Thanks, I have managed to get 2 systems to talk to each other, 1 laptop
providing the storage and one 'desktop' providing the horsepower/room,
in a HE NFS setup.
Will bring some cabling/switch and only need a (or 2) monitor with power.

See you all Saturday and maybe friday evening downtown??

All modern browsers work fine. It has todo with the fact that compiling
ovirt-engine for all browser versions is taking to much resources. It
has to do with how ovirt uses GWT if I'm correct.
Searching the mailinglist for this message + GWT will probably reveal a
message from a developer with a bit more info than I can remember.

As suggested amend your vdsm.conf to use replica 2. There should be a
vdsm.conf.rpmnew in /etc/vdsm which documents all parameters. Don't
forget that if you use replica 2 that you need to take care of
split-brain situations!

Trying a yum upgrade barfs with a depency problem trying to update 2 or
3 ovirt related packages, one of them ovirt-hosted-engine, that was

[ovirt-users] Disappearing vm.conf

[noc]

Hi All,

I'm reinstalling hosted-engine on my F22 laptop and I'm making progress.
With beta3 I couldn't get it installed, with beta5 it installed and I
could go into the webui but I had to shutdown my laptop and get some
sleep :-)
Next morning the hosted-engine didn't start. Running 'hosted-engine
--vm-status' tells me I need to deploy first. Looks like its a virgin
system. Looking at what hosted-engine does I found out that
/var/run/ovirt-hosted-engine-ha/vm.conf is missing. In another thread
its mentioned that it now lives on the storage domain but I couldn't
find it there, nothing resembles it.
Question is: how did engine get started and why is that vm.conf now missing.

Logs are available later today if needed.

You could also use elrepo kernels and stay on Centos6 but with a much
newer kernel. Have been running those for quite a while and haven't had
any problems with it.

I'm sorry but I seem to have no problem after all. If I look at the
report @09:00 then I'll see that it plots data upto about 07:00 and that
is what threw me off. I checked the reports about an hour after upgrading.

Thanks to Vijay its working now. Big omission on my side for not double
checking the options on the volumes used.
So bottom line: both el6 and el7 builds pass the 'startup VM' test, now
to some more serious testing.

If you don't use multipath then add a blacklist section to your
multipath.conf, something like this:
blacklist {
wwid "*"
}

Now, if you do use multipath you can whitelist the paths that you want.

Some scripting around ovirt-shell -f or -E should enable you to start

Sorry, forgot to install vdsm-gluster. Starting the VM on an el6 host
now works and still the same line with the port=0 so that doesn't seem
to matter.

OK, back to setting up a el6 host except when you generate a el7 version
too which would be awesome 8-) .

I did a quick setup of a nestedvt el6 host and, tried to, ran a vm on it
with a disk on a glusterfs SD and the following is part of the output
taken from vdsm.log when the VM starts up.







   
730aac8b-3233-4d28-8245-6c2bb3269a97




The VM doesn't start but that can be caused by my L2 virt OR that the
 is wrong. Shouldn't there be a port in
the 24007 or 49152 range?

Will try the F20 build on my home system and see if that goes better.

Thanks for the help sofar,

That would be nice too. Forgot that I updated my test env to el7 to see

I experimented a little more and found that if I create a VM in oVirt on
a glusterfs storage domain and start it, it won't use libgfapi, BUT if I
use virsh on the host where the VM runs and then add a disk the libgfapi
way the VM will see the disk and can use it. So the underlying infra is
capable of using libgf but oVirt isn't using it. Thats where the patch
comes in I think but I can't get it to work.

Q: how do I test that patch

I'm able to get around gcc/patch/git etc so don't need a n00b step by
step but a little how to get started is very welcome.

Thanks in advance,

Not needed. If you have created your networks then goto to the hosts
tab, select your host, select the Network Interfaces tab and hit Setup
Host Networks.
You'll get a window where you can drag and drop your defined networks to
an interface and define properties for them.

No problem with the questions, oVirt tries to solve a complex problem
and sometimes its easy to forget that one had the same problems a whole

[ovirt-users] Latest seabios in F19

[noc]

Just a FYI

I just upgraded my setup @home to 3.4.4 and part of the upgrade is a
seabios-bin upgrade to seabios-bin-1.7.3.1-1.fc19.noarch which seems to
contain a problem since I can't start any Windows7 VMs anymore.
Downgrading to seabios-bin-1.7.2.2-3.fc19.noarch solves the Win7 boot
problem

I use a Synology (DS211j and now DS214play) at home and have my storage
for oVirt on it and no problems with 36:36.
I think I modified /etc/exports after creating it so that it keeps the
36:36 permissions.

