Deleting master storage
by jin&hitman&Barracuda 25 Jul '18

25 Jul '18

Hi, Trying to build an ovirt system and i'm stuck with storage problem. I've prepared iscsi storage and seems like my storage had some troubles and now i could not get it online again. That is another story. I just want to delete master storage domain on ovirt manager. Looks like this is not allowed since there is no storage domain candidate to take master role. Also i could not add another storage domain becouse that is not allowed too. It says "can not add because there is no active storage domain" or something similar. Basically i'm stuck and don't know how to delete storage domain (master) without tear down all of them.

Backup Strategies
by Markus Schaufler 25 Jul '18

25 Jul '18

Hi! We use in our test infrastructure a NetApp shared fc storage and wonder how a backup strategie could look like. Full backups aren't the problem - trigger HV Snapshots including guest FS freeze / quiece, trigger NetApp Snapshot, delete HV Snapshots. Currently I'm struggeling on how to recover those Backups. I would provide the Snapshot volume to the hosts and import it as a new data domain, so the hosts have the snapshot disks as logical volumes. But how could I recover respectively move the content of the snapshot volumes onto the currently used vm "disk volumes"? If I have the proof of concept then scripting it to make this process more comfortable wouldn't be a problem. How do you do your backups with shared san? How can I provide incremental Backups? Thanks for any help!

Xen Free Edition migration to oVirt
by Sandro Bonazzola 24 Jul '18

24 Jul '18

Hi, If you were using Xen Free Edition or if you are still using it, after https://xenserver.org/blog/entry/xenserver-7-3-changes-to-the-free-edition.… you may be looking at oVirt as alternative. A community tool to ease the migration exist here: https://github.com/zipurman/oVIRT_Simple_Backup. Did you migrate to oVirt or are you planning it? I was wondering if it may help organizing an hackathon day for helping users doing the migration would make sense, so I'd like to know if there are users looking for assistance in the migration process. Let us know! -- SANDRO BONAZZOLA MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://red.ht/sig>

How to keep VM running when a storage domain is offline
by Matthew B 24 Jul '18

24 Jul '18

Hello, I am trying to understand how I can prevent a VM from being paused when one of it's disks is unavailable due to a problem with the storage domain. The scenario: A VM with 3 disks. OS disk on a highly available domain. And Two large disks each on separate domains. (so a total of 3 domains). The two large disks are mirrored using ZFS - but when one of the storage domains goes down the VM pauses. Is is possible to configure the VM to not pause when certain storage domains are unavailable? So instead of getting Paused due to IO error the disk would just be missing until that domain was brought back online? Thanks, -Matthew

Error when change CD
by markus.schaufler＠ooe.gv.at 24 Jul '18

24 Jul '18

Hi! I created an NFS ISO Domain but couldn't find any upload button. Because uploading ISO files on the Data Domain I went that comfortable way. I successfully started Installation of Windows Server 2016 until the virtio Drivers for the disk are needed. So I tried to Change CD but following error occured: "Error while executing Action Change CD: Drive Image file could not be found" Changing CD works when using another ISO file like Centos. The iso itself is good - I can read it on my own System - but anyhow I tried another download of the virtio-win-iso - with the same result. I already found several threads around this Topic - e.g. "do not upload ISO files to data Domain" So I'd like to know how the upload to the ISO Domain is supposed to work if there's no "upload" button? Directly via SCP into the subfolders? Did I miss some configuration or is the workflow in uploading ISO's respectively in installing a Windows VM wrong? Thanks for any help!
