Recommended setup for a FC based storage domain
by combuster＠archlinux.us 12 Jun '14

12 Jun '14

Hi, I have a 4 node cluster setup and my storage options right now are a FC based storage, one partition per node on a local drive (~200GB each) and a NFS based NAS device. I want to setup export and ISO domain on the NAS and there are no issues or questions regarding those two. I wasn't aware of any other options at the time for utilizing a local storage (since this is a shared based datacenter) so I exported a directory from each partition via NFS and it works. But I am little in the dark with the following: 1. Are there any advantages for switching from NFS based local storage to a Gluster based domain with blocks for each partition. I guess it can be only performance wise but maybe I'm wrong. If there are advantages, are there any tips regarding xfs mount options etc ? 2. I've created a volume on the FC based storage and exported it to all of the nodes in the cluster on the storage itself. I've configured multipathing correctly and added an alias for the wwid of the LUN so I can distinct this one and any other future volumes more easily. At first I created a partition on it but since oVirt saw only the whole LUN as raw device I erased it before adding it as the FC master storage domain. I've imported a few VM's and point them to the FC storage domain. This setup works, but: - All of the nodes see a device with the alias for the wwid of the volume, but only the node wich is currently the SPM for the cluster can see logical volumes inside. Also when I setup the high availability for VM's residing on the FC storage and select to start on any node on the cluster, they always start on the SPM. Can multiple nodes run different VM's on the same FC storage at the same time (logical thing would be that they can, but I wanted to be sure first). I am not familiar with the logic oVirt utilizes that locks the vm's logical volume to prevent corruption. - Fdisk shows that logical volumes on the LUN of the FC volume are missaligned (partition doesn't end on cylindar boundary), so I wonder if this is becuase I imported the VM's with disks that were created on local storage before and that any _new_ VM's with disks on the fc storage would be propperly aligned. This is a new setup with oVirt 3.4 (did an export of all the VM's on 3.3 and after a fresh installation of the 3.4 imported them back again). I have room to experiment a little with 2 of the 4 nodes because currently they are free from running any VM's, but I have limited room for anything else that would cause an unplanned downtime for four virtual machines running on the other two nodes on the cluster (currently highly available and their drives are on the FC storage domain). All in all I have 12 VM's running and I'm asking on the list for advice and guidance before I make any changes. Just trying to find as much info regarding all of this as possible before acting upon. Thank you in advance, Ivan

Posting to ovirt-devel will help in having people to review your patches. I did "git blame" on the file you changed in http://gerrit.ovirt.org/28113 and added those who already changed that file for reviewing the patch. > Who decides which oVirt version will include this code or if this code will be included or needs adaptions (I only know that a certain score in gerrit > is required and some developers are allowed to rate a commit)? > > I'm aware that my commit isn't fancy at all and there's no need for any priority, but just want to know what's the right workflow in case I have more > time to work on some bugs... > > I guess these questions could be interesting for users (basically for users who are not familiar with a professional development setup/workflow > including gerrit like me) who want to work on the bugs in june edition as well... I agree. You did everything right since now: - opened a bz - pushed a patch referencing it - added the gerrit reference to bugzilla what you just miss is adding other people for reviewing the patch. Oved Ourfali already set whiteboard to virt, so this is a virt team patch and virt team maintainers will merge your patch once it's ready. Itamar Heim also reviewd the bug you pushed and set target release to 3.5.0. Now you just need to wait for other developers to review the patch and maintainer to merge it. If there will be comments on your patch a new version of the patch may be needed (just amend the patch and push again with the same Change-ID) and it will be reviewed again. you can find more info on gerrit here: https://gerrit-review.googlesource.com/Documentation > > > Thanks, > René > > > On 06/12/2014 04:11 PM, Sandro Bonazzola wrote: >> Hi, >> have you got some free time and do you want to get involved in oVirt integration? >> After the success of first edition we're now proposing this again. >> Here are a couple of bugs you can hopefully fix in less that one day or you can just try to reproduce providing info: >> >> Bug 1091651 - Misleading error message when first host cannot be reached during hosted-engine deployment >> Bug 1080823 - [RFE] make override of iptables configurable when using hosted-engine >> Bug 1065350 - hosted-engine should prompt a question at the user when the host was already a host in the engine >> Bug 1097635 - ovirt-hosted-engine-setup fails with Modules libvirt contains invalid configuration >> >> Is this the first time you try to contribute to oVirt project? >> You can start from here [1][2]! >> >> [1] http://www.ovirt.org/Develop >> [2] http://www.ovirt.org/Working_with_oVirt_Gerrit >> >> -- Sandro Bonazzola Better technology.

Re: [ovirt-users] Users seeing all vm's
by Jeff Clay 12 Jun '14

Yes, I have resolved this issue. It was due to my lack of understanding in how Ovirt expected things to be configured and setup. Are you using active directory for authentication and setting up pools of vm's for users to access?

help, manager hard drive died (3.3.4)
by David Smith 12 Jun '14

12 Jun '14

So the ovirt manager hard disk died, 3.3.4 version, i can't get it to spin up to get any data off. I have an old copy of the manager database which was living on the manager machine. What is the best procedure for restoring my ovirt setup? I've not been able to import the data store, only export and iso in the past. Thanks in advance, David

ISO
by Moritz Mlynarek 11 Jun '14

11 Jun '14

Hello, after installing ovirt 3.4 I tried to add an ISO File to my ovirt system. But there was no local-iso-share. The command "engine-iso-uploader list" told me "ERROR: There are no ISO storage domains". I tried to create a new domain (ISO / Local on Host) but I was not able to choose a HOST. Sorry for my poor english. :( Moritz Mlynarek
