[ovirt-users] HE multipath problem.

[gflwqs gflwqs]

Hi List,

I have installed the hosted engine over iscsi but have a problem getting it
to install over the multipath, even though i can see the multipath device
from the host with multipath -ll.

When i get to the point in the HE installer where i should choose the disk
i only see the underlying devices like sdb sdc. So if i choose one of those
it results in that it will only use one of the paths!

My questions is:
- Is there a bug in the installer script or am i doing something wrong?
- I now have a running HE and would like to manually change the single path
to dual, how do i accomplish this?

I am running  ovirt 3.5.6.2.

Regards
Christian

[ovirt-users] Several VM's stuck in Migration

[Mark Steele]

Hello,

We recently had our storage array hang. We were able to get the disk array
back online, however several of our VM's attempted to migrate from one Host
to another. Now that the storage is online, several of the VM's still
indicate they are in a state of migration and I cannot manage them from
withing the ovirt engine web administration gui.

Most of the VM's are actually running properly and I can access them either
via ssh or RDP (depending on the OS).

I have attempted to clear the migration status with the following:

- service ovirt-engine restart (on the ovirt-engine vm)
- reboot ovirt-engine vm
- PGPASSWORD=### ./unlock_entity.sh -t vm vm-name
- restart the vm from within the vm

additionally - i went on the HV of one of the VM's and did:

vdsClient -s 0 destroy vm_guid

unfortunately, that removed all traces of the vm from that HV and it was
not on any of the other three HV's - although ovirt-engine still shows it
and reports it as migrating.

I'd like to clear the migrating status of the affected VM's and figure out
how to recover the missing one.

Any help would be appreciated. I am not the person who originally setup the
ovirt installation, so I am not sure where to go to pull logs.

Thank you for your assistance.

Re: [ovirt-users] Can't remove snapshot

[Rik Theys]

Hi,

In the mean time I've noticed the following entries in our periodic
logcheck output:

Feb  3 09:05:53 orinoco journal: block copy still active: disk 'vda' not
ready for pivot yet
Feb  3 09:05:53 orinoco journal: vdsm root ERROR Unhandled

This is from the host running the VM.

Note that this host is not the SPM of the cluster. I always thought all
operations on disk volumes happened on the SPM host?

My question still remains:

Re: [ovirt-users] HE multipath problem.

[Elad Ben Aharon]

Hi,

Deployment over more than one path is currently not supported. There is a
request for it: https://bugzilla.redhat.com/show_bug.cgi?id=1193961
I can't think of a way for manually change to dual paths and keep the VM
running without interruptions.

Adding Simone and Nir who might have an idea.

for password field it’s an exception and it’s explicitly logged with *. of 
course the proper secret password is supplied to libvirt. 
But as a generic field elsewhere …they are not getting hidden….all the 
parameters would look like * which is not helpful:)

 Hi Simone,

 I have exactly as you stated, but found maybe a problem/bug.

 1. I put hosted engine to maintenance and powered it off
 2. Changed memory in /etc/ovirt-hosted-engine/vm.conf to memSize=8192
 3. I restarted both ovirt-ha-agent and ovirt-ha-broker: 
 /etc/init.d/ovirt-ha-broker
 restart && /etc/init.d/ovirt-ha-agent restart
 4. I started hosted-engine and turned off global maintenance.

 The hostedengine webinterface still says 4096MB

 Now I logged on with ssh and ran the command "free -m"
 This command shows:

 Mem:  7870   ...
 So, I believe my hostedengine was updated, but the webinterface is
 showing incorrect values: http://screencast.com/t/Bg5xU0Ja

 Any idea why web interface is not showing correct value under Defined
 or Physical memory?

He said that 'I am running oVirt 3.6 with CentOS 6 Hosts with hosted engine
on nfs3',
so the hosts are still at 3.5 and so the cluster compatibility level and so
no auto-import at all.

that might be similar issue as below, unless it’s an upgrade from 3.5.
in which case bug 1297404 might be relevant for the console part

doesn’t sound likely, i would more suspect the import HE 3.6 feature, adding Roy
originally there were no further config updates to external VMs once it was 
added

Re: [ovirt-users] howto change hosted-engine config memory

[Paul Groeneweg | Pazion]

That is correct.
Hosted engine was installed on 3.4 and upgrade several times.