Hi Nathanaël,

happy to assist :) hope it will work in first run:

1) install the proxy and ovirtsdk.
2) put attached file in the right place (according to docs: ".../plugins"), 
make sure to edit the file with your ovirt's ip, user@domain and PW.
3) restart proxy service.
3) use config tool to configure ovirt-engine:
* "ExternalSchedulerServiceURL"="http://:18781/"
* "ExternalSchedulerEnabled"=true
4) restart ovirt-engine service.
5) under configure->cluster_policy see that weight function 
memory_even_distribution was added (should be in manage policy units or /sth- you 
will see it in the main dialog as well).
6) clone/copy currernt cluster's used cluster policy (probably none - prefer it 
to have no balancing modules to avoid conflicts), name it 'your_name' and 
attach memory_even_distribution weight (you can leave it as the only weight 
module in weight section to avoid configuring factors).
7) replace cluster's cluster policy with newly created one.

try it out and let me know how goes :-)



Ok, progress of some sort :-)

I added the weight function to the cluster and when I replace my dns 
name with localhost in ExternalSchedulerServiceURL then engine.log shows 
that it can contact the scheduler. I expected a rebalance but nothing 
happened. Stopping and starting a VM does provoke a reaction, an error :-(


From the scheduler.log I see that engine contacts it and pushes some 
information, the log also shows that some information is returned and 
then there is a big error message in the log of engine.

3) restart proxy service.
3) use config tool to configure ovirt-engine:
* "ExternalSchedulerServiceURL"="http://:18781/"

The scheduler proxy listens to localhost:18781, none of ips that can be
filled here will be reached on that port.

you config ovirt engine with the ip of the proxy, or I'm missing sth.
ovirt communicates with the proxy and not the other way around.


I'm following this and found out that ovirt-scheduler-proxy only listens 
on localhost so you'll need to adjust accordingly.

Create a second cluster named 'Storage' :-) and make sure the virt

storage hosts to this cluster. Hopefully during the install it won't 
complain about the virt bits. I run such a setup but my storage hosts

Assuming you're  using oVirt-3.3.2 which provides .vv files you need to 
install remote-viewer.
Download and install 
https://fedorahosted.org/released/virt-viewer/virt-viewer-x64-0.5.6.msi 
and when you're asked what todo with the .vv file browse to where you 
have virt-viewer installed and choose remote-viewer as the handler of 
.vv files.

It will handle spice and vnc console.

Had one of the groups come to me at work this week and request a

that they
really only need a multi-hypervisor setup where they can spin up
VMs for
their research projects. The VMs should be fairly long-lived, and
will have
persistent storage. Their other request is that the storage should
be local
on the hypervisor nodes (they plan to use Intel servers with 8-10
2TB drives
for VM storage on each node.) They desire this in order to keep
the VM I/O
local - they do not have a SAN of any sort anyhow, and they do not
care
about live migration, etc


@Will
If the installation ends, either with or without error, it will give you 
a log location. Upload the log to a paste.bin and mail the link.


@Gabi,
There should be more info in either the vdsm.log on the SPM server or in 
the engine.log on the engine server, see above for lettings us know what 
the error is.


Having installed oVirt, probably dozens of times, I have some guidelines:
- temporarily disable firewalld/iptables (if all works, enable should 
still work, scripts with rules are generated and location is given)
- make selinux permissive either via setenforce 0 (until next boot) or 
via /etc/selinux/config ( survives reboots), dont disable it!
- make sure fqdn work in both directions between engine and host(s) 
(either using /etc/hosts or DNS)

- make sure NetworkManager is disabled and network enabled

Hi,

I would prefer to keep using SSL if possible.
Just guessing but I don't think that your fqdn is localhost in 
your certs. Use your fqdn for the url variable.


Good thought. But now I am getting:

Some searching indicates that my keys and certs need to be in pem 
format, so maybe I have to convert them before use? Any tips on 
how to do that?


