[ovirt-users] Failed to activate Storage Domain infer (Data Center Default) by admin

[William Kwan]

hi all,
I still have the lock error which I need some help to resolve. I found some 
posts used sanlock command. But I'm not sure if it fit in my case. Thanks in 
advance. libvirtError: Failed to acquire lock: No space left on 
deviceThread-49::DEBUG::2016-05-13 
22:02:49,693::vm::2779::vm.Vm::(setDownStatus) 
vmId=`bd48bba5-4109-4a58-ac89-832add1f4de4`::Changed state to Down: Failed to 
acquire lock: No space left on device 

I wasn't able to bring up the hosted-engine on Node1 and I got the above error. 
 I was able to run `hosted-engine --start-pool` on Node2, but not Node1.
#hosted-engine --start-poolConnecting Storage Pool
Starting SPMf5f78fb8-42e3-46e5-93c2-6c3b00914048Activating Storage 
DomainResource timeout: ()


With the "Storage pool" up on Node2, I was able to start the hosted-engine.  
But when I try to active the Master storage domain called 'infra'
"Host cannot access the Storage Domain(s)  attached to the Data Center 
Default. Setting Host state to Non-Operational""Failed to connect Host to 
Storage Pool Default"
Tried again and I would get "Failed to activate Storage Domain infra (Data 
Center Default)"

Re: [ovirt-users] no network with matching name 'vdsm-ovirtmgmt'

[William Kwan]

Hi all,
There was an issue with sudoers syntax.  Vdsm didn't start correctly so 54321 
wasn't available.After fixing it, I got some errors on locks.  I'm not sure how 
this should be fixed correctly.

Re: [ovirt-users] no network with matching name 'vdsm-ovirtmgmt'

[William Kwan]

OK. I should change the subject to "failed to start oVirt 3.5".
I found a bugzilla page with the following.  It seems to work fine after I 
replaced 'dhcp' with 'none' on two networks.  "Fixed by manually removing 
'dhcp' from /var/lib/vdsm/persistence/netconf/nets/$NETWORK" 
When I try to bring up the hosted engine with `hosted-engine start`, I get # 
hosted-engine --vm-startConnection to localhost:54321 refused
Still working on 'recovery'.

Re: [ovirt-users] Hosted Engine Appliance hostname causing issues in production environment

[Langley, Robert]

I’m not quite sure about configuring the appliance with cloud-init. I think I 
might know what you mean. Maybe that is the part of the setup that did not 
happen for me.
I ended up creating my own hosted engine with a CDROM ISO to get me going today.
Thank you.

Did you try configuring the appliance with cloud-init?
Can you please attach hosted-engine-setup logs?

Ok thanks, but now I'm checking the rsdl (I should have done that earlier) and 
see :


disk.lun_storage.type


disk.lun_storage.logical_unit


logical_unit.id


logical_unit.address


logical_unit.port


logical_unit.target




Given the output for a existing SAN disk, I see :


SHP_MSA_2040_SAS_00c0ff26285a209135570100
HP
MSA 2040 SAS
33
1099511627776
0
dd98b206-08e4-48c0-9795-d10bc7581a95


There is no address, port or target, that are needed only for iscsi. I tried 
without and everything was fine. So I think they are not required.

Re: [ovirt-users] VMs seems to be slow, while snapshot delete is happening

Hi All,

I have created a VM with 60GB of disk space.
I have started I/O inside the VM, after sometime when the disk was 4GB full,
I took a snapshot of the disk from UI.

I/O kept continuing and the new image file ( overlay file ) was 15GB in
size.

Now I deleted the snapshot.
I think this would initiate block-merges.
During this time, my I/O was were slower, till the snapshot delete is
completed.

Its not very slow, but slow.
Is this a known behavior ?


Hi Satheesaran,

It sounds like this was a live merge, ie snapshot removal while the VM was 
running.  This is currently implemented as a block commit, where data from 
the snapshot (your 15GB overlay, in this case) is merged down.


For snapshot deletion to complete, this means that your concurrent I/O and 
the data already in the overlay have to be written into the next-lower 
image.  So in short, yes, depending on the storage system backing your VM, 
I/O may slow down a bit until completion.

