[Jayme]

I think you may be misinterpreting hci. Even though the hosts are used for
storage it’s still not technically local storage as the hosts are acting as
clients and are mounting the gluster storage.. so storage is still over
network.

You can get better gluster performance if you switch To libgfapi however
it’s not a default option and has some known issues. I also read in a it
report recently that redhat doesn’t plan to implement it because the
performance improvements aren’t great, although many ovirt users on this
group seem to have seen a performance boost after switching to libgfapi.

If io performance is your main concern I’m not sure if gluster is the
answer. There are likely some others on this group who have more real world
experience with various environments and could give you more comparisons.

[ovirt-users] Re: Hyperconverged setup questions

[Vrgotic, Marko]

Hi Strahil , Leo and Jayme,



This thread is getting more and more useful, great.



Atm, I have 15 nodes cluster with shared Storage from Netapp. The storage 
network is (NFS4.1) on 20GB LACP, separated from control.

Performance is generally great, except in several test cases when using "send 
next data after write confirm". This situation does not care about speed of 
network, kernel buffers or any other buffers, but only about storage server 
speed, and then we hit the speed issue.



The main reason why I am asking for HCI, is to get as close as possible to 
Local Storage speed with multiple hosts in same cluster.

The idea is to add HCI to current setup, as second cluster, utilizing CPU RAM 
and LocalStorage of joined nodes.

--Is this actually a direction which will get me to the wanted result, or am I 
misunderstanding purpose of HCI?



I understand that the HCI with SHE requires replica2+arbiter or replica3, but 
that is not my situation. I wish only to add HCI for reasons above.

--Do I need the distributed-replicated in that case, or I can simply use 
distributed (if still supported) setup?



Jayme, I do have resources to set this up in a staged environment, and I will 
be happy to share the info, but first I need to find out if I am at all moving 
in right direction.



Kindly awaiting your reply.

Hi Jayme,

As this is a distributed-replicated  (or maybe the term is the opposite  -  it 
doesn't matter) with shard option enabled - the VM disk will be spread on all 
bricks and I expect faster  reads and even a little bit faster  writes  (as  1  
shard can go to first replica set, while  another 1 can go to the second 
replica set).

The  problem you can hit is that if a whole replica  set (f

[Jayme]

I currently have a three host hci in rep 3 (no arbiter). 10gbe network and
ssds making up the bricks. I’ve wondered what the result of adding three
more nodes to expand hci would be. Is there an overall storage performance
increase when gluster is expanded like this?

[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

Hi Marko,

Jayme  has explained it all.
If you wish HCI - you should use 3  ->  6 -> 9 nodes  (in 'replica 2 arbiter 1' 
& 'replica 3' volumes ).
Of course  you can connect other hosts but they will not have gluster running 
on them.

Strahil Nikolov

Marko,

>From my understanding, you can have more than 3 hosts in a HCI cluster but
to expand HCI you need to add hosts in multiples of three.  I.e. go from 3
hosts to 6 or 9 etc.

You can still add hosts into the cluster as compute only hosts though.  So
you could have 3 hosts with gluster and a 4th that is just compute.

[ovirt-users] Re: Hyperconverged setup questions

[Vrgotic, Marko]

Hi Strahil,

I circled back on your reply while ago regarding oVirt Hyperconverged and more 
than 3 nodes in cluster:


“Hi Marko, I guess  you can use distributed-replicated volumes  and oVirt  
cluster with host triplets.”
Initially I understood that its limited to 3Nodes max per HC cluster, but now 
reading documentation further 
https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Maintenance_and_Upgrading_Resources.html
 that does not look like it.

Would you be so kind to give me an example or clarify what you meant by “you 
can use distributed-replicated volumes  and oVirt  cluster with host triplets.” 
?

Kindly awaiting your reply.

Hi Strahil,

Thank you.
One maybe stupid question, but significant to me:
Considering i haven’t been playing before with hyperconverged setup in oVirt, 
is this something i can do from ui cockpit or does it require me first setup an 
Glusterfs on the Hosts before doing anything via oVirt API or Web interface?

Kindly awaiting your reply.

Hi,
 Yes you can expand your cluster using cockpit in day2 operation.
You need to login to cockpit and then click "Manage Gluster" -> "Expand Cluster"

Hi Marko,

I'm not a big fan of GUI/UIs , so I cannot tell you.Most probably it is 
possible.
