Hosted Engine installation + GlusterFS cluster
by Artem Tambovskiy
Another yet attempt to get a help on hosted-engine deployment with
glusterfs cluster.
I already spend a day trying to get bring such a setup to work with no
luck.
The hosted engine being successfully deployed but I can't activate the
host, the storage domain for the host is missing and I can't even add it.
So either something went wrong during deployment or my glusterfs cluster
doesn't configured properly.
That are the prerequisites for this?
- glusterfs cluster of 3 nodes with replica 3 volume
- Any specific volume configs?
- how many volumes should I prepare for hosted engine deployment?
Any other thoughts?
Regards,
Artem

Re: [ovirt-users] glusterFS is not independent?
by Johan Bernhardsson
Gluster would be to overcomplicate this if you only want local storage
on both to be reachable over the network.
Simplest way is to setup an nf server on both nodes and create a
storage domain for each.
Gluster is a way to secure your data and replicate them over several
nodes. so that if one node goes down or explodes you always have the
data replicated to other nodes. Running a single brick gluster volume
is not recomended.

glusterFS is not independent?
by Jon bae
Hello,
I'm very new to oVirt and glusterFS, so maybe I got something wrong...
I have the oVirt engine installed on a separate server and I have also two
physical nodes. On every node I configure glusterFS, the volume is in
distribution mode and have only one brick, from is one node. Both volumes I
also add to its own storage domain.
The idea was, that both storage domains are independent from each other,
that I can turn of one node and only turn it on, when I need it.
But now I have the problem, that when I turn of on node, both storage
domains goes down. and the volume shows the the brick is not available.
Is there a way to fix this?

Jonathan

Unable to change cluster compatibility version
by Logan Kuhn
Hi
We've recently upgraded from 4.0.6.3 to 4.1.6 and we've upgraded all of our
clusters except one to 4.1 without issue. The one we are having trouble
with is the big important one (of course).
The error we get in the interface is:
Error while executing action:
Cannot change cluster version since following VMs are previewing snapshots:
mail-archive1
The log error is a little verbose seeming, so it's attached. I'm not
really sure what it means or how to fix it....

Messed up upgrade to 4.2. Solution badly needed.
by Marcin Jessa
Hi guys.
I have VM with hosted engine and a two node setup. When beta came out I was “OH! New shiny tech! Let’s try it!”. You all know the feeling.
Unfortunately the upgrade process did not go as expected.
I created a backup of my 4.1 installation and started to upgrade the VM. All went well. I then migrated all the running VMs to my second node put the cluster in global maintenance mode and updated one of the nodes.
Then I run hosted-engine —upgrade-appliance on the node but it fails:
[ ERROR ] Failed to execute stage 'Environment customization': exceptions must be old-style classes or derived from BaseException, not str
The log file says:
2017-11-03 13:12:48,259+0100 DEBUG otopi.context context._executeMethod:143 method exception
Traceback (most recent call last):

2017-11-03 13:12:48,261+0100 DEBUG otopi.context context.dumpEnvironment:835 ENVIRONMENT DUMP - END
I can login to the hosted engine but the nodes are down, the VMs are down and the storage is not connected.
Can you please advice what to do now?
Is there a way to upgrade my setup?
Should I disconnect my second node, which is also upgraded to 4.2 now and try to install hosted engine from scratch?
Anything else I can do to save my VMs?
Cheers
Marcin.

ovirtmgmt network
by Arsène Gschwind
This is a multi-part message in MIME format.
--------------4ED07EBEEF5FDCFA459DA49E
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 8bit
Hi,
I have a question about ovirtmgmt network.
When deploying Hosted-Engine it creates ovirtmgmt bridge on top of main
nic of the host. This means the HE will be connected to the same network
as the main Host connection. Is it possible to separate those subnet,
let say I would have something like
Host:
IP: 10.0.a.b (VLAN a untagged) The host has an IP address on that interface
GW: 10.0.a.gw
Then i would have a tagged VLAN on top of that interface :
IF2 : 10.0.c.x (VLAN c tagged) The host has no IP address on that interface
GW: 10.0.c.gw
Would it be possible to have the HE connected on IF2, if Yes how do we
deploy such a setup?
Thanks for any hint.
Rgds,
Arsène

Advise needed: building cheap HA oVirt cluster with just 2 physical servers
by Artem Tambovskiy
Looking for a design advise on oVirt provisioning. I'm running a PoC lab on
single bare-metal host (suddenly it was setup with just Local Storage
domain) and
no I'd like to rebuild the setup by making a cluster of 2 physical servers,
no external storage array available. That are the options here? is there
any options to build cheap HA cluster with just 2 servers?
Thanks in advance!