Let me know if you need any additional info.

 You are not the first that reports that: it seams that it's just a
 timeout/refresh issue and you have just to wait. Adding Michal here.

 1. I put hosted-engine to maintenance, shutdown vm
 2. update /etc/ovirt-hosted-engine/vm.conf
 3. restart vm disable maintenance

 Memory is still old value.
 How can I change the hosted engine VM?

 I did found:
 http://www.ovirt.org/Features/Hosted_Engine_configuration_on_shared_storage

 When I check /etc/ovirt-hosted-engine/hosted-engine.conf there is
 no
 "conf_volume_UUID" entry.

 Do I need to create a shared config volume entry ( conf_volume_UUID
 ), so I can edit hosted engine VM? If so, how can this be done?

 I did try to rerun engine-setup, but this did not trigger anything.

 Kind regards,

The scenario of manually connecting the hosted-engine host to several paths
wasn't tested before, but by theory it should work.
As you said, the host should be set to global maintenance, disconnected
from the single iSCSI session [1] and reconnected to the dual paths [2].
Then host re-activation.

 # iscsiadm -m node -o delete
[2] # iscsiadm -m discovery -t sendtargets -p target_IP:port
# iscsiadm -m node target_name -l

Simone, what do you think, will it be possible to add targets in

 Hi,

 Deployment over more than one path is currently not supported. There is
 a request for it: https://bugzilla.redhat.com/show_bug.cgi?id=1193961
 I can't think of a way for manually change to dual paths and keep the
 VM running without interruptions.

 Adding Simone and Nir who might have an idea.

Re: [ovirt-users] HE multipath problem.

[gflwqs gflwqs]

Yes but i have to change the config for the HE in
/etc/ovirt-hosted-engine/hosted-engine.conf so how should that look like?
There is only one variable for storage and since there is dual pathing
there is 2 ip:s so is there some other config for multipathing?

storage=x.x.x.x

 Hi List,

 I have installed the hosted engine over iscsi but have a problem
 getting it to install over the multipath, even though i can see the
 multipath device from the host with multipath -ll.

 When i get to the point in the HE installer where i should choose the
 disk i only see the underlying devices like sdb sdc. So if i choose one of
 those it results in that it will only use one of the paths!

 My questions is:
 - Is there a bug in the installer script or am i doing something wrong?
 - I now have a running HE and would like to manually change the single

 I am running  ovirt 3.5.6.2.

Re: [ovirt-users] How does VDSM-Fake actually work?

[nicolas]

Anything?

El 2016-02-02 10:18, Nicolás escribió:

Hi,

 I'm trying to set up VDSM-Fake
(git://gerrit.ovirt.org/ovirt-vdsmfake.git) for some tests, however,
I'm a bit confused about how does it actually work. As the
instructions say, I was able to build the project with Maven (however,
the org.ovirt.vdsm-jsonrpc-java dependency version had to be changed
to 1.1.5 instead of 1.1.2-SNAPSHOT in pom.xml as this latter is no
longer provided at the repository).

 Once built, I run mvn jetty:run and the server started correctly:


2016-02-02 11:01:51.957:INFO::jetty-6.1.26 [1]
2016-02-02 11:01:52.804:INFO::No [2] Transaction manager found - if
your webapp requires one, please configure one.
2016-02-02 11:01:53,424 Application initialized.
2016-02-02 11:01:53,442 Opening a Stomp server localhost:54322
2016-02-02 11:01:53.702:INFO::Started [3]
SelectChannelConnector@0.0.0.0:54321
[INFO] Started Jetty Server
[INFO] Starting scanner at interval of 10 seconds.

