So when I run a copy operation it is successful. Move and export do not

Can you please file a bug with all details, such as logs and version used?
Thanks,

[ovirt-users] Basic parts for rebuilding ovirt server

[Alex Bartonek]

Kinda pleased with the way the restore went. Sucks that my backups weren't 
working like I thought.

I did an engine backup, complete about a day before I lost data.

Are these the basic steps:

1. Reinstall CentOS (whatever OS you used)
2. Update all packages
3. Install ovirt
4. Engine restore
5. Engine setup

That gets you a basic ovirt server with your previous settings.

My problem:
Storage domains are gone along with the vms. How do I remove the VM's and 
storage domains that way I can recreate them?

Thanks

Re: [ovirt-users] Bad hd? or?

[Alex Bartonek]

Looks like the HD went bad.  I was able to restore from backups which were...20 
days old.  :-/  Nice.   Looks like my backup process hd issues and I never 
realized it.

Got it all sorted out.

Re: [ovirt-users] Has meltdown impacted glusterFS performance?

Where are you getting these numbers from?
We've seen much lower numbers.

It is processor dependent, so newer are less affected as older CPUs.
Also, keep in mimd that additional patches are expected that will bring
back some of the performance.
