[ovirt-users] Ovirt 4.3 / New Install / NFS (broken)

2019-01-13 Thread Devin Acosta

I installed the latest 4.3 release candidate and tried to add an NFS mount
to the Data Center, and it errors in the GUI with “Error while executing
action New NFS Storage Domain: Invalid parameter”, then in the vdsm.log I
see it is passing “block_size=None”. Does this regardless if NFS v3 or v4.

[ovirt-users] oVIRT Node / Network Manager / oVirt 4.1

2017-07-31 Thread Devin Acosta

I noticed that for some reason when I am running oVirt node on my hosts and
disabled NetworkManager it appears that it kept turning itself back on, and
my understanding is that Network Manager should be disabled. I had to force
remove Network Manager in order to get it to stay disabled. I have been
seeing strangeness with my VM's where they disconnect, and where
hosted-engine keeps trying to non-stop migrate to another host. Just wanted
to first confirm about Network Manager and oVirt Node image.

Re: [ovirt-users] oVIRT 4.1 / iSCSI Multipathing

2017-07-17 Thread Devin Acosta

V.,

I am still troubleshooting the issue, I haven’t found any resolution to my
issue at this point yet. I need to figure out by this Friday otherwise I
need to look at Xen or another solution. iSCSI and oVIRT seems problematic.

Have you found any solution for this problem?

I’m using an FreeNAS machine to server iSCSI but I’ve the exactly same
problem. I’ve reinstalled oVirt at least 3 times during the weekend trying
to solve the issue.

At this moment my iSCSI Multipath tab is just inconsitent. I can’t see both
VLAN’s on “Logical networks” but only one target shows up on Storage
Targets.

When I was able to found two targets everything went down and I needed to
reboot the host and the Hosted Engine to regenerate oVirt.

I am using the latest release of oVIRT 4.1.3, and I am connecting a Dell
Compelent SAN that has 2 fault domains each on a separate VLAN that I have
attached to oVIRT. From what I understand I am suppose to go into “iSCSI
Multipathing” option and add a BOND of the iSCSI interfaces. I have done
this selecting the 2 logical networks together for iSCSI. I notice that
there is an option below to select Storage Targets but if I select the
storage targets below with the logical networks the the cluster goes crazy
and appears to be mad. Storage, Nodes, and everything goes offline even
thought I have NFS also attached to the cluster.

How should this best be configured. What we notice that happens is when the
server reboots it seems to log into the SAN correctly but according the the
Dell SAN it is only logged into once controller. So only pulls both fault
domains from a single controller.

Please Advise.

2017-07-14 Thread Devin Acosta

You can get my logs from:

https://files.linuxstack.cloud/s/NjoyMF11I38rJpH

They were a little to big to attach to this e-mail. Would like to know if
this is the similar bug that Richard indicated is a possibility.

[ovirt-users] oVIRT 4.1 / iSCSI Multipathing

2017-07-12 Thread Devin Acosta

I am using the latest release of oVIRT 4.1.3, and I am connecting a Dell
Compelent SAN that has 2 fault domains each on a separate VLAN that I have
attached to oVIRT. From what I understand I am suppose to go into “iSCSI
Multipathing” option and add a BOND of the iSCSI interfaces. I have done
this selecting the 2 logical networks together for iSCSI. I notice that
there is an option below to select Storage Targets but if I select the
storage targets below with the logical networks the the cluster goes crazy
and appears to be mad. Storage, Nodes, and everything goes offline even
thought I have NFS also attached to the cluster.

How should this best be configured. What we notice that happens is when the
server reboots it seems to log into the SAN correctly but according the the
Dell SAN it is only logged into once controller. So only pulls both fault
domains from a single controller.

Please Advise.

[ovirt-users] oVIRT 4.1 / iSCSI Multipathing / Dell Compellent

2017-07-11 Thread Devin Acosta

I just installed a brand new Dell Compellent SAN for use with our oVIRT
4.1.3 fresh installation. I presented a LUN of 30TB to the cluster over
iSCSI 10G. I went into the Storage domain and added a new storage mount
called “dell-storage” and logged into each of the ports for the target. It
detects the targets just right and the Dell SAN is happy, until a host is
rebooted at which point the iSCSI seems to choose to log into only one of
the controllers and not all the paths that it originally logged into. At
this point the Dell SAN shows only 1/2 connected and therefore my e-mail.

