Re: [ovirt-users] Shrink gluster logical volume under Ovirt 4.0

[Sahina Bose]

Are you shrinking the gluster volume by removing bricks, or are you
shrinking the underlying LV/filesystem of the bricks associated with
gluster volume?
If latter, you need to move storage domain to maintenance and umount from
all hosts.

Re: [ovirt-users] oVirt backup and VM pauses.

[Maton, Brett]

I noticed similar behavior, I think if the memory state isn't backed-up
then the machines won't be paused.
Not seen an option in script to 'flip' the flag, but then again I haven't
looked at the script in enough detail to see what needs changing.

[ovirt-users] oVirt backup and VM pauses.

[Misak Khachatryan]

Hello,

I'm using oVirt and recently added backup functionality using this script:

https://github.com/wefixit-AT/oVirtBackup

This script runs every day from cron, but i noticed very bad behavior
with the machines. Script on some stage pauses them, and it leads to
problems. I have NTP stratum 2 server as a virtual machine, which I
added to pool.ntp.org. When machine pauses, it loses time sync for a
while and NTP.ORG monitoring system removes this machine from pool.
And it take about a 24 hours to get good score to be included int the
pool again, then next backup time arrives, and so on.

So my question is - any suggestion to prevent this behavior or any
other backup solution without pausing available?

Best regards,
Misak Khachatryan

[ovirt-users] Shrink gluster logical volume under Ovirt 4.0

[Ian Neilsen]

Hi all

I need to shrink/reduce the size of a gluster logical volume under Ovirt
4.0.

Is there anything I should be aware of before reducing the file system and
logical volume on my servers?

I ask because I see under "df -h" the following;
192.168.3.10:data   5.7T  3.4G  5.7T   1%
/rhev/data-center/mnt/glusterSD/192.168.3.10:data

The storage domain is not connected yet via oVirt manager, well at least it
isnt showing. Im running in hosted mode converged.


Thanks in advance

Version 4.1 of the SDK isn't very different for version 4.0. It is very
different from version 3.6.

Note that version 3 of the API, and version 3 of the SDK are deprecated
since version 4.0 of the engine, and they will be removed in version 4.2
of the engine.

There is a general description of version 4 of the SDK here:

  https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/README.adoc

A collection of examples here:

  https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples

And reference documentation here:

  http://ovirt.github.io/ovirt-engine-sdk/4.1

You may also find useful the documentation of the API itself:

  http://ovirt.github.io/ovirt-engine-api-model/4.1

Specially the section that describes how to add virtual machines, as
there is an example of how to add a virtual machine from a snapshot there:


http://ovirt.github.io/ovirt-engine-api-model/4.1/#services/vms/methods/add

> Can anyone help me about how to clone a VM from a snapshot using the

> 

To create a virtual machine from a snapshot with the latest version of
the SDK you will need something like this:

---8<---
import time

import ovirtsdk4 as sdk
import ovirtsdk4.types as types

# This example shows how to clone a virtual machine from an snapshot.

# Create the connection to the server:
connection = sdk.Connection(
url='https://engine.example.com/ovirt-engine/api',
username='admin@internal',
password='...',
ca_file='ca.pem'
)

# Get the reference to the root of the tree of services:
system_service = connection.system_service()

# Find the virtual machine:
vms_service = system_service.vms_service()
vm = vms_service.list(search='name=myvm')[0]

# Find the service that manages the virtual machine:
vm_service = vms_service.vm_service(vm.id)

# Find the snapshot. Note that the snapshots collection doesn't support
# search, so we need to retrieve the complete list and the look for the
# snapshot that has the description that we are looking for.
snaps_service = vm_service.snapshots_service()
snaps = snaps_service.list()
snap = next(
  (s for s in snaps if s.description == 'mysnap'),
  None
)

# Create a new virtual machine, cloning it from the snapshot:
cloned_vm = vms_service.add(
vm=types.Vm(
name='myclonedvm',
snapshots=[
types.Snapshot(
id=snap.id
)
],
cluster=types.Cluster(
name='mycluster'
)
)
)

# Find the service that manages the cloned virtual machine:
cloned_vm_service = vms_service.vm_service(cloned_vm.id)

# Wait till the virtual machine is down, as that means that the creation
# of the disks of the virtual machine has been completed:
while True:
time.sleep(5)
cloned_vm = cloned_vm_service.get()
if cloned_vm.status == types.VmStatus.DOWN:

Hi Folks !

