Well, the only feature which seem to be missing (at least for some
people) is to comment alongside the pages, but you can still make
reviews in PRs.

I think these last few month there is more people around and it is more
reactive, and there's much less lingering PRs.

Also I have no idea about how promoting people to merge power is done. I
think there is quite an unfair side of the story: if you're from RH then
you can get admin rights on the spot but external contributors I guess
don't guess this very easily. I didn't any procedure to apply for this.

That's a very good point. A colleague working on OpenStack stuff was
telling me this works much better to commit doc alongside doc in the
same PR.

Also the project promotion and technical docs would probably benefit
from being separated, so that giving permissions to people would not
affect the main portal and messaging if they just need to write on
features/config/install/…

Same.

With GH and Gerrit using external auth I think anyone is able to contribute.



So to come back to Markdown stuff. People in charge of messaging do not
want an ugly portal, and even a simple one means a little bit of CSS.
Also there are news/blog entries, so another feature which needs
slightly more power. Also search is a nice feature too. So we're using
Middleman, that's not perfect at all, version 3 is a failure, and we
were looking at a new tool, Jekyll, and it's being tested on another
project.

Jekyll is the tool developed by GH and this rejoins Edward's proposal.

Nevertheless I totally disagree about going to the bare minimum. If you
want to get a clean, readable and coherent documentation you will still
end-up having a few editorial rules, templates… to follow and yes you
need to get up to it and learn. With content of this size if anyone just
decide to have his own flavor it will be a mess very soon.

Also we already have piles of content so this means some work to
migrate. Markdown is not a standard so depending on the generator you
use the syntax may differ slightly. There's some custom Ruby code we
need to get rid of too. So that's a real project and unfortunately the
person who was working in this direction is no more in the project. Once
I'm more acquainted to Jekyll and i still think this could be a nice
replacement, then I'll try to get some time to help on this front.

Anyway to get out of the current system we first need to remove all the
custom Ruby code around Middleman and maybe other ugly things, so…
patches are welcome!

[ovirt-users] Expand Hosted-Engine Disk Space

[Adam Chesterton]

Hi All,

I am encountering a situation where the hosted engine for my test setup has
run out of space. It only has 10GB configured, which was an oversight on my
part when first deploying it. All storage is Gluster replica 3 (4 volumes;
engine, vm, iso, export) and I have plenty of available space. My oVirt
version is currently at 4.1.1.

I've spent time looking for a solution to expand the disk size, but without
luck so far. Most items I've found from previous list emails are from the
3.5 days, and seem to indicate that by 3.6+ you should be able to modify
the hosted engine from within the oVirt Admin Web Console. However, when I
try to expand the hosted engine disk I get an error that the VM is not
managed by the engine, so obviously that functionality is not yet
implemented.

So, my question is; what is the current process to expand the hosted engine
disk?

Regards,
Adam Chesterton

[ovirt-users] vm freezes when using yum update

In our environment we have 2 hosts 1 NFS server and 1 ovirt engine server. The 
NFS server provides storage to the VMs in the hosts.
I can create new VMs and install os but once i do something like yum update the 
VM freezes. I can reproduce this every single time I do yum update.
what information/log files should I provide you to trubleshoot this?

Re: [ovirt-users] HostedEngine VM not visible, but running

[cmc]

Hi Jenny/Martin,

Any idea what I can do here? The hosted engine VM has no log on any
host in /var/log/libvirt/qemu, and I fear that if I need to put the
host into maintenance, e.g., to upgrade it that I created it on (which
I think is hosting it), or if it fails for any reason, it won't get
migrated to another host, and I will not be able to manage the
cluster. It seems to be a very dangerous position to be in.

Thanks,

Cam

Re: [ovirt-users] HostedEngine VM not visible, but running

Thanks Martin. The hosts are all part of the same cluster.

I get these errors in the engine.log on the engine:

The sanlock.log reports conflicts on that same host, and a different
error on the other hosts, not sure if they are related.

And this in the /var/log/ovirt-hosted-engine-ha/agent log on the host
which I deployed the hosted engine VM on:

MainThread::ERROR::2017-06-19

Failed extracting VM OVF from the OVF_STORE volume, falling back to
initial vm.conf

I've seen some of these issues reported in bugzilla, but they were for
older versions of oVirt (and appear to be resolved).

I will install that package on the other two hosts, for which I will
put them in maintenance as vdsm is installed as an upgrade. I guess
restarting vdsm is a good idea after that?

