Hi,
please try downgrading ansible-core, the new ansible-core uses python 3.9 for 
which the modules are missing. In my installation downgrading ansible-core 
solves the problem, until this is resolved upstream.
Cheers,

Sorry, correction, the new ansible core uses python 3.11, which is the 
problematic one, 3.9 is ok with the old ansible-core.

[ovirt-users] Re: Issue upgrading 4.4 to 4.5 Gluster HCG

[Alessandro De Salvo]

Hi,

the error with XML and gluster is the same I reported with a possible 
fix in vdsm in another thread.


The following fix worked for me, i.e. replacing the following line in 
/usr/lib/python3.6/site-packages/vdsm/gluster/cli.y


429c429
< if (el.find('stripeCount')): value['stripeCount'] = 
el.find('stripeCount').text

---
> value['stripeCount'] = el.find('stripeCount').text

In this way, after restarting vdsmd and supervdsmd, I was able to 
connect to gluster 10 volumes. I can file a bug if someone could please 
point me where to file it :-)


Cheers,


    Alessandro

Hey All,

I am having an issue upgrading from 4.4 to 4.5.
My setup
3 Node Gluster (Cluster 1) + 3 Node Cluster (Cluster 2)

If i recall the process correctly, the process I did last week:

On all my Nodes:
dnf install -y centos-release-ovirt45 --enablerepo=extras

On Ovirt Engine:
dnf install -y centos-release-ovirt45
dnf update -y --nobest
engine-setup

Once the engine was upgraded successfully I ran the upgrade from
the GUI on the Cluster 2 Nodes one by one although when they came
back, they complained of "Host failed to attach one of the Storage
Domains attached to it." which is the "hosted_storage", "data"
(gluster).

I thought maybe its due to the fact that 4.5 brings an update to
the glusterfs version, so I decided to upgrade Node 3 in my
Gluster Cluster and it booted to emergency mode after the install
"succeeded".

I feel like I did something wrong, aside from my bravery of
upgrading so much before realizing somethings not right.

My VDSM Logs from one of the nodes that fails to connect to
storage (FYI I have 2 Networks, one for Mgmt and 1 for storage
that are up):

[ovirt-users] Re: failed to mount hosted engine gluster storage - how to debug?

[Alessandro De Salvo]

Hi,

please try this workaround, replace the following line in 
/usr/lib/python3.6/site-packages/vdsm/gluster/cli.py



value['stripeCount'] = el.find('stripeCount').text


with:

if (el.find('stripeCount')): value['stripeCount'] = 
el.find('stripeCount').text



Then restart vdsmd and supervdmsd and retry. It worked for me, and it 
looks like a serious bug for people upgrading to glusterfs 10.


Cheers,


    Alessandro

[ovirt-users] Re: Installing new self-hosted engine v4.5.0 on gluster 10

[Alessandro De Salvo]

Hi,

I think I've found the root of the problem, it is a bug in vdsm. Gluster 
10 produces xml description without the stripeCount tag, while vdsm 
expects it to be present.


I've tried to fix it simply adding a check in 
/usr/lib/python3.6/site-packages/vdsm/gluster/cli.py


429c429
< if (el.find('stripeCount')): value['stripeCount'] = 
el.find('stripeCount').text

---
> value['stripeCount'] = el.find('stripeCount').text

In this way, after restarting vdsmd and supervdsmd, I'm able to connect 
to gluster 10 volumes.


I guess this should be fixed in possibly a more proper way upstream.

Cheers,


    Alessandro

[ovirt-users] Re: failed to mount hosted engine gluster storage - how to debug?

[Alessandro De Salvo]

Hi,
I think it may be a problem with vdsm and gluster 10, I’ve reported a similar 
issue in another thread. Vdsm is throwing an exception when parsing the XML 
from the gluster volume info when using the latest gluster version 10. This is 
particularly bad when the gluster server updates have been completed by moving 
the op-version, as it’s basically irreversible and it’s not even possible to 
easily downgrade gluster. If you downgrade to or use a gluster 8 works in fact.
I’m digging the code of vdsm to see if I can find the root cause.
Cheers,

   Alessandro

[ovirt-users] Re: Error 500 on Hosted Engine admin portal!!!