I am looking for a documentation for ovirt-engine-sdk-python-4.1 but could
not find anything yet. Looks like there are many changes compared to 4.0.

Can anyone help me about how to clone a VM from a snapshot using the latest
sdk ?

Thank you !

That is correct, thanks Nathanaël. I have just submitted a patch to
document this in the README.adoc file of the SDK:

  Add installation instructions
  https://gerrit.ovirt.org/73796

Would be nice if you can review that patch.

Juan, it seems that we did not build SDK4 for FC25 in 4.1 or older versions:
http://jenkins.ovirt.org/search/?q=python-ovirt-engine-sdk4_4.1_build-artifacts

So as far as I can tell there is no released SDK4 for FC25 ATM. Only a

Sorry, I forgot you are using Fedora 25, and Fedora 25 isn't yet a

For Fedora 25 you can either build the packages yourself, or else

Juan, it seems that we did not build SDK4 for FC25 in 4.1 or older versions:
http://jenkins.ovirt.org/search/?q=python-ovirt-engine-sdk4_4.1_build-artifacts

So as far as I can tell there is no released SDK4 for FC25 ATM. Only a
pre-released one in the master snapshot.

The best way to get the latest versions of those packages is to install
the oVirt release RPM:

  dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm

Then install the required packages. The names of the packages are
different for version 3 of the SDK and version 4 of the SDK, so you can
install both simultaneously:

  Version 3: ovirt-engine-sdk-python
  Version 4: python-ovirt-engine-sdk4

  yum -y install ovirt-engine-sdk-python python-ovirt-engine-sdk4

Note that version 3 of the API, and version 3 of the SDK, are deprecated
since version 4 of the engine, and that they will be removed in version
4.2 of the engine, so prepare to migrate to version 4.

I'm running some tests in a 4.1 testenvironment.
At the moment testing on a Oracle Linux 7.3 VM

- using oVirtBackup from master (version is on 3rd of July 2016)

$ ./backup.py -c config_test.cfg
Mar 08 17:37:08: Start backup for: Oracle7
Mar 08 17:37:09: Snapshot creation started ...
Mar 08 17:38:23: Snapshot created
Mar 08 17:38:33: Clone into VM started ...
Mar 08 17:40:31: Cloning finished
Mar 08 17:40:32: Snapshot deletion started ...
Mar 08 17:41:53: Snapshots deleted
Mar 08 17:41:54: Export started ...
Mar 08 17:43:56: Exporting finished
Mar 08 17:43:57: Delete cloned VM started ...
Mar 08 17:44:01: Cloned VM deleted
Mar 08 17:44:01: Duration: 6:54 minutes
Mar 08 17:44:01: VM exported as Oracle7_BACKUP_20170308_173708
Mar 08 17:44:01: Backup done for: Oracle7
Mar 08 17:44:01: All backups done

NOTE: during the snapshot creation I see in web admin console the VM in
paused state and also not responsive in both console and ssh session.
After a couple of seconds it comes back and as a confirmation I see this in
its messages:

Mar  8 17:38:57 T-ORACLE73 chronyd[616]: System clock wrong by 19.077230
seconds, adjustment started

Is this expected?

Not yet used the vm_backup.py, I;m trying to get sdk4 on Fedora 25 before
(see the other thread I opened)...

[ovirt-users] Python sdk 4 for Fedora 25 where?

[Gianluca Cecchi]

Hello,
it seems that on my Fedora 25 I'm able to find only ovirt-engine-sdk-python
that is 3.6.9.1
What should I execute to get sdk 4 on Fedora 25?
Can I have both the sdk 3 and 4 for test an a single machine?

Is it realistic to think something similar to the workflow described below,
based on the import storage domain functionality described here:
http://www.ovirt.org/develop/release-management/features/storage/importstoragedomain

and in particular one of its targets:
Transfer VMs between setups without the need to copy the data into and out
of the export domain.


