[ovirt-users] Re: Remove obsolete Gluster hyperconverged doc

[Leo David]

HCI architectured virtualisation enviroments provide quite a lot of
benefits for different implementation scenarios. From rought point of view,
they combine 3 main components in horizontal scaling out fashion ( compute,
storage, networking)
As a starting point, i think you may want to have a look on this:

Ceph native usage (no iscis's or any other abstraction) will do the job and
elavate entire thing to a NEXT level.

Hi,
I think that as long as you can manage to have the pbs client installed on
your nodes, you can setup some functional cli based backup strategy.

[ovirt-users] Re: Upgrade hyperconverged self-hosted ovirt from 4.3 to 4.4

[Leo David]

Hi,
I am interested about these steps too, for a clean an straighforward
procedure.
Althought this plan looks pretty good, i am still wondering:

Step 4
Backup all gluster config files
- could you please let me know what would be the exact location(s) of the
files to be backed up ?

Step 6
Install glusterfs, restore the configs from step 4
- would the configs work with this version ?
- would in theory gluster get back to a previous balanced state ?

Step 9

Deploy the new HE on a new Gluster Volume, using the backup/restore
procedure for HE.
- this assumes to firstly create a new volume based on some aditional new
disks or lvms, right ?

Sorry if maybe I'm missing somethings due to my lack of knowledge.
Cheers,

Leo

[ovirt-users] Re: Hyperconverged setup questions

[Leo David]

Hi,
As a first setup, you can go with a 3 nodes HCI and having the data volume
in a replica 3 setup.
Afterwards, if you want to expand HCI ( compute and storage too) you can
add sets of 3  nodes, and the data volume will automatically become
replicated-distributed. Safely, you can add sets of 3 nodes up to 12 nodes
per HCI.
You can also add "compute only nodes" and not extending storage too. This
can be done by adding nodes one by one.
As an example, I have an implementation where are 3 hyperconverged nodes,
they form a replica 3 volume, and later i have added the 4th node to the
cluster which only adds ram and cpu, whilts consuming storage from the
existing 3 nodes based volume.
Hope this helps.
Cheers,

Leo

[ovirt-users] Re: Delete snapshots task hung

[Leo David]

Thank you for help Strahil,

But although there where 4 images with a status 4 in the database, and did
the update query on them, same bloody message, and vms wont start.
Eventually, ive decided to delete the vms, and do a from scratch
installation. Persistance openshift vms are still ok, so i should be able
to reuse the volumes somehow.
This is why sometimes a subscription is good, when a lack of knowledge on
my side is happening. Production systems should not rely on upstreams
unless there is a strong understanding of the product.
Again, thank you so much for trying helping me out !
Cheers,

Leo

Hi Everyone,
Im still not being able to start the vms... Could anyone give me an advice
on sorign this out ?
Still having th "Bad volume specification" error,  although the disk is
present on the storage.
This issue would force me to reinstall a 10 nodes Openshift cluster from
scratch,  which would not be so funny..
Thanks,

Leo.

[ovirt-users] Re: Delete snapshots task hung

[Leo David]

Hi Everyone,
Please let me know if any thoughts or recommandations that could help me
solve this issue..
The real bad luck in this outage is that these 5 vms are part on an
Openshift deployment,  and now we are not able to start it up...
Before trying to sort this at ocp platform level by replacing the failed
nodes with new vms, I would rather prefer to do it at the oVirt level and
have the vms starting since the disks are still present on gluster.
Thank you so much !


Leo

Thank you Strahil,
But the vm's are not starting at all...
Error is clear: " Exit message: Bad volume specification" ,  but i just do
not understand how to deal with this.

[ovirt-users] Re: VDI

[Leo David]

Thank you very much for the informations.
I'm am sorry for my lack of knowledge,  but the vGPU / vm graphical
performance part is a bit confusing for me at the moment.
As far as i've understood,  if some real decent graphical performance is
needed for the vms,  the only proper way is to install a grid supported gpu
card on the hypervisor,  and have the "slices" assigned to the vms.
A rough look show that this will add at least 4k - 5k dollars per node...
Just as a reference,  its only about "office type" vdi's that only do web
browsing and sometimes youtube videos / skype calls.
Any thoughts for a more less expensive way to achieve this ?

