[ovirt-users] 回复：Re: oVirt non-self-hosted HA

[dhy336]

Why not to use hosted-engine for engine HA?  I am wanting to solute engine HA, 
But i do not know how to select haproxy/keepalived  and hosted engine.

Hey Guy's,



If I'm looking to setup the oVirt engine in an HA configuration off the

I want to setup two to four active oVirt engine instances elsewhere and handle 
the HA via something like haproxy / keepalived to keep the entire experience 
seamless to the user.

You will need to set up the oVirt engine service as well as the PG database 
(and ovirt-engine-dwhd service and any other service we run next to the engine) 
as highly available module.In pacemaker[1], for example. You'll need to ensure 
configuration is also sync'ed between nodes, etc.Y.
So already have one ovirt engine setup separately on a vm that manages two 
remote physical hosts.  So familiar with the single host approach which I would 
simply replicate.  At least that’s the idea anyway.  Could you please expand a 
bit on the highly available module and  syncing the config between hosts?

From what I've seen in oVirt, that seems to be possible without the two oVirt 
engines even knowing each other's existence but is it something anyone has ever 
done?  Any recommendations in this case?



Having settings replicated would be a bonus but I would be comfortable if they 
weren't and I handle that myself.

we are running the CI suite with no_root_squash
https://github.com/oVirt/ovirt-system-tests/blob/master/common/deploy-scripts/setup_storage_nfs_el7.sh#L17
while we recommend anonuid=36,anongid=36,all_squash
https://www.ovirt.org/documentation/how-to/troubleshooting/troubleshooting-nfs-storage-issues/
and this explains why it can write as root in the CI env.

Thanks for the report!

Re: [ovirt-users] hosted-engine Debug Help

[RabidCicada]

Indeed that is the problem.  I am sshing as root

The only possible explanations I have for this working in the ovirt
autmated testing setup are:

   - Either the ovirt automated tests must be using a host inventory file
   with become: true?
   - The inventory file ssh credentials happen to be to vdsm user? (And
   become is just not doing anything)
   - Some other janky thing that allows the access


It also happens for the immediately following task `Initialize metadata
volume` and many more following that task.

I will correct and then open a pull request to fix with your input that you
believe it's a problem.

Alright.  By differential comparing to successfull postgres-command
sudo-becomes.  It looks like the salient difference is that `Copy
configuration archive to storage` is missing become:true.  Testing now.

The similar postgres commands have become:true while this one does not.

If it's reproducible, it'd be great if you could:
1. Run libvirt with debug logs

3. File a bug on libvirt.

Re: [ovirt-users] ovirt engine HA

[Alex K]

In case you need HA for the engine you need to deploy it to other hosts
also through the GUI.

In the playbook we have on that task:

but I fear it got somehow ignored.

[ovirt-users] Disable OVS?

[Jayme]

I'm constantly seeing this error in all of my host syslogs:

 ovs-vsctl: ovs|1|db_ctl_base|ERR|unix:/var/run/openvswitch/db.sock:
database connection failed (No such file or directory)

My cluster is set to linux bridge and not using OVS.  How can I stop the
error message or disable ovs?

Re: [ovirt-users] Why is host rebooted after updates, can it be disabled?

[Pavol Brilla]

It was introducted in 4.2 IIRC, in GUI it is checkbox which is by default
on, cause during upgrade of host, not only oVirt packages are updated, but
also systems ones

in ansible role it was propagated :

Re: [ovirt-users] ovirt engine HA

[FERNANDO FREDIANI]

Is it enough to deploy the Self-Hosted engine in just one Host of the
cluster or is it necessary to repeat the process in each of the nodes that
must be able to run it ?

Thanks
Fernando

[ovirt-users] ISO uploading from GUI/REST with user permissions

[Lloyd Kamara]

Dear Sir/Madam,

The ability to upload ISOs through the web interface and boot
VMs from them is a welcome addition in oVirt release 4.2.2.
I am grateful to the people behind the implementation of this.

Consider a scenario in which you wish to allow *end-users*
to upload ISOs to one or more Data Domains.  The users can
then use the uploaded ISOs to boot their VMs.

