Hi,
I'm happily using our research cluster in Italy via gluster, and now I'm
trying to hotplug a ceph disk on a VM of my cluster, without success.
The ceph cluster is managed via openstack cinder and I can create
correctly the disk via ovirt (3.6.6.2-1 on CentOS 7.2).
The problem comes when trying to hotplug, or start a machine with the
given disk attached.
In the vdsm log of the host where the VM is running or starting I see
the following error:
jsonrpc.Executor/5::INFO::2016-05-30

Anyone got it working?
Thanks,
Alessandro

Now, I'm trying a full yum update and getting :

I have disable ovirt-3.6-epel, because I already use epel, is it the =

What should I do ? I don't think removing ovirt-engine-tools is a =

One RHEV Virtual Machine does not Automatically Resume following Compellent SAN Controller Failover
by Duckworth, Douglas C
Hello --
Not sure if y'all can help with this issue we've been seeing with RHEV...
On 11/13/2015, during Code Upgrade of Compellent SAN at our Disaster
Recovery Site, we Failed Over to Secondary SAN Controller. Most Virtual
Machines in our DR Cluster Resumed automatically after Pausing except VM
"BADVM" on Host "BADHOST."
In Engine.log you can see that BADVM was sent into "VM_PAUSED_EIO" state
at 10:47:57:
"VM BADVM has paused due to storage I/O problem."
On this Red Hat Enterprise Virtualization Hypervisor 6.6
(20150512.0.el6ev) Host, two other VMs paused but then automatically
resumed without System Administrator intervention...
In our DR Cluster, 22 VMs also resumed automatically...
None of these Guest VMs are engaged in high I/O as these are DR site VMs
not currently doing anything.
We sent this information to Dell. Their response:
"The root cause may reside within your virtualization solution, not the
parent OS (RHEV-Hypervisor disc) or Storage (Dell Compellent.)"
We are doing this Failover again on Sunday November 29th so we would
like to know how to mitigate this issue, given we have to manually
resume paused VMs that don't resume automatically.
Before we initiated SAN Controller Failover, all iSCSI paths to Targets
were present on Host tulhv2p03.
VM logs on Host show in /var/log/libvirt/qemu/badhost.log that Storage
error was reported:
block I/O error in device 'drive-virtio-disk0': Input/output error (5)
block I/O error in device 'drive-virtio-disk0': Input/output error (5)
block I/O error in device 'drive-virtio-disk0': Input/output error (5)
block I/O error in device 'drive-virtio-disk0': Input/output error (5)
All disks used by this Guest VM are provided by single Storage Domain
COM_3TB4_DR with serial "270." In syslog we do see that all paths for
that Storage Domain Failed:
Nov 13 16:47:40 multipathd: 36000d310005caf000000000000000270: remaining
active paths: 0
Though these recovered later:
Nov 13 16:59:17 multipathd: 36000d310005caf000000000000000270: sdbg -
tur checker reports path is up
Nov 13 16:59:17 multipathd: 36000d310005caf000000000000000270: remaining
active paths: 8
Does anyone have an idea of why the VM would fail to automatically
resume if the iSCSI paths used by its Storage Domain recovered?
Thanks
Doug

Thank you, Gianluca.
The OpenStack integration with ScaleIO absolutely warrants further investigation on my part. It looks like a rather recent addition to ScaleIO, so I'll need to run that in a lab setting for a while. It looks like the best long term option.
In the meantime, I think that I might be able to get this working by exposing a few, larger LUNs via NFS running on the ScaleIO nodes. I lose granular snapshot capabilities and MPIO in ScaleIO that way, though.
If I need real MPIO-type performance on a VM, I guess I can just install the ScaleIO client in the guest and access the LUN that way.
Also, I plan on learning more about the iSCSI Direct LUN logic in oVirt to see if there is enough similarity between the output of iscsiadm and the ScaleIO SDC/SDS utilities to request a direct ScaleIO integration feature. That might be a nice little side project for a while.
Have a great day,

I don't know much of ScaleIO, but at least since Liberty release it can be configured as a cinder backend driver in Openstack
http://docs.openstack.org/liberty/config-reference/content/ScaleIO-cinder...
http://docs.openstack.org/mitaka/config-reference/block-storage/drivers/e...
So the more "natural" way that comes to mind is to interface oVirt with cinder and configure ScaleIO in cinder in similar way as with Ceph backend
http://old.ovirt.org/Features/Cinder_Integration
But this implies configuring Openstack too and also I don't know how the security part (see ceph authentication in above link), if present in ScaleIO, could be managed

Changing Cluster CPU Type in a single Host with Hosted Engine environment
by Ralf Braendli
Hi
I have the Problem that I selected the wrong CPU Type throw the setup process.
Is it posible to change it without an new installation ?
We have a single Host with a Hosted Engine installed.
With this installation I can’t put the Host into Maintenance Mode because the Hosted Engine will run on this Host.
The Version we us is 3.5.5-1

How to automate the ovirt host deployment?
by Arman Khalatyan
Hi, I am looking some method to automate the host deployments in a cluster
environment.
Assuming we have 20 nodes with centos 7 eth0/eth1 configured. Is it
possible to automate installation with ovirt-sdk?
Are there some examples ?
Thanks,
Arman.

Problem upgrading Host from 3.5 to 3.6 in Centos 6
by Giulio D’Ippolito
Hi all,
We are having a bit of hard time trying to upgrade oVirt from 3.5 release
to 3.6.
This is our setup:
- All the hosts are running Centos 6.7
- The engine is a standalone machine
- The engine is running Centos 6.7
- Upgrading the engine from 3.5.x to 3.6.6 was successful
Now the problem was when we were trying to upgrade the hosts to 3.6
release.
We put one host in maintenance and we were expecting the "Upgrade" option
to be available but it wasn't.
We have imported the 3.6 repository to the host and performed a "yum clean
all" and a "yum update" to see which packages were marked to be upgrade.
No packages in the oVirt 3.6 repository were available to upgrade.
Then we tried to use the "Reinstall" option available in the GUI
The reinstall failed with the following issue:
*2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager

['qemu-kvm-rhev-tools conflicts with

We fixed the issue via removing the qemu-kvm-tools and running the
"Reinstall again".
But effectively this was the only package that was installed/upgrade by
running "Reinstall" again.
I can see from the repository
http://resources.ovirt.org/pub/ovirt-3.6/rpm/el6/x86_64/ that not many
packages are available in this repository for Centos 6.
For example vdsm package is still version vdsm-4.16.30-0.el6 which was
installed in oVirt 3.5
Is this the expected outcome of the upgrade in the host?
Thanks,
Giulio
