[Users] Export not exporting the disk
by Juan Pablo Lorier
Hi,
I've already posted before but the thread went dead. If I export a
stoped vm with direct-lun disk, it creates the export without errors but
doesn't export the disk. I was told that it should.
How can I debugg this?

So is qemu-kvm-rhev from mentioned source RPM a drop-in replacement for
qemu-kvm from CentOS ? Would it make sense to install it instead of
qemu-kvm?

[Users] *SAN LUNs* thin-provisioning : Reclaiming block device storage
by Nicolas Ecarnot
[This post is *not* about *VM* thin-provisioning]
Hi,
Our setup is made of an Equalogic SAN (PS6100) connected via a dedicated
iSCSI network, an oVirt 3.3.0-4.el6 manager and CentOS nodes.
This is working fine (thank you all).
I usually create a LUN for the master storage domain, configure in
thin-provisioned mode on the SAN side, and fill it with VMs until it
reaches some 90%.
Then I create another LUN the same way, add it as an additional storage
domain, move some VM on it from the first domain and it's OK.
The issue there is I have no mean to reclaim any freed storage on the
master storage LUN. So the question (not *master* domain specific - any
storage domain is concerned) is how to reclaim space on these domains.
I began to have a closer look at how a storage domain is setup (PV, VG,
LVs). I also found some hints about some mount option (unmap) that could
be passed when mounting ext4 filesystems.
But I guess the issue is way more complex, as LVM may add a layer
between ext4 and the block device.
How is the LVM setup working? I saw there was one LV by disk (and some
metadata LVs), in one big VG in one big PV. Is the entire disk space
allocated for the PV, or is only a partial of it is used first, then an
extension (growing) is made each time some more space is needed by
adding VMs?
I have the opportunity to test and play with a test LUN in a test oVirt,
so I fear no crash. If the only answer is "Unavailable feature", it's
ok, but I just have to know.

LUN should be empty. ovirt will create a VG on it, and managed an LV per
disk/snapshot as needed.

just an empty LUN.

Hi,
I just updated the wiki a little, but I'm not sure my information
is 100% correct:
http://www.ovirt.org/Features/MomIntegration
especially regarding the status of the guest agent on
various operating systems (the info in the wiki is a mess and not
up-to-date).
so maybe someone can provide additional information regarding
ballooning of memory and the guest agent, I also updated the png
but didn't upload it, because it's not finished yet, feel free
to improve the dia-shape yourself (see the attachment) :-)
PS: Maybe it would be cool to store such graphical overviews
in their source-format in a git or in the wiki, for easier updating
through other people?
PPS: Is this the right ML for this kind of info or should I register
for Infra or something else?

[Users] Problem adding an RHEL node/host
by Bob Doolittle
Hi,
I'm trying to follow the Quick Start guide, and I can't seem to add a
host. I am running oVirt 3.3 on F19 for the engine. The node is RHEL
6.4, subscribed to RH channels and fully updated:
# yum repolist
Loaded plugins: product-id, refresh-packagekit, rhnplugin, security,
: subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
This system is receiving updates from RHN Classic or RHN Satellite.
repo id repo name status
epel Extra Packages for Enterprise Linux 6 - x86_64 9,972
glusterfs-epel GlusterFS is a clustered file-system capable of sca 11
glusterfs-noarch-epel GlusterFS is a clustered file-system capable of sca 2
ovirt-stable Stable builds of the oVirt project 212
rhel-x86_64-server-6 Red Hat Enterprise Linux Server (v. 6 for 64-bit x8 11,114
repolist: 21,311
The install fails, and when I look at the host-deploy log it appears to
be due to a failure for Yum to find a dependency.
At Matt Curry's suggestion, I added the 'epel' repository (not mentioned
in QS Guide), which I think resolved some dependencies, but I still fail
as follows:
2013-11-08 13:48:49 ERROR otopi.context context._executeMethod:146 Failed to execute stage 'Package installation': [u'vdsm-4.12.1-4.el6.x86_64 requires sanlock-python', u'vdsm-4.12.1-4.el6.x86_64 requires libvirt-lock-sanlock', u'vdsm-4.12.1-4.el6.x86_64 requires sanlock >= 2.3-4']
As far as I can tell by googling around, sanlock belongs to the ovirt
project. So where should it be coming from?
Is something wrong with ovirt-stable? I am using:
[ovirt-stable]
name=Stable builds of the oVirt project
baseurl=http://ovirt.org/releases/stable/rpm/EL/$releasever/
enabled=1
skip_if_unavailable=1
gpgcheck=0
I did a "yum clean; yum mkcache" just prior to initiating the Host Add
from the web interface. Any suggestions?
Thanks,
Bob