Again, thank you very much !

Thank you Alex,
If you could share the repos for server and client patches would be very
helpful. ( also some install guidance info would it be very good )
I could try them on the actual 4.2.8 that i'm trying to enable vdi's on.
Cheers,

[Leo David]

Thank you for sharing the informations Alex, they are very helpfull. I am
now able to get sound from the vms,  although performance is pretty poor
even with "adjust for performance" setting in Win10. Cannot even talk
about youtube video playing - freezing and crackling.
Could you please be so kind to share the following infos:
1. Have you upgraded the "spice-server" installed on the hosts with a
 newer version than 1.4.0 ? If so,  could you provide me how could I get
these packages ?
2. What graphic card have you used for getting better graphic performance
with the vms ? Im trying to understand what "accepted" card could I use
with my 1U chassis servers...
3. Is it only needed to install the card and the platform will alocate
physical video memory to "desktop" vms ? (  Will the card RAM
be automatically shared across the desktop tyoe vms running on top  of the
host ? )
4. Is it necesarilly to activate sr-iov in the hosts bios or any other
platform configurations ?

I am really sorry for asking too many things,  but im just trying to get
these vdi vms working at least decent...
Thank you so much !

We deploy the changes via gpo directly to the registry, so they take effect

To achieve that all you need to do is create a template of the desktop base
vm, make sure the vm type is set to desktop. Afterwards just create new vms
from that template. As long as the VM type is set to desktop each new VM
will use a qcow overlay on top of the base image.

Taking this a step further you can then create VM pools from said template,
allowing users to dynamically be assigned a new VM on login. Granted pools
are usually stateless, so you need to have network file storage. We use
pools for windows 10 VDI instances, where we use sysprep to autojoin the
new pool vm to the domain where redirected folders are already setup.

For VDI only use spice protocol. By default we found spice to be semi
lackluster, so we do apply custom settings and we have recompiled spice on
both servers and clients with h264 support. This is not 100% necessary, but
makes things like youtube much more usable. We have also backported some
audio patches to KVM. CentOS 8 should resolve a lot of these customizations
that we've had to do.


As far as updating, pretty much. We create a VM from the template, update
it, then push it back as a new version of the template. The pools are set
to always use the latest template version. Users have to log out, then back
in to the VDI system in order to get the new image as logging out will
destroy the users current instance and create a new one on log in.

[ovirt-users] NFS based - incremental backups

[Leo David]

Hello Everyone,
Ive been struggling since a while to find out a propper solution to have a
full backup scenario for a production environment.
In the past, we have used Proxmox, and the scheduled incremenral nfs based
full vm backups is a thing that we really miss.
As far as i know, at this point the only way to have a backup in oVirt /
rhev is by using gluster geo-replication feature.
This is nice, but as far as i know it lacks some important features:
- ability to have incremental backups to restore vms from
- ability to backup vms placed on different storage domains ( only one
storage domain can be geo-replicated !!! some vms have disks on ssd volume,
some on hdd, some on both)
- need to setup an external 3 nodes gluster cluster ( although a workaround
would be to have single bricks based volumes for a single instance )
I know we can create snaps, but they will die with the platform in a fail
scenario, and neither they can be scheduled.
We have found bacchus project that looked promising, although it had a
pretty hassled way to achieve backups ( create snap, create vm from the
snap, export vm to export domain, delete vm, delete snap - all in a
scheduled fashion )
As a mention, Proxmox is incrementaly creating a tar archive of the vm disk
content, and places it to an external network storage like nfs. This
allowed us to backup/reatore both linux and windows vms very easily.
Now, I know this have been discussed before, but i would like to know if
there are at least any future plans to implement this feature in the next
releases.
Personally, i consider this a major, and quite decent feature to have with
the platform, without the need to pay for 3rd party solutions that may or
may not achieve the goal while adding extra pieces to the stack.
Geo-replication is a good and nice feature, but in my oppinion it is not
what a "backup domain" would be.
Have a nice day,

Leo

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Hello everyone,
I am comming back to this issue because of the need to spinup a couple of
Win10 vdi vms, and I can see that the problem still persist - at least for
me.
I am using now a fresh installed and updated oVirt 4.2.8 and latest
guest-tools iso. Still havig very laggy desktop experience on Win10.
Win2012 seems fine, Win7 fine as well.
Is there anyone of you guys having Win10 working at least decent for a vdi
usage ? Any thoughts on this ?
Thank you very much !

