[Users] general (totally noob) questions...

[Michael Hauber]

While I am not completely new to running instances in KVM/Qemu, I am a total 
noob when it comes to clustering.

While I realize that not all of these questions pertain specifically to the 
oVirt project, I would much rather get input from people that have experience 
in this environment.

I am in the process of designing my next server farm and would like to know 
some basics that I can't seem to find the answers to via google search.


Background:

I have a server farm setup for a large family.  It consists of 9 servers 
(minimal-to-medium loads for the most part, but they are in poor condition 
physically).  My hopes are to run this same setup virtually in a 3-node 
cluster.  I can run the entire farm in a virtual environment on a host with a 
dual, quad-core box with 64gig RAM.  That said, I know that each of these 
nodes will be capable of handling the entire load by itself if absolutely 
necessary.

For disk space, my hopes are to use two drive arrays (10 configuration?) which 
I can build (up and out) from without having too much trouble.

Everything will be fiber, including drops to the computers and televisions.  
Copper will exist as well for things like POE, printers, etc. (but not in 
scope)


Questions:

1.  As I understand it, a N-to-N configuration means that there will be load 
balancing between the nodes as well as failover.  Is the load balancing 
something that is manual (I have to monitor/balance the load manually, or is 
it done automatically?)  

2.  If it is done automatically, how do the loads get split up?  Is the 
virtual machine itself the unit of load that transfers from one node to 
another or does it go so far as balancing services running inside those 
virtual machines?

3.  For the fail-over, is it seemless in the sense that the user's connections 
don't get reset or is there a short period of down-time before the service is 
available again?  While this isn't a big issue for me, it is something that 
I've been wondering about.

4.  Fibre channel or FCOE?  (I've spent entire evenings trying to get a 
straight answer through google searches, but there seem to be way too many 
agendas).  Being that one of the virtual servers will be a media server for 
the televisions (new addition), my worry is lag-time (I would like to serve at 
least 5 televisions without lag-time).  The array will also support things 
like file server, space for about 2-dozen www (family pages (lots of 
pictures)), space for mail, space for backups (rSync,Amanda), ISO boots, etc.

I have the logical and physical topology drawn up for the most part, but until 
I understand a bit more, I'm scared _less about dropping any money into the 
project because I've neither seen a setup like this in action, and what I find 
online seems a bit vague in the way of details (dumbed-down enough for the 
likes of me to know if the hardware I'm buying is necessary and/or sufficient 
to 
achieve my goals).

Any and all pointers, suggestions, patience, etc. would be greatly 
appreciated.

I believe that the gluster nfs server only supports tcp. On my setup, 
I've edited /etc/nfsmount.conf with Defaultvers=3, Nfsvers=3, and 
Defaultproto=tcp

I notice that in your previous message, citing the mount that
didn't work, you were mounting :/export, and above you're mounting
:/data. Can you also mount the export volume from another computer?



So volumes work but I get a 500 error timeout when trying to
add as a
storage domain in ovirt.  weird?

Hi,

@Dave,
Don't know if you have the luxury of starting from scratch but to be 
honest I have had problem with multple engin-setup/cleanup cycles and 
had to start from scratch which was faster than figuring out what went 
wrong. Those problems where with the pre-3.1 release. This is my 
ovirt.repo which I guess will be same for you:


[ovirt-stable]
name=Stable builds of the oVirt project
baseurl=http://ovirt.org/releases/stable/rpm/Fedora/$releasever/
enabled=1
skip_if_unavailable=1
gpgcheck=0

[ovirt-beta]
name=Beta builds of the oVirt project
baseurl=http://ovirt.org/releases/beta/rpm/Fedora/$releasever/
enabled=1
skip_if_unavailable=1
gpgcheck=0

[ovirt-nightly]
name=Nightly builds of the oVirt project
baseurl=http://ovirt.org/releases/nightly/rpm/Fedora/$releasever/
enabled=0
skip_if_unavailable=1
gpgcheck=0


