[Users] ISO datastore, permission denied

I have an ISO datastore. In that datastore I'm using symlinks to point
to my ISOs on an NFS share. All was working great.
Along comes Black Friday and a shiny new 3TB hard drive. Out goes the 5
yo old 500gb drive with EXT 4 and in comes new 3TB drive with BTRFS.
I installed new drive, shutdown VMs and use tar c | tar x to move data
over. unmount old, remount new. Fire up VMs, all us well. Create new
VM, attach boot ISO and I get:

These messages might have something to do with reading
information/statistics through the API.
But I've stopped all my (monitoring) processes using the API.
Restarting ovirt-engine and vdsm did not resolve the issue.
Both nodes and engine server are running oVirt 3.3.1 on CentOS 6.4
This may be a red herring but the values of disk statistics read
through the API are "static"/unchanging.
Any clues on whether these messages are serious and any ideas on how
to stop them
spamming my system logs?

[Users] Cannot configure storage
by Nauman Abbas
Hello all
I'm booting oVirt node from USB and want to use my hard drive for storing
VMs and stuff. When I have booted the node from USB I try to mount the hard
drive into a folder in the file-system but I am getting the following error.
mount: /dev/sda1 is already mounted or /mnt busy
Anyone who knows about this error?

[Users] REST Error during VM creation
by Sven Kieske
Hi,
when we try to create a vm via REST-API, we get the following error
via REST:
<h1>HTTP Status 500 - org.codehaus.jackson.map.JsonMappingException:
(was java.lang.NullPointerException) (through reference chain:
org.ovirt.engine.api.model.VM["console"])</h1><HR size="1"

<u>The server encountered an internal error
(org.codehaus.jackson.map.JsonMappingException: (was

org.ovirt.engine.api.model.VM["console"])) that prevented it
from fulfilling this request.</u></p><HR size="1"
noshade="noshade"><h3>JBoss Web/7.0.13.Final</h3>
However, the vm is correctly created (see attached engine.log).
This is ovirt-engine 3.3.2-1.el6
Any suggestions?
We need to be able to get the correct response via API.
Should I open a BZ for this?

[Users] iso domain in maintenance and VMs cannot start
by Ernest Beinrohr
This is a multi-part message in MIME format.
--------------090405020804010702020405
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit
It is obvious that when an VM has a iso attached
and the iso domain is in maintenance the VM
cannot start.
When I try to start such an VM the engine only
reports that it cannot be started (failed to run VM
on hv1, hv2, hv3) with no further error. I looked
at engine.log and vdsm.log and there is also no
specific error, that the ISO isn't accessible.
PS:
- ovirt 3.3
- detaching the iso allows the vm to start of course.
