Re: [ovirt-users] imageio: Error setting ImageProxyAddress's value. No such entry with version general.

[Daniel Erez]

Hi Richard,

This issue has been already addressed by
https://bugzilla.redhat.com/show_bug.cgi?id=1476979
The fix should be in latest build (4.1.5.1).
Alternatively, you can also amend it manually in the DB if you prefer to
avoid updating

Re: [ovirt-users] hosted engine setup with Gluster fail

[Kasturi Narra]

can you please check if you have any additional disk in the system? If you
have additional disk in the system other than the disk which is being used
for root partition then you could specify the disk in the cockpit UI (i
hope you are using cockpit UI to do the installation) with no partitions on
that. That will take care of the installation and make your life easier as
cockpit + gdeploy would take care of configuring gluster bricks and volumes
for you.

Re: [ovirt-users] hosted engine setup with Gluster fail

Dear Nara,

 

All the partitions, pv and vg are created automatically during the initial 
setup time.

If the above step is complicated, can you please suggest to setup glusterfs 
datastore in ovirt

May i know how these vgs are created ? If they are not created using gdeploy 
then you will have to create bricks manually from the new vg you have created.

Re: [ovirt-users] Question on Datacenters / clusters / data domains

[Shani Leviim]

Hi Eduardo,
Welcome aboard!

First, you may find some relevant information in here: http://www.ovirt.org/
documentation/admin-guide/administration-guide/ .

Regarding your questions:
* A data domain in an oVirt Data Center must be available to every Host on
the Data Center: Am I right?
Yes, you're right.

* Can I manually migrate VMs between Datacenters?
VM migration can't be performed between data canters, so you can't use the
'migrate VM' function.
In order to "migrate" your VM between different data canters, you can use
'export' and 'import' functions and an 'export domain':
By creating an export domain for one of your DC's (each DC can have up to
one export domain), and exporting your VM to that storage domain,
you can then detach the export domain from that DC and attach it to the
other DC, and by importing there your VM you'll finish the transaction.

Another option is to detach the VM's storage domain from one DC and attach
it the second one.
That way you'll move the whole storage domain between your DCs.

If you have any further questions, don't hesitate to ask :)


*Regards,*

*Shani Leviim*

Re: [ovirt-users] hosted engine setup with Gluster fail

Dear Nara,

 

Thank you for your great reply.

 

1) can you please check if the disks what would be used for brick creation does 
not have labels or any partitions on them ?

 

Yes I agreed there is no labels partition available, my doubt is it possible to 
create required bricks partition from available 406.7G  Linux LVM. Following 
are the physical volume and volume group information.

 

 

[root@ovirtnode1 ~]# pvdisplay 

  --- Physical volume ---

  PV Name   /dev/sda3

  VG Name   onn

  Total PE  142267

  Free PE   3823

  Free  PE / Size   3823 / 14.93 GiB

  VG UUID   nFfNXN-DcJt-bX1Q-UQ2U-07J5-ceT3-ULFtcy

   

 

I am thinking, to reduce the vg size and create new vg for gluster. Is it a 
good thinking.

Subject: Re: [ovirt-users] hosted engine setup with Gluster fail

 

Hi,

 

   If i understand right gdeploy script is failing at [1]. There could be two 
possible reasons why that would fail.

 

1) can you please check if the disks what would be used for brick creation does 
not have lables or any partitions on them ?

 

2) can you please check if the path [1] exists. If it does not can you please 
change the path of the script in gdeploy.conf file to 
/usr/share/gdeploy/scripts/grafton-sanity-check.sh

 

[1] /usr/share/ansible/gdeploy/scripts/grafton-sanity-check.sh

 

Thanks

In 4.1, engine-backup has new options during restore:
'--he-remove-storage-vm' and '--he-remove-hosts'. Check '--help'. Sadly, we
do not have enough documentation for this. This is worked on, I hope to
have updates soon.

Best,

 As I recall (a few weeks ago now) it was after restore, once the host
 had been registered in the Manager. However, I was testing on 4.0, so maybe
 the behaviour is slightly different in 4.1.

 Can you see anything in the Engine or vdsm logs as to why it won't
 remove the storage? Perhaps try removing the stale HostedEngine VM ?