Leo

Hi, i think you can generate and use a new uuid, althought i am not sure
about the procedure right now..

[ovirt-users] Re: Replace bad Host from a 9 Node hyperconverged setup 4.3.3

[Leo David]

You will need to remove the storage role from that server first ( not being
part of gluster cluster ).
I cannot test this right now on production,  but maybe putting host
although its already died under "mantainance" while checking to ignore
guster warning will let you remove it.
Maybe I am wrong about the procedure,  can anybody input an advice helping
with this situation ?
Cheers,

Leo

[ovirt-users] Re: Replace bad Host from a 9 Node hyperconverged setup 4.3.3

[Leo David]

Hi Adrian,
I think the steps are:
- reinstall the host
- join it to virtualisation cluster
And if was member of gluster cluster as well:
- go to host - storage devices
- create the bricks on the devices - as they are on the other hosts
- go to storage - volumes
- replace each failed brick with the corresponding new one.
Hope it helps.
Cheers,
Leo

Hi,
Looks like the only way arround would be to create a brand-new volume as
replicated on other disks, and start moving the vms all around the place
between volumes ?

Thank you Strahil,
The engine and ssd-samsung are distributed...
So these are the ones that I need to have replicated accross new nodes.
I am not very sure about the procedure to accomplish this.

The other two hosts will be 192.168.80.192/193  - this is gluster dedicated
network over 10GB sfp+ switch.
- host 2 wil have identical harware configuration with host 1 ( each disk
is actually a raid0 array )
- host 3 has:
   -  1 ssd for OS
   -  1 ssd - for adding to engine volume in a full replica 3
   -  2 ssd's in a raid 1 array to be added as arbiter for the data volume
( ssd-samsung )
So the plan is to have "engine"  scaled in a full replica 3,  and
"ssd-samsung" scalled in a replica 3 arbitrated.

[ovirt-users] Single instance scaleup.

[Leo David]

Hello Everyone,
Can someone help me to clarify this ?
I have a single-node 4.2.8 installation ( only two gluster storage domains
- distributed  single drive volumes ). Now I just got two identintical
servers and I would like to go for a 3 nodes bundle.
Is it possible ( after joining the new nodes to the cluster ) to expand the
existing volumes across the new nodes and change them to replica 3
arbitrated ?
If so, could you share with me what would it be the procedure ?
Thank you very much !

Leo

[ovirt-users] Re: Arbiter brick disk performance

[Leo David]

Thank you so much Strahil ! Yes, this would be the setup. Basically, I will
equip the 3rd node with only some consumer grade ssds to have the arbiter
metadata for all the volumes, while having the 1st and 2nd nodes equipped
with proper dc grade disks for both spinning and ssd volumes. This will
drastically reduce costs...
Thank you !

[Leo David]

Thank you very much Strahil, very helpful. As always. So I would equip the
3rd server and alocate one small ( 120 - 240gb) consumer grade ssd for each
of the gluster volume, and at volume creation, to specify the small ssds as
the 3rd brick.
Do it make sense ?
Thank you !

[ovirt-users] Arbiter brick disk performance

[Leo David]

Hello Everyone,
I need to look into adding some enterprise grade sas disks ( both ssd
and spinning  ),  and since the prices are not too low,  I would like to
benefit of replica 3 arbitrated.
Therefore,  I intend to buy some smaller disks for use them as arbiter
brick.
My question is, what performance ( regarding iops,  througput ) the arbiter
disks need to be. Should they be at least the same as the real data disks ?
Knowing that they only keep metadata, I am thinking that will not be so
much pressure on the arbiters.
Any thoughts?

Thank you !

