[ovirt-users] iSCSI LUN recommended sector size

[William Cooley]

I'm setting up a new iSCSI LUN / volume and am wondering what the recommended 
sector size is.

The setup wizard recommends 8KB for vmware.

I've read that QCOW2 uses 64KB blocks? Does this mean I use 64KB on the iscsi 
LUN? Sorry if this is a stupid question.

Regards,
William

Re: [ovirt-users] Hosted engine already imported

[Jamie Lawrence]

Does anyone know the answer to the specific question below?  I'm not asking for 
workarounds to try;  that approach has repeatedly gone nowhere and time is 
becoming an issue for me. If I'm on the wrong track, I'd be happy to hear that, 
too. (Well, not happy, but that would at least be progress.)

- - - - 

I’m wondering if I can do this a different way. Since it is already imported, I 
can create VMs, and the only other warning I’m getting in the logs is 
unrelated, I’m thinking that the problem here is that something didn’t get 
properly set in the DB, and I should be able to fix that manually.

In looking at the code 
(https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/storage/domain/ImportHostedEngineStorageDomainCommand.java),
 it to my (not very deep) read that the setSucceeded call failed, even though 
AttachStorageDomainToPool worked.

 if (getSucceeded()) {
   AttachStorageDomainToPoolParameters attachSdParams =
   new AttachStorageDomainToPoolParameters(
   addSdParams.getStorageDomainId(),
   addSdParams.getStoragePoolId());
   setSucceeded(getBackend().runInternalAction(
   VdcActionType.AttachStorageDomainToPool,
   attachSdParams,
   getContext()).getSucceeded());
   }

   setActionReturnValue(heStorageDomain);

Is there a way to call setSucceeded without hacking together a custom utility? 
Not seeing it in vdsClient --help, which doesn’t surprise me. In looking over 
the stored procedures, I’m also not finding a likely candidate, but that is 
probably because there are so many that I’m just missing it.

Does anyone know what the relevant SP is, or in some other way clue me in on 
the right direction here?  

I realize this is not supposed to be the way to do things. But I’m not finding 
a better solution, and attempting to find a “right” way via questions to this 
isn’t working either. And of course I take full responsibility when Ovirt kills 
my pets and drinks all my liquor.

if it’s not successful there should be an event log message about that. And 
prior to taking the snapshot a warning in red at the bottom of the dialog (that 
check happens when you open the dialog, so it may not be 100% reliable)

if you want to doublecheck then this is noticable in vdsm.log. First we try to 
take the snapshot with fsfreeze, and only when it fails we take it again 
without it.

It’s a matter of Linux and Windows implementation, they both have an API 
supporting that at kernel level. I’m not aware of filesystem limitations.

Re: [ovirt-users] oVirt Hosted Engine Setup fails

[Manuel Luis Aznar]

Hello there,

Sorry for the delay to answer the mail, but, I have been busy doing
things...

The permission on /dev/random are the following:

[root@host1 manuel]# ls -la /dev/random
crw-rw-rw-. 1 root root 1, 8 may  4 18:06 /dev/random

Suppose that these permission should look something like:

[root@host1 manuel]# ls -la /dev/random
crw-rw-rw-. 1 vdsm kvm 1, 8 may  4 18:06 /dev/random

Finally I do not know what you meant with permission on SELinux audit
logs?¿? Sorry for my lack of understanding, so, please let me know much
more precisely and I will look for it


Thanks for all in advance
I will be waiting for you

 Hello there,

 I have been looking in the internet using google why my
 installation of ovirt-hosted-engine is failing.

 I have found this link:

 (Hosted engine install failed; vdsm upset about broker)

 It seems to be the same error...

 So to knarra and Jamie Lawrence my question is:

 Did you manage to discover the problem?? In my instalation I am
 using nfs and not gluster...

 I have read the error and is the same error "BrokerConnectionError:

I haven't seen it documented, oVirt/RHEV always had a full blown GUI, which
allowed for rightclicks, I normally try a rightclick in every UI that is
new to me. I suppose the fact that it's a web UI might have caused you to
believe a rightclick is irrelevant, and if that's the case, for product
maturity's sake, I'd suggest you post a bug in bugzilla to explicitly
document the possibility of rightclicking.

