@obsolesce said in Fedora 28 Server - Linux 101 - How do you partition your drives:
This has already saved me a few times, when having to reload or restore the OS while keeping the
/dataor/homepartitions intact. All cases were when using LVM.
I've had to do this a few times & re-installing the o/s on the separate partition made it super easy!
@matteo-nunziati Yes, thanks for the link.
It is stored in org/virt-manager/virt-manager/conns

@francesco-provino This is a 3 + 1 node hyperconverged cluster with Gluster, HA, Live Migration etc!
That's what I was wondering. I didn't know if it was a self hosted engine (couldn't think of the name last night) or multiple node setup.
This setup uses the Hosted Engine.
oVirt Node v4.3 (based on Fedora 28) - this is pre-release:

Can we use the oVirt system to manage an existing KVM server?
( I want to try oVirt, but really don't want to wipe out the system I currently have set up )
Unfortunately not.
@emad-r said in Testing oVirt...:
Let us talk about Gluster, how do you feel safe with it ?
saw you choose an option with RAID 6, i dont get that cause from my trial, I make RAID and group disks then create Gluster volume from those mdraid volume, but it seems you did RAID 6 afterwards, hmm whats the logic behind that ?
What type of Gluster volume are you using, just distributed ?
I m still learning HCI so thus the beginner vibe
No RAID6, I'm using RAID10.
Gluster volume is Replicate + Arbiter
This is a good blog post to get you started: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster-storage/

( I want to try oVirt, but really don't want to wipe out the system I currently have set up )I tried setting up oVirt a few versions ago and from what I could find, it's almost expected you have a minimum of 3 physical hosts for it.
So no, you won't be able to manage a standalone KVM server since everything has to get built to be managed by the oVirt Engine.
You can now do a single host w Gluster:

Here's a screenshot of my single node install:

@travisdh1 said in NFS Server...what to build??:
Well, first of all I wouldn't do a split array. OBR (One Big RAID), unless you have a very specific reason to do otherwise.
Easy to do with my SM box, since it has 2x 2.5" sleds on the backside running off the onboard SATA.
Virtualize, all the time and all the things.
Yes agreed!
Fedora, probably on top of XCP-NG. Assuming you don't have a Scale cluster to use at least.
You are one of those in the XCP camp! I tend to prefer Fedora 28.
Of course, I'd lean to using NextCloud for file storage anymore for most file storage, so probably wouldn't be deploying new NFS server in most cases.
No NextCloud, this is for storing backups of vm's.

@fateknollogee said in NFS Server...what to build??:
So you want to build an NFS Server to "share" files with other clients.
What o/s would you base this build on...?
Install o/s on bare metal or virtualize?HW is simple:
- 2x SSD for o/s
- 4 - xx SSD for NFS shares
I set one up on Fedora Server to act as a storage repository for ReaR backups. I did it on a VM.
Where is that blog post or it didn't happen? ..jk
@Emad-R No good reason to pay the premium for nVMe drives just for installing the o/s.
I use Intel S35xx/S36xx - 120GB.
Plenty available on ebay at $50 each!
@romo said in Testing oVirt...:
@fateknollogee Free for standalone KVM hosts, this seems interesting. Please share your testing results =).
I'll update you tomorrow after I test some restores.
I've backed up a few vm's to AWS S3 & to on-prem servers.
I remember this has been discussed on the forums sometime back when...
I'd like to have a master host file & push this out to Linux & Windows servers & desktops.
Anyone have a good how to guide?
@hobbit666 said in Testing oVirt...:
So would you only use it in a "cluster" of servers?
You can do a single node or 3 nodes. (nodes aka hosts)
Those are your typical setups.
oVirt single node gluster install
In the next release (which will 4.2.7), you'll be able to deploy a single node install from Cockpit UI.

@scottalanmiller said in Fedora 29 Workstation...thinkin' ahead:
@fateknollogee how is the third party library? Like what if I have an RPM to add to it, and there is no DNF?
After, I saw your post, I literally just fired it up (as a vm).
Let me try to add some RPM's & a few snaps.
I'll be right back.

I haven't had a chance to use Silverblue yet, but on atomic (renamed to Silverblue) you could install RPMs but they were installed on an overlay filesystem. Pretty much everything on here is flatpak/snap or Docker.
It's actually pretty cool. It uses ostree for updates. I watched a guy rebase his OS from Fedora to CentOS and back and nothing changed from the user perspective. Pretty interesting.
I have to agree, just quickly scanning the docs, I like what I'm seeing.
So far for me, no regrets using fc 26/27/28 as my daily machine after many years on Win 7/8/8.1/10.