What happens if you leave out the ca_file/key_file/cert_file 
variables?
I just played around with ovirt-shell and made a .ovirtshellrc 
file, on the engine, and don't remember setting these and I could 
login and run scripts
Can't access my test environment right now so this is also a shot 
in the dark.


That's what I tried first. I get:
error: server CA certificate file must be specified for SSL secured 
connection.


And if I don't specify https I get:
error: No response returned from server. If you're using HTTP protocol
against a SSL secured server, then try using HTTPS instead.


OK. Here is what I did:
On ovirt-engine: wget https://engine_fqdn/ca.crt --no-check-certificate
and used the following .ovirtshellrc

[cli]
autoconnect = True
autopage = True
[ovirt-shell]
username = admin@internal
timeout = -1
extended_prompt = False
url = https://engine_fqdn/api
insecure = False
filter = False
session_timeout = -1
ca_file = /root/ca.crt
dont_validate_cert_chain = False
key_file = None
password = **
cert_file = None


Something must be different about our setups. This is where I started.

In both cases, either "insecure = True" or when I specify the ca_file 
only, I get:

error: [401] - Unauthorized, HTTP Status 401

The one difference is that you are using "ca_file = /root/ca.crt" 
whereas I am using "ca_file = ca.pem".


I can't seem to find any .crt files in the /etc/pki/ovirt-engine area 
(or, for that matter, in the /etc/pki/vdsm area on the node).

You have missed the step where I downloaded ca.crt with wget :-)

I am trying to set up a testing network using o-virt, but the
networking is refusing to cooperate.  I am testing for possible use in
two different production setups.

My previous experience has been with VMWare.  I have always set up a
single bridged network on each host.  All my hosts, VMs, and non-VM
computers were peers on the LAN.  They could all talk to each other,
and things worked very well.  There was a firewall/gateway that
provided access to the Internet, and hosts, VMs, and could all
communicate with the Internet as needed.

o-virt seems to be compartmentalizing things beyond all reason.
That is a way to use oVirt, but the following simple setup should work 
and give you a way to check against your setup.


I have two setups, one at home and one at work. The one at home is a 
setup of 2 hosts and one of those is a hacked up host/engine.
engine/host1: standard fedora19 kde install, static ip (192.168.1.11) 
configured with my NAS (192.168.1.16) as dhcp/dns server and my internet 
router (192.168.1.254) as gateway
Just make sure that NetworkManager is off and that your interfaces are 
not NM managed, network on.
This was a allinone setup but I got a NAS with NFS so I turned my aio 
setup into a engine/host system. It has problems with that but nothing 
network related.


Host2: same as above but without the engine install, ip:192.168.1.22, gw 
192.168.1.254 DNS:192.168.1.16.


How does it all come together?
Well in your case, and mine if I were to start over, start with a static 
network which is NOT managed by NetworkManager. Use either Fedora or 
Centos which ever you more comfortable with and it also depends on 
whether you want to test/use all the features in oVirt. Currently, there 
are a few features not available in Centos because the versions of 
libvirt/kvm/qemu/gluster are too old in Centos.
Install ovirt-engine on your first 'server', probably choose NFS as your 
storage domain, either on your engine server or from somewhere else on 
your network. Make sure its nfs-v3 and not v4!, local default is v4!
Make sure that ip addresses on you network are resolvable, either 
through /etc/hosts or through DNS! Engine-setup will complain if this 
doesn't work, using localhost will not work either!
On the engine server there will be no bridge and nothing will change the 
network config.


Next the first host.
Prepare the host in a similar way you did the engine server. You can 
choose a minimal install of either Centos or Fedora or install a full 
desktop but make sure that ips are static and NOT managed by 
NetworkManager, hostname resolvable, ovirt repo available.


From the webui add your prepared host and if everything went OK you'll 
see that on that host you will now have a bridge, ovirtmgmt, which acts 
as the primary interface.
Create a VMs and choose ovirtmgmt as a network for its nics, can't 
choose anything else. Either give the VMs a static address or use a dhcp 
server but the VMs should be able to talk to each other, to the host(s), 
the engine and to the internet.


Every host that you add after the first will also has its network turned 
into a bridge, ovirtmgmt, and communication/migration/display/etc will 
take place over this network. One caveat, storage domain mapping is from 
the host to the storage, the engine, if it is NOT the NFS server, 
doesn't have to have access to the storage.


