted-engine/hosted-engine.conf hosted-engine --connect-storage systemctl restart ovirt-ha-broker systemctl status ovirt-ha-broker systemctl restart ovirt-ha-agent # on hv7 hosted-engine --vm-start and now the Hosted Engine is up and running and Gluster engine volume is mounted like hv7:/engine So the main question remains - how to change the engine storage Domain path?

Stuck in Manager upgrade. Can't set Cluster to maintenance mode.
by johannes.lutz＠diamontech.de 16 Jul '22

16 Jul '22

Hi Folks, like many others, the ovirt hosted engine certificates expired on my installation. We tried to follow this knowledge base article: https://access.redhat.com/solutions/6865861 I set the host which runs the hosted engine via the "hosted-engine --set-maintenance --mode=global" command into the global maintenance mode. Then i try to execute the "engine-setup --offline" command. There we anwser all questions and the script recognizes the expired certificates. But when we try to execute the last step it aborts with following error message. Output of engine-setup --offline: [WARNING] Failed to read or parse '/etc/pki/ovirt-engine/keys/apache.p12' Perhaps it was changed since last Setup. Error was: Mac verify error: invalid password? One or more of the certificates should be renewed, because they expire soon, or include an invalid expiry date, or they were created with validity period longer than 398 days, or do not include the subjectAltName extension, which can cause them to be rejected by recent browsers and up to date hosts. See https://www.ovirt.org/develop/release-management/features/infra/pki-renew/ for more details. Renew certificates? (Yes, No) [No]: Yes --== APACHE CONFIGURATION ==-- --== SYSTEM CONFIGURATION ==-- --== MISC CONFIGURATION ==-- --== END OF CONFIGURATION ==-- [ INFO ] Stage: Setup validation During execution engine service will be stopped (OK, Cancel) [OK]: Ok [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data. [ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine setup detected, but Global Maintenance is not set. [ INFO ] Stage: Clean up Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20220701205812-yu1osl.log [ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20220701205843-setup.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Execution of setup failed Any ideas how to get the hosted engine into global maintenance mode? Thanks for your help in advance! Best Regard J. Lutz

Hello List, I successfully deployed a fresh hosted-engine, but I'm not able to login to Administration-Portal. I'm perferctly sure about the password I had to type multiple times.... I'm running ovirt-node-ng-4.5.1-0.20220622.0 and deployed engine via cli-based ovirt-hosted-engine-setup. Neither "admin" nor "admin@internal" are working (A profile cannot be choosen as in earlier versions). I can login to the monitoring part (grafana !) and also Cockpit but not Administration-Portal nor VM-Portal. I can ssh into the engine and lookup the user-database which has the user. root@engine02 ~]# ovirt-aaa-jdbc-tool query --what=user Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false -- User admin(2be16cf0-5eb7-4b0e-923e-7bdc7bc2aa6f) -- Namespace: * Name: admin ID: 2be16cf0-5eb7-4b0e-923e-7bdc7bc2aa6f Display Name: Email: root@localhost First Name: admin Last Name: Department: Title: Description: Account Disabled: false Account Locked: false Account Unlocked At: 1970-01-01 00:00:00Z Account Valid From: 2022-07-15 18:23:47Z Account Valid To: 2222-07-15 18:23:47Z Account Without Password: false Last successful Login At: 1970-01-01 00:00:00Z Last unsuccessful Login At: 1970-01-01 00:00:00Z Password Valid To: 2222-05-28 18:23:49Z However no groups by default ???

Seeking best performance on oVirt cluster
by David Johnson 14 Jul '22

14 Jul '22

Good morning all, I am trying to get the best performance out of my cluster possible, Here are the details of what I have now: Ovirt version: 4.4.10.7-1.el8 Bare metal for the ovirt engine two hosts TrueNAS cluster storage 1 NFS share 3 vdevs, 6 drives in raidz2 in each vdev 2 nvme drives for silog Storage network is 10 GBit all static IP addresses Tonight, I built a new VM from a template. It had 5 attached disks totalling 100 GB. It took 30 minutes to deploy the new VM from the template. Global utilization was 9%. The SPM has 50% of its memory free and never showed more than 12% network utilization 62 out of 65 TB are available on the newly created NFS backing store (no fragmentation). The TureNAS system is probably overprovisioned for our use. There were peak throughputs of up to 4 GBytes/second (on a 10 GBit network), but overall throughput on the NAS and the network were low. ARC hits were 95 to 100% L2 hits were 0 to 70% Here's the NFS usage stats: [image: image.png] I believe the first peak is where the silog buffered the initial burst of instructions, followed by sustained IO as the VM volumes were built in parallel, and then finally tapering off to the one 50 GB volume that took 40 minutes to copy. The indications of the NFS stats graph are that the network performance is just fine. Here are the disk IO stats covering the same time frame, plus a bit before to show a spike IO: [image: image.png] The spike at 2250 (10 minutes before I started building my VM) shows that the spinners actually hit write speed of almost 20 MBytes per second briefly, then settled in at a sustained 3 to 4 MBytes per second. The silog absorbs several spikes, but remains mostly idle, with activity measured in kilobytes per second. The HGST HUS726060AL5210 drives boast a spike throughput of 12 GB/S, and sustained throughput of 227 Mbps. ------ Now to the questions: 1. Am I asking the on the right list? Does this look like something where tuning ovirt might make a difference, or is this more likely a configuration issue with my storage appliances? 2. Am I expecting too much? Is this well within the bounds of acceptable (expected) performance? 3. How would I go about identifying the bottleneck, should I need to dig deeper? Thanks, David Johnson

Greetings, Is it possible with oVirt to import existing VMs where the underlying storage is on raw iSCSI luns and to keep them on those luns? The historical scenario is that we have Virtual farms in multiple sites managed by an ancient Orchestration tool that does not support modern OS's as the hypervisor. - In each site, there are clusters of hypervisors/Hosts that have visibility to the same iSCSI luns. - Each VM has it's own set of iscsi luns that are totally dedicated to that VM - Each VM is using LVM to manage the disk - Each Host has LVM filtering configured to NOT manage the VM's iscsi luns - The VMs can be live migrated from any Hypervisor within the cluster to any other Hypervisor in that same cluster We are attempting to bring this existing environment into oVirt without replacing the storage model. Is there any documentation that will serve as a guide for this scenario? In a lab environment, we have successfully - Added 2 hypervisors (hosts) and oVirt can see their VMs as external-ovtest1 and external-ovtest2 - Removed the LVM filtering on the hosts - Created a storage domain that is able to see the iscsi luns, but we have not yet done the 'add' of each lun Is it possible to import these luns as raw block devices without LVM being layered on top of them? Is it required to actually import the luns into a storage domain, or can the VM's still be imported if all luns are visible on all hosts in the cluster? In the grand scheme of things, are we trying to do something that is not possible with oVirt? If it is possible, we would greatly appreciate tips, pointers, links to docs etc that will help us migrate this environment to oVirt. Thanks in Advance - S

Q: Instaling Ovirt Engine 4.4.10 on Clean CentOS 8 Stream

Hi, Since I run into a lot of problems upgrading 4.4.7 to 4.4.10, is it OK to install clean CentOS-Stream-8-x86_64-20220712-dvd1.iso and restore from backup? 4.4.10 release long before Stream 20220712, may I run again into similar problems, or I need to use earlier snapshot of Stream 8 ? I use dedicated engine PC, not hosted engine. Thanks in advance for any suggestion(s) Andrei
