ovirt 4.1: migrate vm to node 2 results in lost connectivity
by yayo (j)
Hi all,
I have a simple 3 node ovirt 4.1 gluster. All works fine but when I create
or move a vm to node 2 the connection is lost, if I move the vm back to
node 1 all works fine again. Looking to ovirt engine, network seems
identical (for now I have only ovirtmng network). If I ping something from
node 2, ping works fine (internet in general). Where can I check also?
thank you

Smtp configuration for notification
by wodel youchi
Hi,
When we install the vm engine, in the configuration process we are asked to
give an smtp server and email addresses for notification but then nothing.
When we looked to the event notification configuration we found this
file ovirt-engine-notifier.conf and we thought that the first configuration
was there but since the notification service was disabled notifications
were not working, but No, there was no configuration on that file we had to
modify it and now notifications are working.
The question is : is the first smtp configuration used ? If yes, when? Can
we test it ? And if we want to modify it, where the configuration is stored
?

Regenerating SSL keys
by Jamie Lawrence
The key generated by the engine install ended up with a bad CN; it has a five-digit number appended to the host name, and no SAN.
I've lived with this through setup, but now I'm getting close to prod use, and need to clean up so that it is usable for general consumption. And the SPICE HTML client is completely busted due to this; that's a problem because we're mostly MacOS on the client side, and the Mac Spice client is unusable for normal humans.
I'm wary of attempting to regenerate these manually, as I don't have a handle on how the keysare used by the various components.
What is the approved method of regenerating these keys?

Ovirt nested in VMware
by Mark Duggan
Hi everyone,
>From reading through the mailing list, it does appear that it's possible to
have the ovirt nodes/hosts be VMware virtual machines, once I enable the
appropriate settings on the VMware side. All seems to have gone well, I can
see the hosts in the ovirt interface, but when I attempt to create and
start a VM it never gets past printing the SeaBios version and the machine
UUID to the screen/console. It doesn't appear to try to boot from the hard
disk or an ISO that I've attached.
Has anyone else encountered similar behaviour?
Are there additional debug logs I can look at or enable to help further
diagnose what is happening?
Thanks

Backup ovirt engine

I'm not sure how to backup the Ovirt engine to an external hard drive. I plan on updating to Ovirt 3.6 (as I currently have 3.5), then centOS 7 (currently using centOS 6), and after updating the Ovirt 3.6 to 4.0, but I want to have a backup file on an external drive before going through with the updates.
Thanks

Self-Hosted Engine Deploy - CephFS Not a Storage Option
by Michael Poat
This is a multi-part message in MIME format.
--------------EDA4F48E9FCD0C6C900C6E59
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 7bit
Hello,
I currently have a 30 node ~200TB Raw Ceph storage primarily used as a
CephFS POSIX Complaint storage for my enclave. Currently I am working on
setting up a dual node High Availability ovirt 4.1 cluster. Considering
avoiding any single points of failure, I would like to use CephFS as my
storage domains and want to use the Self-Hosed Engine feature.
When setting up the Self-Hosted Engine and reaching the steps for
"Configuring Storage", POSIX Compliant FS or CephFS is not an option...
Prompt:
|During customization use CTRL-D to abort. Please specify the storage you
would like to use (glusterfs, iscsi, fc, nfs3, nfs4)[nfs3]:|
Is there a work around for this or any future POSIX FS/CephFS Support
for the Self-Hosted-Engine setup? I was able to create CephFS Domains
within Ovirt and they work great. I was also wondering if it would be
possible to migrate the self-hosted VM to the CephFS storage but this
would require shutting down the VM itself, sort of a catch-22.
Thanks,
-Michael

Setting up GeoReplication
by Jim Kusznir
Hi All:
I've been trying to set up georeplication for a while now, but can't seem
to make it work. I've found documentation on the web (mostly
https://gluster.readthedocs.io/en/refactor/Administrator%20Guide/Geo%20Re...),
and I found
http://blog.gluster.org/2015/09/introducing-georepsetup-gluster-geo-repli...
Unfortunately, it seems that some critical steps are missing from both, and
I can't figure out for sure what they are.
My environment:
Production: replica 2 + arbitrator running on my 3-node oVirt cluster, 3
volumes (engine, data, iso).
New geo-replication: Raspberry Pi3 with USB hard drive shoved in some other
data closet off-site.
I've installed rasbian-lite, and after much fighting, got
glusterfs-*-3.8.11 installed. I've created my mountpoint (USB hard drive,
much larger than my gluster volumes), and then ran the command. I get this
far:
[ OK] georep.nwfiber.com is Reachable(Port 22)
[ OK] SSH Connection established root(a)georep.nwfiber.com
[ OK] Master Volume and Slave Volume are compatible (Version: 3.8.11)
[NOT OK] Unable to Mount Gluster Volume georep.nwfiber.com:engine-rep
Trying it with the steps in the gluster docs also has the same problem. No
long files are generated on the slave. Log files on the master include:

I don't know what to make of that.
On a whim, I thought that perhaps the georep setup does not set up the
remote volume (I assumed it would, I thought that was what the ssh was
required for, and none of the instructions mentioned create your
destination (replication) volume. So I tried to create it, but it won't
let me create a volume with replica 1. this is already a backup, I don't
need a backup of a backup. This further supported my thought that the
volume needs to be created by the georep setup commands.
Where am I wrong / what do I need to do to fix this?