Re: [ovirt-users] RemoveDiskSnapshots error's on engine log

Hi List

At the moment, we replace a filer and we have to move the VM's to
another filer. We have a lot of problems with it. Sometime we have to
restart the engine, sometime we have to move the image arround and
sometimes we don't have a chance to remove the snapshots. When the VM is
running, most of the time the snapshot remove never starts.

Now, i found these errors every second in the engine.log since today:

2016-05-11 23:25:29,102 ERROR

I try everything, but i can't find the problem.

Anyone who have an idea, where i have to search?


Hi Ivo,

I'm not sure what would cause this to start happening after a successful 
deployment, but perhaps enabling debug logging would help narrow it down. 
 See [1] for instructions on that.

Hi Marcelo,

I see in your engine log that one of the images can't be found when a 
merge is attempted:


  VDSErrorException: Failed to MergeVDS, error = Drive image file could
  not be found, code = 13

There were some recent fixes to Live Merge that help is progress beyond 
this particular error, see [1] for details on that.  The fix is in 3.6.6.


It might be helpful to check the vdsm log to see what happened on the host 
when the first merge on that snapshot was attempted.  It should be in the 
Host04 log around time 2016-05-11 19:33:43.


Thanks,
Greg

When creating a LUN disk you need to specify the type (fcp or iscsi)
inside the "lun_storage" element, so you need to send an XML document
like this:

  
virtio

  fcp
  

  

To do that with the Python SDK you need the following code:

  params.Disk(
interface='virtio',
lun_storage=params.Storage(
  type_='fcp',
  logical_unit=[
params.LogicalUnit(
  id='0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-2',
),
  ],
),
  )

Vdsm tries to connect to supervdsmd on startup, and if it is not running
it will fail.

You can do:

systemctl start supervdsmd

And they you can run vdsmd from the shell.

But why do you need to run vdsm from the shell?

Did you try configuring the appliance with cloud-init?
Can you please attach hosted-engine-setup logs?

I need to poweroff the engine VM, I get in trouble. Because, then the
hostname goes back to localhost.localdomain.localdomain and both DHCP & DNS
within our enterprise/production environment ends up assuming that for the
hostname to IP address reference or record. And it seems that other linux
systems (not the ones I administer; none of my almost 50 systems are
effected. Of those, I have about 5 linux/UNIX based systems attached to the
production network) are going offline because of this.

I tried bringing up the OVA of the appliance within VirtualBox, but that
doesn’t work. Is there another virtual software I can bring up within a
Windows PC to simply edit the hostname, then export the appliance again?

Vdsm tries to connect to supervdsmd on startup, and if it is not running
it will fail.

You can do:

systemctl start supervdsmd

And they you can run vdsmd from the shell.

But why do you need to run vdsm from the shell?

You should not touch directories under /run/vdsm/storage or /rhev/data-center,
they should not have any negative effect on the system.

Please open a bug - this should never happen.
https://bugzilla.redhat.com/enter_bug.cgi?product=vdsm
oVirt team: Infra
Severity: High

Vdsm must set the socket option socket.SO_REUSEADDR
before binding.

Ensuring that only one vdsm instance is running must be
done elsewhere if needed, for example using a lock file.

[ovirt-users] creation of lun disks

[Fabrice Bacchella]

I'm trying to generated a lun disk, using the python SDK.

My code can be found at 
https://github.com/fbacchella/ovirtcmd/blob/master/ovlib/disks/__init__.py

If a try to see the content of a existing disk and test with :
print disk.get_type()
print disk.get_storage_type()

I'm getting :
None
lun

Now I try to create another LUN disk with
kwargs['storage_type'] = 'lun'
kwargs['type_'] = 'system'

I'm getting:

> POST /api/disks HTTP/1.1
> 
> system
> virtio-scsi
> 
> 
> 
> lun
> 
...
< 
< Incomplete parameters
< Storage [type] required for invoke0
< 

changing to 
kwargs['type_'] = None 
change nothing, I'm still getting the same error message.

> POST /api/disks HTTP/1.1
> 
> virtio-scsi
> 
>

 What did I do wrong ? There is nothing about that in the logs

If you mean by "datacenter" the datacenters inside one ovirt installation then 
it should work and you should see VMs from all of them (with ability to filter 
by cluster).