And the following is the first part of my history of my managment server

   1  chkconfig sshd on
   2  service sshd start
   3  ifconfig
   4  yum update --exclude=kernel*
   5  uname -a
   6  yum install -y firefox
   7  yum install -y wget
   8  yum install -y mc
   9  yum install -y spice-xpi
  10  init 6
  11  system-config-network
  12  cd /etc/sysconfig/networking/
  13  ls
  14  ls -l devices/
  15  cat devices/ifcfg-em1
  16  nano devices/ifcfg-em1
  17  nano devices/ifcfg-p2p1
  18  nano devices/ifcfg-p2p2
  19  ls
  20  ls devices/
  21  chkconfig NetworkManager off
  22  service NetworkManager stop
  23  chkconfig network on
  24  service network start
  25  ifconfig
  26  init 6
  27  exit
  28  ifconfig
  29  ifconfig
  30  yum localinstall 
http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm

  31  nano /etc/yum.repos.d/ovirt.repo
  32  yum install engine-setup -y
  33  ifconfig
  34  ifconfig
  35  pwd
  36  system-config-network
  37  ifconfig
  38  service network restart
  39  ifconfig
  40  init 6
  41  exit
  42  cat /proc/cpuinfo
  43  dmesg | grep CZ100
  44  yum install dmidecode
  45  cat /proc/meminfo
  46  dmidecode | less
  47  dmidecode | grep CZ
  48  ps
  49  ps -ef
  50  top
  51  cat /etc/exports
  52  nano /etc/exports


So all I did was follow the quick install and started of by getting some 
things installed I like, stop NetworkManager en setup the network, 
installed the ovirt.repo, entered my server in RT ;-) (dmidecode stuff) 
and not shown because I probably did it in another console engine-setup.
Both my engine server and the two hosts I run for testing are HP 
Proliant ML110 and one DL3xx host. I had one migration problem because 
the uuid in the ML110's is the same and then you can't migrate, error 
is: migrating to same host, or something close to it.

Base install is from Fedora 17 KDE live CD.

What is the OS you run ovirt-engine on?



I'm going to take a stab and guess Fedora. This came up for an unrelated reason 
in #fedora-devel the other day, because Fedora (and I suspect Debian as well) 
has a policy of sticking as close to upstream as possible it uses the shmmax of 
the upstream kernel - which is as you note quite low. In RHEL and other EL6 
derivatives this value is modified and set much higher.

Steve

  
OK, learned something because I didn't suspect that Fedora would be so 
low because its set higher in RHEL en for example CentOS that I use on a 
db production platform.

Thought that Fedora and RHEL were much closer.

Nic, how did you make out with this?  I'm looking to do the same thing and
am wondering if there is any risk in running the engine on a VM managed by
the same engine, as you were suggesting before.  Did you give this a shot?

Itamar, why did you steer Nic away from this?

I increased the kernel's SHMMAX, and engine-cleanup worked correctly.

Postgres. It seems that either the package maintainer is very
conservative or postgres itself is. Standard on the Debian 6 server was

When I re-run engine-setup, I also got stuck when reconfiguring NFS -
when engine-setup asked me if I wanted to configure the NFS domain, I
said "yes", but then it refused to accept my input of "/mnt/iso" since
it was already in /etc/exports - perhaps engine-cleanup should also
remove ISO shares managed by ovirt-engine, or else handle more
gracefully when someone enters an existing export? The only fix I
found was to interrupt and restart the engine set-up.


Just switch to a different terminal and edit /etc/exports and continue
engine-setup.


Also, I have no idea whether allowing oVirt to manage iptables will
keep any extra rules I have added (specifically for DNS services on
port 53 UDP) which I added to the iptables config. I didn't take the
risk of allowing it to reconfigure iptables the second time.

