[ovirt-users] Planning out oVirt Self-Hosted Engine on Gluster (oVirt 3.6.x / Gluster 3.7.5)

[Willard Dennis]

Hi all,

Back to trying out the latest oVirt with latest Gluster, and wanting to do a 
self-hosted Engine setup. I am reading the instructions I found on the 
following pages:

http://www.ovirt.org/Features/Self_Hosted_Engine_Gluster_Support 


http://www.ovirt.org/QA:TestCase_Hosted_Engine_External_Gluster_Support 


I have the requisite Gluster volume all ready to go:

[root@ovirt-node-01 ~]# gluster volume info engine

Volume Name: engine
Type: Distributed-Replicate
Volume ID: 974c9da4-b236-4fc1-b26a-645f14601db8
Status: Started
Number of Bricks: 2 x 3 = 6
Transport-type: tcp
Bricks:
Brick1: ovirt-node-01:/gluster_brick1/engine_brick
Brick2: ovirt-node-02:/gluster_brick2/engine_brick
Brick3: ovirt-node-03:/gluster_brick3/engine_brick
Brick4: ovirt-node-01:/gluster_brick3/engine_brick
Brick5: ovirt-node-02:/gluster_brick4/engine_brick
Brick6: ovirt-node-03:/gluster_brick5/engine_brick
Options Reconfigured:
server.allow-insecure: on
storage.owner-gid: 36
storage.owner-uid: 36
auth.allow: *
network.ping-timeout: 10
cluster.server-quorum-type: server
cluster.quorum-type: auto
network.remote-dio: enable
cluster.eager-lock: enable
performance.stat-prefetch: off
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off

The one question I have is, should it be mounted or not? I currently do have it 
mounted on each host (example off one of my oVirt hosts):

localhost:/engine  1.9T   65M  1.9T   1% /data/ovirt/engine

Will this interfere with the running of "hosted-engine —deploy”? Kindly advise.

Thanks,
Will___

, does it exist any way to do the same with ovirt hosts? (e.g. vlan at 
the bridge level and untagged by the nics vm themselves)




By default vlan interfaces come untagged to vms. This is normal setup.

I guess you want to pass the vlan trunk up to the vm's nic? (multiple 
vlans to vm)


I don't know any way of doing that with ovirt but it would be interesting.
I guess you would need something like openvswitch but I don't know if it 
will cooperate well with ovirt.

I expected storage to be configured inside admin web portal but apparently

I configured the storage domain part as NFS, pointing

Reading page at
http://www.ovirt.org/Features/Self_Hosted_Engine

it is not clear to me what to do next if I want for example keep a single
host with its sh engine as a replacement concept of what before was
all-in-one... and start creating VMs

Output of my web admin page:
https://drive.google.com/file/d/0BwoPbcrMv8mva3UyMTFDbHdsN3c/view?usp=sharing

Also, I didn't restart my hypervisor yet.
WHat should be the shutdown procedure? SImply run shutdown on hypervisor or
1) shutdwn engine vm
2) shutdown hypervisor
?

[ovirt-users] [SOLVED] Re: oVirt 3.6 disk speeds

[Julian De Marchi]

heya--

Issue came down to memory. The engine had 4095MB while my test VM had 
1048MB. Bumping up memory on my test VM saw speeds increase. In any 
case, 48 - 60MBs is my real speed. Time for iozone.


Hopefully this helps others.

the DC.

   - Dell Eql PS4210(Raid-6)
   - Dell R630
   - Dell N400 10GB switch

I have my 10GB interfaces bonded and in a port-channel. I have setup a
basic 3.6 oVirt self-hosted stack.

I am seeing some pretty big differences in disks speeds from the
self-hosted engine and a VM guest. Both are direct luns via iscsi from
the SAN on the 10GB port-channel. Normal network traffic does not go
over the 10GB.

