 Hi,

 I recently had to shutdown my oVirt system which contains both the
 engine and the host. After it came back up, the host was not able to
 initialize anymore from the oVirt UI.

 First it kept getting stuck in a loop with setting "ExecutingStarted:
 Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode."

 This was being repeated over and over again. It also gave this error:
 Host pc331 does not comply with the cluster Default networks, the
 following networks are missing on host: 'ovirtmgmt'

 Even though I am using that interface (ovirtmgmt) to access the system
 and 'ip addr show' shows that it's set up properly.

 I tried some more things, including upgrading the host, When I do
 that, the status changes to 'Installing' and later to 'Install
 Failed'.

 Here are the engine.log, vdsm.log and ovirt-host-deploy*.log:

 Any idea what is going wrong (what I'm doing wrong) and how to solve it?
 Thanks in advance!

[ovirt-users] Re: uploading ISOs

[William Dossett]

Not convinced   chrome is easy enough, done it many times... I used to use 
firefox but there's a few web apps I use that it does not play well with...

One annoying thing about chrome is that if you clear your history and cookies, 
it blows away your certs as well.  Not sure if FF does that or not.

But thanks again, all up and running now!

[ovirt-users] Possible to use Console via Mac web browser?

[Jayme]

I recall in the past (on a bit older of an oVirt build) I was able to
launch VM consoles from my web browser.  I believe it may have been using
spice html5 at the time, is this still possible?  Currently launching
console downloads the typical .vv file.

What is currently the best/easiest method to access VM consoles using
MacOS?

[ovirt-users] Re: Unable to revive host after a reboot

[Douglas Landgraf]

Hi,

- Might be useful the output from the command (host):
  - tree /var/lib/vdsm

I noticed in host-deploy/engine.log the following error: "Cannot find
a valid baseurl for repo: base/7/x86_64"
Are you able to test and see if the host is able to reach the baseurl
from the repo?

[William Dossett]

Ok, why didn't I do that before ☹

Connection to ovirt-imageio-proxy service has failed. Make sure the service is 
installed, configured, and ovirt-engine certificate is registered as a valid CA 
in the browser.

Installed the cert and looks like it is ok now, thanks!

[ovirt-users] Re: uploading ISOs

[William Dossett]

My destination domain is a vmstore on Gluster.  Its HCI environment.  The 
upload does not complete, it says Paused by System, resuming it, 15 seconds 
later goes back to Paused by System

 



 

I’m kind of at a loss how to proceed with my testing if I can’t get my ISOs 
uploaded….  I’m on 4.2.4.

 

Is it correct that this does not need to be an ISO domain?  It does not have to 
be NFS?

 

Thanks, appreciate any guidance.

 

Bill

Please keep in mind that there is currently a bug open where destination data 
domain is on block storage:

https://bugzilla.redhat.com/show_bug.cgi?id=1588400

 

The upload succeeds, but actually has failed and you are not able then to 
attach this iso to vm.

As I already wrote inside the bugzilla, in my opinion the scenario where one 
has block storage domains is the most important one for this feature so 
that he/she can completely avoid nfs if not needed for main storage

Hopefully fix will be in 4.2.6. I don't know how much actively worked on right 
now...

No, this is "normal". Should not affect ballooning.

And the line where the GuestMonitor is starting? You need to get back
to the time the VM was started or restart MOM (mom-vdsm service).

Yes I think so.

[William Dossett]

Thank you,  That was what I was using…. But I was told that an ISO domain is no 
longer necessary, is that correct?  I can upload to VMStore?  Or any Domain?

 

When I try to upload a Windows Server 2016 ISO, it starts to upload, then goes 
to Paused by System, if I resume, it goes back to Paused by system after about 
15 secs.

 

It is uploading to VMStore which has 498GB free of total 499 GB.

 

Thanks

Bill

Hi William,

 

You can now upload image (and ISO) using image-io.

You can find more information about it here -

VDO provides dedupe/compression at the block layer. More at
https://github.com/dm-vdo/kvdo

It provides space savings, but there's a performance drop depending on the
workloads you run. It's better to turn on VDO if you're using SSD devices
as the performance decrease is less noticeable. But please run your own
benchmark tests to decide.
The vdo kernel module has been available since CentOS 7.5

You can't use same device where already non vdo volume provisioned.You need
fresh device for vdo.