If you have servers with more that 1 nic then you can create additional 
networks using the webui of oVirt and assign these to clusters and to VMs.


If you need vlans to coexist with ovirtmgmt on the same physical nic, I 
think that is possible but haven't tried it myself. In theory you need 
to setup the network first outside of oVirt, including you vlan 
structure and then install ovirt.


Some concepts:
oVirt engine: is just the manager, does 'nothing' related to running VMs 
itself. You can turn it off and all hosts with their VMs will keep 
running. You just can't start new ones, in short manage them.
oVirt host: is the real workhorse and is managed using oVirt-engine. 
Runs VDSM which communicates with engine and starts/manages the VMs on 
the host on behalf of engine.
oVirt node: is a special slimmed down Fedora distro that includes VDSM 
and a small setup so that it can be used as a oVirt host


People tend to mix and match ovirt-host and ovirt-node which makes for 
nice communication problems :-)


If you haven't done so, there is an irc channel, ovirt, on irc.oftc.net 
with helpful people, if they are awake.

maybe wikify the above?
It is in the wiki. Only problem is some people used a other method and I 
only showed that following the instructions at the Download page works 
for me. Its a little more detailed and slightly adapted to our env but 
in essence its:

install Centos (either minimal or full)
install epel repo
install ovirt repo
install ovirt-engine-setup
run engine-setup

http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/ is the

The proxmox site/forum has a wiki page describing which folder belongs

Search for virtio-win, I think.

Re: [Users] oVirt 3.3/F19 - Windows guest unable to access network

Hi,

I'm having network issues with a Windows Server 2008 R2 guest running 
on an F19 host. The guest has a static configuration and is able to 
ping itself and the host it is running on, however cannot ping the 
gateway, any other hosts on the local network, or external hosts. A 
RHEL 6.4 guest on the same host with a similar static configuration 
works normally.


Iptables/firewalld on the host are switched off and the network 
definitions in the XML for each VM (Windows/RHEL) are the same. The 
virtio network drivers are installed in the guest. The guest was 
created from a Win 2008 R2 template, which was created from a VM 
imported from oVirt 3.2. Software versions below.


Just to be sure, iptables/firewalld!=Windows Firewall. Is there a rule 
in the windows firewall to allow ping or is it disabled?


Are there any manual configuration steps required on the host to 
support Windows guests? Are there any particular diagnostic steps I 
could take to try and narrow down the cause?


Don't think so, just converted a Windows2008R2 datacenter guest from 
Vmware to oVirt and it ran, after adding virtio drivers or using e1000 
and/or ide disks.



Versions:

-oVirt 3.3.0-4

-F19 3.10.11-200

-QEMU 1.4.2-9

-Libvirt 1.1.2-1

-VDSM 4.12.1-2

-virtio-win 0.1-52


Your problem looks like the problem René had with his Solaris guest, its 
a recent thread. Turned out that setting -cpu Nehalem by ovirt caused 
networking in the Solaris guest to fail.
Don't think this is your problem though since lots of people run Windows 
guest without problems.

[Users] Ovirt guest agent for 3.2 el6

Is it possible to add an ovirt-guest-agent-1.0.8-el6.rpm to the ovirt 
3.2 repository?
I'm asking because I tried the ovirt-guest-agent installation on a VM by 
slightly modifying the repo file to point to the 3.3 directory and the

I had to relax this to 666 to enable the VMs to start

Yes, me.

Any hint about what may have caused this odd problem?


yum update.

I updated one of my hosts and after that that host couldn't start VMs 
anymore with exact the same errors. See thread 'Starting VM error' by 
Shaun Glass. I tried a couple of things but not making world readable 
those files. Will probably restore a backup and try it.
I added the virt-preview repo for F18 and updated qemu/libvirt which 
also solved the problem.
The difference between the updated and not updated host were really 
minimal. See the thead for logs.

