Can you please check the iso NFS export ACL as described here [1]?
If you created it via engine setup, now by default only engine host can access 
it so if you want to access it from other hosts you have to extend that ACL.
If it not enough please check also the firewall rules.

The Python SDK only supports "Basic" authentication. Version 3.6 will
also support Kerberos authentication. There are no plans at the moment
to support any other authentication mechanism in the Python SDK.

Re: [ovirt-users] VMs unknown state and ovirt node Non Responsive

The actual problem is that there is no way to tell the oVirt engine to
use a protocol other than SSLv3 to communicate with hosts. That has been
fixed in version 3.5:

  http://gerrit.ovirt.org/34917

Given that this is an important security issue I'd expect to see it
fixed in 3.4.z as well. While/if that doesn't happen then your only
alternative to fix properly the issue is to upgrade to 3.5 and then make
sure that the VdsmSSLProtocol configuration parameter is set to TLSv1.

[ovirt-users] Does my Storage Domain crashed or is this iSCSI LUN's a problem?

2015-01-26 Thread shimano 
Hi guys,

I'm trying to run one of my storage domains, which experienced failure.
Unfortunately, I meet a very nasty error (Storage domain does not exist).

Could someone tell me, how to try to restore this domain?

P.S.
It's an oVirt 3.4.2-1.el6

The "supported" method of achieving this is to place "# RHEV PRIVATE" in
the second line of your hand-modified multipath.conf

I do not understand why this has happened only after upgrade to 3.5.1 -
3.5.0's should have reverted you multipath.conf just as well during each
vdsm startup.

The good thing is that this annoying behavior has been dropped from the
master branch, so that 3.6 is not going to have it. Vdsm is not to mess
with other services config file while it is running. The logic moved to
`vdsm-tool configure`

I think what happened is:

1. 3.5.1 had new multipath version
2. So vdsm upgraded the local file
3. blacklist above was removed
   (it should exists in /etc/multipath.bak)

To prevent local changes, you have to mark the file as private
as Dan suggests.

Seems to be related to the find_multiapth = "yes" bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1173290

Ben, can you confirm that this is the same issue?

Re: [ovirt-users] Loopback interface has huge network transctions

2015-01-26 Thread Martin Pavlík 
Hi Punit,

it is ok since ovirt-engine is using loopback for its purposes, e.g. postgress 
databas access. Try to check netstat -putna | grep 127.0.0 to see how many 
things are attached to it.

If you are interested in checking what is going on a bit more have a look @ 
this great how-to

Sorry for the late review; I have a couple of questions/comments.
- What do you mean by "VDI use cases" in the "Benefit to oVirt sanpshot"
  section?
  Do you refer to hosting services who would like to charge their
  customers based on actual bandwidth usage?
- I've added another motivation: currently-reported rxRate/txRate
  can be utterly meaningless.


I don't see reference to nasty negative flows: what happens if a host
disappears? Or a VM? I suppose there's always a chance that some traffic
would go unaccounted for. But do you expect to extract this information
somehow? Either way, it should be mentioned as a caveat on the feature
page.

The symptoms above sound exactly liek this issue.
When find_multipahts is no (the default when the directive is not present)
I sthat all non-blacklisted devices are tried to get claimed, and this happened 
above.

Blacklisting the devices works, or adding "find_mutlipaths yes" should also 
work, because
in that case only device which have more than one path (or are explicitly 
named) will be
claimed by multipath.

My 2ct.

[ovirt-users] Loopback interface has huge network

2015-01-26 Thread Nikolai Sednev 
is ok since ovirt-engine is using loopback for its purposes, e.g. postgress 
databas access. Try to check netstat -putna | grep 127.0.0 to see how many 
things are attached to it. 

If you are interested in checking what is going on a bit more have a look @ 
this great how-to

Re: [ovirt-users] iso uploader times out

2015-01-26 Thread Mikola Rose 
Here is my export,  it appears that this is correct;

/Volumes/Raid1  *(rw,anonuid=36,anongid=36,all_squash)

This is the entry point to the iso folder i created on the NFS

The one I created during setup is listed as unattached.  If I try and attach it 
is says there are no storage centre's to which the Storage Domain can be 
attached.

Hi list members,

Just finished deploying a self hosted engine. But i am having a problem
uploading an iso. It seems to be timing out..

engine-iso-uploader -i iso upload rhel-server-6.6-x86_64-dvd.iso
Please provide the REST API password for the admin@internal oVirt Engine user
(CTRL+D to abort):
Uploading, please wait...
ERROR: mount.nfs: Connection timed out

I am a little confused as the host machine has access to the NFS shares but
the engine vm does not yet I have created an iso storage item successfully
so the engine can see the nfs share?

Any idea on how I can trouble shoot this?

Can you please check the iso NFS export ACL as described here [1]?
If you created it via engine setup, now by default only engine host can access 
it so if you want to access it from other hosts you have to extend that ACL.
If it not enough please check also the firewall rules.

I would like to point out one issue.  Once a device is claimed (even if
find_multipaths wasn't set when it was claimed) it will get added to
/etc/multipath/wwids.  This means that if you have previously claimed a
single path device, adding "find_multipaths yes" won't stop that device
from being claimed in the fulture (since it is in the wwids file). You
would need to either run:

# multipath -w 

to remove the device's wwid from the wwids file, or run

# multipath -W

to reset the wwids file to only include the wwids of the current
multipath devices (Obviously, you need to remove any devices that you
don't want multipathed before your run this).

Re: [ovirt-users] iso uploader times out

2015-01-26 Thread Mikola Rose 
I am going to redeploy yet again...
Quick question though,  when the hosted-engine deployment asks what interface 
to use for management what network should this be since the host has 2 nics

192.168.0.0/32  is our general network
192.168.1.0/32  is for the NFS and inter vm traffic

I would assume it would be 192.168.1.0 ?

what do you mean with "new multipath version"?
I currently have device-mapper-multipath-0.4.9-56.fc20.x86_64
The system came from f18 to f19 and then to f20 via fedup in both cases
In my yum.log files I see this about January 2013 when I was in Fedora 18
Jan 07 00:11:44 Installed: device-mapper-multipath-0.4.9-36.fc18.x86_64

I then upgraded to f19 on 24th November 2013 and device-mapper-multipath
was the one pushed during the fedup update:
device-mapper-multipath-libs-0.4.9-51.fc19.x86_64

Then on 12th of November 2014 I passed form f19 to f20 and fedup pushed
device-mapper-multipath-0.4.9-56.fc20.x86_64
that is my current version
At that time I also passed from oVirt 3.4.4 to 3.5.0.
And I didn't register any problem with my internal disk

It was sufficient to keep inside
blacklist {
   devnode "sd[a-b]"
}

At the head of the file I only had:
# RHEV REVISION 1.0

No reference about
# RHEV PRIVATE

But right now that I'm writing I notice that my rule for blacklist after
migration to 3.5.1 was

devnode "^(sda|sdb)[0-9]*"

probably blacklists only partitions and not the full disks ;-)
So I'm going to check with the old blacklist option and/or the PRIVATE
label as suggested by Dan...

Probably passing from RHEV REVISION 1.0 to 1.1 the original blacklist part
was thrown away...

2. So vdsm upgraded the local file

It seems it didn't generate any multipath.conf.bak ...

Hi Tim,

We should share the official iso this week.

Meanwhile, if you are interested in give a try on our jenkins jobs:
