the pool "needs a master domain". if one doesn't exist, it is re-created.
this should hopefully go away in 3.6.

Hi Zenon,

Renaming a host is possible in ovirt by clicking on the edit button 
. AFAIK, IP address of a host which is added to ovirt web manager cannot 
be changed, it has to be added as a new host to the web manager.

Re: [ovirt-users] Can and How to move a VM from VMware to oVirt

Hi,

I want to move a windows VM(managed by VMware Player in Windows7 host)

Thanks.

This is the procedure I've used several times from ESXi, should be the 
same with any vmdk.


Shutdown guest on ESXi  (or use GhettoVCB to make a snapshot backup if you 
don’t want an outtage)
NFS copy guest from ESXi server to temp storage somewhere
qemu-img convert guest.vmdk -O raw guest.raw
Create an oVirt guest with the appropriate OS type
Add a disk of the same GB to the guest
After oVirt finishes creating the disk, copy the guest.raw file over the disk 
image oVirt made
boot guest and install qemu-agent, ovirt-agent, spice-agent (or better yet, do 
this before you shutdown on ESXi)
remove VMware tools.

We have several oVirt setups, and we can not change that.
We have several VMs on each of them, and sometimes, we have to access
their oVirt VNC console, but it is painful to know on which oVirt they
are running. At present, I either have to remember on which one it lies,
or to web-connect on every oVirt web GUI and crawl.


you can script that using REST or python sdk.

short algo (might miss some steps!):
1. crawl all engines for your vms
2. save the engine which is managing this specific vm
3. connect to the vm through novnc/whatever via ticket to this
engine

this should take not that much time :)

or look at manageiq which can be used to manage VMs across multiple

you can set the VM to use the host cpu (it won't be migratable, but you

Re: [ovirt-users] Cannot activate storage domain

[SATHEESARAN]

Hi Brent,

From your logs, I could able to see that gluster mount has become 
read-only.

This happens only two circumstances,
1. Client-side quorum is enabled on that volume and its not met
2. Client-side quorum is enabled on that volume and the first brick of 
the replica pair went down.


I think you would have met the second scenario.
Client-side quorum is enabled on gluster volume to prevent network 
partition problems which would lead to split-brain scenarios.
If you want to restore your storage domain, you can disable client-side 
quorum momentarily using RHEVM UI

or using gluster cli. ( # gluster volume reset  quorum-type )

Hope that helps.

Hello,

I had actually gotten this sorted out, somewhat. If I disable server

added to the volume through oVirt however, it appears that it may

The recommended setting is to have both client and server side quorum 
turned on. But turning on server-side quorum with a 2-way replica 
volume would mean that your volume goes offline when one of the bricks 
goes down.


"gluster volume info" command will give you information about the 
volume topology. So will the bricks sub-tab for Volume in oVirt. The 
order in which the bricks are listed, is the order of the replica sets.


Disabling quorum allowed me to get the VM's affected back online 
however, is
this the recommended procedure? I tried to use replace-brick with 
another

node but it failed because the failed brick was not available. Would we
leave quorum disabled until that brick gets replaced? IE - rebuild the
server with the same hostname/IP file structure and rebalance the 
cluster?


http://www.gluster.org/community/documentation/index.php/Virt-store-usecase 
- for recommendations on volume tunables.


You could add another brick to your volume to make it a replica 3 and 
then turn on quorum?


For help on recovering your volume, I suggest you write to 
gluster-us...@gluster.org







While that happened, I read somewhere about this happening with a 
replica 2
- I've created a new volume with replica 3 and plan to test this 
again. Is
there any info you can point me to for how to handle this when it 
happens or

what the correct procedure is when a "first" brick fails?

Have the following:



6 hosts - virt + Gluster shared



Gluster volume is distributed-replicate - replica 2



Shutting down servers one at a time all work except for 1 brick. If
we shut down one specific brick (1 brick per host) - we're unable to
activate the storage domain. VM's that were actively running from
other bricks continue to run. Whatever was running form that specific
brick fails to run, gets paused etc.



Error log shows the entry below. I'm not certain what it's saying is
read only.nothing is read only that I can find.

According to Ovirt/Gluster, if a brick goes down, the VM should be
able to be restarted from another brick without issue. This does not
appear to be the case. If we take other bricks offline, it appears to

work as expected.

Something with this specific brick cases everything to break which
then makes any VM's that were running from the brick unable to start.
Do you have the recommended options for using volume as virt store 
turned
on? Is client-side quorum turned on for the volume? Is the brick that 
causes

the issue, the first brick in the replica set?

[ovirt-users] Two new plugins for oVirt

[Lucas Vandroux]

Dear all,


We developed 2 new plugins for the oVirt-Engine.


The first one is to interact with the engine-manage-domains tool directly from 
WebAdmin: https://github.com/ovirt-china/manage-domains-plugin


The second one is to schedule automatic backups of your vms: 
https://github.com/ovirt-china/vm-backup-scheduler


Maybe they can help you.

Hi Julian,

It is not clear what are you trying to do - is this lv on shared storage, and 
accessed
by multiple hosts or use only one host?

If the lv is shared, you cannot create a file system and mount it on multiple 
hosts (unless you
are using cluster file system).

If this local storage for one host, you should create a file system and mount 
it, and then
you can use the mountpoint as local storage.

Please describe in details what are you trying to do and how did you create the 
storage
domain in the engine side.
