Iirc you need to have multiples of three severs for hyperconverged. You
could have a 4 server cluster but only three of them would be participating
in storage and one would be compute only. Someone correct me if I’m wrong.

Your nodes should have separate drives for node image. The installer will

Most of your node specific questions I think can be cleared up if you think
of the storage as being networked storage. Even though
The same as you would network a bare metal server.
If you want to access a web server from anywhere you need a public ip. The
vm itself doesn’t necessary have to have the public ip bound you could do
nat with an internal up address then have a public ip forwarded to it.

I’ve done this before by attaching an nfs storage domain, exporting the vm
to it the. Detaching and reattaching to the other cluster and importing.
There are probably more efficient ways to go about it.

Are there currently any known issues with using libgfapi in the latest

Good backup products for ovirt seem hard to come by. If you want to backup

The biggest problem with these tools is that they are very inefficient. To
work they snapshot the VM then clone the snapshot into a new VM, back it up
then delete. This takes a lot of space and time.

I suppose it would matter how that disk is presented and used by the

If it’s just a data disk maybe not.

Yes you should install node on separate boot drives and add your additional
drives for gluster. You do not have to do anything with gluster beforehand.
The ovirt installer will prepare the drives and do all the needed gluster

Ansible can be daunting simply because of how powerful it is, but it’s
actually quite easy to run a simple playbook like the one I’m writing for

ansible and all the needed dependencies installed.
I’m working on throwing together

This is all that should be needed, I've done so on my engine and it works
fine to set the timeout much higher. My guess is that you did not restart
the engine after changing the config.

What if any steps do I need to take prior to adding an additional gluster
volume to my HCI cluster using new storage devices via the oVirt gui? Will
the gui prepare the devices (xfs/lvm etc) or do I need to do that prior?

At the very least you should make sure to apply the gluster virt profile to
vm volumes. This can also be done using optimize for virt store in the
ovirt GUI

I too struggle with speed issues in hci. Latency is a big problem with
writes for me especially when dealing with small file workloads. How are
you testing exactly?
Look into enabling libgfapi and try some comparisons with that. People have
been saying it’s much faster, but it’s not a default opti
Hey Sandro,
Do you have more specific details or guidelines in regards to the graphics
you are looking for?
Thanks!

I strongly believe that FUSE mount is the real reason for poor performance
in HCI and these minor gluster and other tweaks won't satisfy most seeking
i/o performance. Enabling libgfapi is probably the best option. Redhat has
recently closed bug reports related to libgfapi citing won't fix and one

Christian,
I've been following along with interest, as I've also been trying
everything I can to improve gluster performance in my HCI cluster. My issue
is mostly latency related and my workloads are typically small file
operations which have been especially challenging.
Couple of things

Was wondering if there are any guides or if anyone could share their
storage configuration details for NFS. If using LVM is it safe to snapshot
volumes with running VM images for backup purposes?

In oVirt admin go to Storage > Domains. Click your storage domain. Click
"Virtual Machines" tab. You should see a list of VMs on that storage
domain. Click one or highlight multiple then click import.

What is the vm optimizer you speak of?
Have you tried the high performance vm profile? When set it will prompt you
to make additional manual changes such as configuring numa and hugepages
etc

You should be using a different subnet for each. I.e. 10.0.0.30 and
10.0.1.30 for example