If you mean several ovirt installations than it is not implemented, but it is 
one of the things we would like to implement.
So I have opened an issue for it: https://github.com/matobet/moVirt/issues/174

Re: [ovirt-users] Trying to understand the mixed storage configuration options.

[Jason Ziemba]

Nir,

The use cases of my current configuration is a mix of duplicated data
clusters (Percona/Consul/CouchBase) and ephemeral systems (web servers)
that work perfectly when 'locked' to a local host  These are built in such
a way that losing a physical host reduces redundancy but isn't outwardly
service degrading.  The other side is the duplicated databases (namely
Percona) that would induce a fairly high level of NAS bandwidth that is
avoided when they leverage the local storage on their host system.

The goal would be to have the ability to house the highly redundant and/or
ephemeral systems to be housed on the hosts local storage, whereas guests
that need HA or one-offs would be housed using the NAS allowing seamless HA
or online migration.

[ovirt-users] [moVirt] Add several datacenters

[Nicolas Ecarnot]

Hello,

I finally was able to correctly connect to one of our DC with moVirt, so 
I can show off and it is so cool.

But I find no way to add several datacenters.

May someone help please?

Re: [ovirt-users] Trying to understand the mixed storage configuration options.

[Pavel Gashev]

Nir,

Basically, almost any server has a local storage. It could be a reliable, RAID 
enabled storage. It would be great to allow to use it simultaneously with 
shared storages.

Other virtualizations like vmware/hyperv support local and shared storages 
simultaneously. If your VM is on local storage, it's tied to a host. Just like 
when VM has attached local device(s). VM migration moves disks between hosts as 
well.

An obvious solution is to export local storages via NFS to make it shared. This 
would allow to drop «local storage datacenters» as a class.

TODO list would be the following:
1. VDSM: add creating NFS exports
2. Engine: creating NFS exports before local storage activation, and updating 
NFS exports after adding/removing hosts
3. Engine: add moving disks between storages during (just before, just after) 
VM migration. 
4. Engine: add constraints to avoid dangerous situations - disallow changing VM 
startup host, disallow moving disks to another local storage without VM 
migration, etc.

Re: [ovirt-users] Adding another host to my cluster

[Charles Tassell]

Hi Gervais,

  Okay, I see two problems: there are some leftover direcyories causing 
issues and for some reason VDSM seems to be trying to bind to a port 
something is already running on (probably an older version of VDSM.)  
Try removing the duplicate dirs (rmdir 
/var/run/vdsm/storage/248f46f0-d793-4581-9810-c9d965e2f286 and 
/rhev/data-center/mnt - if they aren't empty don't rm -rf them because 
they might be mounted from your production servers.  Just mv -i them to 
/root or somewhere.)


  Next shutdown the vdsm service with "service vdsm stop" (I think, 
might be service stop vdsm, I don't use CentOS much) and kill any 
running vdsm processes (ps ax |grep vdsm)  The error that I saw was:


MainThread::ERROR::2016-05-13 
08:58:38,262::clientIF::128::vds::(__init__) failed to init clientIF,

If you get the same error, do a netstat -lnp and compare it to the same 
from a working box to see if something else is running on the VDSM port.

Re: [ovirt-users] Changing of master storage domain

[Nicolas Ecarnot]

Le 13/05/2016 12:06, Nir Soffer a écrit :

Nir,

Would there be any benefit thus any plan to add the feature to be able to
select the master domain, the same way we can do it with the SPM?


I don't know about any benefit.


There could be cases where we would want to free a storage domain from being
master, but without putting it into maintenance.


Like?


At multiple times, I had to do maintenance actions on the SAN side which 
are neither SUPPOSED to break anything, nor be visible by oVirt, but in 
case of failure, I would have been glad to choose which storage domain 
to preserve at all cost, though not putting any SD into maintenance.


It is often related to external actions not driven by oVirt, but as 
oVirt as a potential side-effect victim. (other examples related to 
network modifications)




We are working now on removing the master domain (part of spm removal). It is
unlikely that we will add any feature related to the master domain.


Well, I couldn't hope more, that will be perfect.

4.x ?

Thank you Nir.

[ovirt-users] IsolatedNetworks

[Winfried de Heiden]

Hi All,

As described on http://old.ovirt.org/Features/IsolatedNetworks,
Isolated networks in one of proposed features of oVirt 4.0:

"The current host networking api (up to ovirt-engine-3.6) requires a
network to be configured on top of a network interface.