[Alessandro De Salvo]

Hi,
I’m not sure if it works with the web installer, but if you deploy with CLI you 
can use the following to ask the installer to pause before running engine-setup:

hosted-engine --deploy --ansible-extra-vars=he_pause_before_engine_setup=true

This gives you the time to ssh and exclude the offending package before the 
installer attempts to upgrade any package.
Cheers,

   Alessandro

[ovirt-users] Re: Best Openstack version to integrate with oVirt 4.2.7

[Alessandro De Salvo]

Hi,

we're also extensively using ceph via cinder on docker (Kolla project), 
but we're stuck on Pike for the missing keystone v3 support.


While cinderlib is desirable and it's a good solution for simple uses, 
adding support for keystone v3 and keeping the native cinder interface 
would also be good, for cases where you already have an openstack 
infrastructure available and you want to manage a storage system from a 
single place. The other reason to keep the current solution, at least 
for now, is what Matthias is mentioning: the transition phases.


How difficult it is to add the keystone v3 support for the storage side 
in ovirt, given you should already have the needed libs as you use them 
for the networking?


Thanks,


   Alessandro

Hi,

we are extensively using Ceph storage using the present 
OpenStack/Cinder integration in oVirt 4.2 which works for us. 
Openstack version in use is Pike.


I already heard about the plan to move to cinderlib which sounds 
promising. I very much hope there will be a migration scenario for 
users of "full" Openstack/Cinder installations when upgrading to oVirt 
4.3.

Nobody working on oVirt is testing any release of Openstack in the 
recent years.


The Cinder/Ceph support was released as tech preview in 3.6, and no 
work was

done since then, and I think this will be deprecated soon.

For 4.3 we are working on a different direction, using Cinderlib
https://github.com/Akrog/cinderlib

This is a way to use Cinder drivers without Openstack installation.
The same library is used to provide Cinder based storage in Kubernetes.
https://github.com/Akrog/ember-csi

You can find an early draft here for this feature. Note that it is 
expected to be

updated in the next weeks, but it can give you some idea on what we are
working on.
https://github.com/oVirt/ovirt-site/blob/f88f38ebb9afff656ab68a2d60c2b3ae88c21860/source/develop/release-management/features/storage/cinderlib-integration.html.md 



This will be tested with some version of Cinder drivers. I guess we 
will have

more info about it during 4.3 development.

    At the moment I have two separate lab environments:
    oVirt with 4.2.7
    Openstack with Rocky (single host with packstack allinone)

    just trying first integration steps with these versions, it seems
    I'm not able to communicate with glance, because I get in engine.log
    2018-11-10 17:32:58,386+01 ERROR
[org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy]

    (OpenStack response error code: 404)


I think Glance support should work. Elad, which version of Glance was
tested for 4.2?

Regarding which Openstack version can work best with oVirt, maybe
Openstack guys I added can give a better answer.

Nir

    Nothing in glance logs on openstack, apparently.
    In my test I'm using
    http://xxx.xxx.xxx.xxx:9292 as provider url
    checked the authentication check box and
    glance user with its password
    35357 as the port and services as the tenant

    a telnet on port 9292 of openstack server from engine to 
openstack is ok


    similar with cinder I get:
    2018-11-10 17:45:42,226+01 ERROR
[org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy]
    (default task-50) [32a31aa7-fe3f-460c-a8b9-cc9b277deab7] Not Found
    (OpenStack response error code: 404)

    So before digging more I would lile to be certain which one is
    currently the best combination, possibly keeping as fixed the oVirt
    version to 4.2.7.

    Thanks,

[ovirt-users] Re: Upgrade from 4.1.9 to 4.2.3 fails to upgrade postgresql

[Alessandro De Salvo]

Hi Ian,
I had the very same problem, but the upgrade was complaining for a
different locale.
Try to add the following line at the beginning of the
file /opt/rh/rh-postgresql95/root/usr/bin/postgresql-setup, after the
initial comments and before the code:


export PGSETUP_INITDB_OPTIONS="--lc-collate=en_GB.UTF-8"

Once done, please try again to run engine-setup, thus the upgrade.
You might need to add more options to PGSETUP_INITDB_OPTIONS, in case
the upgrade procedure still complains.
Cheers,

Alessandro

Re: [ovirt-users] Hosted Engine VM not imported

[Alessandro De Salvo]

Ciao Simone,

many thanks. So, how are we supposed to use those hooks? Should we just 
create a file 
/usr/share/ovirt-hosted-engine-setup/ansible/hooks/enginevm_before_engine_setup/enginevm_before_engine_setup.yml 
with the instructions to restore? Do you have an example for doing that?


