I noticed Gluster 4k support mentioned in recent oVirt release notes. Can
anyone explain what this is about?

[ovirt-users] Re: NFS ISO Domain - Outage ?

[eevans]

I have notice in testing that if the ISO domain goes down, it does affect the 
vm's. The same server also has the sdm export domain on it, which I think 
houses most of the hard disks. Once the host came back up, everything resumed 
normal operations.

Hi Nardus,

The iso domain is deprecated, but there  are some issues  when uploading ISOs 
to block-based data domains.Using  ISOs uploaded  to gluster-based  data domain 
is working pretty fine (I'm using it in my LAB),  but you need to properly test 
prior implementing on Prod.

As far as I know, oVirt is making I/O checks frequently , so even the hard 
mount option won't help.

Is your NFS  clusterized ? If not ,you may consider clusterizing it.

Actually, did your VMs got  paused  or completely crashed ?

Strahil Nikolov

In such case , you can consider  clusterization of the NFS Server if it is 
Linux-based one.

Hi

Thanks for the response. Seems that they got paused, all came right after
the NFS server came backup.

[ovirt-users] ETL Service

[Anton Louw]

Hi All,

I am having a strange issue. I configured my DWH scale with scales that I would 
like to report on. I checked this morning, and the last row in my PostgreSQL DB 
is from the 9th. I checked the logs, and I see that it is referring to an "ETL 
Service" which I am not familiar with. I have attached the lines in the text 
document.

If anybody could point me in the right direction, it would be greatly 
appreciated.

Thank you

[ovirt-users] NFS ISO Domain - Outage ?

[Nardus Geldenhuys]

Hi Ovirt Mailing-list

Hope you are well. We had an outage over several ovirt clusters. It looks
like we had the same ISO NFS domain shared to all off them, many of the
VM's had a CD attached to it. The NFS server went down for an hour, all
hell broke lose when the NFS server went down. Some of the ovirt nodes
became "red/unresponssive" on the ovirt dashboard. We learned now to spilt
the NFS server for ISO's and/or remove the ISO's when done.

Has anyone seen similar issues with an NFS ISO Domain? Is there special
options we need to pass to the mount to get around this? Can we put the
ISO's somewhere else?

Regards

Nardus