On the engine I'm seeing this:

# dd if=/dev/zero of=~/testfile bs=1G count=1 oflag=dsync
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 1.58877 s, 676 MB/s

On a test VM I'm seeing this:

# dd if=/dev/zero of=~/testfile bs=1G count=1 oflag=dsync
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 22.0732 s, 48.6 MB/s

I have played with the disk drivers for my guest VM, changing between
drivers does not change the speed at all.

What ideas do you folks have for me to narrow down this slow down? I
don't really know where to start with this one. I also noticed that 3.6
does not yet have ovirt-guest-agent available.

I know DD is not the best test for disk speeds, but it works for what I
need right now, iozone will be next when I'm happy.

Many thanks!

Many thanks for the above script. I ran it on Ovirt manager. It worked. It

I rewrote the script in this way and ran it.

No error was given. I have no idea whether snapshot wad added or NOT by the
above script.

I can't display it.

*How to display it?  *

Then, *How to backup the VM with this snaphot? *

Then, finally* how to delete this snapshot? *to delete the snapshot,

I tried with below command. the did NOT worked.



*vm.snapshots.delete() *or
  *vm.snapshots.detach(*

 or
  *vm.snapshots.remove(*

I think I am have completed about 50% of this backup process. If you can
write down the  above steps, It would be very grateful.


I searched a whole lot. But , I still can't do it.

These are the links I came across.

https://github.com/laravot/backuprestoreapi/blob/master/example.py

http://www.ovirt.org/Testing/PythonApi#Create_a_Basic_Environment_using_ovirt-engine-sdk

this is your one

http://users.ovirt.narkive.com/Z29BQWAD/ovirt-users-python-sdk-attach-disk-snapshot-to-another-virtual-machine


Hmm,


*How to list the sanphot? *

*how to backup the VM with snapshot? *

*finally , how to remove this snapshot? *


Then. I think it will be OVER. Yesterday, I tried a lot.  but, NO success.

Hope to hear from you.

Not exactly "help" but AFAIK, even with 3.5, there is no live merging of 
snapshots so they can't be deleted unless the VM is down.  I know for large 
snapshots that have been around for awhile removing them can take some time too.


Others feel free to chime in...

If you know the name of the VM then you can find it, including its id,
doing a search:

https://engine.example.com/ovirt-engine/api/vms?search=name%3Dmyvm

If you prefer to use a script, which is probably the right thing, then
you can do something like this, using the Python SDK:

---8<---
#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(
url="https://engine.example.com/ovirt-engine/api;,
username="admin@internal",
password="**",
ca_file="/etc/pki/ovirt-engine/ca.pem",
debug=False
)

# Find the VM:
vm = api.vms.get(name="myvm")

# Print the id:

Once you have the VM you can create a snapshot like this:

---8<---
vm.snapshots.add(
params.Snapshot(description="My snapshot")
)
--->8---

You can also use the Java SDK, if you prefer Java.

look at:
https://engine.example.com/ovirt-engine/api/vms

it lists all the vms and shows both the VM name and it's ID

the correct address should be

Ok, I'll try.
So when bug solved, if I have a problem with the engine and for example I'm
not able to connect to it through ssh and/or web admin console, what other
means would I have to connect to it console and check (eg if it is in
kernel panic for any reason)?
During setup I was proposed to connect via remote-viewer via a temporary
password; I imagine this way is not usable after install, correct?

Ah, ok. I thought that the initial storage domain would have become the
first storage domain for general VMs purposes too...
So actually if on dedicated filesystem/device, it could be small in size,
say 5-10Gb if I use the appliance, correct?

OK.
In case I want to setup a single host with self hosted engine, could I
configure on hypervisor
a) one NFS share for sh engine
b) one NFS share for ISO DOMAIN
c) a local filesystem to be used to create then a local POSIX complant FS
storage domain
and work this way as a replacement of all-in-one?

Ok. And for starting all again, is this correct:

a) power on hypevisor
b) hosted-engine --set-maintenance --mode=none

other steps required?