For the moment I think I'll stick to the old procedure by calling 
--noansible, as you suggest.


I think the documenttation should be updated anyways, at least to add 
the --he-remove-storage-vm and --he-remove-hosts options, as well as the 
new procedure and the override with --noansible. Also, wouldn't it be 
safer to stick to the old procedure until the new one is fully 
operational? Or maybe at least a warning to the user, otherwise no one 
will ever be able to restorage a db and have it all functional with the 
default options.


Thanks,


    Alessandro

Hi,

I have just migrated my dev cluster to the latest master,
reinstalling the engine VM and reimporting from a previous backup.
I'm trying with 4.3.0-0.0.master.20180222192611.git01e6ace.el7.centos

I had a few problems:

- the documentation seems to be outdated, and I just find by
searching the archives that it's needed to add the two
(undocumented) options --he-remove-storage-vm --he-remove-hosts

- despite the fact I selected "No" to running the engine-setup
command in the VM (the ovirt appliance), the engine-setup is
executed when running hosted-engine --deploy, and as a result the
procedure does not stop allowing to reload the db backup. The only
way I found was to put the hosted-engine in global maintenance
mode, stop the ovirt-engine, do an engine-cleanup and reload the
db, then it's possible to add the first host in the GUI, but must
be done manually

- after it's all done, I can see the hosted_storage is imported,
but the HostedEngine is not imported, and in the Events I see
messages like this:

VDSM atlas-svc-18 command GetVolumeInfoVDS failed: Image path does
not exist or cannot be accessed/created:

(u'/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/c815ec3f-6e31-4b08-81be-e515e803edce',)

   the path here is clearly wrong, it should be

/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/b7bc6468-438c-47e7-b7a4-7ed06b786da0/c815ec3f-6e31-4b08-81be-e515e803edce,
and I see the hosted_engine.conf in the shared storage has it
correctly set as vm_disk_id=b7bc6468-438c-47e7-b7a4-7ed06b786da0.


Any hint on what is not allowing the HostedEngine to be imported?
I didn't find a way to add other hosted engine nodes if the HE VM
is not imported in the cluster, like we were used in the past with
the CLI using hosted-engine --deploy on multiple hosts.


Ciao Alessandro,
with 4.2.1 we introduced a new deployment flow for hosted-engine based 
on ansible.
In this new flow we run a local VM with a running engine and we use 
that engine to create a storage domain and a VM there.
At the end we shutdown the locally running engine and we move it's 
disk over the disk of the VM created by the engine on the shared 
storage. At this point we don't need anymore the autoimport process 
since the engine migrated there already contains the engine VM and its 
storage domain.


We have an RFE, for this new flow, to add a mechanism to inject an 
existing engine backup to be automatically restored before executing 
engine-setup for migration/disaster-recovery scenarios.
Unfortunately it's still not ready but we have an hook mechanism to 
have hosted-engine-setup executing custom ansible tasks before running 
engine setup; we have an example 
in /usr/share/ovirt-hosted-engine-setup/ansible/hooks/enginevm_before_engine_setup/enginevm_before_engine_setup.yml.example


Otherwise the old flow is still there, you have just to add 
--noansible and everything should work as in the past.



Thanks for any help,


    Alessandro

Hi,

I have just migrated my dev cluster to the latest master, reinstalling 
the engine VM and reimporting from a previous backup. I'm trying with 
4.3.0-0.0.master.20180222192611.git01e6ace.el7.centos


I had a few problems:

- the documentation seems to be outdated, and I just find by searching 
the archives that it's needed to add the two (undocumented) options 
--he-remove-storage-vm --he-remove-hosts


- despite the fact I selected "No" to running the engine-setup command 
in the VM (the ovirt appliance), the engine-setup is executed when 
running hosted-engine --deploy, and as a result the procedure does not 
stop allowing to reload the db backup. The only way I found was to put 
the hosted-engine in global maintenance mode, stop the ovirt-engine, 
do an engine-cleanup and reload the db, then it's possible to add the 
first host in the GUI, but must be done manually


- after it's all done, I can see the hosted_storage is imported, but 
the HostedEngine is not imported, and in the Events I see messages 
like this:


VDSM atlas-svc-18 command GetVolumeInfoVDS failed: Image path does not

and I see the hosted_engine.conf in the shared storage has it 
correctly set as vm_disk_id=b7bc6468-438c-47e7-b7a4-7ed06b786da0.