[ovirt-users] Replica 3 distribute-replicated - data placement and fault tolerance

[Leo David]

Hello Everyone,
I did some fio performance tests on a particular vm and I have noticed
things that I do not understand regarding how data is placed along the
bricks. I am sure this is a lack of knowledge, but I would really
appreciate any help in understanding this, I did a bit of research on the
internet,  but just could't find something relevant.
I have one replica 3 distributed-replicated arbitrated volume, across 18
bricks ( 9 nodes, 2 jbods per node ).
The volume was created as:
node1 - brick1, node-2, brick1,.node9-brick1, node1 - brick2, node-2,
brick2,.node9-brick2
As far as i've understood,  under the hood there are sets of 3 times
replicated data ( subvolumes ) which are assigned to the first 3 bricks,
next set of replicated data to the next set of 3 bricks,  and so on..
Now, I have this testing vm runign one node one.
When I've started the fio test, i've noticed incresed gluster traffic from
node 1 to node2,4 and 5
So I assumed that the vm disk is data resides on a subvolume allocated to
bricks from these hosts.
Then I have migrated the vm on node 2, and did the same test. Now the
increased treffic is generated from node2 to node1, 4, and 5..
What I do not understand is:
 - why gluster client ( ovirt host ) is sending data to  3 bricks if the
volume is arbitrated - shouldn't it send only to 2 of them ?
- why are there 4 brick implicated in this subvolume
- what would it be the fault tolerance level in this setup ,ie: how many
hosts can I take down and still having the volume serving IO requests; can
they be random ?
I am sorry for my lack of knowledge,  I am just trying to understand what
is happening so I can deploy a decent proper setup of an hci environment.
Thank you,
Leo

[ovirt-users] Re: Importing existing GlusterFS

[Leo David]

In this case you might want to create dedicated gluster volumes for oVirt
and add them as new storage domains. Not sure about the performance though.

Than you !
Indeed, increasing the traffic it is a very good point...

[ovirt-users] Gluster arbiter volume storage domain - change

[Leo David]

Hi Everyone,
I have wrongly configured the main gluster volume ( 12 identical 1tb ssd
disks, replica 3 distributed-replicated, across 6 nodes - 2 per node ) with
arbiter one.
Oviously I am wasting storage space in this scenario with the arbiter
bricks, and I would like to convert the volume to non-arbitrated one, so
having all the data evenly spreaded across all the disks.
Considering the the storage is being used by about 40 vms in production,
what would it be the steps, or is there any chance to change the volume
type to non-arbitrated on the fly and then rebalance ?
Thank you very much !

[Leo David]

Thank you Alex !
I will try these performance settings.
If someone from the dev guys could validate and recommend those as a good
standard configuration, it would be just great.
If they are ok,  wouldn't be a nice to have them applied from within UI
with the "Optimize for VirtStore"  button ?
Thnak you !

[Leo David]

Hi,
Thank you Alex, I was looking for some optimisation settings as well, since
I am pretty much in the same boat, using ssd based replicate-distributed
volumes across 12 hosts.
Could anyone else (maybe even from from ovirt or rhev team) validate these
settings or add some other tweaks as well, so we can use them as standard ?
Thank you very much again !

[ovirt-users] Controller recomandation - LSI2008/9265

[Leo David]

Hi Everyone,
For a hyperconverged setup started with 3 nodes and going up in time up to
12 nodes, I have to choose between LSI2008 ( jbod ) and LSI9265 (raid).
Perc h710 ( raid ) might be an option too, but on a different chassis.
There will not be many disk installed on each node, so the replication will
be replica 3 replicated-distribute volumes across the nodes as:
node1/disk1  node2/disk1  node3/disk1
node1/disk2  node2/disk2  node3/disk2
and so on...
As i will add nodes to the cluster ,  I intend expand the volumes using the
same rule.
What would it be a better way,  to used jbod cards ( no cache ) or raid
card and create raid0 arrays ( one for each disk ) and therefore have a bit
of raid cache ( 512Mb ) ?
Is raid caching a benefit to have it underneath ovirt/gluster as long as I
go for "Jbod"  installation anyway ?
Thank you very much !

The engine eventually went up,  and i could login into the UI. Here, i've I
have found an additional stopped vm called "external-HostedEngineLocal" - i
assume the playbook didnt managed to delete it.
I just don't know what to say, if this installation is reliable considering
it is a fresh installation from official iso image...
Do you think it would be better to wait for the next release when hopefully
gluster 5.5 will be integrated too ?

Thank very much for your answers !