 The engine is supposed to see the hosted engine storage domain and import 
 it
 to the system, then it should import the hosted engine vm.

 Can you attach the agent log from the host
 (/var/log/ovirt-hosted-engine-ha/agent.log)
 and the engine log from the engine vm (/var/log/ovirt-engine/engine.log)?

 Thanks,

No, you don't need to do any of that. Just executing volume-set commands is
sufficient for the changes to take effect.

No. It's just that in the internal testing that was done here, increasing

 Hi folks,

 I have 3x servers in a "hyper-converged" oVirt 4.1.2 + GlusterFS 3.10
 configuration. My VMs run off a replica 3 arbiter 1 volume comprised of
 6 bricks, which themselves live on two SSDs in each of the servers (one
 brick per SSD). The bricks are XFS on LVM thin volumes straight onto the
 SSDs. Connectivity is 10G Ethernet.

 Performance within the VMs is pretty terrible. I experience very low
 throughput and random IO is really bad: it feels like a latency issue.
 On my oVirt nodes the SSDs are not generally very busy. The 10G network
 seems to run without errors (iperf3 gives bandwidth measurements of >=
 9.20 Gbits/sec between the three servers).

 To put this into perspective: I was getting better behaviour from NFS4
 on a gigabit connection than I am with GlusterFS on 10G: that doesn't
 feel right at all.

 My volume configuration looks like this:

 Volume Name: vmssd
 Type: Distributed-Replicate
 Volume ID: d5a5ddd1-a140-4e0d-b514-701cfe464853
 Status: Started
 Snapshot Count: 0
 Number of Bricks: 2 x (2 + 1) = 6
 Transport-type: tcp
 Bricks:
 Brick1: ovirt3:/gluster/ssd0_vmssd/brick
 Brick2: ovirt1:/gluster/ssd0_vmssd/brick
 Brick3: ovirt2:/gluster/ssd0_vmssd/brick (arbiter)
 Brick4: ovirt3:/gluster/ssd1_vmssd/brick

 I would really appreciate some guidance on this to try to improve things
 because at this rate I will need to reconsider using GlusterFS

Hi Krutika,

Thanks for your input. I have yet to run any benchmarks, but I'll do
that once I have a bit more time to work on this.

I've tweaked the options as you suggest, but that doesn't seem to have
made an appreciable difference. I admit that without benchmarks it's a
bit like sticking your finger in the air, though. Do I need to restart
my bricks and/or remount the volumes for these to take effect?

I'm actually running GlusterFS 3.10.2-1. This is all coming from the
CentOS Storage SIG's centos-release-gluster310 repository.

Thanks again.

Re: [ovirt-users] [Gluster-users] Very poor GlusterFS performance

[mabi]

Dear Krutika,

Sorry for asking so naively but can you tell me on what factor do you base that 
the client and server event-threads parameters for a volume should be set to 4?

Is this metric for example based on the number of cores a GlusterFS server has?

I am asking because I saw my GlusterFS volumes are set to 2 and would like to 
set these parameters to something meaningful for performance tuning. My setup 
is a two node replica with GlusterFS 3.8.11.

Best regards,
M.

Couple of things:
1. Like Darrell suggested, you should enable stat-prefetch and increase client 
and server event threads to 4.
# gluster volume set  performance.stat-prefetch on
# gluster volume set  client.event-threads 4
# gluster volume set  server.event-threads 4

2. Also glusterfs-3.10.1 and above has a shard performance bug fix - 
https://review.gluster.org/#/c/16966/

With these two changes, we saw great improvement in performance in our internal 
testing.

Do you mind trying these two options above?

Hi folks,

I have 3x servers in a "hyper-converged" oVirt 4.1.2 + GlusterFS 3.10
configuration. My VMs run off a replica 3 arbiter 1 volume comprised of
6 bricks, which themselves live on two SSDs in each of the servers (one
brick per SSD). The bricks are XFS on LVM thin volumes straight onto the
SSDs. Connectivity is 10G Ethernet.

Performance within the VMs is pretty terrible. I experience very low
throughput and random IO is really bad: it feels like a latency issue.
On my oVirt nodes the SSDs are not generally very busy. The 10G network
seems to run without errors (iperf3 gives bandwidth measurements of >=
9.20 Gbits/sec between the three servers).

To put this into perspective: I was getting better behaviour from NFS4
on a gigabit connection than I am with GlusterFS on 10G: that doesn't
feel right at all.

