[ovirt-users] Engine and nodes ssh setup

[spfma . tech]

Hi,
   I am still trying to make my restored hosted engine communicate with the 
nodes without success.   There is a step I am not sure : is root user on the 
engine supposed to be able to log into nodes without password or not ? In my 
case it doesn't   By the way, where are located the certificates actually used 
for these communications ?   Regards

Re: [ovirt-users] How to generate Swagger specification of the oVirt API?

Hi Juan,

I saw the discussion in users-list:
http://lists.ovirt.org/pipermail/users/2017-April/081618.html
and I'm curious about how to generate the Swagger specfication of existing
oVirt API (or maybe can generate by ovirt-engine-api-model?).
Could you give me some advices on the generating tools or maybe some points
to change during the procedure of building ovirt-engine?

Michael



The JSON file that I mentioned in that mail was generated using I tool 
that I started to write, but that I never finished. I just have uploaded 
the patch that adds it to the ovirt-engine-api-metamodel project:


  [WIP] Generate Swagger specification
  https://gerrit.ovirt.org/89337

Note that it is by no means complete, it is just an experiment. Take a 
look if you are curious.


Truth is that I don't plan to work on that. Would be nice if you can 
take it and complete it. If you complete it, then it could be integrated 
in the build process of the ovirt-engine-api-model project, so that it 
is generated automatically.

Re: [ovirt-users] VDSM SSL validity

I do not think it ever was exposed to engine-config - I think it's a
bug in that page.

You should be able to update it with psql, if needed - something like this:

select fn_db_update_config_value('VdsCertificateValidityInYears','2','general');

I didn't try this myself.

To get an sql prompt, you can use engine-psql, which should be
available in 4.2.2,
or simply copy the script from the patch page:

https://gerrit.ovirt.org/#/q/I4d9737ea72df0d7e654776a1085901284a523b7f

Also, some people claim that the use of certificates for communication between
the engine and the hosts is an internal implementation detail, which should not
be relevant to PCI DSS requirements. See e.g.:

https://ovirt.org/develop/release-management/features/infra/pkireduce/

 Hi,

 I setup an hyperconverged solution with 3 nodes, hosted engine on
 glusterfs.
 We run this setup in a PCI-DSS environment. According to PCI-DSS
 requirements, we are required to reduce the validity of any certificate
 under 39 months.

 I saw in this link
 https://www.ovirt.org/develop/release-management/features/infra/pki/ that i
 can use the option VdsCertificateValidityInYears at engine-config.

 I'm running ovirt engine 4.2.1 and i checked when i was on 4.2 how to
 edit the option with engine-config --all and engine-config --list but the
 option is not listed

 Am i missing something ?

 I thing i can regenerate a VDSM certificate with openssl and the CA conf
 in /etc/pki/ovirt-engine on the hosted-engine but i would rather modifiy 
 the
 option for future host that I will add.

In oVirt, we support replica 3 or replica 3 with arbiter (where one of the
3 bricks is a low storage arbiter brick). To expand storage, you would need
to add in multiples of 3 bricks. However if you only want to expand compute
capacity in your HC environment, you can add a 4th node.

Re: [ovirt-users] HostedEngine with HA

[Hanson Turner]

Hi Carlos,

If you're using shared storage across the nodes/hypervisors, the 
HostedEngine VM should already be HA.


Sometimes this allows the engine to drop while restarting it on another 
node. Usually when this happens the rest of the nodes running VMs stay 
up, and things resync when the downed node comes back.


IE the only one to lose pings is the Hosted-Engine. Unless ofcourse 
there were VM's on the same node, in which case, if they were HA VMs 
they will be restarted/resumed depending on your settings.



Thanks,

Hanson

After a few minutes your vm will be shutdown by the High

Not sure what exactly you mean:

1. You want to copy the engine to another machine and remove from the first?

Use engine-backup

2. It's a hosted-engine and you want to migrate the engine vm to another host?

You can use the gui and migrate it like any other vm

3. Something else?

Please see the link I sent before for migrating to hosted-engine.

Another option is to simply install the engine on one of the machines.

I didn't try this myself, but people reported that it works.

This will be simpler than hosted-engine, but will not provide the HA
that hosted-engine does.
If you want to do this, you should do something like:

on the existing engine machine:
1. engine-backup --mode=backup --file=b1 --log=l1
2. Stop and disable the engine and dwh on this machine
3. Copy b1 to the host you want to install it on

On the host you want the engine on:
4. Install ovirt-release package (same as you installed on the engine machine)
5. Install the package ovirt-engine
6. engine-backup --mode=restore --file=f1 --log=r1 --provision-db
--provision-dwh-db
7. engine-setup
8. Make sure the name of the old engine now resolves to the IP address
of the new host,
by updating your DNS (e.g. add a CNAME record) or /etc/hosts

For more details check engine backup/restore documentation.

Yes, it does look like that.

Can you share details of
# gluster peer status
from your 3 nodes

And also the address of the first host in the oVirt engine and below from
the HE engine:

# su - postgres -c "psql -d engine -c \"select * from gluster_server; \""

[ovirt-users] FCP storage domain wiped, recovery process

[aduckers]

I’ve got an environment with:
13 servers in the oVirt default cluster
Hosted Engine 4.1.3.5-1.el7.centos
Storage provided by FC san

One of the FC LUNs, being used as a Data Domain, was wiped/reformatted through 
a confluence of events.

How can I clean this up and re-add this LUN back?  I can’t Detach it, as there 
are VMs/Templates attached to it.  When I try to remove the Templates, it tells 
me it can’t since the storage domain is inactive.

What’s the best way to clean up from this?

