[ovirt-users] Migrate engine from one storage domain to another

[anton . louw]

Hi All,

What would be the easiest way to migrate my hosted engine disk from one storage 
domain, to another? I see that I can click on the disk, and select move, but 
for some reason I feel nervous about it :) 

Thanks

Hi Eric,

Can you try the following:
1. Set the node in maintenance
2. From the Hosts section ->  Installation -> Reinstall
3. Fill in if the host is hosting the HostedEngine and the rest of the wizard  
4.  Start the install
5. If it succeeds  -> remove the maintenance

No,  both first disk and second disk dedicated to that VM

Hi Gianluca,
I'm working on master 4.4 and I didn't run into this one.

Was the second disk shareable?
In the case of editing a shareable disk, you first need to shut down all
the VMs that disk attached to.

Also, editing the VM attached disks should accrue one by one, as you can't
edit them both at once (the edit button should be grayed out).

For a deeper look, can you please attach screenshots and UI+engine logs?


*Regards,*

Followed the instructions and it does work :-)

But I also tested if I could setup a hosted engine but that fails.
Should that work too but did I make a mistake or is that part not ready yet?

If it should work I can try again and upload logs if needed.

[ovirt-users] strange error when editing multiple disks

[Gianluca Cecchi]

I'm noticing this on 4.3.8 and I don't have understood exactly the raising
condition, if UI based or what
At first I thought it was the bootable flag, but it is not, apparently

vm1 powered on with two disks
I select the VM then Disks subtab
select line of second disk --> edit --> OK
All goes well
Then, remaining in the same Disks subtab window  I select the line of the
first disk --> Edit --> OK
And now I get the error window:
"
Error while executing action:

vm1:

   - Cannot edit Virtual Disk. At least one of the VMs is not down.

"
?
Then I go and select another powered on VM, vm2, with only one disk, the
one with bootable flag, and I'm able to edit it successfully.
Then I come back and select vm1 and Disks subtab, select again the first
line of the boot disk --> Edit --> OK
and I'm able to edit with success. but eg if I want to modify both
alias and description fields I have to do one at a time, otherwise if in
the same window I try to modify both and then press OK I still get the
error message above.

Can anyone verify/test? I was able to reproduce on bot oVirt 4.3.8 and RHV
4.3.8
