If they are not, most likely there is some corruption somewhere - in the engine db or shared storage. You might want to skim this for a general rather-low-level overview: https://www.ovirt.org/images/Hosted-Engine-4.3-deep-dive.pdf Do you see no errors on your other hosts? 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.

Ovirt with Oracle Linux 8.3 & Cockpit - Direct Luns
by hansontodd＠gmail.com 14 Apr '21

14 Apr '21

Is Ovirt compatible with Oracle Linux 8.3? I have KVM & Cockpit running on Oracle Linux 8.3 but don't see a way to map direct luns (like RDM's) to the VM in the Cockpit interface. Do I need to move back to Centos 7.x or RHEL 7.x with Ovirt to be able to use direct luns? Can Ovirt and Cockpit coexist?

Add Gluster only nodes?
by mathias.westerlund＠wdmab.se 14 Apr '21

14 Apr '21

Hello! We have a medium sized hyper converged setup where we run SSD based bricks on the hosts. we also have an iscsi storage domain towards some spinner boxes for slow bulk storage but now we would like to add an medium sized storage option where mid sized requirements and mid level I/O requirements can exist. Our hyperconverged is NVME Our spinner is Sata. We now want to add an sata SSD storage option. We have some 25 slot hosts that are going to fill this usecase and we are now wondering, is there a way we can deploy gluster on these nodes using ovirt without giving them the VM role? Due to this storage being aimed towards things such as databases and other intensive (But not as intensive as our NVME layer) use cases we dont want there to be any VM load on these machines because of the pure number of bricks on the machines and the redhat best practice of 1 core per brick. Can i use cockpit/ovirt to deploy the above or do i have to set up an gluster cluster manually and then add it to ovirt???

New Setup - hosts - are not synchronized with their Logical Network configuration: ovirtmgmt.
by morgan cox 14 Apr '21

14 Apr '21

Hi After installing new hosts they show as status 'up'. however I get a warning such as Host ng2-ovirt-kvm4's following network(s) are not synchronized with their Logical Network configuration: ovirtmgmt. Which means ovirtmgmt is not working. I realise the issue is due to no network config for it - its set to DHCP and there is no server. The way I have setup the network on the hosts is (I used the ovirt-node 4.4.4 iso to install the nodes) /var/lib/vdsm/persistence/ ├── netconf -> /var/lib/vdsm/persistence/netconf.JkcBbtya └── netconf.JkcBbtya ├── bonds │ └── bond0 ├── devices └── nets ├── ovirtmgmt └── td-hv td-hv - is a bonded bridge + VLAN and has the network config with correct ip and where the firewall access is allowing the ports used for ovirt (see config below) Can I make the existing td-hv profile replace ovirtmgmt ? (i.e add ovirtmgmt functionality to existing network device td-hv) Or should I use the existing settings from td-hv and add them to ovirtmgmt and remove td-hv ? Config below - any advice would be great --- /etc/sysconfig/network-scripts/ifcfg-bond0.1700 BONDING_OPTS="mode=active-backup downdelay=0 miimon=100 updelay=0" TYPE=Bond BONDING_MASTER=yes NAME=bond0 UUID=5ab633aa-cd30-4ca8-9109-dbb4541f039b DEVICE=bond0 ONBOOT=yes HWADDR= MACADDR=3C:A8:2A:15:F6:12 MTU=1500 LLDP=no BRIDGE=ovirtmgmt --- --- [root@ng2-ovirt-kvm4 mcox]# cat /etc/sysconfig/network-scripts/ifcfg-bond0.1700 VLAN=yes TYPE=Vlan PHYSDEV=bond0 VLAN_ID=1700 REORDER_HDR=yes GVRP=no MVRP=no HWADDR= NAME=bond0.1700 UUID=e2b318e8-83af-4573-a637-fe20326f2c1a DEVICE=bond0.1700 ONBOOT=yes MTU=1500 LLDP=no BRIDGE=td-hv --- --- [root@ng2-ovirt-kvm4 mcox]# cat /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt STP=no TYPE=Bridge HWADDR= MTU=1500 PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=dhcp DEFROUTE=yes DHCP_CLIENT_ID=mac IPV4_DHCP_TIMEOUT=2147483647 IPV4_FAILURE_FATAL=no IPV6_DISABLED=yes IPV6INIT=no NAME=ovirtmgmt UUID=202586b0-ebe7-48ae-b316-e2cfd2dc4cc8 DEVICE=ovirtmgmt ONBOOT=yes AUTOCONNECT_SLAVES=yes LLDP=no ---

