[ovirt-users] oVirt nodes not responding

2019-11-27 Thread Tim Herrmann
Hi everyone,

we have an oVirt-Cluster with 5 nodes and 3 of them provide the storage
with GlusterFS and replica 3.
The cluster is running 87 VMs and has 9TB storage where 4TB is in use.
The version of the oVirt-Engine is 4.1.8.2 and GlusterFS is 3.8.15.
The servers are running in a HP bladecenter and are connected with 10GBit
to each other.

Actually we have some problems that all ovirt nodes periodically won't
respond in the cluster with the following error messages in the oVirt
webinterface:

VDSM glustervirt05 command GetGlusterVolumeHealInfoVDS failed: Message
timeout which can be caused by communication issues
Host glustervirt05 is not responding. It will stay in Connecting state for
a grace period of 68 seconds and after that an attempt to fence the host
will be issued.
Host glustervirt05 does not enforce SELinux. Current status: PERMISSIVE
Executing power management status on Host glustervirt05 using Proxy Host
glustervirt02 and Fence Agent ilo4:xxx.xxx.xxx.xxx.
Manually synced the storage devices from host glustervirt05
Status of host glustervirt05 was set to Up.


In the vdsm logfile I can find the following message:
2019-11-26 11:18:22,909+0100 WARN  (vdsm.Scheduler) [Executor] Worker
blocked:  timeout=60, duration=180
at 0x316a6d0> task#=2859802 at 0x1b70dd0> (executor:351)


And I figured out, that the gluster heal info command takes very long:
[root@glustervirt01 ~]# time gluster volume heal data info
Brick glustervirt01:/gluster/data/brick1
Status: Connected
Number of entries: 0

Brick glustervirt02:/gluster/data/brick1
Status: Connected
Number of entries: 0

Brick glustervirt03:/gluster/data/brick2
Status: Connected
Number of entries: 0


real 3m3.626s
user 0m0.593s
sys 0m0.559s


A strange behavier is also that there is one virtual machine (a postgresql
database) which stops running unexpectedly every one or two days ...
The only thing that has been changed on the vm in the least past was a
resize of the disk.
VM replication-zabbix is down with error. Exit message: Lost connection
with qemu process.

And when we add or delete a larger disk with approximately 100GB in
glusterfs, the glusterfs cluster freaks out won't respond anymore.
This also results in paused VMs ...


Has anyone an idea what could cause such problems?

Hello Tal

It seems you have a very big overkill on your environment. I would say that
normally 2 x 10Gb interfaces can do A LOT for nodes with proper redundancy.
Just creating Vlans you can separate traffic and apply, if necessary, QoS
per Vlan to guarantee which one is more priority.

If you have 2 x 10Gb in a LACP 802.3ad Aggregation in theory you can do
20Gbps of aggregated traffic. If you have 10Gb of constant storage traffic
it is already huge, so I normally consider that Storage will not go over a
few Gbps and VMs another few Gb which fit perfectly within even 10Gb

The only exception I would make is if you have a very intensive (and I am
not talking about IOPS, but throughput) from your storage then may be worth
to have 2 x 10Gb for Storage and 2 x 10Gb for all other networks
(Managment, VMs Traffic, Migration(with cap on traffic), etc).

I'm not sure how you'd get more throughout than you can get in a single
physical link. You will get redundancy.

Of course, on the storage side you might benefit from multiple bonded
interfaces.

[ovirt-users] Ovirt nodes NFS connection

2018-03-21 Thread Tal Bar-Or
Hello All,

I am about to deploy a new Ovirt platform, the platform  will consist 4
Ovirt nodes including management, all servers nodes and storage will have
the following config:

*nodes server*
4x10G ports network cards
2x10G will be used for VM network.
2x10G will be used for storage connection
2x1Ge 1xGe for nodes management


*Storage *4x10G ports network cards
3 x10G for NFS storage mount Ovirt nodes

Now given above network configuration layout, what is best practices in
terms of nodes for storage NFS connection, throughput and path resilience
suggested to use
First option each node 2x 10G lacp and on storage side 3x10G lacp?

The second option creates 3 VLAN's assign each node on that 3 VLAN's across
2 nic, and on storage, side assigns 3 nice across 3 VLANs?
Thanks

Re: [ovirt-users] oVirt Nodes Monitoring

2017-03-08 Thread Anantha Raghava

Hi,

You can also monitor by enabling SNMP in Hosts. For this purpose, using 
the MIB, you need to build a Zabbix Template as detailed in the link 
here https://github.com/jensdepuydt/zabbix-ovirt


We are monitoring Version Hosts with CentOS 7 and oVirt 4.0.x using this 
method.


I will share the Zabbix-Template, we have built tomorrow as I, at the 
moment do not have access to my resources.

Just for others benefit just adding the repository and installing the 
agent won't work. Need to add it to SELINUX. For that I used the

What would be the best way to install its zabbix-agent package and

It's currently probably the best tested and most stable platform when

RHEL / CentOS 7 Are currently recommended, amongst others for Ovirt4.

  You're getting the packages from ovirt's repository not the distro base
so no need to worry that one distro or another is behind which would most
likely be the case if you were getting base packages.

Hello,

I was testing  Ovirt inside a VDI proyect.
Now, I know there is new version of Ovrit (4.X) and VDI Software so I have 
decided to remake the installation of all.

I wonder which is the best OS platafform for the Host (Ovirt - Nodes). (Fedora 
/ Red Hat Enterprise Linux / CentOS) Now I have CentOS 7 64Bit but... I am not 
sure.

What do you think about it? Fedora or CentOS?
Which version? Fedora 19? Fedora 24? CentOS 6? CentOS 7?

I always had the feeling that Fedora is a little ahead against CentOS for 
example oVirt packages.

Thank  you

Hello,

 official numbers would also be interesting to me.
I can tell you that we do have some larger infrastructures running
on several engine hosts, one of them for example has 3 datacenters,
7 cluster, 200 hosts. We do have noticeable performance issues on
the engine host. The engine is already running on rather performant
hardware including 12 cores and SSDs - but nevertheless we have load
averages >20 on it and very slow response time from the engine
itself.

[ovirt-users] Ovirt nodes lose up status

2014-07-23 Thread Fabien CARRE
Hello,
I am experiencing an issue with on my current ovirt DC.
The setup is 2 machines running Ovit Nodes connected to a LaCie 12big Rack
Fibre 8, the nodes are connected to both controllers.. This configuration
has worked fine for a couple of weeks.

Recently the nodes go from Up status to Non Operational. When I activate
them back they don't last more than 2 minutes.

Hello,
I am experiencing an issue with on my current ovirt DC.
The setup is 2 machines running Ovit Nodes connected to a LaCie 12big

Recently the nodes go from Up status to Non Operational. When I 
activate them back they don't last more than 2 minutes.



/var/logl/messages on both nodes shows the same errors :