Maybe I'm old fashioned (or just plain out old), but I usually hold myself
back, no matter how annoyed I am, from taking such tones with people whom I
do not know and who are, moreover, trying to help me. But that's just me,
I'm not your father to teach you how to behave.

There is limited space "in plain sight", this is why there is the right
click menu available with all the options. Which buttons should be present
outside that menu is arguable, if you think "power off" should be there,
please open a BZ and provide your reasons.

Aha, so there is a hidden context menu with additional options..  THAT was
the key.  Thank you.  I was unaware of a right-click context menu for VMs
(or indeed anywhere in the webui).  Is this documented somewhere?

As for my tone, don't you think I had looked for a "power off" button? 
Your first reply was, while 100% correct, completely useless is helping. 
Of course I wanted power off; I couldn't find it.  THIS message, thank
you, provided what I needed.

I am very aware, thank you.  I've been running VMs since, oh, 1993.  My
last system was a vmware-based solution which I had in production for
about a decade.  (It had a "power off" button in plain sight, by the way).

I spent an hour trying various ways to gracefully shut the system down
before I emailed, but the VM was completely wedged, not responding to
keyboard or mouse events.  I tried soft reboot and soft shutdown to no
avail.  I tried sending Ctl-Alt-Del, to no avail...  Power Off is, of
course, a last resort, but I couldn't find the option (until you pointed
me to the right-click context menu, so again, thank you).  I'll note that
even a google for "ovirt power off guest" does not provide the hint about
the right-click context menu.

I can look into this, but I don't think it would help this situation; like
I said, the machine was completely wedged.  Also, the machine auto-logs-in
so there is always a "user", so again, probably not applicable to my
situation.

Thanks Again!!

While I do not appreciate your tone of conversation, I'll oblige, assuming
you haven't had your morning coffee yet. Right click the VM, the option is
right there. See the screenshot attached

Just so you are aware, power off pulls the plug out of the VM, it kills it
outright, so the effect will be just as if you've lost power to it. It is
generally healthier to solve the shutdown problem.

Here's a hint, this isn't about Windows 10, but might hit close the mark
nonetheless:

He was not making a joke, there should be a 'power off' button between the 
shutdown and reboot button. If it is not there, that is a problem. Is it also 
not there when you right click on the grid in the menu that pops up?

[ovirt-users] Info on live snapshot and agent interaction

[Gianluca Cecchi]

Hello,
supposing to have a Linux VM with ovirt-guest-agent installed, during a
live snapshot operation it should be freeze of filesystems.
Where to find confirmation of correct/successful interaction?
/var/log/messages or agent log or other kind of files?
Are there any limitations on filesystems that support freeze? Is it
fsfreeze the command executed at VM OS level or any other low level command?

Thanks,
Gianluca

Okay, I'll bite.  Which button is that?

I'm in the Virtual Machines tab on the admin portal; I select the hung VM
from my list and I see the following items at the top of the page:
"New VM", "Import", "Edit", "Remove", "Clone VM", "Run Once", "",
"", "", "", "", "Migrate", "Cancel
Migration", "Cancel Conversion", and then the right arrow to "Make
Template", "Export", "Create Snapshot", "Change CD", "Assign Tags", and
"Guide Me".

Please, kind sir, which one is the "power off" instead of "shutdown"?

[ovirt-users] Force-Shutdown a VM?

[Derek Atkins]

Hi,

I'm running ovirt-4.0.6 on EL7.3.

I've got a stuck VM (Windows 10) that I'm trying to restart.
Unfortunately it's "up" enough that ovirt is trying to perform a
soft-shutdown, but it's not up enough to complete the task.  If I login
to the ovirt admin portal as the admin, select shutdown, I see the
following engine log messages before I get an event "Shutdown of VM
 failed.":

So, how can I get out of this situation?  How can I force-powerdown this
VM so I can reboot it?

Thanks,

Re: [ovirt-users] VM Template Error

[Bryan Sockel]

I have been moving around my storage setup, and this storage domain does not 
exist in my environment anymore.  Not sure if this if this VM was created on 
this storage domain and then moved.  

I am attempting to create a template on a storage domain that does currently 
exist in my environment.  How would i remove the reference to this storage 
domain so it is not used?