Need help recovering ovirt engine (was: New Management VLAN for hyperconverged cluster)
by David White 13 Apr '21

13 Apr '21

I was able to fix the connectivity issues between all 3 hosts. It turned out that I hadn't completely deleted the old vlan settings from the host. I re-ran "nmcli connection delete" on the old vlan. After that, I had to edit a network-scripts file and change/fix the bridge to use ifcfg-ovirtmgmt. After I did all that, the problematic host was accessible again. All 3 Gluster peers are now able to see each other and communicate over the management network. From the command line, I was then able to successfully run "hosted-engine --connect-storage" without errors. I was also able to then run "hosted-engine --vm-start". Unfortunately, the engine itself is still unstable, and when I access the web UI / oVirt Manager, it shows that all 3 hosts are inaccessible and down. I don't understand how the web UI is operational at all if the engine thinks that all 3 hosts are inaccessible. What's going on there? Although the initial problem was my own doing (I changed the management vlan), I'm deeply concerned with how unstable everything became - and has continued to be- ever since I lost connectivity to the 1 host. I thought the point of all of this was that things would (should) continue to work if 1 of the hosts went away. Anyway, at that point, all 3 hosts are able to communicate with each other over the management network, but the engine still thinks that all 3 hosts are down, and is unable to manage anything. Any suggestions on how to proceed would be much appreciated.

I honestly cannot remember what I did (if anything) to the actual hosts when this all started, but my troubleshooting steps today have been to try to fiddle with the vlan settings and /etc/sysconfig/network-scripts/ files on the problematic host to switch from the original vlan (1) to the new vlan (10). > > Until then, I'm troubleshooting why the hosted engine isn't really working, since the other two hosts are operational. > > The hosted engine is "running" -- I can access and navigate around the oVirt Manager. > However, it appears that all of the storage domains are down, and all of the hosts are "NonOperational".

what host os version or ovirt node version I choose for my production setup
by dhanaraj.ramesh＠yahoo.com 13 Apr '21

13 Apr '21

We had done successful POC of ovirt node & HE with 4.4.5 version and now planning for production. However since 4.4.5 ovirt node& HE based on centOS 8.3, yet Red hat announced CentOs8.3 EOL by End of this year, is there any progress/plan to release ovirt nodes with CentOS stream soon? if we choose to go with Centos 8.3 based oVirt node, what could be the consequences in near term especially when it's come to next production release upgrade? Kindly suggest me which Host version I should choose for Production setup?

Adding physical RAM to the hosts
by David White 13 Apr '21

13 Apr '21

As readers will already know, I have three oVirt hosts in a hyperconverged cluster. I had a DIMM with too many errors on it, so I scavenged from a spare server that I had in my office precisely for this purpose. I went ahead and replaced all of the RAM, because the DIMMs in my spare were a different speed. While I was at it, I doubled the RAM on this 1 oVirt host. So now, two hosts have 32GB each. And the 3rd host now has 64GB. So total, I should have 128GB of RAM available to the cluster. The engine recognizes that the host now has 64GB of RAM. Screenshot below: [Screenshot from 2021-04-12 19-59-59.png] However, the engine dashboard still shows that only ~93GB of RAM are available to the cluster (screenshot below). [Screenshot from 2021-04-12 19-58-15.png] Should I be worried that the oVirt dashboard hasn't updated to ~128GB (or a bit less, I guess)? Do I need to do anything else?

Glad that it worked, and thanks for the report! I strongly recommend that you spend some time investigating what/who/why it was changed. This is most likely a mistake someone made at some point. It might be broader than just this file, or it might be some other kind of problem (e.g. a machine crashed in the middle of engine-setup and left files corrupted). If you can't find why/who, and suspect it's a bug, we'd definitely like to get more information. Some things you can check (other than usual site-specific things like who logged in, when you changed stuff there, etc.): - All /var/log/ovirt-engine/setup/* logs, their timestamps, and their contents (e.g. grep them all for "OVESETUP_ENGINE_CORE/enable"). - /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf* - the file itself, and backups (made by engine-setup or otherwise), timestamps etc. - /etc/ovirt-engine/uninstall.d/* - engine-setup (and other related tools) keep there information about all files it created/chagned - mainly used by engine-cleanup Good luck and best regards, -- Didi