Prerequisite:
- Host1 has network connectivity with Host3
- Host1 is part of a DC that contains an FC based storage domain, composed
of SAN LUN A of X Tb
- Host3 is part of another DC and has connection in place with iSCSI LUN B
of X Tb

Workflow:
- Stop the VMs that are on the source FC domain
- Put source storage domain into maintenance
- Detach source storage domain
- Clone LUN A to LUN B at low level
(eg dd command via network
Similar to when you clone an entire disk from a server to another server
)
- import domain on DC where Host3 lives giving the correct iSCSI
parameters...

Do the OVF_STORE disks on the storage domain contain information about the
fact of it being an FC or an iSCSI storage domain, preventing then a
possible import operation?

This is a test environment where I would like to transfer 4Tb of data from
FC SAN in decommission phase to an iSCSI SAN, and if I can by-pass export /
import phases, even giving some downtime, would be good.

Thanks for reading,
Gianluca

ovirt_nics module is part of the Ansible 2.3, and I guess you are using
Ansible 2.2. That's why it can't find the module.

This is a list of dictionary, so this should be:

nics:
  - name: "{{ nic_name }}"
profile_name: "{{ profile_name }}"

If what you are looking for is a way to add a NIC to an existing VM,
using a specific vNIC profile, you can use this example:

Re: [ovirt-users] DWH reports in 4.X ?

[Eduardo Mayoral]

Thanks for your answer!

Looks certainly interesting. I am using collectd with virt plugin +
carbon + graphite + grafana for performance graphs of the hosts and the
VMs right now ( oVirt 4.1 with nodes in CentOS 7.3)

I like the idea of using fluentd for this instead of a relational
database. Will it handle metrics and logs as well? I am asking because
of the kibana component.

When i remove the commented lines here is what i got:

name, or incorrect module path.

The error appears to have been in
'/Users/oyarimtepe/test/ovirt-ansible/create_vm_from_template/playbook.yml':
line 35, column 11, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

I tried using the nics attribute of ovirt_vms module but this time i got
Nic[Name] is required although i defined as below:

without comments it works. Any idea? Any way to set the nic and profile via

Re: [ovirt-users] oVirt Nodes Monitoring

[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.

Thanks Arsène

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 
following command:


semodule -i zabbix_agent_setrlimit.pp

I see the oVirt Nodes have snmpd service installed and could be used 
for basic things but ideally, for Zabbix is good to use its agent.


What would be the best way to install its zabbix-agent package and 
make it persistent ? Add its repository to the oVirt-Node in 
/etc/yum.repos.d/ and install it with yum or install using a .rpm 
directly ?

Hi Eduardo,

DWH still exists, and if you have a reports tool that supports sql you can
use it with it.
Reports was deprecated in 3.6.

We are now working on adding a new metrics store solution for oVirt.

For more details you can have a look at:
http://www.ovirt.org/develop/release-management/features/
engine/metrics-store/

Currently in 4.1 the hosts and engine include Collectd and Fluentd.
In 4.2 we expect to have the metrics store ready.

You can try setting up the metrics store side from upstream for now.
https://github.com/sradco/ovirt-metrics-conf




The Fluent and Collectd configuration are handled at:

Re: [ovirt-users] oVirt Nodes Monitoring

[FERNANDO FREDIANI]

Thanks Arsène

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 
following command:


semodule -i zabbix_agent_setrlimit.pp

Hi.

How do you guys monitor your hosts with Zabbix ?
I see the oVirt Nodes have snmpd service installed and could be used 
for basic things but ideally, for Zabbix is good to use its agent.


What would be the best way to install its zabbix-agent package and 
make it persistent ? Add its repository to the oVirt-Node in 
/etc/yum.repos.d/ and install it with yum or install using a .rpm 
directly ?

No, my scenario was a planning workflow.
At this moment I only have Host1 and Host2 that are connected to an FC-SAN.
I have to move data to an iSCSI storage and also oVirt hosts to Host3 and
Host4 (yet to be deployed).
So I'm trying to understand if I can do it in pieces bypassing export/import

I forgot that it is DC the constraint for SD accessibility.
Any suggestion to accomplish the desired target?

