[ovirt-users] planned datacenter maintenance 21.12.2018 20:30 UTC

[Evgheni Dereveanchin]

Hi everyone,

The network switch stack used by the oVirt PHX datacenter needs a reboot
which is scheduled for tomorrow. It is expected to be a fast task yet it
may cut all networking including shared storage access for all of our
hypervisors for a couple of minutes.

For this reason I'll shut down non-critical services beforehand and pause
CI to minimize I/O activity and protect against potential VM disk
corruption.

Maintenance window: 21.12.2018  20:30 UTC - 21:30 UTC

Services that may be unreachable for short periods of time during this
outage are:
* Package repositories
* Glance image repository
* Jenkins CI

Other services such as the website, gerrit and mailing lists are not
affected and will be operating as usual.

Hi Yedidyah,

please find the logs at the following URL:
http://www.klaros-testmanagement.com/files/ovirt/ovirt-restore-logs.tar.gz

Let me know once you received them safely so I can remove them again.


Done.



Thanks, removed.



I also added the restore.log containing the actual error which occured
during the restore.

Since this was a clean system I restored on, the setup has been executed
after the database restore, so the setup logs probably contain nothing
of interest. I added them anyway.


Sorry I wasn't clear enough. I meant the setup logs on the machine used
to create the backup. So that I can try to see why your backup contained
this function. Do you still have these by any chance?

Indeed, I can't see anything wrong in the logs above.


Sorry for misunderstanding, this totally makes sense.

I added the setup logs i found at:
http://www.klaros-testmanagement.com/files/ovirt/ovirt-setup-logs.tar.gz

Again, please let me know once I can remove them.


Done.


Thanks, removed.





Please let me know if there is anything I can add to this.


If you do not have setup logs from the original machine, at least try
to think about its history and tell us notable points - including entire
version history, setup/upgrade (or similar) problems you had there (and
perhaps worked around), etc.



We started with one of the first 4.0 releases and updated the system on
a regular basis since then. We almost never skipped a release.


The last log there is ovirt-engine-setup-20171231170651-lb3q89.log ,
meaning it was last upgraded almost a year ago. Were there indeed no
more upgrades since?



20171231170651 is most probably the date when we installed the last
major release (4.2.0). We did a lot more updates since and I now have a
suspicion what went wrong here.

We naively assumed that a yum update is sufficient for a minor upgrade
of the engine installation.


:-(


Rereading the documentation I think we were
missing explicit engine-setup calls after each minor upgrade.


Indeed



It may be the case, that the extra call to engine-setup is required to
not be part of the yum update.


engine-setup might need to ask the user questions, so we do not run it
inside yum update.

As long as it clear to users that this is required this is totally ok 
for me.



I think in this case it would be a good
idea to warn users that this step has not yet been taken and the update
is not completed yet.


Do you think you would have noticed? It's not that hard to add such a
message during yum update, but not sure it's that helpful.


Yes, I would probably have noticed that. Sooner or later ... :)


Perhaps we can also make the engine check e.g. if the setup package is
newer than itself, and warn the user in the admin ui.

I think that both is a good idea. Some applications even go the way to 
lock out users from the GUI until a necessary database migration has 
been executed by an administrator. Your mileage may vary here but this 
is the solution I would favor.




Could this be the cause for the missing logs and behavior discrepancies?

If yes, would another call to engine-setup in the current state fix this
and allow us to produce correct backups in the future?


If you still have the source machine, then yes, it should be enough.
Run engine-setup, then engine-backup again to backup, then restore
on the new machine.


Thanks, will do.




The log indicates the machine was upgraded to ovirt-engine-4.2.0.2 ,
which didn't remove the uuid functions. The bug I linked at before,
1515635, was fixed in 4.2.1.

Based on this, I think the best solution for now would be the patch
you suggested. Would you like to open a bug for this and push a patch
to gerrit? I can do this as well if you prefer. Bug summary line
should probably be something like:

engine-setup fails after restoring a backup taken with 4.2.0


I currently fear that would only cure the symptom.


Another solution would be to try using the same engine version during
restore (4.2.0.2), and only upgrade later. This is a bit hard, because
we do not have separate repos for each version, although they do
include all released versions - so you can try e.g.:

yum install ovirt-engine-4.2.0.2-1.el7

(meaning, after you remove existing 4.2.7, or you can try yum downgrade).

I didn't try this myself, not sure how well it would work. There might
be older dependencies to handle, and/or it might break due to too-new
stuff.


I don't think this is necessary.


Obviously, the best solution is to upgrade more often and backup more
often, and have a smaller difference between backup version and restore
version, ideally no difference. But I realize this does not always

[Jacob Green]

What if you cannot run the VM, so its not running on any specific host. 
But you want the XML to identify the  information.



Thank you.

are you mounting via the gluster GUI? I'm not sure how it handles 
mounting of manual gluster volumes, but the direct-io-mode=enable mount 
option comes to mind. I assume direct-io is also enabled on the other 
volume? It needs to be on all of them.

[ovirt-users] Re: Disk full

[suporte]

We moved the VM disk to the second gluster. On the ovirt-engine I cannot see 
the old disk, only the disk attached to the VM on the second gluster. 
We keep having the errors concerning the disk full. 
Using CLI I can see the image on the first gluster volume. So ovirt-engine was 
able to move the disk to the second volume but did not delete it from the first 
volume.

[ovirt-users] Active Storage Domains as Problematic

[Stefan Wolf]

Hello,

 

I ,ve setup a test lab with 3 nodes installed with centos 7

I configured manualy gluster fs. Glusterfs is up and running

After that I deployed a selfhosted engine

And add the two other hosts, at the beginning it looks good, but without
changing anything I got following error by two hosts

Before glusterfs I had a setup with nfs on 4. Server

 

Where is the problem?

[ovirt-users] Upload via GUI to VMSTORE possible but not ISO Domain

[Ralf Schenk]

Hello,

I can successfully upload disks to my Data-Domain ("VMSTORE") which is
NFS. I also can upload .iso Files there. (No porblems with SSL or
imageio-proxy). Why is the ISO Domain not available for Upload via GUI ?
Does a separate ISO Domain still make sense ? The ISO Domain is up and
running. And ist it possible to filter out the hosted_storage where the
engine lives for uploads ?

Do you see the image on the gluster volume mount? Can you provide the gluster 
volume options and version of gluster?

Hi, 

I have a all in one intallation with 2 glusters volumes. 
The disk of one VM filled up the brick, which is a partition. That partition 
has 0% free disk space. 
I moved the disk of that VM to the other gluster volume, the VM is working with 
the disk on the other gluster volume. 
When I move the disk, it didn't delete it from the brick, the engine keeps 
complaining that there is no more disk space on that volume. 
What can I do? 
Is there a way to prevent this in the future? 

Many thanks 

José
