[ovirt-users] NFS ISO Domain - Outage ?

2020-03-11 Thread 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

Thanks, Didi!  I'll go ahead and setup the NFS ISO domain in a separate cluster.

NFS ISO domain on the engine machine is generally deprecated, and
specifically problematic for hosted-engine, see also:

https://bugzilla.redhat.com/show_bug.cgi?id=1332813

I recently pushed a patch to remove the question about it altogether:

[ovirt-users] NFS ISO domain from hosted-engine VM

2017-03-23 Thread Devin A. Bougie
Hi, All.  Are there any recommendations or best practices WRT whether or not to 
host an NFS ISO domain from the hosted-engine VM (running the oVirt Engine 
Appliance)?  We have a hosted-engine 4.1.1 cluster up and running, and now just 
have to decide where to serve the NFS ISO domain from.

Many thanks,
Devin

Not completely on-topic, but somewhat related:
I just merged a couple of patches by Mark Wu (thanks Mark!) that remove the NFS 
limitation for ISO domains, and allow creating them on any file-based domain.
Perhaps we'd like to allow the installer to create the ISO domain on local 
storage?

that's only relevant for the AIO mode, not for any other mode?

It's a new ability, regardless of AIO.
I'm suggesting that AIO could utilize it, since it will remove the dependency