 I could indeed verify it's listening on the VDSM port:


[root@host ovirt-vdsmfake]# netstat -atpn | grep 54321
tcp6   0  0
:::54321   
:::*    LISTEN 
44870/java

 So the next step is to add a fake host via REST. I used scripts
provided here [4] and I successfully added the host, however, it
starts installing all the VDSM packages as it were a normal host and
therefore it tries to start vdsmd as well, which throws an error as
the Jetty Server is already listening on the 54321 port. I shut down
the Jetty Server and allowed oVirt Manager to install all the packages
properly, then stopped vdsmd and started the Jetty Server, but
expectedly oVirt Engine fails with message "Host xxx is non
responsive", so what I actually got is a real VDSM host and not a fake
one.

 FWIW, the fake VDSM runs on a different host, ports are reacheable
from the oVirt engine, proper /etc/hosts has been added to the engine
to reach the host, and no further customization of web.xml has been
done.

 I feel like I'm missing something here. Could someone shed some light
on what's wrong?

 Thanks.

 Nicolás

[ovirt-users] Fwd: Issues Recovering NFS After Power Outage

[Chris Paquin]

Solved: Since my DNS server was down (as it runs in the RHEV environment) the 
hosts could not resolve the name of the NFS server.


Thread-21::ERROR::2016-02-03 
18:25:35,654::storageServer::213::Storage.StorageServer.MountConnection::(connect)
 Mount failed: (32, ';mount.nfs: Failed to resolve server 
freenas.lab.localdomain: Name or service not known\n')


Adding static entry to resolv.conf on each hypervisor solved the issue. Next 
time I will mount via IP address instead.

Please help. After a power outage all my nfs mounts (from two sources) are 
down. I have verified that they are mountable on my workstation.

I have tried to active my NFS Data Master, however the process fails with the 
message below.


Failed to Reconstruct Master Domain for Data Center Auburn_Datacenter.

Can someone assist in recovery?  I have seen posts mentioning that I need to 
verify that the rhev-m hosts can mount the storage, but whats rhev-m way to do 
that. I am assuming I am not just going to mount it via "mount".

[ovirt-users] API: detailed quota information, where's it at?

[Tim Bielawa]

I've been able to run the simple commands to enumerate quotas in a
datacenter, and to select a quota by name.

What I can not figure out how to do is how to receive detailed information
about a quota from the API.

Here's how I queried the basic information (using the python ovirtsdk
module):

import ovirtsdk.api
> api = ovirtsdk.api.API(url=url, username=name, password=password, ...)
> datacenter = api.datacenters.get(name="my-data-center")
> team_quota = datacenter.quotas.get(name="my-teams-quota")


Which works well enough, but doesn't really provide any actual *valuable*
information (just the name, id, description, that kind of stuff).

So where is the useful stuff hidden? The stuff of real value? I have not
found any useful resources while scouring the Internet for this answer.


I want to be able to hit this API and ask for detailed information about
the usage of a quota: How much capacity is my team allotted on a given
storage domain? How much capacity are we presently consuming? Likewise with
CPU/Memory allocation type quotas.

Is this possible, or a pipe dream?


Environment:

RHEVM Version: 3.5.6.0-1
Python SDK Version: 3.5.6.0-1


Thanks again folks!

I don't see any possible workaround here. We need to implement something in
ovrt-ha-agent for that, it's an RFE for 4.0, let's see if we can get it

Re: [ovirt-users] Disabling migration when there is a problem with storage

[Ala Hino]

Hi Mark,

You can disable VM migration:
When editing a vm, in the 'Host' tab there is 'Migration option' drop-down 
where you can choose 'Do not allow migration' or 'Allow manual migration only'.

Hope this helps.

Ala

[ovirt-users] Disabling migration when there is a problem with storage

[Mark Steele]

Hello,

I'd like to know if there is a way to configure ovirt (oVirt Engine
Version: 3.5.0.1-1.el6) to NOT migrate VM's when there is a problem with
attached storage.