After all that, I got an error when starting the JBoss service:


Starting JBoss Service... [ ERROR ]

Please check log file
/var/log/ovirt-engine/engine-setup_2012_09_21_14_28_11.log for more

And when I checked that log file:

And when I check the system journal, we're back to the service starts,

Any pointers into how I might debug this issue? I haven't found
anything similar in a troubleshooting page, so perhaps it's not a
common error?

Are you following the setup instructions from  the Wiki?
I have done that a couple of times now and haven't had problems sofar.
Had lots of problems with the pre-3.1 releases though.

 It physically is not there. (My fault I know)  Is there a way that

Fell free to try the below script (not part of official project) for 
brute force:


(from the engine side)
# yum install python-psycopg2 -y

I noticed something.  If I am trying to mount the gluster share from

No there is an active host in the cluster.  It still will not allow removal

Is it the only host in the DC, if that's the case you can't put it to 
maintenance mode.

I'm going to take a stab and guess Fedora. This came up for an unrelated reason 
in #fedora-devel the other day, because Fedora (and I suspect Debian as well) 
has a policy of sticking as close to upstream as possible it uses the shmmax of 
the upstream kernel - which is as you note quite low. In RHEL and other EL6 
derivatives this value is modified and set much higher.

Hi,

I have done that a couple of times now and haven't had problems sofar.
Had lots of problems with the pre-3.1 releases though.


I am installing RPMs on Fedora 17 through the 
http://ovirt.org/releases/stable/rpm/Fedora/$releasever/ repository.


I've been following the quick start guide: 
http://wiki.ovirt.org/wiki/Quick_Start_Guide and have been noting my

Is there a better document to follow?

I can mount to another computer with this command:

mount -o mountproto=tcp,vers=3 -t nfs gfs1.bostonvineyard.org:/data
/home/administrator/test

So volumes work but I get a 500 error timeout when trying to add as a

Re: [Users] Problem with creating a glusterfs volume

[Dominic Kaiser]

Hey All,

So I finally found the problem.  Cheap NIC's.  Installed Intel NIC's no
problems creating gluster volumes and distributed replicated ones.
 Broadcom and Realtek yuk!  So now I am trying to mount the gluster volume
as a nfs mount and am having a problem.  It is timing out like it is
blocked by a firewall.

I am trying to:  mount -t nfs gfs1.bostonvineyard.org:/export
/home/administrator/test

Here is gfs1 tail vdsm.log

Do you know why I can not connect via NFS?  Using an older kernel not 3.5
and iptables are off.

I increased the kernel's SHMMAX, and engine-cleanup worked correctly.

Has anyone else experienced this issue?
Yes, not related to oVirt but on a database server also running 
Postgres. It seems that either the package maintainer is very 
conservative or postgres itself is. Standard on the Debian 6 server was 
also very low shmmax.

What is the OS you run ovirt-engine on?




When I re-run engine-setup, I also got stuck when reconfiguring NFS - 
when engine-setup asked me if I wanted to configure the NFS domain, I 
said "yes", but then it refused to accept my input of "/mnt/iso" since 
it was already in /etc/exports - perhaps engine-cleanup should also 
remove ISO shares managed by ovirt-engine, or else handle more 
gracefully when someone enters an existing export? The only fix I 
found was to interrupt and restart the engine set-up.


Just switch to a different terminal and edit /etc/exports and continue 
engine-setup.


Also, I have no idea whether allowing oVirt to manage iptables will 
keep any extra rules I have added (specifically for DNS services on 
port 53 UDP) which I added to the iptables config. I didn't take the 
risk of allowing it to reconfigure iptables the second time.


After all that, I got an error when starting the JBoss service:


Starting JBoss Service... [ ERROR ]

Please check log file 
/var/log/ovirt-engine/engine-setup_2012_09_21_14_28_11.log for more

And when I checked that log file:

Any pointers into how I might debug this issue? I haven't found 
anything similar in a troubleshooting page, so perhaps it's not a 
common error?


Cheers,
Dave.






Are you following the setup instructions from  the Wiki?
I have done that a couple of times now and haven't had problems sofar. 
Had lots of problems with the pre-3.1 releases though.