Is it possible to grant a user permission to upload ISOs through
the web interface?  I tried to to this under oVirt release 4.2.2
by doing the following:

- adding the 'SuperUser' role to a target user for a specific
Data Domain, which enables the user to log onto the Administration Portal.

- adding the 'DiskCreator' role to the same target user for the
same Data Domain, which, I would hope, would allow the user to
both create disks and upload ISOs within that Data Domain.

Disk creation in the Data Domain for the target user works as expected;
ISO upload does not.  A dialog appears with the message: 'Operation
Canceled  Error while executing action: User is not authorized to
perform this action.'

Here is the message that appears in /var/log/ovirt-engine/engine.log
when an attempt at uploading an ISO is made by the target user:


INFO
[org.ovirt.engine.core.bll.storage.disk.image.TransferImageStatusCommand]
(default task-40) [5b3fef06-49c8-4c34-81a3-a20fa691709a] No permission
found for user 'a9fde4c3-97a3-4494-84f8-08041a16710c' or one of the
groups he is member of, when running action 'TransferImageStatus',
Required permissions are: Action type: 'USER' Action group:
'CREATE_DISK' Object type: 'System'  Object ID:
'aaa0----123456789aaa'.


If one assigns the DiskCreator role System permission for the target
user then that user can upload ISOs without problem.  Unfortunately,
the user can upload ISOs - and create disks - in *all* data domains.

To re-iterate, is it possible to grant an end-user permission to
upload ISOs to specific data domains through the web interface without
granting an all-encompassing System permission?


Best wishes,
  Lloyd Kamara

I notice that almost every time I perform an oVirt host upgrade the host is

You will need to set up the oVirt engine service as well as the PG database
(and ovirt-engine-dwhd service and any other service we run next to the
engine) as highly available module.
In pacemaker[1], for example.
You'll need to ensure configuration is also sync'ed between nodes, etc.

Re: [ovirt-users] Issues with ZFS volume creation

Or try to create the vdev on the multipath devices, what does lsblk -s says ? 
It will show you the top level device to be used.

Re: [ovirt-users] oVirt non-self-hosted HA

[Johan Bernhardsson]

Hi,

It's not entirely clear what you want to do.

Ovirt is an interface that will control hardware nodes that runs virtual 
servers. It's similar to vmwares vsphere.


The engine need to be replicated so that if one goes down the other have 
the exact same information.

I want to setup two to four active oVirt engine instances elsewhere and
handle the HA via something like haproxy / keepalived to keep the entire
experience seamless to the user.


From what I've seen in oVirt, that seems to be possible without the two

oVirt engines even knowing each other's existence but is it something
anyone has ever done?  Any recommendations in this case?

Having settings replicated would be a bonus but I would be comfortable
if they weren't and I handle that myself.

Re: [ovirt-users] Issues with ZFS volume creation

[Staniforth, Paul]

Hello Tal,

 ZFS is probably detecting a partition table on the disks, you 
could delete the partition tables on /dev/sda,/dev/sdb  ... etc, or you could 
use the force option of ZFS create making sure they aren't mounted somewhere.

Hello All,
I know this question is might be out of Ovirt scope, but I don't have anywhere 
else to ask for this issue (ZFS users mailing doesn't work), so I am trying my 
luck here anyway
so the issues go as follows :

Installed ZFS on top of CentOs 7.4 with Ovirt 4.2 , on physical Dell R720 with 
15 sas  10 k 1.2TB each attached to PERC H310 adapter, disks are configured to 
non-raid, all went OK, but when I am trying to create new zfs pool using the 
following command:

zpool create -m none -o ashift=12 zvol raidz2 sda sdb sdc sdd sde sdf sdg sdh 
sdi sdj sdk sdl sdm
I get the following error below:
/dev/sda is in use and contains a unknown filesystem.
/dev/sdb is in use and contains a unknown filesystem.
/dev/sdc is in use and contains a unknown filesystem.
/dev/sdd is in use and contains a unknown filesystem.

/dev/sdj is in use and contains a unknown filesystem.

[ovirt-users] ??help??Build a local development environment

[TT-mao]

Hi, guys:
I am currently trying to build an ovirt development environment (including 
engine and vdsm) locally using official documentation, but it will never build 
successfully.
First, I successfully built the rpm package through 
(https://www.ovirt.org/develop/developer-guide/vdsm/developers/)
But the vdsm rpm package that I built can't be applied to the engine 
environment. Add hosts on the ovirt gui interface. The engine backend will 
reinstall vdsm.