According to the log the the storage domain (where the disk is stored is not 
exists)
StorageDomainDoesNotExist: Storage domain does not exist: 
(u'2de6ad97-1f33-41e5-b021-bacec14ce6e4',)

Does all the storage domain active in your data center?
Did you move the disk or remove and added a different storage domain?

Hi.  the vm does exist and is bootable.  The vm only has one disk and it is

yes, but the template’s copy of that disk somehow can’t be created. 
Perhaps share more of the vdsm logs to see why the image copy failed

its looks like vdsm complain that the image is not exists.
can you run the VM with no errors? (if the VM have more then one disk make 
sure that its exists and accessible).

if all good please attach the full vdsm and engine log.

once gluster hosts are added into the UI, user will be able to see

i'm not using a hyperconverged/self-hosted setup, my engine is

where
installed on top of centos7, not using oVirt Node.

does my setup make sense (it's only for testing)?
do i have to configure gluster hosts manually?

yes, you will have to do this manually .

Installing gluster packages have to done manually. Once gluster
packages
are installed you can create a gluster cluster from ovirt UI , add
gluster hosts and create volumes on them using the volumes tab.


i'm sorry, but i'm missing all these "Gluster Volumes" UI components
that are mentioned in
http://www.ovirt.org/develop/release-management/features/gluster/gluster-support/.


the tabs i see for my storage cluster are "General", "Logical

"Services" is
empty, is that a problem?

what's wrong?

thx

Does your cluster has both virt+gluster enabled or only virt ? If only
virt you will not be able to see them.

If the cluster has both virt+gluster service enabled or only gluster
service enabled you should be able to see them.


my storage cluster has only gluster service enabled

matthias



I think you have selected the cluster and you are referring to the sub
tabs for that cluster. There should be a main tab called 'Volumes' which
is present. Are you not seeing that? I have attached screenshot for the
same.



thanks for the screenshot, now i know how it should look like. i'm
attaching my screenshot. i'm missing a couple of elements, especially
"Cluster Node Type" (i don't have that in my VM cluster either). is
there an obvious explanation? next step would be to recreate the
gluster cluster with "clean" oVirt Nodes. maybe my storage hosts are
botched, i had glusterfs 3.10 packages installed on one of them
previously

thanks a lot so far
matthias


During the engine-setup when application mode was asked hope you have
set "Both" .



no, i didn't... (didn't know what i was doing then)
i'm learning it the hard way... going to start again from scratch...
still i think oVirt is a great product, thanks for software and support ;-)

Hi Jim,

You can try the taskcleaner script on dbutils.
For instance:
# PGPASSWORD={pass} ./taskcleaner.sh -u engine -d engine -t {disk,snapshot}
-z

I recommend you to check all the options available for it.

Cheers,
Gonza.-

once gluster hosts are added into the UI, user will be able to see

this you will need to create a new storage domain with the mount path

i'm not using a hyperconverged/self-hosted setup, my engine is

master domain. my hosts (for hypervisors and gluster storage) where 
installed on top of centos7, not using oVirt Node.


does my setup make sense (it's only for testing)?
do i have to configure gluster hosts manually?

yes, you will have to do this manually .
Installing gluster packages have to done manually. Once gluster packages 
are installed you can create a gluster cluster from ovirt UI , add 
gluster hosts and create volumes on them using the volumes tab.
do i need more than 2 storage hosts when i want to configure gluster 
with ovirt (in hyperconverged setup 3 hosts are mandatory)?
It is always recommended to have 3 hosts as we say that in replica 3 
volumes there is less / no chance to see split brain issues. For hyper 
converged setup 3 hosts are mandatory.
do i need oVirt Node/cockpit on the storage hosts to do further 
configuration?
you can reduce the pain of configuring gluster hosts manually if we 
cockpit on centos7 / Ovirt Node.

Please provide some more details. Was this setup upgraded from previous
versions? Which? What version is on the hosts (original and current)?

See these for some background:

http://www.ovirt.org/develop/release-management/features/engine/metrics-store/
https://bugzilla.redhat.com/showdependencytree.cgi?id=1402901_resolved=0

These are currently not strictly needed, unless you want to try this feature.
It's expected to be mandatory in 4.2. They are already installed automatically
for new 4.1 hosts.

Best,
