The best HCI config with 8Nodes and 2 sites?
by Arman Khalatyan 23 Mar '21

23 Mar '21

Hello everybody, I would like to deploy HCI with our 2 buildings each with 8 compute nodes. Each host has a mirrored OS disks and 1 slot for the SSD. So I will use SSD for the glusterfs. my question is what is the best type of the glusterfs volume? I can leave with 8way mirror but what happened if the connection between buildings will go down? where will my ovirt-engine start?

user portal
by Enrico Becchetti 23 Mar '21

23 Mar '21

Dear all, I'm using ovirt 4.3.2 with its engine on a virtual machine. The nodes are all Centos 7.7. Both engine and hypervisor systems work on a 10.0.0.0 private network. Now I would like to let users access the ovirt web page (user portal) and for this I must necessarily add a second network interface to the engine by inserting a public ip. I can't use NAT. Can you give me any advice for this operation ? Can I add the network interface and then run engine-setup ? Will oVirt be accessible from both ip addresses at the end of this operation ? Lots of thanks.

What do some of the terms mean in the documentation?
by jenia.ivlev＠gmail.com 23 Mar '21

23 Mar '21

Hello I want to install oVirt virtualization software on my ArchLinux as a lab for learning and experimenting. I'm having trouble going through the documentation because I don't understand how the different pieces fit together. Specifically, what are the roles of the oVirt Node, oVirt Host and oVirt Engine? Thanks

No option to remove OpenStack Glance storage domain.
by Gary Taylor 22 Mar '21

22 Mar '21

Hi, I was playing around a few months ago and added an ovirt-image-repository storage domain. There wasn't a real purpose for doing it, just trying to learn and play around. I tried to remove it earlier but couldn't figure out how because the Remove button is greyed out. I got busy and forgot about it. I am trying to clean it up now but the Remove button is still greyed out for that domain. How do I get rid of it now? It isn't being used. It's unattached. I'm the admin. https://imgur.com/KBKUu16.png oVirt Open Virtualization Manager Software Version:4.4.4.7-1.el8 Thank-you, Gary

Re: oVirt process that writes to Gluster mount
by Ben 22 Mar '21

Well, I'll be -- you're absolutely right, and I'm a bit embarrassed I didn't consider that before. The node that's not healing shows connections from 2 FUSE clients, which I expect, and 3 glustershd, which I also expect. [root@gluster1 ~]# gluster volume status ssd-san client-list Client connections for volume ssd-san Name count ----- ------ glustershd 3 fuse 2 total clients for volume ssd-san : 5 ----------------------------------------------------------------- But the secondary node, which is constantly healing, *shows that it's missing a FUSE connection*: [root@gluster2 ~]# gluster volume status ssd-san client-list Client connections for volume ssd-san Name count ----- ------ glustershd 3 fuse 1 total clients for volume ssd-san : 4 ----------------------------------------------------------------- I had to restart the glusterd service on node 2 twice before the FUSE client reconnected and stayed connected. Thanks a ton, I really appreciate your help!

oVirt process that writes to Gluster mount
by Ben 22 Mar '21

22 Mar '21

Hi, I could use some help with a problem I'm having with the Gluster storage servers I use in my oVirt data center. I first noticed the problem when files would constantly heal after rebooting one of the Gluster nodes -- in the replica 2/arbiter, the node that remained online and the arbiter would begin healing files and never finish. I raised the issue with the helpful folks over at Gluster: https://github.com/gluster/glusterfs/issues/2226 The short version is this: after running a tcpdump and noticing malformed RPC calls to Gluster from one of my oVirt nodes, they're looking for a stack trace of whatever process is running I/O on the Gluster cluster from oVirt in order to figure out what it's doing and if the write problems could cause the indefinite healing I'm seeing. After checking the qemu PIDs, it doesn't look like they are actually performing the writes -- is there a particular part of the oVirt stack I can look at to find the write operations to Gluster? I don't see anything else doing read/write on the VM image files on the Gluster mount, but I could be missing something. NB: I'm using a traditional Gluster setup with the FUSE client, not hyperconverged. Thanks in advance for any assistance.