Just to loop in,  i've forgot to hit "Reply all"

I have deleted everything in the engine gluster mount path, unmounted the
engine gluster volume ( not deleted the volume ) ,  and started the wizard
with "Use already configured storage". I have pointed to use this gluster
volume,  volume gets mounted under the correct path, but installation still
fails:

Should I perform an "engine-cleanup",  delete lvms from Cockpit and start
it all over ?
Did anyone successfully used this particular iso image
"ovirt-node-ng-installer-4.3.2-2019031908.el7.iso" for a single node
installation ?
Thank you !

It just does not make sense to not be able to install from scratch a fresh

I have just installed a new fresh node,   and triggered the single instance
hyperconverged setup. It seems it fails at the hosted engine final steps of

I have used the ovirt-node-ng-installer-4.3.2-2019031908.el7.iso. So far,
I am unable to deploy oVirt single node Hyperconverged...
Any thoughts ?

[Leo David]

Thank you Simone.
I've decides to go for a new fresh install from iso, and i'll keep posted
if any troubles arise. But I am still trying to understand what are the
services that mount the lvms and volumes after configuration. There is
nothing related in fstab, so I assume there are a couple of .mount files
somewhere in the filesystem.
Im just trying to understand node's underneath workflow.

[ovirt-users] HE - engine gluster volume - not mounted

[Leo David]

Hello Everyone,
Using 4.3.2 installation, and after running through HyperConverged Setup,
at the last stage it fails. It seems that the previously created "engine"
volume is not mounted under "/rhev" path, therefore the setup cannot finish
the deployment.
Any ideea which are the services responsible of mounting the volumes on
oVirt Node distribution ? I'm thinking that maybe this particularly one
failed to start for some reason...
Thank you very much !

[ovirt-users] Re: [Gluster-users] Announcing Gluster release 5.5

[Leo David]

Olaf, thank you very much for this feedback, I was just about to upgrade my
12 nodes 4.2.8 production cluster. And it seem so that you speared me of a
lot of trouble.
Though, I thought that 4.3.1 comes with gluster 5.5 which has been solved
the issues, and the upgrade procedure works seemless.
Not sure now how long or what oVirt version to wait for before upgrading my
cluster...

[ovirt-users] Re: VM disk corruption with LSM on Gluster

[Leo David]

Hi,
I can confirm that after setting these two options, I haven't encountered
disk corruptions anymore.
The downside, is that at least for me it had a pretty big impact on
performance.
The iops really went down - performing  inside vm fio tests.

Hi everyone,
I have seen a lot of threads here regarding 4.3.x release regarding
problems a different layers, most of them related to underneath gluster
storage.
I would do an upgrade though, thus benefiting the new added features.
My thoughts would be:
1. did anyone succesfully went through this process, any problems occured
during of after the upgrade ?
2. any sincere recomandation like "if it works don't fix it" considering
the platform is running in production ?
I would really apreciate your oppinion.
Thank you very much !

[ovirt-users] Re: Dell OMSA on oVirt node

[Leo David]

Thank you guys !
Wow... this complicates the things, since reinstalling the hosts with
centos instead of oVirt node distribution would give me a bit of headache.
The dell hosts are already running in production.
I think it would be really nice if standard node would support installing
management software for well known brands like dell, hp, lenovo,
supermicro, etc... I am sure we cannot track every server brand in the
world, but in realitty there are just a couple of them most spreaded across
ovirt node installations.
I will try to see what I can do, although I am a bit afraid to not break
the os somehow...

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
Obviously there are conflicts,  but the server being on production,  I
would not mess around with the packages and trying to solve the conflicts.

Any thoughts ?
Thank you very much,

Leo

[ovirt-users] Bandwidth problem

[Leo David]

Hello Everyone,
I have 10Gb connections setup for all the hosts in the cluster, for both
management/vm  and gluster traffic ( separate network cards )
The problem is that i just cannot pass 1Gb/s traffic between vms ( even
between vms running on the same hosts ! - which makes the things more
weird... ). Traffic measured by using iperf tool.
Is there a way I can check waht could be the problem ? Network card type,
vm drivers,  any suggestion ? I just do not know where to look for a
possible cause.
Thank you very much !

