This is the first time I've run through an 'upgrade'=2C so I'm very new to =
export domains=2C and I'm having some trouble getting one connected to 3.3.=
I had hoped to add this to the wiki=2C but it hasn't been as straightforwa=
rd as I thought.
On my oVirt 3.2 install=2C I created a NFS export (/var/lib/exports/DAONE) =
and exported my VMs to it. I created a tarball of everything in DAONE=2C an=
d then formatted the system and installed Fedora 19=2C and then oVirt 3.3. =
Created the NFS resource (/var/lib/exports/DAONE)=2C extracted the tarball=
=2C and followed these directions to clear the storage domain. However when=
I try to add it=2C the webadmin reports the following error:
"Error while executing action New NFS Storage Domain: Error in creating a=
=0A=
Storage Domain. The selected storage path is not empty (probably =0A=
contains another Storage Domain). Either remove the existing Storage =0A=
Domain from this path=2C or change the Storage path)."
Any suggestions? I wonder if anything changed for 3.3 that need to be in th=
e instructions?
I also tried making another export domain (/var/lib/exports/export) and dum=
ping everything into the UUID under that=2C but no VMs showed up to import.

Re: [Users] could not add iscsi disk in ovirt.
by Dafna Ron
you don't have to reconfigure engine to create iscsi pool.
you can create multiple pools, the only limitation is that you will need
a host for the each of the DCs.
but you can move one host from one DC to another...
so if you have 2 hosts just create a new DC and move one of the hosts
there.
I think that the direct lun is only for iscsi and fiber but I can give
you a 100% certainty answer on Monday.
I don't think its supported for NFS... I can check for you on Monday for
sure.

[Users] oVirt 3.3 and Neutron
by Riccardo Brunetti
Dear oVirt users.
I'm trying to setup oVirt 3.3 using an OpenStack Neutron existing
service as network provider.
It works pretty well: I can use the networks defined in Neutron, import
them and when I launch VM instances from oVirt they get an internal-IP
address from Neutron.
A can also associate a floating IP to the Neutron port and get inbound
connectivity for the virtual machine.
The problem is that if I shutdown the VM (both from inside the VM itself
and from the oVirt WEB GUI) the association port/internal-IP/floating-IP
is lost and when the VM is booted again It will get a different
internal-IP on a different port and I have to manually re-associate the
floating-IP.
Is there a way to keep the IP addresses when the VM is simply shutted
down and not deleted? This is the behavior when using OpenStack: if I
poweroff the VM, the IPs are kept for the future.
Moreover: can you confirm that in oVirt 3.3 there is still no support
for the Neutron security rules?
Thank you very much
Best Regards
Riccardo

[Users] Bottleneck writing to a VM w/ mounted GlusterFS
by Stefano Stagnaro
Hello,
I'm testing oVirt 3.3 with GlusterFS libgfapi back-end. I'm using a node for engine and one for VDSM. From the VMs I'm mounting a second GlusterFS volume on a third storage server.
I'm experiencing very bad transfer rates (38MB/s) writing from a client to a VM on the mounted GlusterFS. On the other hand, from the VM itself I can move a big file from the root vda (libgfapi) to the mounted GlusterFS at 70MB/s.
I can't really figure out where the bottleneck could be. I'm using only the default ovirtmgmt network.
Thank you for your help, any hint will be appreciated.
Regards,

[Users] Gluster NFS Replicate bricks different size
by Andrew Lau
I've mounted a gluster 1x2 replica through NFS in oVirt. The NFS share
holds the qcow images of the VMs.
I recently nuked a whole replica brick in an 1x2 array (for numerous other
reasons including split-brain), the brick self healed and restored back to
the same state as its partner.
4 days later, they've become inbalanced. The direct `du` of the /brick are
showing different sizes by around 20GB. I can see at brick level how some
images are not the same size. I don't think this is normal, but I can't see
anything to point what could be the issue.
gluster volume heal STORAGE info
gluster volume heal STORAGE info split-brain
Shows no issues.
Any suggestions?
Cheers,
Andrew.

Re: [Users] could not add iscsi disk in ovirt.
by Dafna Ron
the output is empty in both your outpit and the logs.
This is the part in the log that shows that you do not have any devices:
return: []
when you create a new disk and select the NFS DC- can you please send me
the screen shot of that?

[Users] could not add iscsi disk in ovirt.
by Saurabh
Hi guys,
I am running ovirt with NFS as storage pool. Everything is working quite
fine for me. The only problem is I could not add the a new iscsi disk in
Disk tab.
When I go to the Disk tab there is an option of adding new disk from
internal storage and another option is add External (Direct Lun). When I
opt for the External (Direct LUN), I am able to discover the Lun but
could not log in to that lun using the ovirt web console. Whereas when I
try to login to that lun using the isciadm in command line I am able to
login.
Any help??