Any hint on what is not allowing the HostedEngine to be imported? I 
didn't find a way to add other hosted engine nodes if the HE VM is not 
imported in the cluster, like we were used in the past with the CLI 
using hosted-engine --deploy on multiple hosts.

Re: [ovirt-users] Enabling libgfapi disk access with oVirt 4.2

[Alessandro De Salvo]

Hi again,

OK, tried to stop all the vms, except the engine, set engine-config -s 
LibgfApiSupported=true (for 4.2 only) and restarted the engine.


When I tried restarting the VMs they are still not using gfapi, so it 
does not seem to help.


Cheers,


Alessandro

I’ll try restarting the engine. Is it really needed to stop all the 
VMs and restart them all? Of course this is a test setup and I can do 
it, but for production clusters in the future it may be a problem.

Hi ,

    The procedure to enable gfapi is below.

1) stop all the vms running
2) Enable gfapi via UI or using engine-config command
3) Restart ovirt-engine service
4) start the vms.

Hope you have not missed any !!

The compatibility flag is correctly showing gfapi should be

The data center and cluster have the 4.2 compatibility flags as well.

However, when starting a VM with a disk on gluster I can still

Any clue of what I'm still missing?

Re: [ovirt-users] Ovirt & Ceph

[Alessandro De Salvo]

Hi Rajat,
3 is the bare minimum, but yes, it works well, as I said before. But you still 
have to decide weather you want to have more resiliency for ovirt, and standard 
NFS is not helping much.
If you plan to run your cinder or openstack all in one box as VM in ovirt as 
well you should consider moving from standard NFS to something else, like 
gluster.
Cheers,

  Alessandro

Re: [ovirt-users] Ovirt & Ceph

[Alessandro De Salvo]

Hi Rajat,
OK, I see. Well, so just consider that ceph will not work at best in your 
setup, unless you add at least a physical machine. Same is true for ovirt if 
you are only using native NFS, as you loose a real HA.
Having said this, of course you choose what's best for your site or affordable, 
but your setup looks quite fragile to me. Happy to help more if you need.
Regards,

   Alessandro

Re: [ovirt-users] Ovirt & Ceph

[Alessandro De Salvo]

Hi,
oh, so you have only 2 physical servers? I've understood they were 3! Well, in 
this case ceph would not work very well, too few resources and redundancy. You 
could try a replica 2, but it's not safe. Having a replica 3 could be forced, 
but you would end up with a server with 2 replicas, which is dangerous/useless.
Okay, so you use nfs as storage domain, but in your setup the HA is not 
guaranteed: if a physical machine goes down and it's the one where the storage 
domain resides you are lost. Why not using gluster instead of nfs for the ovirt 
disks? You can still reserve a small gluster space for the non-ceph machines 
(for example a cinder VM) and ceph for the rest. Where do you have your cinder 
running?

Alessandro

One if the ceph clusters we use had exactly this setup: 3 DELL R630 (ceph 
jewel), 6 1TB NL-SAS disks so 3 mons, 6 osds. We bound the cluster network to a 
dedicated interface, 1Gbps. I can say it works pretty well, the performance 
reaches up to 100MB/s per rbd device, which is the expected maximum for the 
network connection. Resiliency is also pretty good, we can loose 2 osds (I.e. a 
full machine) without impacting on the performance.

Re: [ovirt-users] Ovirt & Ceph

[Alessandro De Salvo]

Hi Rajat,
sorry but I do not really have a clear picture of your actual setup, can you 
please explain a bit more?
In particular:

1) what to you mean by using 4TB for ovirt? In which machines and how do you 
make it available to ovirt?

2) how do you plan to use ceph with ovirt?