In order to configure a local network on the host the user had to
create a dummy interface to which the network was attached.

The Isolated Networks feature aimed to configure a local host on the 
network which isn't connected to any network interface and allows vms 
which are connected to it to communicate with each other.

Isolated Networks will be limited to VM networks only and only MTU 
should be relevant in that network definition for the created isolated 

network."

Hence, I should be able to create a host-only network with an
underlaying NIC; sounds nice for my @home Cloud...

However, runing oVirt 4.0 it is still complaining a NIC is misssing. I
might have configured something wrong. How to set create an isolated
network? Is there already any documentation?

Kind regards,

Winny

I checked the code, and we actually do use volume_utilization_chunk_mb when we 
create the initial disk, so getting the configuration to work will solve your

This looks correct if this is in the [irs] section of the configuration.

[irs]

# Together with volume_utilization_chunk_mb, set the minimal free # space

# volume_utilization_percent = 50

The initial volume size is always 1GiB, regardless of these settings.

After creating 1GiB lv, we extend the lv volume_utilization_chunk_mb megabytes.

So your setting will result in 1GiB lv, and after you write about 150MiB, it 
will be extended to 5GiB.

So I guess that you want to use
volume_utilization_chunk_mb = 3072

Which will give you 4GiB lv after the first extend.

We support initialSize argument when creating volumes - use when importing 
external vms (v2v), but it is not exposed in the ui.

If you think think exposing it in the ui is a useful feature, you can file a 
bug:

This is not available by design.

Can you explain the use case, why do you need to use local storage as
your primary data storage?

How are you going to migrate your vms if the primary storage is local?

How are you going to start the vms on another host after host failures,
if the vm storage is on the failed host, and the last state of that disk
is not available or even lost?

No chance for 4.0.

It is unlikely that we will work on it before removing the spm and the
master domain. Without spm and master domain, this change should be
easier.

Having access to all storage domains from all hosts in a dc is the basic
design assumption. Having some domains which are accessible only from
some hosts is a major change.

I think we have one, and you can vote on the bug (I don't have the bug

Can you explain what they are doing and how it can benefit ovirt?

[ovirt-users] volume_utilization_chunk_mb not working

[Grundmann, Christian]

Hi
I create a lot of Thin Disk VMs from templates every day, and get "paused due 
to no storage space error" and "paused due to unknown storage error" on a few 
of them.
Sometimes the VMs are resumed a few seconds later but sometime not, but I can 
resume them myself.

I tried to set
volume_utilization_percent=15
volume_utilization_chunk_mb=4048

in /etc/vdsm/vdsm.conf on every Host

But the Initial Size of the Disk is always 1GB and then increments to 2GB

4GB would be the maximum Size I need before I destroy the VM. So if the initial 
Size would be 4GB the pausing shouldn't happen anymore

Thx a lot for your help
Christian

Like?

We are working now on removing the master domain (part of spm removal). It is
unlikely that we will add any feature related to the master domain.

Re: [ovirt-users] vms in paused state

[Milan Zamazal]

We've found out that if libvirtd got restarted then VMs with disabled
memory balloon device are wrongly reported as being in the paused state.
It's a bug and we're working on a fix.

You cannot select the master domain, the master is selected
automatically by ovirt.

You can move the master domain from the current domain by putting the domain
to maintenance, the system will move the master to domain to another domain.

Nir,

Would there be any benefit thus any plan to add the feature to be able 
to select the master domain, the same way we can do it with the SPM?


There could be cases where we would want to free a storage domain from 
being master, but without putting it into maintenance.

Re: [ovirt-users] ovirt 4.0 alpha web login error

[Martin Perina]

Hi,

there is no way how to disable SSO in oVirt 4.0. And IMO there's no need to
do that, because the change from previous login mechanism (separated logins
for webadmin, userportal and restapi) should be fully transparent. The only
way necessary is to set proper FQDN during engine-setup and use always this
FQDN always when accessing engine.

But please bear in mind, that you are using alpha version so there may be
bugs ...

If ovirt-engine-rename doesn't works for you, then you may be hit by
https://bugzilla.redhat.com/show_bug.cgi?id=1330168 which fixed in beta
release ...

Thanks

Martin Perina
