HCL: 4.3.7: Hosted engine fails
by Christian Reiss
Hey all,
Using a homogeneous ovirt-node-ng-4.3.7-0.20191121.0 freshly created
cluster using node installer I am unable to deploy the hosted engine.
Everything else worked.
In vdsm.log is a line, just after attempting to start the engine:
libvirtError: the CPU is incompatible with host CPU: Host CPU does not
provide required features: virt-ssbd
I am using AMD EPYC 7282 16-Core Processors.
I have attached
- vdsm.log (during and failing the start)
- messages (for bootup / libvirt messages)
- dmesg (grub / boot config)
- deploy.log (browser output during deployment)
- virt-capabilites (virsh -r capabilities)
I can't think -or don't know- off any other log files of interest here,
but I am more than happy to oblige.
notectl check tells me

The odd thing is the hosted engine vm does get started during initial
configuration and works. Just when the ansible stuff is done an its
moved over to ha storage the CPU quirks start.
So far I learned that ssbd is a mitigation protection but the flag is
not in my cpu. Well, ssbd is virt-ssbd is not.
I am *starting* with ovirt. I would really, really welcome it if
recommendations would include clues on how to make it happen.
I do rtfm, but I was unable to find anything (or any solution) anywhere.
Not after 80 hours of working on this.
Thank you all.

OVirt Engine Server Died - Steps for Rebuilding the Ovirt Engine System
by bob.franzke＠mdaemon.com
Full disclosure here.....I am not an Ovirt Expert. I am a network Engineer that has been forced to take over sysadmin duties for a departed co-worker. I have little experience with Ovirt so apologies up front for anything I say that comes across as stupid or "RTM" questions. Normally I would do just that but I am in a bind and am trying to figure this out quickly. We have an OVirt installation setup that consists of 4 nodes and a server that hosts the ovirt-engine all running CentOS 7. The server that hosts the engine has a pair of failing hard drives and I need to replace the hardware ASAP. Need to outline the steps needed to build a new server to serve as and replace the ovirt engine server. I have backed up the entire /etc directory and the backups being done nightly by the engine itself. I also backed up the iscsi info and took a printout of all the disk arrangement . The disk has gotten so bad at this point that the DB won't back up any longer. Get fatal:backup failed error when
trying to run the ovirt backup tool. Also the Ovirt management site is not rendering and I am not sure why.
Is there anything else I need to make sure I backup in order to migrate the engine from one server to another? Also, until I can get the engine running again, is there any tool available to manage the VMs on the hosts themselves. The VMs on the hosts are running but need a way to manage them if needed in case something happens while the engine is being repaired. Any info on this as well as what to backup and the steps to move the engine from one server to another would be much much appreciated. Sorry I know this a real RTM type post but I am in a bind and need a solution rather quickly. Thanks in advance.

Question about HCI gluster_inventory.yml
by John Call
Hi ovirt-users,
I'm trying to automate my HCI deployment, but can't figure out how to
specify multiple network interfaces in gluster_inventory.yml. My servers
have two NICs, one for ovirtmgmt (and everything else), and the other is
just for Gluster. How should I populate the inventory/vars file? Is this
correct?
[root@rhhi1 hc-ansible-deployment]# pwd
/etc/ansible/roles/gluster.ansible/playbooks/hc-ansible-deployment
[root@rhhi1 hc-ansible-deployment]# cat gluster_inventory.yml

Re: null
by Strahil
I do use automatic migration policy.
The main question you have to solve is:
1. Why the nodes became 'Non-operational' .Usually this happens when the management interface (in your case HoatedEngine VM) could not reach the nodes over the management network.
By default, management is going over the ovirtmgmt network. I guess you have created the new network. Marked that new network as management network and then the switch was off , causing 'Non-Operational state'.
2. Migrating VMs is usually a safe approach, but this behavior is quite strange. If a node ia Non-operational -> there could be no successful migration.
3. Some of the VMs got paused due to storage issue. Are you using GlusterFS, NFS or iSCSI ? If yes, you need to clarify why you lost your storage.
I guess for now you can mark each VM to be migrated only manually (VM -> Edit) and if they are critical VMs , set a high Availability from each VM's Edit options.
In such case, if a node fails, the VMs will be restarted on another node.
4. Have you setup node fencing ? For example APC, iLo, iDRAC and other fencing mechanisms can allow the HostedEngine use another Host as fencing proxy and to reset the problematic Hypervisor.
P.S.: You can define the following alias in '~/.bashrc' :
alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'
Then you can verify your VMs even when a HostedEngine is down:
'virsh list --all'