I guess we can give more help if you clarify those points.
Thanks,

Re: [ovirt-users] Ovirt & Ceph

[Alessandro De Salvo]

Hi,
having a 3-node ceph cluster is the bare minimum you can have to make it 
working, unless you want to have just a replica-2 mode, which is not safe.
It's not true that ceph is not easy to configure, you might use very easily 
ceph-deploy, have puppet configuring it or even run it in containers. Using 
docker is in fact the easiest solution, it really requires 10 minutes to make a 
cluster up. I've tried it both with jewel (official containers) and kraken 
(custom containers), and it works pretty well.
The real problem is not creating and configuring a ceph cluster, but using it 
from ovirt, as it requires cinder, i.e. a minimal setup of openstack. We have 
it and it's working pretty well, but it requires some work. For your reference 
we have cinder running on an ovirt VM using gluster.

Yes, I just found a trick to re-import the disk, using qemu-img to dump
the image on a file from rbd:/, create a new disk in ovirt
and use qemu-img to copy it back on the new image. Technically it is
working, but it's a bit convoluted. Any plans to add the relevant
support in ovirt?

Are you talking to the upload button in the Disks tab? I do not see how
I can upload to cinder/ceph from there. The only way I found was the
trick described above.

[ovirt-users] Exporting VMs using cinder disks and importing ceph disks from cinder

[Alessandro De Salvo]

Hi,
I'm trying to export VMs using ceph disks on ovirt 4. The export itself
works, but the disks are not saved in the export domains, only the VM
definition is stored. Also, I cannot easily re-import them, unless I
clone the VM instead of importing it, it just fails.
Cinder itself can backup volumes, if instructed to do so.
However, let's say I would like to export the machine from an ovirt
infrastructure and load it into another one passing by the export domain
and sharing the same underlying ceph cluster. I could easily load the VM
from the export domain into the second ovirt infrastructure, but how can
I define the disk, whose volume exists in the cinder instance, in the
second ovirt? I do not see any obvious way to map an existing cinder
volume into ovirt, without creating a new disk, which would not be
helpful.
As a consequence of all this, in case of problems with the disks, there
is no way to recover them.
Any help?
Thanks,

Alessandro

[ovirt-users] Error while extending a cinder/ceph disk

After this, the cinder image is flagged as illegal and I can just delete
it.
Extending the image on the cinder side is possible, and the command
"cinder extend " works, but then the new size is not properly
reported back in ovirt.
Any clue?

Re: [ovirt-users] oVirt and Ceph

[Alessandro De Salvo]

Hi Nir,
yes indeed, we use the high-availability setup from oVirt for the 
Glance/Cinder VM, hosted on a high-available gluster storage. For the DB 
we use an SSD-backed Percona Cluster. The VM itself connects to the DB 
cluster via haproxy, so we should have the full high-availability.
The problem with the VM is the first time when you start the oVirt 
cluster, since you cannot start any VM using ceph volumes before you 
start the Glance/Cinder VM. It's easy to be solved, though, and even if 
you autostart all the machines they will automatically start in the 
correct order.

Cheers,

Alessandro

We are using a VM managed by ovirt itself for keystone/glance/cinder with

So far we are happily using ceph in this way. The only drawback of this

attached, but the running machines survives without problems even if the
cinder VM is down.

Thanks for the info Alessandro!

This seems like the best way to run cinder/ceph, using other storage for
these vms, so cinder vm does not depend on the vm managing the
storage it runs on.

If you use highly available vms, ovirt will make sure they are up all the time,
and will migrated them to other hosts when needed.

just to answer myself, I found these instructions that solved my problem:

It's all working now.

libvirtError: XML error: invalid auth secret uuid



In fact the uuid of the secret used by ovirt to hotplug seems to be 
the ceph secret (masked here as ), while libvirt 
expects the uuid of the libvirt secret, by looking at the instructions 
http://docs.ceph.com/docs/jewel/rbd/libvirt/.

Anyone got it working?
Thanks,

[ovirt-users] Using ceph volumes with ovirt

[Alessandro De Salvo]

Hi,
I'm happily using our research cluster in Italy via gluster, and now I'm 
trying to hotplug a ceph disk on a VM of my cluster, without success.
The ceph cluster is managed via openstack cinder and I can create 
correctly the disk via ovirt (3.6.6.2-1 on CentOS 7.2).
The problem comes when trying to hotplug, or start a machine with the 
given disk attached.
In the vdsm log of the host where the VM is running or starting I see 
the following error:



jsonrpc.Executor/5::INFO::2016-05-30
