[ovirt-users] Hyperconverged setup ovirt 4.3.x using ansible?
Hi, I am trying to do a Hyperconverged setup using ansible. So far I have been able to run a playbook to setup gluster but have not been able to identify how to install the Hosted-Engine VM using ansible and tie all the pieces together. Can someone point me in the right direction to deploy a hyperconverged environment using ansible? I have succesfully deployed ovirt 4.3.5 (Hyperconverged) using the web UI. thanks. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/5MHEOITDNKEYPUPN2AI2J4GRAK3LZSKI/

[ovirt-users] Hosted Engine on seperate L2 network from nodes?
For some security requirements, I’ve been asked if it’s possible to segregate the hosted engine from the physical nodes, with specific firewalling for access to do node/ storage operations (I’m using managed block storage). Is this an approach others us, or is it better practice and just ensure the nodes and engine are all sharing the same network? Thanks, dan The Networking People (TNP) Limited.

[ovirt-users] Adding VLANs to a single-host, self-hosted-engine oVirt deployment?
HI, I've got a single oVirt host running a self-contained hosted-engine deployment. When I set it up I did not use VLANs in my network. I am in the process of moving my equipment, and in part of this move I would like to introduce VLANs into my network infrastructure. The documentation seems to imply that to add virtual networks and/or VLANs to a host that I need to put it into maintenance mode, configure it in the engine, and then resync the network. However, I don't think I can do that with a single-host environment. If I put the host into local maint mode, it will try to offload all my VMs, including the engine, which obviously it cannot do because there is no other host to migrate them to. So what's the approach to add VLANs in this situation? I should add that this system started at 4.0, and I'm still only running 4.1 (although I do plan to upgrade to 4.2 as part of this move). I'm hesitant to upgrade further because of the impending removal of SDK-3 -- I am depending on a script that uses ovirt-shell which I keep being told is going away. If ovirt-shell is still in 4.3 then I might consider upgrading to that as well. :) Thanks. -derek -- Derek Atkins 617-623-3745 de...@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/3KR6PJE2XHNISXCJXG3GNADXEHWHWEXI/
[ovirt-users] Hyperconverged on a self-made Gluster: Considered normal or 'way-off'?
I use three very low power target nodes (J5005 Intel Atoms, 24GB RAM, 250GB SSD) to experiment with hyperconverged oVirt, and some bigger machines to act as pure compute nodes, preferably CentOS based, potentially oVirt Node image based. I've used both CentOS7 and oVirt Node image bases (all latest versions and patches) and typically I use either a single partition and xfs root file system to avoid partitioning the constricted space on CentOS or the recommended partition layout with the oVirt node images, which still consumes the single primary SSD /dev/sda. In both cases I don't have another device or partition left for the three-node hyperconverged wizard's ansible scripts to play with. And since I want to understand better what is going on under the hood in any case I tried to separate the Gluster setup and the hosted-engine setup. Question: Is the impact of that decision perhaps far bigger than I imagined? So I went with the alternative A Hosted-Engine wizard, where the storage was already provisioned and I had set up 2+1 Gluster storage using bricks right on the xfs, assuming I would achieve something very similar to what the three node wizard would simplify, except without the LVM/VDO layer all done with Ansible. But I am running into all kinds of problems and what continues to irritate me is the note in the manuals, that clusters need to be either 'compute' or 'storage' but cannot be both--yet that's the very point of hyperconvergence... So basically I am wondering whether at this point there is a strict bifurifcation of oVirt between the hyperconverged variant and the 'Hosted-Engine' on existing storage, without any middle ground. Or is it ok to do a two-phased approach, where you separate out the Gluster aspect and the Hosted-Engine *but with physical servers that are doing both storage and compute*? Also, I am wondering about the 'Enable Virt Service' and 'Enable Gluster Service' tick boxes in the Cluster property pages: For my 'hosted engine' wizard generated Cluster 'gluster' was unticked, even if it did run on Gluster storage. And while ticking 'gluster' in addition had no visible effect, unticking either one of the two is now impossible. I could not find any documentation on the significance or effect of these boxes. While the prepared three node replicated storage Gluster for the /engine was running on CentOS nodes, the Hosted-Engine VM was then created on additional oVirt Node hosts using that Gluster storage (trying to do the same on CentOS nodes always fails, separate topic), with the assumption that I could then push the hosted-engine VM back to the gluster storage nodes and get rid of the temporary compute-only host used for hosted engine setup. I then tried to add the Gluster nodes as hosts (and hosted-engine backup nodes), that also failed. Whether it failed because they were CentOS based or because they were already used for storage (and there is this hidden exclusivity), I would like to have some clarity on. So to repeat once again my main question: Is the (one or three) node hyperconverged oVirt setup a completely different thing from the hosted-engine on Gluster? Are you supposed to be able to add extra compute hosts, storage etc. to be managed by a three-node HC based hosted-engine? Are you supposed to be able to expand the three-node HC also in terms of storage, if perhaps currently only in quorum-maintaining multiples? Is oVirt currently actually strictly mandating 100% segregation between compute and storage unless you use the wholly contained single/triple HC setups? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/X3UBQT3ZKAX64TWKZQSBJ2ZUCPYNOXH7/
[ovirt-users] Re: Disk Allocation policy changes after a snapshot
Hi I agree with everyone about using preallocated disks for DB and that is the setup I have, the issue I am raising is that when you create a snapshot of a preallocated disk it changes to a sparse disk, because of this change in policy the VM crashes under heavy writes. I modified vdsm.conf and added [irs] volume_utilization_percent = 25 volume_utilization_chunk_mb = 2048 This has cured the VM crashing under intense writes after I have created a snapshot.