[ovirt-users] oVirt and Openstack Neutron: network not working

[Luca 'remix_tj' Lorenzetto]

Hello,

i have a oVirt 4.1 setup attached to an openstack newton. I imported a
network from my openstack setup without issues.
I attached a VM to that network, but dhcp isn't working. Tried setting
fixed ip, but still not working. I've seen a new qbr* bridge appeared
and so tried to tcpdump on it. I've seen only arp requests, but no arp
replies.
Openstack is using openvswitch, and here i can use ovs-vsctl show to
see the status of the switch. Here i see instead a linuxbridge. How do
i check if everything is flowing correctly?

Nodes are based on ovirt-node-ng 4.1.

Luca

[ovirt-users] Error on Node upgrade

[FERNANDO FREDIANI]

Hello.

I'm running oVirt-Node *4.1.0--0.20170201.0+1* on my hosts and tried a 
normal upgrade. It detected it has to upgrade to 
*4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos* from the 
ovirt-4.1-pre repository.


The upgrade finished with the following problems:

...
Running transaction
  Updating   : 
ovirt-node-ng-image-4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos.noarch

  Updating   :

2/4
mount: special device /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1 
does not exist

cp: target ‘/tmp/tmp.N6JgSdFcu6/usr/share/imgbased/’ is not a directory
rm: cannot remove 
‘/tmp/tmp.N6JgSdFcu6/usr/share/imgbased/*image-update*.rpm’: No such 
file or directory

umount: /tmp/tmp.N6JgSdFcu6: not mounted
...

So it seems it was not able to do it correctly.
This is the second time it happens and I had to remove manually these 
packages containing 4.1.1 version.


Tried also:

# lvdisplay | grep ovirt-node-ng-4.1.1-0.20170303.0+1
  LV Path /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1
  LV Nameovirt-node-ng-4.1.1-0.20170303.0+1
# fdisk -l /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1
fdisk: cannot open /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1: No 
such file or directory

# vgchange -ay
# fdisk -l /dev/onn_kvm01/ovirt-node-ng-4.1.1-0.20170303.0+1 (then worked)

But the upon reboot it came back to 4.1.0 as if 4.1.1 never existed.

Is there any known solution of a full Node reinstall is the recommended ?

Thanks

The definition for the engine VM is getting extracted by ovirt-ha-agent
from the OVF_STORE volume, not sure why the engine doesn't update it when
you change cluster properties. I think it's work to fill a bug.
Stefano, did you tried simply changing the number of cores for the engine
VM from the engine to force a configuration update?

Re: [ovirt-users] Moving from fc based to iSCSI based

Hi,

Storage domains are per Data Center, and all hosts in this DC should be
able to access the SDs, no matter in which cluster they are...

Are you sure your hosts are on the same DC ?

Re: [ovirt-users] ovirt don't give "initiator name" to cinder when I'm launching a VM with a cinder volume

[herve]

Thanks a lot!

I beleived lvm backend was much easier to implement than ceph an 
obviously should work if ceph was supported...

that was my mistake
Regarding the behvior I got the backend lvm is almost working anyway - )
 I could have been searching during a lot of time ... I'm going to try 
it with ceph...


Thanks again for your quick answer.

 From mi ovirt manager 4.1, I can create and delete a cinder volume or attach

The problem is I never had been able to launch an ovirt VM with a cinder
volume attached to it.
I just got a simple message from ovir web gui:  "Failed to run VM
centoscinder (User: admin@internal-authz)".

what i am using is
a RDO newton release of openstack. the backend of cinder is a local lvm,

Here is your problem, ovirt supports only ceph storage with cinder.

We may add more storage types in the future.