This isn't about provisioning with Foreman. Its about having the compute
nodes NOT having any spinning disks. So the only way to start a node is
to pxeboot it and then let it (re)connect with the engine. Then it will
be identified by engine as either a new node or a reconnecting node and
it will get its configuration from the engine. For reference: thats how
VirtualIron works. It has a managment network, just like ovirt, and on
that it runs a tftp and dhcp server. Nodes are plugged into the
managment network, without disk, and then pxe booted after which they
appear in the webui as new unconfigured nodes. You then can set various
settings and upon rebooting the nodes will recieve these settings
because it is recognised by its mac address. The advantage of this
construct is that you can place a new server into a rack, cable it,
power on and go back to you office where you'll find the new node
waiting to be configured. No messing around with CDs to install an OS,
not being in the datacenter for hours on end, just in and out.

Yes, disks are cheap but they brake down, need maintenance, means
downtime and in general more admin time then when you don't have them. (
its a shame to have a raid1 of 2 1Tb disk just to install an OS of less
then 10G)


just wondering, how do they prevent a rogue node/guest from 
masquerading as such a host, getting access/secrets/VMs to be launched 
on such an untrusted node (they could easily report a different mac 
address if the layer 2 isn't hardened against that)?


They would need physical access to your rack which ofcourse is locked, 
you would need to powerdown/up which would trigger an alert, switch port 
down/up would trigger an alert, so probably you're notified that 
something not quite right is happening.  I haven't gone through the 
source to see if there is more then just the mac address check.


other than that, yes. we actually used to have this via the 
AutoApprovePatterns config option, which would have the engine approve 
a pending node as it registers (I admit i don't think anyone used this 
last several years, and it may be totally broken by now).


please note this doesn't solve the need for a disk, just the 
auto-registration part (if it still works)
What I would like is to have the ovirt Node pxe booting and getting its 
config from engine or autoregister. I know there is a script which 
converts the iso into a huge pxeboot kernel but don't know how to solve 
or if its solved the config part.


@karli:
If you run your cluster in Memory Optimization=None then you won't need 
swap. Have been doing that for years and haven't had a single problem 
attributed to that. I just would like to have the choice, pxe boot the 
node and know that you don't have swap. Run with disks if you really 
need overprovisioning.

Swap-file over NFS must suck quite badly, no? We have bought

I don't quite see the point, unless you have mirrored ssd's. Data 
corruption on ssd's is more frequent than on spinning disks and 
disastrous when it happens in a swapped out page... (And why not add 
more RAM?)


But why use swap at all? I'm assuming you dimension a node to its 
intended use, so I guess lots of memory and CPU cores (in our case 
anyway) and you can allocate the available memory to the VMs until it's 
finished. I don't see much need for swap there.


Perhaps my view is different than usual, I see swap as the gravelly 
escape roads on steep hills for trucks/cars who have failing breaks. It 
just reduces the damage in case of unexpected failures. Swap isn't 
something to use on a regular basis as cheep memory, as RAM is not that 
expensive anymore and magnitudes faster.

I'd like these VMs to "repel" each other w.r.t. the physical running

I'm sure this is all scriptable, but it seems to fit with the management

Because of discussion on IRC I'll make a RFE for the following:
When you have lots (>25) ISCSI LUN's where your ovirt hosts have

is no apparent sorting on LUN ids or a searching possibility on part
of the id. Scanning by eye of such a list is getting very boring and
error prone.

Add Virtual Disk/External (Direct LUN), would be nice if the column

[Users] Engine-config -s small problem

[noc]

Hi All,

Don't know if this is documented somewhere but I ran into an interesting 
problem yesterday. First we had intermittent problems with ssh 
connecting to VMs which we traced to having two oVirt installation being 
active in one subnet. Found the post from January where it is explained 
how engine allocates its mac address pool and how to set it with 
engine-config -s MacPoolRanges. Today I remembered that I had done that 
when I was about to start a VM and removed the nic from the VM and added 
it back. To my surprise it got the same macaddress as it had (from the 
old range). On a hunch I restarted ovirt-engine and redid the remove/add 
operation and now it got a new mac address from the range specified.
Shouldn't the engine be aware that the config is changed if you use 
engine-config and reload its cached values from the database?

I expected this but it seems not to be the case, bug or by design.

It looks like after image upload, virt-v2v ties to connect to 
libvirtd. The vdsm@rhevh login with shibboleth password doesn't work. 
The oVirt is installed on Fedora 18. Engine and vdsmd runs on the same 
host. Is there any difference between authentication to libvirt on 
oVirt 3.0 and oVirt 3.2? Could I ask you for help with this problem?



Try vdsm@ovirt with the same password.