Leo

[ovirt-users] Re: Mounting CephFS

[Leo David]

Thank you,
I am trying to migrate a vm that has its disks on cephfs ( as posix domain
- mounted on all hosts ),  and it does not work. Not sure if this is
normal,  considering the vm disks being on this type of storage.  The error
logs in engine are:

2019-03-02 13:35:03,483Z ERROR

Any thoughts ?

[ovirt-users] Re: Mounting CephFS

[Leo David]

Thank you Strahil, yes thought about that too, I'll give it a try.
Now ( to be a bit offtopic ), it seems that I can't live migrate the vm,
even thought the cephfs mountpoint exists on all the hosts.
Could it be the fact that the storage type is "posix" and live migration
not being possible ?

Thank you !

[ovirt-users] Mounting CephFS

Any thoughts on this,  what could it be wrong with the options field ?
Using oVirt 4.3.1

[ovirt-users] Re: VM poor iops

[Leo David]

Thank you Sahina, I'm in that conversation too :).
On the other hand...
In this case, setting this option on, would only make sense in multi-node
setups, and not in single instance ones, where we only have one hypervisor
accsessing the volume.
Please correct me if this is wrong.
Have a nice day,

Leo

[Leo David]

Hi,
Is the performance.strict-o-direct=on a mandatory option to avoid data
inconsistency, although it has a pretty big impact on volume iops
performance?
Thank you !

Thank you Krutika,
Does it mean that turning that setting off, i have chances to get into data

It seems to have a pretty big impact on vm performance..

[ovirt-users] Gluster - performance.strict-o-direct and other performance tuning in different storage backends

[Leo David]

Hello Everyone,
As per some previous posts,  this "performance.strict-o-direct=on" setting
caused trouble or poor vm iops.  I've noticed that this option is still
part of default setup or automatically configured with
"Optimize for virt. store" button.
In the end... is this setting a good or a bad practice for setting the vm
storage volume ?
Does it depends ( like maybe other gluster performance options ) on the
storage backend:
- raid type /  jbod
- raid controller cache size
I am usually using jbod disks attached to lsi hba card ( no cache ). Any
gluster recommendations regarding this setup ?
Is there any documentation for best practices on configurating ovirt's
gluster for different types of storage backends ?
Thank you very much !

Have a great week,

Leo

Hi Everyone,
I have this challange where I need to rollback a couple  of vms to a

It there a way to configure this feature somehow in the UI ?

Just thinking
Maybe different options where configured to the volumes during update, that
could make them unstable ?

[ovirt-users] oVirt upgrade to specific version

[Leo David]

Hi,
I have a running 4.2.7 hci cluster which I would upgrade to 4.2.8.
If I do this in the standard manner (yum update in engine vm and then the
nodes from engine UI) I assume it will go to 4.3, which I would rather
avoid for now.
Is there a way for getting it updated strictelly to 4.2.8 ?

Thanks,

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Thank you Victor.
Yes, I have the latest guest-tools installed, and the problem is that after
configuring the vm by using virsh and reboot,  the configuration reverts to
defaults:

  
  
  
  
  
  
  
  
  

So my added changes are not loaded at vm boot.
 I am sure this is an oVirt spicific behavior, but i just can;t find it out
how to make this persistent.

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Hi Everyone,
Any thoughts on this ?
It seems that audio streaming is affected as well, and bandwidth is not an
issue in this case.
'm thinking that maybe if I just just disable compression on spice,  things
would get a bit better...maybe.
Thank you !

Also, i would test i different storage type (maybe a quick nfs data domain
) and see if problem persist with that one too.

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Thank you so much Victor !
Anyone, any ideea how could I disable video compression for spice console
on particular vms ?
I am trying to implement an "almost" full desktop experience with an oVirt
based vdi environment.
And besides the Windows10 spice issues ( which are the main cause of this
thread ), it seems that Windows 7 is affected too by the multimedia playing
perspective. Which makes a total blocker on project implementation
Any suggestions/ similar experiences ?
Thank you very much and have a nice day !