Nir


and
the openstack VMs can use the cinder volumes from other compute node.
from the ovirt 4.1 fedora 24 server:
[root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4
ovirt-engine-4.1.0.4-1.fc24.noarch
ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch
[root@rhevf24 ~]#

from the ovirt server , through the iscsiadm command,  I can see for example
the 2 disks attached to 2 diffents  openstack instances,
but not the one I just created from ovirt which is attached to nothing ,
from the openstack rdo point of view.
[root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36

iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3

as I said previously From ovirt I can create /delete in cinder and
attach/detach volumes to ovirt VMs I don't get any troubles with that.


in ovirt engine.log almost nothing , except it can't aquire lock.. but in
openstack cinder, and with tcpdump I get more informations.
tcpdump give me when ovirt intent the iscsi connection something like:
json.key == "os-initialize_connection"
{.  "os-initialize_connection" : {."connector"  :  {  }, },}

and I get from "tail -f  /var/log/cinder/volume.log" :

Cinder can't obviously guess which one I want. that's more or less what's
the cinder's logs are telling me.

I have searched for a long time in internet, it looks like  at least since
ovirt 3.6, cinder is ont anymore an issue, and can even be integrated with a
ceph back end to ovirt...
cinder model an client are installed in the ovirt server...

Somebody get any clue to tell ma where i made a mistake in the cinder

[ovirt-users] Moving from fc based to iSCSI based

[Gianluca Cecchi]

Hello,
I have to move some VMs from FCP based storage domain to iSCSI based
storage domain.
Can I do it offline or online keeping in mind that:

Host1, Host2 have access only to the FCP SD
Host3, Host4 have access only to the iSCSI SD

They are all managed by the same engine in the same DC but in different
cluster

I suppose it happens through network, correct?
Thanks in advance,

I found the configuration file /etc/ovirt-hosted-engine/hosted-engine.conf
with field sotrage=.
Is it possible to change the value above to put four IP there (four array
interfaces IP)?

The target storage domain for the lease can be set using the Python SDK,
like this:

---8<---
import ovirtsdk4 as sdk
import ovirtsdk4.types as types

# This example shows how to set the storage domain where the lease of a
# virtual machine should be created.

# Create the connection to the server:
connection = sdk.Connection(
url='https://engine.example.com/ovirt-engine/api',
username='admin@internal',
password='...',
ca_file='ca.pem'
)

# Get the reference to the root of the tree of services:
system_service = connection.system_service()

# Find the virtual machine:
vms_service = system_service.vms_service()
vm = vms_service.list(search='name=myvm')[0]

# Find the storage domain:
sds_service = system_service.storage_domains_service()
sd = sds_service.list(search='name=mydata')[0]

# Update the storage machine so that high availability is enabled and
# the lease is created in the selected storage domain:
vm_service = vms_service.vm_service(vm.id)
vm_service.update(
vm=types.Vm(
high_availability=types.HighAvailability(
enabled=True
),
lease=types.StorageDomainLease(
storage_domain=types.StorageDomain(
id=sd.id
)
)
)
)

# Close the connection to the server:
connection.close()

Re: [ovirt-users] iscsi failover MD3820i

[Marcin Kruk]

How to verify this?
In the RHEM GUI storage ->  -> Manage domain  I can see all
fourt target names,
but mabye there is only present state and I shoud verify something else in
the database or wherever?

Where is the info about iSCSI hosted-engine storage target IP,
about other storages information is in the table engine.storage_server_
connections.
I presume that information about iSCSI storage target IP can not be in the
the database due to "chicken or the egg" dillema.

[ovirt-users] Info on network interface threshold alert

[Gianluca Cecchi]

Hello,
this morning I get these two messages regarding bond1 and its active
interface on one host (ovmsrv07):

Host ovmsrv07 has network interface which exceeded the defined threshold
[95%] (bond1: transmit rate[96%], receive rate [0%])

Host ovmsrv07 has network interface which exceeded the defined threshold
[95%] (enp7s4f0: transmit rate[96%], receive rate [0%])

Actually there is no particular network activity during this latest night...
There have been some different resore jobs during past days...
How is determined this message? Is it perhaps cumulative?

On the host there are 3 VMs and only one of them actively using the network.
In its "Network Interfaces subtab I see
Total RX (bytes)
542,696,952,529

Inside VM OS:

Almost confirmaed on host where I have these counter indeed, but I think
they are cumulative for the VM, and not an alert in se

Re: [ovirt-users] ovirt ansible module

I didn't see any parameter at the current ansible documentation related
with these features. How can i set these feature if i am using ansible? Any
possibility to set them via SDK after the vm is opened via ansible?