When I looked at the original iscsiadm session information after initially
joining to domain it shows correct connected to (1f,21,1e,20) ports.



tcp: [11] 10.4.77.100:3260,0 iqn.2002-03.com.compellent:5000d310013dfe1f
(non-flash)

tcp: [16] 10.4.78.100:3260,0 iqn.2002-03.com.compellent:5000d310013dfe1e
(non-flash)

After I reboot the hypervisor and it re-connects to the cluster it shows:

tcp: [1] 10.4.78.100:3260,0 iqn.2002-03.com.compellent:5000d310013dfe1e
(non-flash)

tcp: [2] 10.4.78.100:3260,0 iqn.2002-03.com.compellent:5000d310013dfe1e

tcp: [4] 10.4.77.100:3260,0 iqn.2002-03.com.compellent:5000d310013dfe1f
(non-flash)

What is bizarre is it shows multiple connections to the same IP but it
shows 2 connections to 1e, and 2 connections to 1f. It seems to selected
only the top controller on each fault domain and not the bottom controller
also.

I did configure a “bond” inside the iSCSI Multipathing of selecting only
the 2 VLANS together for the iSCSI. I didn’t select a target with it
because wasn’t sure the proper configuration for this. If I selected both
virtual and target port the cluster goes down hard.

Any ideas?

[ovirt-users] oVIRT 3.5 / Virtual Machine / 10GB possible?

2017-03-14 Thread Devin Acosta

We are running oVIRT 3.5, until one of vendors supports us moving to 4.0.
Our RHV hosts have 20GB aggregated NICs on the box, however our VM's I
notice only have 1GB NICs available. I do see that the Virtual machine is
using the "virtio-net-pci" device, is there a way to get this Virtual
Machine to have a 10GB NIC? When i run 'atop' on the RHV host I notice that
it claims the virtual NIC is hitting 100% utilization at times.

What methods do I have available to increase the 1GB NIC to something
higher hopefully to 10GB ?

2017-02-28 Thread Devin Acosta

I am running oVIRT 3.5.6 right now on Dell Blade Chassis, each oVIRT node
has 2 x 10 core processors, showing 40 VCPU cause of hyper-threading. We
are trying to figure out for a very log intensive application that requires
lots of specs what the optimal configuration would be to allow it to use
utilize all cores on the blade?  Is there advise on this? Like should we
disable hyperthreading? What's the general rule of thumb?

[ovirt-users] oVIRT / GlusterFS / Data (HA)

2017-01-24 Thread Devin Acosta

I have created an oVIRT 4.0.6 Cluster, it has 2 Compute nodes, and 3
Dedicated Gluster nodes. The Gluster nodes are configured correctly and
they have the replica set to 3. I'm trying to figure out when I go to
attach the Data (Master) domain to the oVIRT manager what is the best
method to do so in the configuration?  I initially set the mount point to
be like: gluster01-int:/data, then set in the mount options
"backup-volfile-servers=gluster02-int:/data,gluster03-int:/data", so I
understand that will choose another host if the 1st one is down but if i
was to reboot the 1st Gluster node would that provide HA for my Data
domain?

I also configured ctdb with a floating-ip address that floats between all 3
Gluster nodes, and I am wondering if I should be pointing the mount to that
VIP? What is the best solution with dealing with Gluster and keeping your
mount HA?

So some port got stuck on a box? Any idea what would cause this and what i
should do to remove it?

Marcin,Numan,Lance:

I really appreciate all the assistance that you have given me thus far. I
wanted to circle back on this topic, even though I sense I know what the
answer will be. ;) My Networking team keeps insisting that they want to
control DHCP from their side however yet still be able to create virtual
Layer 2 networks within oVirt. I understand that it sounds like OVN was
never meant for this kind of configuration. In the setup that we currently
have going for the most part Linux boxes are working if we set the MTU to
be lower around 1400, however with the Windows boxes we are getting very
strange behavior, sometimes we have to set the MTU low to as 1000, but then
the next day 1200 works. We aren't fully sure if it's just some strange
windows issue with the driver or what.

One question that was asked of me was if OVS/OVN supports like PMTUD, MTU
Protocol discovery? Also I'm suspecting if was to configure oVIRT to use
Neutron using OVS I would encounter the same issues I have now with the MTU
if they are trying to do DHCP from a virtual appliance on the network?

Any other comments or suggestions that you can provide on this?

Thanks again.

Lance,

It appears that firewalld was my issue, can you just confirm with me what
Ports should be opened for Geneve and OVN to work properly?

Marcin,

Also I noticed in your original post it mentions:

ip link - the result should include a link called genev_sys_ ...

I noticed that on my hosts I don't see any links with name: genev_sys_ ??
Could this be a problem?

[ovirt-users] oVIRT 4 / OVN / Communication issues of instances between nodes.

2016-12-02 Thread Devin Acosta

Note: When I configured vdsm-tool ovn-config, I passed it the IP address of
the OVN-Controller which is using the ovirtmgmt network, which is just one
of the NIC's on the nodes.

I am opening up new thread as this I feel differs a bit from my original
request. I have OVN which I believe is deployed correctly. I have noticed
that if instances get spun up on the same oVIRT node they can all talk
without issues to one another, however if one instance gets spun up on
another node even if it has the same (OVN network/subnet), it can't ping or
reach other instances in the subnet. I noticed that the OVN-Controller of
the instance that can't talk is logging:

Re: [ovirt-users] oVirt 4 and Neutron

2016-12-01 Thread Devin Acosta

I have manually created the RPM's successfully, I just want to clarify a
few items so I make sure I'm deploying this according to best practice.

I presume the OVN Controller should just be some VM that is on the
ovirtmgmt network, or is there a preferred place to install the OVN
controller software? I then also assume I install the OVN agents onto all
the oVirt Nodes. My take on this is that this OVN replaces the more complex
Neutron/OVS installation, and makes for a more simple deployment.  I see
that when you go to add the External Provider, does OVN Controller use
authentication, is there any information I would need to have besides
knowing which node it's on in order to add it to external provider? Would I
need to have any bridges or OVS configured on the nodes for this to work or
just install the services and get them configured and it just works?


Your assistance is appreciated.

Re: [ovirt-users] oVirt 4 and Neutron

2016-11-30 Thread Devin Acosta

Yaniv,

I am looking at the page that talks about ovirt-provider-ovn, and it sounds
like something I want to try. However the document seems to be not
complete, and I'm not sure i fully understand how it should be deployed.
When I downloaded the "ovirt-provider-ovn-driver-0-1.noarch.rpm" and try to
install on the oVIRT nodes it complains about needing other packages such
as:

- openvswitch-ovn-central
- python-openvswitch
- firewalld-system
- openvswitch-ovn-host

I don't see anywhere where it talks about getting access to the RPMS for
openvswitch-ovn-central. Also I presume like Neutron I would install OVN on
a Master node and then install some clients on the nodes? Can you provide
me additional information on this?

[ovirt-users] oVirt 4 and Neutron

2016-11-21 Thread Devin Acosta


oVirt Users:

My work is currently deploying oVirt 4.0.5 into our Development 
environment. I see there use to be a maintained Openstack Neutron image 
that could be used with oVirt to provide SDN functionality. I'm 
suspecting that the reason for the image no longer being maintained is 
because it became a hassle to keep updated and patched. From what I 
understand the current idea is to just point your oVirt installation to 
an already installed Openstack setup. I can easily install an image and 
install the latest Openstack (Keystone/Neutron) and then point oVirt to 
it, but I want to understand if that is the proper way to move forward. 
Is there a general consensus with the way oVirt is moving in regards to 
Software Defined Networking and Neutron in general? Just want to ensure 
I understand it clearly before just installing my own Neutron if there 
is going to be another method.


Any feedback is appreciated.