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Hi,
"This enable host-side streaming, are you sure you want it?"
Not sure yet, but i would at least disable compression, video playing seems
to be pretty poor, and crackling ( youtube, etc )

"AFAIK, if virsh edit exits without issue, you need to shutdown
the vm and then start it again"
I did that,  and when the vm comes back on,  my changes are not there
anymore

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Hi,

I am trying to disable video compression as per this thread:
https://lists.ovirt.org/pipermail/users/2017-January/078753.html

The thing is that I just can't figure out where to place the following:







If I attempt to edit vm properties by using virsh and add these custom
settings, the configuration file gets overwritten once the vm reboots.

Any suggestions?

Thank you,

Leo

In vdsm I can't find something related to this operation...
It feels like is not getting the luns from the target,  although from a
different client ( windows machine) i can successfully connect and map the
lun.

[ovirt-users] Issues adding iscsi storage domain

[Leo David]

Hello everyone,
Trying to setup an iscsi target as a storage domain,  and it seems not to
be possible.
Discovered the hosts,  the targets are displayed.
Selected one target, clicked the "Login" arrow, spinner runs a bit ,  and
the arrow gets grayed out.
But no LUNs are displayed, to select from.
>From this step,  I can't go further,  if I hit "OK" nothing happends.
Just as a thoughtssh into the ovirt node used as initiator, and lsblk
command shows the block device as present.
So i have to cancel the "New Domain" windows without being able to add the
domain,  but that iscsi block device still remains present on the hosts.

Using 4.2.8

Any thoughts ?

Thank you very much !

Leo

[ovirt-users] Hyperconverged setup - storage architecture - scaling

[Leo David]

Hello Everyone,
Reading through the document:
"Red Hat Hyperconverged Infrastructure for Virtualization 1.5
 Automating RHHI for Virtualization deployment"

Regarding storage scaling,  i see the following statements:





*2.7. SCALINGRed Hat Hyperconverged Infrastructure for Virtualization is
supported for one node, and for clusters of 3, 6, 9, and 12 nodes.The
initial deployment is either 1 or 3 nodes.There are two supported methods
of horizontally scaling Red Hat Hyperconverged Infrastructure for
Virtualization:*


*1 Add new hyperconverged nodes to the cluster, in sets of three, up to the
maximum of 12 hyperconverged nodes.*


*2 Create new Gluster volumes using new disks on existing hyperconverged
nodes.You cannot create a volume that spans more than 3 nodes, or expand an
existing volume so that it spans across more than 3 nodes at a time*




*2.9.1. Prerequisites for geo-replicationBe aware of the following
requirements and limitations when configuring geo-replication:One
geo-replicated volume onlyRed Hat Hyperconverged Infrastructure for
Virtualization (RHHI for Virtualization) supports only one geo-replicated
volume. Red Hat recommends backing up the volume that stores the data of
your virtual machines, as this is usually contains the most valuable data.*
--

Also  in oVirtEngine UI, when I add a brick to an existing volume i get the
following warning:

*"Expanding gluster volume in a hyper-converged setup is not recommended as
it could lead to degraded performance. To expand storage for cluster, it is
advised to add additional gluster volumes." *

Those things are raising a couple of questions that maybe for some for you
guys are easy to answer, but for me it creates a bit of confusion...
I am also referring to RedHat product documentation,  because I  treat
oVirt as production-ready as RHHI is.

*1*. Is there any reason for not going to distributed-replicated volumes (
ie: spread one volume across 6,9, or 12 nodes ) ?
- ie: is recomanded that in a 9 nodes scenario I should have 3 separated
volumes,  but how should I deal with the folowing question

*2.* If only one geo-replicated volume can be configured,  how should I
deal with 2nd and 3rd volume replication for disaster recovery

*3.* If the limit of hosts per datacenter is 250, then (in theory ) the
recomended way in reaching this treshold would be to create 20 separated
oVirt logical clusters with 12 nodes per each ( and datacenter managed from
one ha-engine ) ?

*4.* In present, I have the folowing one 9 nodes cluster , all hosts
contributing with 2 disks each  to a single replica 3 distributed
replicated volume. They where added to the volume in the following order:
node1 - disk1
node2 - disk1
..
node9 - disk1
node1 - disk2
node2 - disk2
..
node9 - disk2
At the moment, the volume is arbitrated, but I intend to go for full
distributed replica 3.

Is this a bad setup ? Why ?
It oviously brakes the redhat recommended rules...

Is there anyone so kind to discuss on these things ?

