Dear Team,
We are using Ovirt 4.0 for POC what we are doing I want to check with all
Guru's Ovirt.
We have 2 hp proliant dl 380 with 500GB SAS & 1TB *4 SAS Disk and 500GB SSD.
Waht we are done we have install ovirt hyp on these h/w and we have
physical server where we are running our manager for ovirt. For ovirt hyp
we are using only one 500GB of one HDD rest we have kept for ceph, so we
have 3 node as guest running on ovirt and for ceph. My question you all is
what I am doing is right or wrong.
Regards
Rajat

I think Ceph requires a lot more resources than above. It's also a bit more
challenging to configure. I would highly recommend a 3-node cluster with
Gluster.

Hi,
having a 3-node ceph cluster is the bare minimum you can have to make it wor=
king, unless you want to have just a replica-2 mode, which is not safe.
It's not true that ceph is not easy to configure, you might use very easily c=
eph-deploy, have puppet configuring it or even run it in containers. Using d=
ocker is in fact the easiest solution, it really requires 10 minutes to make=
a cluster up. I've tried it both with jewel (official containers) and krake=
n (custom containers), and it works pretty well.
The real problem is not creating and configuring a ceph cluster, but using i=
t from ovirt, as it requires cinder, i.e. a minimal setup of openstack. We h=
ave it and it's working pretty well, but it requires some work. For your ref=
erence we have cinder running on an ovirt VM using gluster.
Cheers,

Great, thanks! Alessandro ++ Yaniv ++
What I want to use around 4 TB of SAS disk for my Ovirt (which going to be
RHV4.0.5 once POC get 100% successful, in fact all product will be RH )
I had done so much duckduckgo for all these solution and use lot of
reference from ovirt.org & access.redhat.com for setting up a Ovirt engine
and hyp.
We dont mind having more guest running and creating ceph block storage and
which will be presented to ovirt as storage. Gluster is not is use right
now bcoz we have DB will be running on guest.

Hi Rajat,
sorry but I do not really have a clear picture of your actual setup, can you=
please explain a bit more?
In particular:
1) what to you mean by using 4TB for ovirt? In which machines and how do you=
make it available to ovirt?
2) how do you plan to use ceph with ovirt?
I guess we can give more help if you clarify those points.
Thanks,
Alessandro=20

Hi Alessandro,
Right now I have 2 physical server where I have host ovirt these are HP
proliant dl 380 each server 1*500GB SAS & 1TB *4 SAS Disk and 1*500GB SSD.
So right now I have use only one disk which 500GB of SAS for my ovirt to
run on both server. rest are not in use. At present I am using NFS which
coming from mapper to ovirt as storage, go forward we like to use all these
disk as hyper-converged for ovirt. RH I could see there is KB for using
gluster. But we are looking for Ceph bcoz best pref romance and scale.

Hi Rajat,
sorry but I do not really have a clear picture of your actual setup, can
you please explain a bit more?
In particular:
1) what to you mean by using 4TB for ovirt? In which machines and how do
you make it available to ovirt?
2) how do you plan to use ceph with ovirt?
I guess we can give more help if you clarify those points.
Thanks,
Alessandro

What I want to use around 4 TB of SAS disk for my Ovirt (which going to be
RHV4.0.5 once POC get 100% successful, in fact all product will be RH )
I had done so much duckduckgo for all these solution and use lot of
reference from ovirt.org & access.redhat.com for setting up a Ovirt
engine and hyp.
We dont mind having more guest running and creating ceph block storage and
which will be presented to ovirt as storage. Gluster is not is use right
now bcoz we have DB will be running on guest.

Hi,
oh, so you have only 2 physical servers? I've understood they were 3! Well, i=
n this case ceph would not work very well, too few resources and redundancy.=
You could try a replica 2, but it's not safe. Having a replica 3 could be f=
orced, but you would end up with a server with 2 replicas, which is dangerou=
s/useless.
Okay, so you use nfs as storage domain, but in your setup the HA is not guar=
anteed: if a physical machine goes down and it's the one where the storage d=
omain resides you are lost. Why not using gluster instead of nfs for the ovi=
rt disks? You can still reserve a small gluster space for the non-ceph machi=
nes (for example a cinder VM) and ceph for the rest. Where do you have your c=
inder running?
Cheers,
Alessandro

Alessandro,
Right now I dont have cinder running in my setup in case if ceph don't work
then I have get one vm running open stack all in one and have all these
disk connect my open stack using cinder I can present storage to my ovirt.
At the same time I not getting case study for the same.

Hi,
oh, so you have only 2 physical servers? I've understood they were 3!
Well, in this case ceph would not work very well, too few resources and
redundancy. You could try a replica 2, but it's not safe. Having a replica
3 could be forced, but you would end up with a server with 2 replicas,
which is dangerous/useless.
Okay, so you use nfs as storage domain, but in your setup the HA is not
guaranteed: if a physical machine goes down and it's the one where the
storage domain resides you are lost. Why not using gluster instead of nfs
for the ovirt disks? You can still reserve a small gluster space for the
non-ceph machines (for example a cinder VM) and ceph for the rest. Where do
you have your cinder running?

Alessandro

coming from mapper to ovirt as storage, go forward we like to use all these

gluster. But we are looking for Ceph bcoz best pref romance and scale.

Hi Rajat,
OK, I see. Well, so just consider that ceph will not work at best in your se=
tup, unless you add at least a physical machine. Same is true for ovirt if y=
ou are only using native NFS, as you loose a real HA.
Having said this, of course you choose what's best for your site or affordab=
le, but your setup looks quite fragile to me. Happy to help more if you need=
.

Alessandro

Hi Rajat,
3 is the bare minimum, but yes, it works well, as I said before. But you sti=
ll have to decide weather you want to have more resiliency for ovirt, and st=
andard NFS is not helping much.
If you plan to run your cinder or openstack all in one box as VM in ovirt as=
well you should consider moving from standard NFS to something else, like g=
luster.
Cheers,
Alessandro

It's not true that ceph is not easy to configure, you might use
very
easily ceph-deploy, have puppet configuring it or even run it in
containers. Using docker is in fact the easiest solution, it really
requires 10 minutes to make a cluster up. I've tried it both with jewel
(official containers) and kraken (custom containers), and it works pretty
well.
This could be a great blog post in ovirt.org site - care to write something
describing the configuration and setup?
Y.
The real problem is not creating and configuring a ceph cluster, but
using
it from ovirt, as it requires cinder, i.e. a minimal setup of openstack. We
have it and it's working pretty well, but it requires some work. For your
reference we have cinder running on an ovirt VM using gluster.
Cheers,
Alessandro

I think Ceph requires a lot more resources than above. It's also a bit
more challenging to configure. I would highly recommend a 3-node cluster
with Gluster.

Yaniv,
If I am not wrong your referencing to this
https://www.ovirt.org/develop/release-management/features/cinderglance-do...
But only issue here right now this is not add from RH officially, after
finish this we will going for RH product.

One if the ceph clusters we use had exactly this setup: 3 DELL R630 (ceph je=

dedicated interface, 1Gbps. I can say it works pretty well, the performance=
reaches up to 100MB/s per rbd device, which is the expected maximum for the=
network connection. Resiliency is also pretty good, we can loose 2 osds (I.=
e. a full machine) without impacting on the performance.