[Jayme]

Is it possible to apply vdo on an existing HCI build or does it need to be
rebuilt?

[ovirt-users] Re: Error trying out the new VDO dedupe/compression settings in cockpit

[Jayme]

I burned the node image yesterday 4.2.5.1 July 31.  I've been playing with
Ovirt install for the past week and burned node iso a few times and this
image is the first time I've ever seen vdo options in gdeploy.

How do I make sure I have the most recent version of gdeploy, is node
behind?

Also can anyone chime in about vdo, is it recommended for use now?  What is
its main benefit, does it offer performance boost or more for saving disk
space?

[ovirt-users] Re: MoM - Not working ? How to use it ?

[Martin Sivak]

Hi,

sorry I could not answer yesterday.

What you need to check is whether the VM is reported as ready in the
log (/var/log/vdsm/mom.log). You should see lines like:

2018-08-01 10:52:25,648 - mom.GuestMonitor.Thread - INFO -
GuestMonitor-ms-vhost-1 starting
2018-08-01 10:52:25,648 - mom.GuestManager - DEBUG - added monitor for
guest c4f1ea89-457a-4049-97d7-11cf751d00f0
2018-08-01 10:52:25,648 - mom.Monitor - DEBUG - Using optional fields:
set(['swap_out', 'swap_usage', 'balloon_cur', 'swap_total',
'balloon_min', 'major_fault', 'swap_in', 'io_tune_current',
'mem_unused', 'balloon_max', 'minor_fault', 'io_tune',
'mem_available'])
2018-08-01 10:52:25,649 - mom.Monitor - DEBUG - Using fields:
set(['vcpu_count', 'vcpu_period', 'vcpu_user_limit', 'vcpu_quota'])

...

2018-08-01 10:52:25,808 - mom.Monitor - INFO - ms-vhost-1 is ready

There might be a message reporting that some required data fields are
not available and the ballooning won't work for that VM in such case.

Best regards

Martin Sivak

Is there a possibility of recovering data from gluster? When you say lost -
are the files deleted from all bricks?

Are these qemu snapshot or gluster volume snapshot?

Well, it *could*, you know - it's a bit hard to guess without any logs...
But I do not think so.

Was the upgrade from 4.2.4, or something older?

If it was disabled directly by engine-setup, it should definitely be
mentioned in the log. Otherwise, it's hard to say. Seems like 'systemctl
disable someservice' does not log this anywhere. You might get a clue by
checking the exact time you started getting error from your hosts (nfs
clients) and try to correlate that with engine-side logs.

Assuming you do not want to run hosted-engine, if I were you, I'd run the
engine on a KVM vm on that host (using virt-manager/virsh/whatever) and
the NFS server on another VM.

Hello,
unfortunately this is not that straight. You would need to take care about
deployment into all hosts that would use use this filter. For the engine
part you would need to add your filter name into the database.

Hopefully this helps.

Best regards,
Ales

[ovirt-users] [No question] NFS disabled, hosts wandering tearful

[Nicolas Ecarnot]

Hello,

This is a simple testimony about what happened yesterday in one of our DC.
This DC runs on a dedicated bare-metal engine, oversized compared to the 
need, thus I've added a NFS service on it to host a small storage domain 
and the ISO storage domain.
Yesterday, after having received the colorful announce about the 4.2.5 
version, I decided to upgrade.
As our engine was still on a CentOS 7.4, I first upgraded its OS version 
to 7.5, then reboot. Smooth.

Then I followed the very usual oVirt engine upgrade path. Smooth.
Eventually, I upgraded the hosts with ovirt-ansible-cluster-upgrade as 
usual.


The result was frightening because the hosts were put in maintenance, 
upgraded, back to life, seen unavailable, unreachable, connecting, 
alive, rebooted, then back to another turn and looping...
During this, the SPM role was obviously jumping around, and that did not 
help the debug.


In the end, it appeared that something during an upgrade stopped and 
disabled the NFS service. My hosts partially relied on it, so after 
having restarted the NFS service, all came back to life.


The NFS disabling may come from the CentOS upgrade, except if someone 
tells me it could come from something on the oVirt side?


I'm sure the RH people will advice me not to run NFS on the engine, but 
apart this event, I had no trouble doing this in years.