Thanks

Re: [ovirt-users] Ovirt vm's paused due to storage error

[Darrell Budic]

I’ve also encounter something similar on my setup, ovirt 3.1.9 with a gluster 
3.12.3 storage cluster. All the storage domains in question are setup as 
gluster volumes & sharded, and I’ve enabled libgfapi support in the engine. 
It’s happened primarily to VMs that haven’t been restarted to switch to gfapi 
yet (still have fuse mounts for these), but one or two VMs that have been 
switched to gfapi mounts as well.

I started updating the storage cluster to gluster 3.12.6 yesterday and got more 
annoying/bad behavior as well. Many VMs that were “high disk use” VMs 
experienced hangs, but not as storage related pauses. Instead, they hang and 
their watchdogs eventually reported CPU hangs. All did eventually resume normal 
operation, but it was annoying, to be sure. The Ovirt Engine also lost contact 
with all of my VMs (unknown status, ? in GUI), even though it still had contact 
with the hosts. My gluster cluster reported no errors, volume status was 
normal, and all peers and bricks were connected. Didn’t see anything in the 
gluster logs that indicated problems, but there were reports of failed heals 
that eventually went away. 

Seems like something in vdsm and/or libgfapi isn’t handling the gfapi mounts 
well during healing and the related locks, but I can’t tell what it is. I’ve 
got two more servers in the cluster to upgrade to 3.12.6 yet, and I’ll keep an 
eye on more logs while I’m doing it, will report on it after I get more info.

monitor the VM like you would any other host.


We use omd/check_mk.

Right now there isn't an oVirt specific monitor plugin for check_mk.

I know what I said is probably pretty obvious, but just in case.

ok, got it !
just add clone parameter for add function.


vm = vms_service.add(
types.Vm(
name=vm_name,
cluster=types.Cluster(

),
stateless=False,

Hi,

I want to create a cloned virtual machine based on a template with SDK API 
python and i don't find the parameter to indicate the clone action for the disk

Re: [ovirt-users] FCP storage domain wiped, recovery process

[aduckers]

I have not tried to destroy it yet - I didn’t want to try that without 
understanding how that would affect all the other objects that are related 
(vms, templates, etc..).
If destroying it will also clean those up, or allow me to delete them, then 
that sounds like it might be the way to go.

Hi,

Did you try to put it into maintenance then destroy it?

Re: [ovirt-users] Adding host to hosted-engine /w gluster cluster. (On ovirt Node 4.2.1.1)

I was referring to oVirt's engine.log. Found under
/var/log/ovirt-engine/engine.log

I actually do want to go replica 5. Most VM's it runs are small(1 Core,1gb

Ok, in this case - in addition to adding the new nodes to cluster, you will
also need to add bricks to the volume and increase the replica count to 5.
You can do this using the "Add Bricks" from the Bricks tab on selection of
a gluster volume. Ensure that you set the replica count to 5 here. This
should be done once you successfully add the new hosts to the cluster.

This is because the nodes have not been added (or peer probed) to existing
gluster cluster.
I will need the logs I requested to understand why.

Thanks for sharing!
Why didn't you just upload the qcow2 disk via the UI/API though?
There's quite a bit of manual work that I hope is not needed?

Re: [ovirt-users] ovirt do not start postgresql

[Yedidyah Bar David]

Hi all,

It's very hard to debug this without getting a full picture of the state
of the machine, including logs, versions, flow, etc. Some comments inside.

The fact that your database name is 'engine_20180321150206' most likely means
you have/had some problem, see also:

https://bugzilla.redhat.com/show_bug.cgi?id=1259782

Please check if you have other databases on your machine, why this one was
created, etc.

Some information to understand this can be found in the setup logs.

Re: [ovirt-users] Revised Query for moving Ovirt Engine...

[Nasrum Minallah Manzoor]

Hi Every one,

To make it more clear I am revising my below query!

I have installed 2 nodes  in a cluster and ovirt engine is installed on 
separate machine on Vmware workstation. Now I want to move ovirt engine to one 
of my any nodes. What process  should I go through. Need solution from experts!

Re: [ovirt-users] Can't Add Host To New Hosted Engine - "Server is already part of another cluster"

[Adam Chesterton]

Hi Sahina and Yedidyah,

Thanks for the information and offers of help. I am pleased to report that
I've resolved the issue I had, thanks to the prompting your requests gave
me, and everything is functional. I shall attempt to explain what happened
and how I fixed it.

When I looked at the Gluster peer status, the Host01 was rejected by Host02
and Host03 (I did check this back at the start, but didn't check it again
and things had changed). I followed the Gluster docs to fix the rejected
peer (
http://gluster-documentations.readthedocs.io/en/latest/Administrator%20Guide/Resolving%20Peer%20Rejected/
).

This then gave me a different error message when trying to add Host02 or
Host03, "no available server in the cluster to probe the new server", which
only further confirmed that it was a Gluster issue, as was suggested.

After some hair-pulling and wondering, I finally discovered that, in
Compute > Hosts > Host01 under the General tab, it was complaining that
Gluster was not active (even though it was running). I clicked the action
item link to resolve that, and oVirt appeared to start actually managing
the Gluster service. I could then add my other hosts, import the existing
storage domains, and everything appears good now.

Thanks again for the assistance and prompting me towards the right places
to help me resolve it.

Regards,
Adam

Thank you Yedidyah,

Let me clearify it more that i have 2 ovirt nodes in a cluster. Ovirt engine is 
on seperate machine on vmware workstation. Now i want to move this ovirt engine 
to one of my nodes (which are in a cluster). I need help with the above so that 
i could complete my task.

Thanks in advance!

Not sure what exactly you mean:

1. You want to copy the engine to another machine and remove from the first?

Use engine-backup

2. It's a hosted-engine and you want to migrate the engine vm to another host?

You can use the gui and migrate it like any other vm

3. Something else?