The only thing is that I first ran
  hosted-engine --deploy
without putting the hostname of engine inside /etc/hosts of hypervisor and
it failed (see my first mail of the thread), I think without doing anything
(at least at engine VM level, I don't know if it created a cert...), but
generating an answer file.

And then I ran, as you suggested (with the warning you noted)
hosted-engine --deploy --config-append=answer_file

Inside log of first run
(ovirt-hosted-engine-setup-20151021151938-j4hy5g.log) I see

Any particular file or section in log files to cross check?
I can also start from scratch in case just to be sure that I don't get

Ehm if the engine VM is not responding you cannot use the engine to check
it.
But you have an HA agent that monitors it for you and can restart if needed.

You can also use ssh with the root password you set via cloud-init.

You can use

20GB is the minimum recommended value plus you need additional space for

Yes but c is just a workaround, using another external NFS share would help
a lot if in the future you plan to add o to migrate to a new server.

 I expected storage to be configured inside admin web portal but
 apparently I don't see anything already configured and also I don't see the

That ovirt-hosted-engine-setup attempt used /dev/loop0 and it got correctly
detached at the end.

2015-10-22 15:51:28 DEBUG

So that /dev/loop3 is probably just a leftover of one of your previous
attempts. I think you can safely remove it.

/api is deprecated [1]. Please use /ovirt-engine/api in all URLs.

IIUC it should still work, though.

The page above links also to a complete example (check "External
references" near the end). Did you check it?

You might also want to play with the examples in [2].

No, we have an open bug on that:
https://bugzilla.redhat.com/show_bug.cgi?id=1269768

You can try to manually import it in the mean time.

But hosted-engine storage domain can just contain the engine VM so you
still need to add a regular storage domain for other VMs.

It was used by hosted-engine-setup as a fake storage pool to bootstrap the
hosted-engine storage domain.
It shouldn't be there at the end.
Could you please attach hosted-engine-setup logs to let me check why it's
still there?

You have to setup your first regular data domain for other VMs: you can add
another NFS one.

The issue seams to be there:
we have an input request on host-deploy to have somebody explicitly
trusting the VDSM cert chain but of course, being an automated process,
nobody will respond and so it failed.
Did you manually changed the engine cert or some others CA cert?

Ok.

One note I did't specify, if it could influence my results.

I'm working on a laptop with Fedora 21.
The CentOS 7.1 hypervisor on which I'm working is a vm of this Fedora
system, where I enabled nested virtualization.

host-deploy on engine seems empty:

[root@shengine host-deploy]# pwd
/var/log/ovirt-engine/host-deploy
[root@shengine host-deploy]# ll
total 0
[root@shengine host-deploy]#

engine.log.gz of engine found here:
https://drive.google.com/file/d/0BwoPbcrMv8mvU0tsbXhEeHc2TlE/view?usp=sharing


timestamp to check against is between 17:15 and 17:40 of yesterday

I couldn't agree more with you... ;-)

Anyway yesterday I had to poweroff my laptop and so my environment and
today I power on the hypervisor again.
The engine VM automatically starts inside it and I can access the web admin
portal, but the host of course results as down.
Datacenters and Clusters are not populated; I only have the "Default".
See screenshot of portal with yesterday and today events for the host here:
https://drive.google.com/file/d/0BwoPbcrMv8mvZWJwdUhEXzJ3Wjg/view?usp=sharing

BTW: I find from the events that actually yesterday host-deploy log file is
on the host itself under /tmp
--> perhaps a better place on host?

Anyway here it is the generated file
ovirt-host-deploy-20151021172025-gbtn0q.log:

OK, thanks for the report.
Could you please attach HA agent logs from the host where the engine VM is
running?

I suspect that that host-deploy fails cause you have in place a leftover
VDSM cert from the previous attempt which is still signed by your previous
attempt engine and so it fails to match this new engine: on the second
attempt hosted-engine-setup deployed again the engine appliance creating a
new instance with different certs.

You could try to run on the host:

indeed, I made a subnet error.
I 've now changed the ip address of the host, that took me some searching.
Now I'm working on re-doing the nfs setup.
