Re: [ovirt-users] deprecating export domain?

2017-10-02 Thread shubham dubey

Yes, I just gave an example case. If you want to use vms with a backup,
then you can just copy that vm or disk into another domain and make it as
backup domain as you do it in export domain.
In simple language, main aim of creating backup domain is just to use all
the features available in export domain without creating a dedicated export
domain.
Hope you understand now:)

Re: [ovirt-users] deprecating export domain?

2017-10-02 Thread shubham dubey

Hi,
The backup storage domain is quite like export storage domain but with easy
usability.
Since you can change any data domain into backup domain any time, you not
need to create a dedicated
export storage domain for backup or disaster recovery purpose. Altough its
working is same as export sd.

The process of backup can be as simple as this:
1) turn off all the vms in your storage domain
2) select backup flag to convert that into backup domain.

Once the domain is used for backup, you cannot make any changes to its vms,
disk etc as mentioned by maor.
And yes, you can convert export sd to data domain using cli script but it
is not required anymore.

If in future export storage domain get deprecated, you not need to be worry
about that much since you can convert all your
export sd into data domain anytime and start using backup feature instead.

Regards,
Shubham

[ovirt-users] Regarding wiki on Backup Storage

2017-06-04 Thread shubham dubey

Hello,

I just have put a PR for wiki on Backup Storage at ovirt-site[1].
The idea is to have a better backup solution for disaster recovery, in
place of export storage domain. The idea is already discussed in mailing
list earlier. Me and maor(as mentor) are working on this feature and till
now I have done a push[2] for adding backup flag in database.

I will appreciate everyone to review the wiki and share some
feedback/comments about our implementation process.

Re: [ovirt-users] Building oVirt engine on Debian

2017-05-26 Thread shubham dubey

 I have forgotten that you are doing it in debian. Maybe in case of debian
the error can there for some other reason so I leave it for others to
answer. But one more thing you can try is to decrease your swappiness value
to 10. If you have enough ram then this will at least make your system
freeze less.

Re: [ovirt-users] Error in attaching export storage domain

2017-05-21 Thread shubham dubey

Thanks for reply, I am not sure about how to mount the storage domain
manually.
But I have run the nfs-check and it gives no error.

One more thing I want to add is there are another sd also on the same host
which are connected to another dc ,so is this can be a problem in anyway?

Hello,
I have installed ovirt engine from source and installed all other required
packages also,
including ovirt-js-dependencies.But when I am login to the admin account I
am getting blank
page everytime. Some other pages are also coming empty sometime.
I have pasted the logs for
$HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py
start[1].The possible error log is

Re: [ovirt-users] Error in starting vdsm in host

2017-04-07 Thread shubham dubey

did I need to install it on the ovirt-engine machine?
Recently I have created the first host for my new ovirt setup.But when I
try to do initialize the host
it was getting failed.So, I think I need to first configure the vdsm in the
host.

I tried "vdsm-tool configure" it is giving me this error.
[root@localhost ~]# vdsm-tool configure

Checking configuration status...
lvm is configured for vdsm
libvirt is already configured for vdsm
FAILED: conflicting vdsm and libvirt-qemu tls configuration.
vdsm.conf with ssl=False requires the following changes:
libvirtd.conf: listen_tcp=1, auth_tcp="none", listen_tls=0
 qemu.conf: spice_tls=0.
Error:  Configuration of libvirt is invalid

I have changed those values in libvirtd.conf but still getting this same
error.

[ovirt-users] ovirt Node Building

2017-03-23 Thread shubham dubey

Hello,
I have recently build ovirt-engine from source using this link(
http://www.ovirt.org/develop/developer-guide/engine/engine-development-environment/).
Now I want to build ovirt node using this(
http://www.ovirt.org/develop/projects/node/building/). I am confused that
can I build that node on the same system as of ovirt-engine or I need to do
these steps on any other system.

Thanks,
Shubham

Hello,
I am interested in being part of ovirt for gsoc 2017.
I have looked into ovirt project ideas and the project that I find
most suitable
is Configuring the backup storage in ovirt.

Since the ovirt online docs have sufficient info for getting started for
development so I don't have a questions about that but I want to clarify
one doubt that did the previous year mentioned project on ovirt gsoc page
are also available to work on?
I will also appreciate any discussion about the project or question from
mentor side.Even some guideline for start working is welcome.

Thanks,
Shubham