Scenario - our storage array that hosts all our VM disks failed. When that
happened, ovirt attempted to migrate running VM's from one host to another.
Unfortunately this left many of the VM's in a 'migrating to' state that
could only be resolved by restarting the HV's

I'd prefer to have ovirt simply hang the VM's until disk IO returns.

Is this possible?

Ah ok, then the latter sentence applies:) there are no further updates to the 
HE VM configuration. And most of the values(including console) are just made up
That's what 3.6 autoimport is improving(again, I'm not sure about the updates 
later on)

 I think I did not restart broker and agent before going out of

[ovirt-users] Consolidating LUNs in iSCSI storage domain

[Colin Coe]

Hi all

In one of our RHEV setups (v3.5.4) the iSCSI storage domain consists of
four LUNs.  (full details in the attached text file).

I want to consolidate all the data on LUNs
iqn.2003-10.com.lefthandnetworks:iscsi:341:rhev-data01
qn.2003-10.com.lefthandnetworks:iscsi:453:rhev-data02
iqn.2003-10.com.lefthandnetworks:iscsi:518:rhev-data03
to LUN
iqn.2003-10.com.lefthandnetworks:iscsi:687:rhev-data04

Is this possible?

Thanks

[ovirt-users] All snapshots read only

[Colin Coe]

Hi all

I've just noticed that all VM snapshots on one of our prod RHEV setups have
gone read-only (i.e. delete is greyed out).

Has anyone else seen this?

Is there an easy fix for this?  We have a bunch of VVMs being snapshotted
nightly with snapshots being deleted after 7 days.

Thanks

That is pretty much what libvirt does. The sandy-bridge, haswell and other
cpu's that we expose are not really a CPUs, but sets of flags (called
baseline CPUs in libvirt's terminology).

Afaik there should be no issue running cluster with both CPU vendors,
the problem is lack of testing on devel side as we mostly run
single vendor clusters everywhere.

[ovirt-users] Issues Recovering NFS After Power Outage

[Chris Paquin]

Please help. After a power outage all my nfs mounts (from two sources) are 
down. I have verified that they are mountable on my workstation.

I have tried to active my NFS Data Master, however the process fails with the 
message below.


Failed to Reconstruct Master Domain for Data Center Auburn_Datacenter.

Can someone assist in recovery?  I have seen posts mentioning that I need to 
verify that the rhev-m hosts can mount the storage, but whats rhev-m way to do 
that. I am assuming I am not just going to mount it via "mount".

Re: [ovirt-users] Disabling migration when there is a problem with storage

[Dan Yasny]

When a storage error occurs, VMs should pause, not migrate. However, if the
VMs were io-idle, then pause (qemu EIO) might have not been triggered
before hosts started dropping into non-op.
...which triggered a migration storm for HA-enabled VMs, racing with VMs
pausing somehow (can't tell without diving into the logs for sure).

I haven't seen it happen in any of my setups, probably a new issue

Re: [ovirt-users] Mixing CPU types

[Matthew Trent]

?Actually it works great! It's been supported by KVM for a while now. I had one 
Proxmox cluster with a mix of AMD and Intel and migrated KVM VM's between them 
frequently. OpenStack (KVM) and VMWare support this as well.


The trick is to expose a virtual CPU with a common set of features to the VMs. 
KVM handles the rest. From the KVM FAQ:

http://www.linux-kvm.org/page/FAQ#Does_KVM_support_live_migration_from_an_AMD_host_to_an_Intel_host_and_back.3F


"Does KVM support live migration from an AMD host to an Intel host and back?


Yes. There may be issues on 32-bit Intel hosts which don't support NX (or XD), 
but for 64-bit hosts back and forth migration should work well. Migration of 
32-bit guests should work between 32-bit hosts and 64-bit hosts. If one of your 
hosts does not support NX, you may consider disabling NX when starting the 
guest on a NX-capable system. You can do it by passing "-cpu qemu64,-nx" 
parameter to the guest."

Y.



I'm using a bunch of re-purposed servers with a mix of AMD and Intel. I 
separate them into clusters, as noted, but it sure would be nice to be able to 
live migrate between them. :)
