[ovirt-users] Re: Failed to activate Storage Domain --- ovirt 4.2

[fabian . rapetti]

Hi all.
I'm using Ovrit 4.3.10 two nodes cluster and facing the same error (second 
metadata area corruption). 
Does anybody know if there is a solution for that?

Our software include:  
lvm2-2.02.186-7.el7_8.2.x86_64
Virt Node 4.3.10
kernel  3.10.0-1127.8.2.el7.x86_64
device-mapper-multipath-libs-0.4.9-131.el7.x86_64
libvirt-4.5.0-33.el7_8.1.x86_64

Thanks in advance

[ovirt-users] Re: about the password of the engine host and worker KVM hosts

[Kiran Rajendra]

Hi Tommy,

Yes, We can change the password of root user in both Oracle Linux 
Virtualization Manager (OLVM) and KVM hosts.
All the communicates between KVM host to Oracle Linux Virtualization Manager 
(OLVM) happens using public/private ssl keys. 

Thank you

If your Host is stale and is having thr SPM role -> some tasks will fail.

Also, the VMs on such host won't be recovered unless VM HA is enabled (with 
storage lease).

 

For prod, I would setup that.

Keep in mind that the fencing is issued by another host in the cluster, so you 
need minimum 2 hosts in a cluster before starting setup & test.

Everybody, hi:

I would like to ask, after the configuration of power management on the host, 
under what circumstances will work? 

That is, when does the engine send a request to the IPMI module to restart the 
power supply?

 

Is it necessary to configure power management modules in the production 
environment? 

Are there any risks?

 

Thanks!

though those credentials.

 

You should be able to change the root password without issue.

Thanks to Ales' workaround node is up and active in the engine.
There is some work to be done on CentOS Stream 9 side but looks like we can
start soon working on the engine side for supporting the CentOS Stream 9
nodes properly.

[ovirt-users] Slow mirrors, installation fails

[Andrea Chierici]

Dear all,
I am trying to install a new ovirt deployment with self hosted engine.
I've been trying since yesterday but it always fails.
On the deployment host I get this error:

[ ERROR ] Hosted Engine deployment failed: please check the logs for 
the issue, fix accordingly or re-deploy from scratch.
  Log file is located at 
/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20210917144651-ecm06v.log


I connected to the console of the hosted engine and in dnf.log I found this:

Indeed the speed of the mirrors seems quite low and even on another 
ovirt deployment I have, the metadata download speed is around 40kb, 
while for all other centos repos it is at least 10MB.

Am I missing something?

Thanks,
Andrea

Thanks Chen!

A few updates on my side:
attaching host to engine failed in 2 different places:
- wrong repositories for oVirt Node optional packages (solved now via
https://gerrit.ovirt.org/c/ovirt-release/+/116760 )
- failing to setup network, reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=2005213
- vdsm is built with /usr/bin/python as interpreter, not sure why, still
digging into it. Workaround: `ln -s /usr/bin/python3 /usr/bin/python` but
this may be due to the custom vdsm build.

 You can give it a run with a 4.4.8 standalone engine in its own
 DC/Cluster as a start.
 Or you can deploy a new engine as in the 4.4.8 flow but using
 https://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm for
 providing the repositories
 Please note also these cases have never been tested yet.

*Test scenarios:*

   - 1. ISO check - *PASS*
   - 2. GUI Install oVirt-node 4.5 - *Failed* (Met bug *Bug 2002640*
    - No way to have
   CentOS Stream 9 booting on installed system with /home on md device )
   - Workaround:
  - lvchange -a y /dev/mapper/onn-home
  - and eventually activating also remaining maps (grep mapper
  /etc/fstab to see them)
  - exit from the rescue shell
  - 3. Install oVirt-node 4.5 on HP UEFI machine - *Failed* (Probably
   due to the kernel not signed, see attachment "UEFI-Failed")
   - 4. Cockpit UI Sanity Test - *Pass*
   - 5. Upgrade Testing - *Not Cover* (known limitations)
   - 6. Engine & Hosted Engine - *Not Cover* (known limitations)

 Nice!
 If SHE not available, what would be the procedure to install the
 standalone engine before deploying the host?
 Or could I try to deploy the node using a 4.4.8 standalone engine in
 its own DC/Cluster?

[ovirt-users] about the password of the engine host and worker KVM hosts

[Tommy Sway]

I have successfully installed and deployed OLVM, where the Engine uses a
separate physical server and the virtual machines work on other worker
servers.

Due to the company's internal security policy, I now need to change the root
user password for all servers. Is that ok?

Will cluster running be affected?

 

Thanks!