How do you create a local development environment?___

Re: [ovirt-users] Persistent dummy interface

[RabidCicada]

I do this on CentOS with /etc/modules-lomodules-loadad.d.
You can stick a file in there that is basically just a bash script that
loads your driver and then does the ip link command all the same time.

[ovirt-users] nfs 4.2 support

[Alan Griffiths]

Hi,

I noticed that when mounting nfs domains in ovirt 4.1 using
auto-negotiate it settles on v4.1.

Is this due to lack of live storage migration as referenced in this bug

https://bugzilla.redhat.com/show_bug.cgi?id=1464787

Are there other known issues with 4.2 support?

Thanks,

Alan

[ovirt-users] Persistent dummy interface

[spfma . tech]

Hi,
 What is the right way to get a persistent dummy interface ? I need an internal 
network for lab purpoposes, so I created a dummy link "ip link add dummy_1 type 
dummy" and I was able to assign my logical network to it. But how to make it 
persistent ? Of course, after a reboot, the dummy device has gone and the 
server becomes non operational because of this non-compliant network. I have to 
recereate it by hand in order to get things work. Regards

Hi Bryan,

You can go into the template -> storage tab -> select the disk and remove
it there

You should already find all the relevant log entries in a file
called 
/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-ansible-create_target_vm-{timestamp}-{hash}.log

Can you please share it?

Re: [ovirt-users] Fw: Data Operations On Any Host

[Fred Rolland]

Jeremy,

There is currently no option to restrict the data operations to specific
hosts.

You can disable this feature in the DB, disable "DataOperationsByHSM" in
the vdc_options table.

Note that since it is enabled by default since 4.1, all testing flows were
done with this option.

Regards,
Fred

Re: [ovirt-users] virtual machine actual size is not right

[Pavol Brilla]

Hi

just small note why size of disk differs between ovirt and system:

30G in ovirt = 30*1024*1024*1024 bytes = 32212254720 bytes = 32.2GB which
you see in parted output


I dont know that much about storage to help with it and I can only cite
from oVirt webpages[1]:
Thin Provision allocates 1 GB at the time the virtual disk is created and
sets a maximum limit on the size to which the disk can grow. The virtual
size of the disk is the maximum limit; the actual size of the disk is the
space that has been allocated so far. Thinly provisioned disks are faster
to create than preallocated disks and allow for storage over-commitment.
Thinly provisioned virtual disks are recommended for desktops.

[ovirt-users] Install oVirt node without Internet repository

[G, Maghesh Kumar (Nokia - IN/Bangalore)]

Hi


Description of problem:

Cannot add host - install fails & Install oVirt node without Internet repository



Version: Ovirt-4.2

Host is installed with RHEL 7.4



Actual results:

Host KVM02 installation failed. Command returned failure code 1 during SSH 
session 'root@192.175.2.231'

I found that right now on my oVirt Nodes in my test environment does not NOT 
connect to the internet...
Basically, i need the offline repository to access from oVirt nodes without 
Internet access.

Please guide us how to proceed

[ovirt-users] Engine reports

[Anantha Raghava]

Hi,

I see that oVirt DWH is installed with Version 4.2.x. Now, how do I take 
the reports? I version 3.5, we had Jasper reports module using which we 
could take utilization reports. Can we do something similar here?

Same thing, the engine in this case is "self-hosted", as in, it runs in a VM 
hosted on the cluster that it is managing.  I am a beginner here, but from my 
understanding, each node is always checking on the health of the engine VM.  If 
the engine is missing (ie, the host running it has gone down), then another 
available, healthy host will spawn up the engine and you will regain access. 
In my experience this has worked very reliably.  I have 2 hosts, both are 
"able" to run the engine VM.  If I take one host down, I am not able to load 
the engine GUI.  But if I wait a few minutes, then I regain access, and see 
that the engine is now running on the remaining healthy host. Vincent

If your node running self-hosted engine crashes, the hosted engine will be 
started up on another node. It just takes a few minutes for this all to happen, 
but it works reliably in my experience.