My volume configuration looks like this:

Volume Name: vmssd
Type: Distributed-Replicate
Volume ID: d5a5ddd1-a140-4e0d-b514-701cfe464853
Status: Started
Snapshot Count: 0

I would really appreciate some guidance on this to try to improve things
because at this rate I will need to reconsider using GlusterFS altogether.

Could you provide the gluster volume profile output while you're running your 
I/O tests.
# gluster volume profile  start

to start profiling

# gluster volume profile  info
for the profile output.

Hi Jenny,

Does ovirt-hosted-engine-ha need to be installed across all hosts?
Could that be the reason it is failing to see it properly?

Re: [ovirt-users] hosted-engine network

[Arsène Gschwind]

Hi Yanir,

We had our oVirt Engine running on a HW server so we decided to move it 
to hosted-engine. For this I've followed the Howto at 
http://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Metal_to_an_EL-Based_Self-Hosted_Environment/.


The Hosted-Storage is located on a FC SAN LUN.

Please find attached the setup log.

Tanks a lot.

Arsène

It should be in one of the directories on your storage domain:

To see which one you can run the following command:

vdsm-client Volume getInfo volumeID= imageID=
storagedomainID= storagepoolID=

the storage domain id is: cd1f6775-61e9-4d04-b41c-c64925d5a905
the storage pool id can be found using: vdsm-client StorageDomain
getInfo storagedomainID=cd1f6775-61e9-4d04-b41c-c64925d5a905

The volume that has "description":
"HostedEngineConfigurationImage" is the one you are looking for.
Untar it and it should contain the original vm.conf which was
used to start the hosted engine.

[ovirt-users] Hosted Engine stopped on Good Agent -> 4.1.1

[Matt .]

Hi Guys,


I have moved my environment from datacenter to datacenter and it seems
that my agents are doing "strange" after it.

The engine starts but stops after being initialized and the agent.log
doesn't show any errors. This happens on 4.1.1

One of the hosts which is a HE host has been upgraded to 4.1.2 to see
what happens there and when I want to start the hosted engine there I
get:

# hosted-engine --vm-start
Unable to read vm.conf, please check ovirt-ha-agent logs


The HE storage is mounted well on the 4.1.1 host which doesn't mount
the other NFS storages, but the 4.1.2 host has all storages (NFS)
mounted which is kinda strange if you ask me.

Where should I start as this cluster has been moved earlier without any issue.


Thanks,

Matt

 You can get it from our GitHub [1]; the play store will be upgraded
 after considered stable.

 The main feature of this release is a support for managing multiple
 oVirt installations from one moVirt.

Right now I installed it only on my smartphone (Samsung S7 with Android
7.0) and was able to connect to a single host, hosted engine environment
based on oVirt 4.1.
The speed of actions inside application seems quite good! Even connected
through VPN to a slow link, but passing from one information to the other
was quite immediate... very nice!
What tested:
- VM powered off, I power on it and I see its events section populated only
by the new power on event
- verified spice console (both with a VM in text mode and one with graphic
display)
- verified create snapshot and delete snapshot for a powered on VM

So far so good.
I'm going to install also to a tablet with access to more than one
environment and test connection to 2 different infrastructures...

Re: [ovirt-users] [ovirt-devel] Lowering the bar for wiki contribution?

[Martin Sivak]

> I think we need a wiki for this, instead of reinventing one :-)

Really? And ending in the same mess we had before? No thanks.

Other big ans successful [1] (single component) projects have docs/
directory and documentation and design reviews are integral part of
code review. That way you can atomically reject/accept changes to code
and docs together. We can't easily do it this way as we have multiple
cooperating components, but we should try to get close.

> We have a builtin markdown based wiki in the ovirt site github project.

Yes we do, but we do not have commit rights. And internal technical
documentation and _design_ pages need to be a bit closer to the source
otherwise nobody will want to touch them.

> For discussion, we have the mailing list and other channels like bluejeans
> and irc.

For informal yes. But formal proposals and final design documentation
are something different.

And don't let me started on the theoretical open aspect of our
project.. do we want more contributors or not? Can we afford
artificial barriers? Is somebody from general public allowed to
contribute ideas?

Gerrit / Github give everybody the power to easily see all currently
considered (open) projects and review them using the same interface we
use for our daily work! This way any team can catch conceptual issues
with other teams' projects. Searching through email threads is nowhere
near the same experience.