[ovirt-users] ovirt don't give "initiator name" to cinder when I'm launching a VM with a cinder volume

[herve]

dear ovirt user community,

I can't sort out an ovirt issue I got with cinder for weeks, I hope 
someone could give me a clue...
From mi ovirt manager 4.1, I can create and delete a cinder volume or 
attach and detach a cider vomume from an ovirt  VM.


The problem is I never had been able to launch an ovirt VM with a cinder 
volume attached to it.
I just got a simple message from ovir web gui:  "Failed to run VM 
centoscinder (User: admin@internal-authz)".


what i am using is
a RDO newton release of openstack. the backend of cinder is a local lvm, 
and the openstack VMs can use the cinder volumes from other compute node.

from the ovirt 4.1 fedora 24 server:
[root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4
ovirt-engine-4.1.0.4-1.fc24.noarch
ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch
[root@rhevf24 ~]#

from the ovirt server , through the iscsiadm command,  I can see for 
example the 2 disks attached to 2 diffents  openstack instances,
but not the one I just created from ovirt which is attached to nothing , 
from the openstack rdo point of view.

[root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36
192.168.122.36:3260,1 
iqn.2010-10.org.openstack:volume-f4c6c55c-e383-4781-8d24-d41b55870d29
192.168.122.36:3260,1 
iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3


as I said previously From ovirt I can create /delete in cinder and 
attach/detach volumes to ovirt VMs I don't get any troubles with that.



in ovirt engine.log almost nothing , except it can't aquire lock.. but 
in openstack cinder, and with tcpdump I get more informations.

tcpdump give me when ovirt intent the iscsi connection something like:
json.key == "os-initialize_connection"
{.  "os-initialize_connection" : {."connector"  :  {  }, },}

and I get from "tail -f  /var/log/cinder/volume.log" :
2017-03-07 16:45:06.889 3856 ERROR cinder.volume.targets.iscsi 
[req-b6d39a14-f9ea-4552-91e7-5db811217b1e 
dd1dd33789274fb7ba228c75a07c0e94 0f68893965dd4f5dafd319cbffb33bb4 - 
default default] The volume driver requires the iSCSI initiator name in 
the connector.

...
...
2017-03-07 16:45:06.891 3856 ERROR oslo_messaging.rpc.server 
InvalidInput: Invalid input received: Connector doesn't have required 
information: initiator



So it looks like I didn't get  or I can't provide the initiator name I 
want to be connected to.
Cinder can't obviously guess which one I want. that's more or less 
what's the cinder's logs are telling me.


I have searched for a long time in internet, it looks like  at least 
since ovirt 3.6, cinder is ont anymore an issue, and can even be 
integrated with a ceph back end to ovirt...

cinder model an client are installed in the ovirt server...

Somebody get any clue to tell ma where i made a mistake in the cinder 
integration with ovirt , which seems to be correct regarding the 
create/delete attach /detach volume behavior...


Thank you

Herve

[ovirt-users] Second node ovirt 4.0 no ovirtmgmt bridge, non-operational issue

[Ian Neilsen]

Hi all

I currently have a non-operational second node in my "ovirt 4.0
hosted-engine" installation running on Centos7, kernel
3.10.0-514.10.2.el7.x86_64.

When I ran "hosted-engine --deploy" on the second node, it produce the
following error(see bottom of email).

I now cannot set the second node into operational mode, no matter what I
try. I did notice a few things though.

#1 - no ovirtmgt bridge was created during hosted-engine deploy; should I
create this bridge and retry?
#2- vdsmd keep throwing start errors before I ran hosted-engine deploy. I
ran vdsm-tool configure --force this seem to fix it.
#3 - second node complained of no fencing agent, so I added in a DRAC fence
agent and it worked/tested fine. But still not able to go opertional on
second node.
#4 Ive tried restarting vdsmd, ovirt-ha-agent and ovirt-ha-broker. Both the
agent and broker throw error messages.(see bottom of email for errors)

Any advice of where to look next, what to fix?