[Users] Installation problem

[Dave Neary]

Hi all,

I was working through the installation of ovirt-engine today (after 
spending more time than I care to admit struggling with networking & DNS 
issues - VPNs, dnsmasq, "classic" network start-up and iptables/firewall 
rules can interract with each other in strange and surprising ways).


Anyway - I went through the engine set-up successfully, and got the 
expected message at the end: " Installation completed successfully 
**" with a message to visit the engine web application to finish set-up.


Unfortunately, when I connected (after resolving networking issues) to 
the server in question, I got a "Service temporarily unavailable" error 
(503) from Apache.


in httpd's error.log, I have:

 [Fri Sep 21 13:37:03 2012] [error] (111)Connection refused: proxy: AJP: 
attempt to connect to 127.0.0.1:8009 (localhost) failed

for (localhost)
 [Fri Sep 21 13:37:03 2012] [error] proxy: AJP: failed to make connection to 
backend: localhost




When I try to restart the ovirt-engine service, I get the following in 
journalctl:

 Sep 21 13:34:44 clare.neary.home engine-service.py[5172]: The engine PID file 
"/var/run/ovirt-engine.pid" already exists.

/var/run/ovirt-engine.pid does not exist.
 Sep 21 13:34:44 clare.neary.home systemd[1]: Unit ovirt-engine.service entered 
failed state.




I tried to clean up and restart, but engine-cleanup failed:

[root@clare ovirt-engine]# engine-cleanup -u

Stopping JBoss service...[ DONE ]

Error: Couldn't connect to the database server.Check that connection is working 
and rerun the cleanup utility
Error: Cleanup failed.
please check log at /var/log/ovirt-engine/engine-cleanup_2012_09_21_14_02_37.log




It turns out, in /var/log/messages, that I have these error messages:

Re: [Users] non-operational state as host does not meet clusters' minimu CPU level.

[wujieke]

currently, I create a cluster with Conroe family. My host/node works. And I
can create some VMs on it.
But I am not sure if the issue talking here will impact the VM's
performance? Or stability ?

ok, so libvirt/virsh detect sandybridge, but vdsm only reports conroe.
there used to be a bug around this in vdsm - which version of vdsm are you
running?

I'm surprised this wasn't caught earlier.  I've submitted a patch to add
the port to the default firewall [1].  

You can run the following command to open the firewall port manually on
ovirt-node.  

python -c 'from ovirtnode.ovirtfunctions import *; 
manage_firewall_port("16514","open","tcp")'

To make it work across reboots, do the following:

 1. Press F2 on the TUI to get a shell
 2. scp the attached patch file to /tmp on ovirt-node (you need to
initiate this from ovirt-node, not from your local machine)
 3. on ovirt-node, run # mount -o remount,rw /
 4. cd /usr/libexec
 5. patch http://gerrit.ovirt.org/8116

So I figured, I could use our Eaton/Raritan metered pdus to allow fencing
the designated SPM nodes but than realized that controlling pdus by snmp
was not supported by oVirt. Any chance that is going to change? Or can you
point me to the Java class where I can add this?

Kind regards,

ok, so libvirt/virsh detect sandybridge, but vdsm only reports conroe.
there used to be a bug around this in vdsm - which version of vdsm are you
running?

 I am trying to install the ovirt on my Xeon E5-2650 process on Dell 
 server, which is installed with Fedora 17. While I create a new 
 host , which actually is the same server as overt-engine is running.

 The host is created ,and starting to "installing". But it ends with 
 "Non operational state".

 Error:

 Host CPU type is not compatible with cluster properties, missing 
 CPU

 But in my cluster, I select "sandybridge" CPU, and my Xeon C5 is 
 also in Sandy bridge family.  And also this error lead my server
reboot.

 Any help is appreciated.

 Btw: I have enable INTEL-VT in BIOS. And modprobe KVM and kvm-intel 
 modules. . attached is screen shot for error.
