[ovirt-users] ovirt 3.6.7 and gluster 3.7.14

2016-08-07 Thread Luiz Claudio Prazeres Goncalves
Hi, it seems the ovirt-3.6-dependencies.repo is pointing the yum repo to
http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-$releasever/$basearch/
and
http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-$releasever/noarch,
however the "LATEST" is now pointing to gluster 3.8.x and not to 3.7.x
anymore.

So, in order to fix it I was forced to manually adjust the yum repo paths
as you can see below.  Is this procedure correct? I would say yes, but it's
always good to double check :)

Also, It's currently running centos 7.2 + ovirt 3.6.6 + gluster 3.7.11
(client) and I'm planning to upgrade to ovirt 3.6.7 and gluster 3.7.14
(client).

The oVirt Cluster is running on top of an external gluster replica 3
cluster, hosting the engine storage domain and vms storage domain, running
the version 3.7.11 which I'm also planning to move to 3.7.14 as well.  I'm
using XFS and not ZFS, which seems to have issues with gluster 3.7.13

Is this upgrade safe and recommended?

Thanks
-Luiz

Re: [ovirt-users] oVirt 4.0 Hosted Engine

Hi,

Thanks for your help...

The scheduling policy is set to none
I've set the "Enable HA Reservation" property and also install the 
macspoof hook and power management is configured correctly and seems to 
work but all that didn't help .


Regargs,

Arsène

and that it has power management enabled.

I've tried to redeploy the host using the GUI when editing the
Host and set DEPLOY at Hosted Engine but in that case the Event

Is there a way to check if the host is registered as hosted-engine

How could I register it correctly?

Let me know if you need any logs.

 No, I meant the 'Host' column in the Virtual Machines tab but if you
 see
 the VMs in the "Virtual machines" sub-tab of the host then run_on_vds
 points to the right host..

 The host is up in the webadmin as well?
 Can you share the engine log?

 Yes, the host is up in the webadmin, there are no issues with it, just

Neither should touch the qemu process, but re-connect to it as they
restart.

[ovirt-users] oVirt 4.0 Hosted Engine

2016-08-07 Thread Arsène Gschwind

Hi,

I have an oVirt setup with 2 server using hosted-engine, both server 
resgistered properly the hosted-engine using :

# hosted-engine --deploy

but for some reason the second isn't recognized as a host for 
hosted-engine and I'm not able to migrate the hosted-engine.

The error I get when trying to migrate:

 * Cannot migrate VM. There is no host that satisfies current
   scheduling constraints. See below for details:
 * The host xx did not satisfy internal filter HA because it is not
   a Hosted Engine host..

I've tried to redeploy the hosted-engine but this will fail since the 
host already exists in the management DB.
I've tried to redeploy the host using the GUI when editing the Host and 
set DEPLOY at Hosted Engine but in that case the Event just says the 
configuration was updated but nothing happens.


Is there a way to check if the host is registered as hosted-engine host?
How could I register it correctly?

Re: [ovirt-users] preallocated storage issue?

2016-08-07 Thread Fred Rolland
Simon,

What is happening is that when we create a preallocated disk on NFS, we
fill the file with zeros in order to "allocate" the space.
However, while copying the disk we use qemu-img that will ignore the zeros.

Quick way to demonstrate:

[root@white-vdsd test]# dd if=/dev/zero of=myfile.txt bs=1M count=1
1+0 records in
1+0 records out
1048576 bytes (1.0 MB, 1.0 MiB) copied, 0.00172084 s, 609 MB/s

[root@white-vdsd test]# du -h myfile.txt
1.0Mmyfile.txt

[root@white-vdsd test]# ls -lh myfile.txt
-rw-r--r-- 1 root root 1.0M Aug  7 12:39 myfile.txt

[root@white-vdsd test]# qemu-img convert myfile.txt myfile2.txt

[root@white-vdsd test]# ls -lh myfile2.txt
-rw-r--r-- 1 root root 1.0M Aug  7 12:41 myfile2.txt

[root@white-vdsd test]# du -h myfile2.txt
0myfile2.txt

[root@white-vdsd test]# qemu-img info myfile.txt
image: myfile.txt
file format: raw
virtual size: 1.0M (1048576 bytes)
disk size: 1.0M

[root@white-vdsd test]# qemu-img info myfile2.txt
image: myfile2.txt
file format: raw
virtual size: 1.0M (1048576 bytes)
disk size: 0

I hope this explains what you see.

Regards,
Fred

oVirt still lists the disk as preallocated in the GUI but it is in fact thin 
provisioned.

I see the same issue if I clone a preallocated VM. The size on disk ends up 
being the equivalent of a thin-provisioned disk. I also had the issue when 
importing VM’s from an export domain when I had selected preallocated in the 
import dialog box.

Is this a known issue? Should preallocated not mean preallocated on physical 
disk?

Ovirt Engine is running 3.6.4.1-1.el6

The ovirt nodes are running:

OS Version:RHEL - 7 - 2.1511.el7.centos.2.10
Kernel Version: 3.10.0 - 327.4.5.el7.x86_64
KVM Version:2.3.0 - 31.el7_2.7.1
LIBVIRT Version:   libvirt-1.2.17-13.el7_2.2
VDSM Version: vdsm-4.17.23.2-0.el7.centos
SPICE Version:  0.12.4 - 15.el7
GlusterFS Version:   [N/A]
CEPH Version:   librbd1-0.80.7-3.el7

Many thanks,

Simon

Re: [ovirt-users] preallocated storage issue?

2016-08-07 Thread Fred Rolland
Simon hi,

What storage type are you using in source and target storage domains ?
(NFS, ISCSI)

Can you share the logs?

Thanks,
Fred

Not in the short term roadmap.
Of course, patches are welcome. It's mainly in VDSM.
I wonder if it'll work in NFS.