Hi Alon,

On 03/19/2013 07:56 AM, Alon Bar-Lev wrote:

Obviously something is wrong with the dependency, not sure which
version of gluster is required and what is available in fedora.

The root cause of this is that setup defaults no to use both
gluster and virt for the default domain, while in the past it used
to default to virt. So if you do not wish to use gluster, please
do not select both at installation, or turn of the gluster from
the cluster after installation.

I think the wording here is confusing.

To an oVirt user, "using Gluster" means having a Gluster storage
domain
as shared storage.

In the context of the Gluster management console, oVirt does not use
Gluster, Gluster uses oVirt.

Would it be possible to review the set-up process to ensure that we
are
not inadvertently sending users who just want to use a stable version
of
Gluster as storage in the wrong direction? This comes up frequently,
and
seems to be confusing people.

Thanks,
Dave.

Now I am confused
Do you or don't you need vdsm-gluster on your system?
If the gluster checkbox is set on the cluster then you'll need the 
gluster packages. If you don't use gluster but said so 
(both=virt+gluster) during engine-setup then the checkbox will be 
checked and you'll need the packages.
The bigger problem ofcourse is that oVirt-3.2.1 requires gluster-3.4.0 
which isn't in the standard repos at the moment.

Running the commands in a shell indeed gives the errors shown.

I have a wild guess but what interface is -I default referring to?
I had more than one interface activated for this host but moved it to a 
cluster which didn't have the network definitions and removed the now 
invalid networks from the host. Just checked with tcpdump and the 
traffic is going through ovirtmgmt interface and the storage is responding.
/var/lib/iscsi isn't filled with info, only 
sendtargets/target_ip_address/st_config

But now i have the following error when i tried to start glusterd:

There's no systemd init script  for gluster, but there's a script in 
/etc/init.d . Is that the cause of problem? It's the package somehow 
broken?


What can i do now to fix and start glusterfs in order to test again?


check your owner:group on the gluster folders, they should be 36:36. You 
can achieve this by using the 'optimize' button in the webui while 
looking at the Volume.

How??

I tried adding this repo but but yum says that there are no updates

My yumfoo isn't that good so I don't know how to force it. Besides I

Re: [Users] Installing a lab setup from scratch using F18

[noc]

Sorry for the late reply, see comments inline.


2013-1-22 2:11, Joop:
As promised on IRC (jvandewege) I'll post my findings of setting up 
an ovirt lab environment from scratch using F18.

First some background:
- 2 hosts for testing storage cluster with replicated gluster data 
and iso domains (HP ML110 G5)

gluster data or cluster data?

Gluster



- 2 hosts for VMs (HP DL360 G5?)
- 1 managment server (HP ML110 G5)
All physical servers have atleast 1Gb connection and they also have 2 
10Gb ethernet ports connected to two Arista switches.
Complete setup (except for the managment srv) is redundant. Using 
F18-x64 DVD and using minimal server with extra tools, after install 
the ovirt.repo and the beta gluster repo is activated.

This serves as a proof of concept for a bigger setup.

Problems sofar:
- looks like F18 uses a different path to access video since using 
the defaults leads to garbled video, need to use nomodeset as a 
kernel option
Do you mean the VDSM host installed with F18 or the guest in the host 
with FC 18 here? I suppose you don't have much chance to access the 
graphics screen of the VDSM host.

Talking about the hosts.


- upgrading the minimal install (yum upgrade) gives me 
kernel-3.7.2-204 and the boot process halts with soft locks on 
different cpus, reverting to 3.6.10-4.fc18.x86_64 fixes that. 
Managment is using 3.7.2 kernel without problems BUT it doesn't use 
libvirt/qemu-kvm/vdsm, my guess its related.
- need to disable NetworkManager and enable network (and ifcfg-xxx) 
to get network going
- adding the storage hosts from de webui works but after reboot vdsm 
is not starting, reason seems to be that network isn't initialised 
until after all interfaces are done with their dhcp requests. There 
are 4 interfaces which use dhcp, setting those to bootprotocol=none 
seems the help.
Usually, I use the static IP for each server because the engine add 
the VDSM host by IPs.
I set a static address too but still NetworkManager runs and tries to do 
its best.
The DL360 machines run 3.7.2 without problems BUT they don't run the 
latest gluster-3.4, that might be the difference or else they are immune 
for this specific problem between 3.7.2 and ML110 hardware.




