[ovirt-users] Re: Engine insists on running on 1 host in cluster when that host is online

2021-10-12 Thread David White via Users 
I think I'm making progress.

I had 1 storage domain that was hardly used, so in the oVirt UI, I migrated 
production data onto a different storage domain, and then I put that storage 
domain into maintenance mode. I was then able to edit the mount options for 
that storage domain.

The path is still as it was originally:
cha1-storage.my-domain.com:/data

But I added the following as a mount option. Does this look right?
backup-volfile-servers=cha2-storage.my-domain.com

Essentially, my goal here is for high availability storage. I want to be able 
to reboot cha1-storage, and still have everything remain online.

For the Hosted Storage, can I do this from the command line without putting 
that into maintenance mode? This is what I see right now:

[root@cha2-storage dwhite]# hosted-engine --get-shared-config storage 
--type=he_local
storage : cha1-storage.my-domain.com:/engine, type : he_local

> Check the scores of the systems via 'hosted-engine --vm-status'.
That must be the problem.

Host a has a score of 1800.
Host c has a score of 3400.

I was able to deploy the hosted-engine to Host B through the web UI.

1) Put it in maintenance mode

2) Installation -> Reinstall ... and make sure to select "Deploy" for the 
hosted-engine

How do I fix / change the score on the first node?

Separately, I'm still confused how I would update oVirt to use the 2nd replica 
as a mount point. Healing the volume seems to me like a completely different 
task than reconfiguring oVirt to mount the 2nd replica in its mount options?

And if the engine is running on the other host a, then I turn host c back on, 
the engine shuts down from a, and comes back up on c.
Check the scores of the systems via 'hosted-engine --vm-status'.Check vdsm logs

I originally built the cluster as a single-node hyperconverged. I then added

   - Currently, the Engine is deployed on two of the servers (a and c). But any

on that server c. I cannot migrate the engine off of c.
And if the engine is running on the other host a, then I turn host c back on, 
the engine shuts down from a, and comes back up on c.
   
   - How do I "fix" this so that the engine will run on host a, even when host 
c is turned on?   

   - How do I deploy the hosted-engine to host b?   

   
   - Is it as simple as logging into host b, and running "hosted-engine 
--deploy" ?

The web console can show a note icon if an entity has a comment.

In this blog we’ll explore how to monitor the oVirt environment so you can
visualize performance, resources and trends.

In this blog:

   - How to use oVirt dashboards.
   - Explanation of default dashboards.
   - How to create custom dashboards from the built-in options that come
   with oVirt.

The "comment" field was designed exactly for this purpose.

[ovirt-users] How to add a note to a VM

2021-10-12 Thread Gianluca Cecchi 
Hello,
I know there are the "Comment" and "Description" columns available in many
areas of the Webadmin Gui.
But there are some tasks, like "shutdown VM" or "Management -> Maintenance"
for a host, where I can specify a "reason" for doing that task and then a
note icon appears, aside the object, with the mouse over showing the note
text, like in this image:
https://drive.google.com/file/d/1v3Yd2t7AtuRFMT6HPFYYZqYUmJLMHYMY/view?usp=sharing

Is there a way to do it in general? So for example I have a VM and I want
to put a note (for some colleague, or to remind me to do an action
tomorrow, ecc...)

And btw: how can I manually remove the note? Eg I shutdown a VM and fill in
the "Reason" field and then in a second moment I want to remove it

Thanks in advance,

Which version?

If you are on ovirt 4.4, please share output of:

Looks like the host is configured correctly - the http backend is
using the right CA file
to access the host.

The CA file on engine side (/etc/pki/ovirt-engine/ca.pem) does not
match the CA file on the host
(/etc/pki/vdsm/certs/cacert.pem).

Which files did you change when we added the thirdparty CA approved SSL?

[ovirt-users] Engine insists on running on 1 host in cluster when that host is online

2021-10-12 Thread David White via Users 
About a month ago, I completely rebuilt my oVirt cluster, as I needed to move 
all my hardware from 1 data center to another with minimal downtime.
All my hardware is in the new data center (yay for HIPAA compliance and 24/7 
access, unlike the old place!)

I originally built the cluster as a single-node hyperconverged. I then added 
nodes to it, and then, finally, I reconfigured gluster to run in a replica 2 / 
arbiter 1 configuration.

As of now:

-   I have 4 compute hosts
-   Gluster is running fine and replicating fine between the two full replicas, 
along with the arbiter node

-   I need to revisit my recent email about gluster replication speed, though

However, I'm worried about two things:

-   I think that my hosts, and hosted-engine, are all still configured to use 
the single mount point from the original single-node hyperconverged ... i.e. if 
I shutdown / reboot that host, then the storage "goes away"

-   How do I reconfigure oVirt to use the 2nd replica as a secondary mount 
point?



-   Currently, the Engine is deployed on two of the servers (a and c). But any 
time one of those servers is online (c), the hosted-engine insists on running 
on that server c. I cannot migrate the engine off of c.


And if the engine is running on the other host a, then I turn host c back 
on, the engine shuts down from a, and comes back up on c.

-   How do I "fix" this so that the engine will run on host a, even when host c 
is turned on?
-   How do I deploy the hosted-engine to host b?

-   Is it as simple as logging into host b, and running "hosted-engine 
--deploy" ?

looks like certificate is not trusted (invalid/missing root certificates on 
given machine?)

did you try "Test connection" button on the upload page? If it fails, you need 
to download the certificate from [1] and make it trusted in your browser