Thank you very much !

Leo

[ovirt-users] Re: Deploying single instance - error

[Leo David]

Hi,
It seems so that I had to manually add the sections, to make the scrip
working:
[diskcount]
12
[stripesize]
256

It looks like ansible is still searching for these sections regardless
that I have configured "jbod"  in the wizard...

Thanks,

Leo

[ovirt-users] Vdo based storage domain

[Leo David]

Hi everyone,
I have read and tried to understand how vdo works, and it seems pretty
impressive, but i feel like i am missing something.
At the end of the day, my question is:
Can I entirelly rely on the 10 times increased usable space ?
As and example, I have created a 4.8tb volume based on 3x480gb samsung
sm863a enterprise ssd devices. (full replica 3).
Should I be confident that I can use 4.8tb for my storage domain (vms data
store) without concerning about data repetabilitty in the future ?
I am just trying to think as an end-user consumer that cannot predict if
data that will be written to the device will be compresable or not, and
only see 4.8tb as trully usable space.
Any thoughts, any experience to share ?
Im sorry if my question sounds noob, but i'm just trying to get under end
user's hat.
Thank you very much,

Have a good day !
Leo

[ovirt-users] Re: External private ova / image repository

[Leo David]

Hi,
Any thoughts on these, any ideeas ?
Maybe buying a payed cinder service from a cloud provider would do the job,
or implement some sort of image repo in my datacenter and expose it over
the web with some form of auth ?
Any case scenarios ?

Thank you very much !

I am not sure what would it be the pieces needed to have an external repo
that I can manage and use at the client site for downloading customized

[ovirt-users] VDO volume - storage domain size

[Leo David]

Hello Everyone,
I'm I trying to benefit of vdo capabilities,  but it seems that I don;t
have too much luck with this.
I have both created a vdo based gluster volume usign both following methods:
- at hyperconverged wizard cluster setup by enabling compression per device
- after installation, by creating a new gluster volume and enabling
compression

In both cases,  I end up with a real device size gluster volume/storage
domain, although the vdo's appear in node's cockpit UI as being 10 times
then physical device.

ie: 3 nodes,  each having 1 x 900GB ssd device, turns into 9t device vdo
device per host, but the storage domain (gluster  replica 3 ) ends up as
being 900GB   .
Am I missing something ,  or maybe doing something wrong?
Thank you very much !

Leo

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Thank you very mucjh,  and sorry for being so lazy to search for that rpm
by myself. Somehow, fedora rpms missed from my mind.
Oh boy, it requires a lot of packages. Do you think would it be a good idea
to temporarily install fedora repos, do the yum installation to get the
dependencoes too and then disable the repo ? I am thinking to not break the
ovirt node installation.

 yum localinstall spice-server-0.14.1-1.fc30.x86_64.rpm
Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist,
package_upload, product-id, search-disabled-repos, subscription-manager,

This system is not registered with an entitlement server. You can use
subscription-manager to register.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Cannot upload enabled repos report, is this client registered?

[Leo David]

Thank you very much Victor,
Is there a rpm that I can easily install on all the nodes, or will I need
to build that version from sources ?

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Leo David]

Thank you very much !

I have modified /etc/ovirt-engine/osinfo.conf.d/00-defaults.properties file
and added the last line

# Windows10x64
os.windows_10x64.id.value = 27
os.windows_10x64.name.value = Windows 10 x64
os.windows_10x64.derivedFrom.value = windows_8x64
os.windows_10x64.productKey.value =
os.windows_10x64.resources.maximum.ram.value = 2097152
os.windows_10x64.cpu.unsupported.value = conroe, opteron_g1
os.windows_10x64.sysprepPath.value =
${ENGINE_USR}/conf/sysprep/sysprep.w10x64
*os.windows_10x64.devices.display.vramMultiplier.value = 2*

The vm has the "Windows10x64" profile configured

Restarted the ovirt-engine vm, powered on the Windows 10 vm. Not any
difference...The console is very slow, almost unusable.

Also, tried to upgrade spice-server on the node, but it seems that there
aeno updates available. At the moment, it is installed:
 spice-server.x86_64   0.14.0-2.el7_5.3

Any thoughts ?

Thank you !

Leo