- during deploy their is a warning about 'cannot set tuned profile', 
seems harmless but hadn't seen that one until now.
- the deployment script discovers during deployment that the ID of 
the second storage server is identical to the first one and abort the 
deployment (Blame HP!) shouldn't it generate a unique one using 
uuidgen??



Host deployment went OK but for one thing and that the storage domain 
wouldn't attach. Putting the host in maintenance mode and activating did 
not help. It turnes out there are two problem of which one is already 
solved:

- ntpd/chronyc SOLVED thanks to Gianluca
- host needs to have SELinux set to Permissive and then attach storage 
domain works.
- on the managment host I still need NFSv3 settings in/etc/nfsmount.conf 
or else iso-upload doesn't work




Things that are OK sofar:
- ovirt-engine setup (no problems with postgresql)
- creating/activating gluster volumes (no more deadlocks)

Adding virt hosts has to wait til tomorrow, got problems getting the 
dvd iso onto an usb stick, will probably burn a DVD to keep going.
Migration works OK, powermanagment through ipmilan/ilo2 works, 
export/import VMs, v2v test from esxi to ovirt, all OK ;-)



Setting up a storage network still needs to be tested

[Users] Different Clusters for virt-hosts and storage-hosts

[noc]

Hi All,

I'm trying out ovirt-nightly and would like to split my virtualisation 
hosts from my storage hosts. So I setup a second cluster (Storage) which 
will only do gluster storage, added two hosts to it, added two volumes 
to it (gluster-data, gluster-iso) and added a master Data domain 
(GlusterData) and an iso domain (GlusterIso). The storagetype is posixFS 
and creating a disk is no problem but for one thing. When it has 
finished I can't see it in the interface but it exists on disk and can 
be selected when a VM is created.

Now for the real test ;-)
If I add a host to the default cluster it will display an error and end 
up Non Operational because it can't connect to the storage (Failed to 
connect Host host01 to the Storage Domains GlusterData). From vdsm.log I 
see that it tries to mount but it fails:
Thread-20::DEBUG::2013-01-09 
14:19:01,792::misc::84::Storage.Misc.excCmd::() '/bin/sudo -n 
/bin/mount -t glusterfs st01.nieuwland.nl:/gluster-data 
/rhev/data-center/mnt/st01.nieuwland.nl:_gluster-data' (cwd None)
Thread-20::ERROR::2013-01-09 
14:19:01,933::hsm::2212::Storage.HSM::(connectStorageServer) Could not 
connect to storageServer


Running the mount command by hand and mounting it to /mnt works OK.
Problem seems to be that ../mnt/st01.nieuwland.nl:_gluster-data doesn't 
exist.


I'm doing something wrong and can't this not work because I'm not 
understanding how clusters are supposed to work or should this work?


I switched to posixfs because I have similar problems when using NFS but 
then between the two storage host when they are also virtualistation hosts.


This is test install so I can rebuild anything you want/need, I have the 
logs from a clean install until now.

Just saw the question what route to follow for post 3.2 and picked up 
something that I didn't know about was going to ask if it was 
possible to implement, namely setting permissions on the volume 
folder when creating a gluster volume.
But when trying it out I found a little snag. I installed two hosts 
with a minimal fed17 install, added a couple of repos to enable 
installing the latest nightlies (it needed a later then 0.9 libvirt 
(0.10 from danken) and qemu-kvm and since a couple of days a later 
gluster which outputs in xml (gluster-3.4..)

Steps:
- start with a clean engine-setup
- in the webui, set the cluster to 3.2 and virt+gluster, set the DC 
to 3.2/NFS

- add the two hosts, went OK.
- add a Volume, gluster-data, gets created OK, BUT the Create Volume 
'popup window' never stops spinning its busy cursor :-(
Looking at the logs I see that the volume is created, st01 is used, 
st02 gets the message, creation is returning Succes but it looks like 
the global lock is never released.
We have an issue with locking while creating a volume, fix for this is 
currently under review.

http://gerrit.ovirt.org/10448
I still might have the vdsm logs or else I can replay it to generate 
them, but if it really is this issue then it they might not be needed.

Is the workaround I used a viable one? (restarting ovirt-engine)