ovirt 4.3.7 + Gluster in hyperconverged (production design)
by adrianquintero＠gmail.com
Hi,
After playing a bit with oVirt and Gluster in our pre-production environment for the last year, we have decided to move forward with a our production design using ovirt 4.3.7 + Gluster in a hyperconverged setup.
For this we are looking get answers to a few questions that will help out with our design and eventually lead to our production deployment phase:
Current HW specs (total servers = 18):
1.- Server type: DL380 GEN 9
2.- Memory: 256GB
3.-Disk QTY per hypervisor:
- 2x600GB SAS (RAID 0) for the OS
- 9x1.2TB SSD (RAID[0, 6..]..? ) for GLUSTER.
4.-Network:
- Bond1: 2x10Gbps
- Bond2: 2x10Gbps (for migration and gluster)
Our plan is to build 2x9 node clusters, however the following questions come up:
1.-Should we build 2 separate environments each with its own engine? or should we do 1 engine that will manage both clusters?
2.-What would be the best gluster volume layout for #1 above with regards to RAID configuration:
- JBOD or RAID6 or…?.
- what is the benefit or downside of using JBOD vs RAID 6 for this particular scenario?
3.-Would you recommend Ansible-based deployment (if supported)? If yes where would I find the documentation for it? or should we just deploy using the UI?.
- I have reviewed the following and in Chapter 5 it only mentions Web UI https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infr...
- Also looked at https://github.com/gluster/gluster-ansible/tree/master/playbooks/hc-ansib... but could not get it to work properly.
4.-what is the recommended max server qty in a hyperconverged setup with gluster, 12, 15, 18...?
Thanks,
Adrian

Re: Issue deploying self hosted engine on new install
by Sang Un Ahn
Hi,
I have figured it out that the root cause of the deployment failure is timing out while the hosted engine was trying to connect to host vis SSH as shown in engine.log (located in /var/log/ovirt-hosted-engine-setup/engine-logs-2019-12-31T06:34:38Z/ovirt-engine):

Connecting to host via SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details.]
The FQDN of hosted engine (alice-ovirt-engine.sdfarm.kr <http://alice-ovirt-engine.sdfarm.kr/>) is resolved as well as the host (alice-ovirt-01.sdfarm.kr <http://alice-ovirt-01.sdfarm.kr/>) and SSH is the one of services that are allowed by firewalld. I believe the rules of firewalld is automatically configured during the deployment to work with hosted engine and the host. Also root access is configured to be allowed at the first stage of deployment.
I was just wondering how I can verify the hosted engine can access to the host at this stage? Once it fails to deploy, the deployment script make all things rolled back (I believe it cleans all up) and the vm-status of hosted-engine is un-deployed.
Thank you in advance,
Best regards,

Re: 4.2.8 to 4.3.7 > Management slow
by Strahil
You can manually change the I/O scheduler of the disks and if that works better for you, put a rule in udev.
Here is mine:
[root@engine rules.d]# cat /etc/udev/rules.d/90-default-io-scheduler.rules
ACTION=="add|change", KERNEL=="sd*[!0-9]", ATTR{queue/scheduler}="none"
ACTION=="add|change", KERNEL=="vd*[!0-9]", ATTR{queue/scheduler}="none"
[root@engine rules.d]# cat /sys/block/vda/queue/scheduler

Re: Issue deploying self hosted engine on new install
by thomas＠hoberg.net
Yes, I have had the same and posted about it here somewhere: I believe it's an incompatible Ansible change.
Here is the critical part if the message below:
"The 'ovirt_host_facts' module has been renamed to 'ovirt_host_info', and the renamed one no longer returns ansible_facts"
and that change was made in the transition of Ansible 2.8* to 2.9, from what I gathered.
I guess I should just make it a bug report if you find the same message in your logs.

Re: Node not starting | blk_cloned_rq_check_limits: over max size limit
by Strahil
You can check https://access.redhat.com/solutions/2437991 & https://access.redhat.com/solutions/3014361
You have 2 options:
1. Set a udev rule like this one (replace NETAPP with your storage)
ACTION!="add|change", GOTO="rule_end" ENV{ID_VENDOR}=="NETAPP*", RUN+="/bin/sh -c 'echo 4096 > /sys%p/queue/max_sectors_kb'" LABEL="rule_end"
2. Set max_sectors_kb in devices section of multipath.conf
You will need to stop LVM and then flush the device map , so the new option to take effect (faster is to reboot)
Good Luck & Happy New Year.
