Hello,
I've a question regarding Master Storage Domain. I did already search the
net without results so I'm asking here.
In our production setup (ovirt 4.1.7) we have five iSCSI Data Storage
Domains and we unfortunately need to remove the one that is the Master SD.
That's not difficult, I know the procedure as I did it in the past:
- Move every disk belonging to the MSD to another SD
- Put the MSD in maintenance
- Detach it then Remove it
Another SD is automatically selected as Master and everything should be OK
(for the sake of simplicity i did not mention the other operations needed
on the storage array and the hosts to phisically remove the LUN).
The tricky part is I don't want a random choice, I want to choose which SD
becomes the new Master.
Is there any specific procedure to obtain this result?
TIA,
Giorgio.

In that case move other SD to maintenance only the SD which you want to be
MSD keep Active.Then once you move your present MSD to maintenance, active
one will be MSD.

Hi,
I'm sorry to say your suggestion is infeasible. This is a production
environment and I'm unable to put in maintenance any SD apart the one I
want to shutdown.
I was hoping there is some weighting mechanism to affect the choice of the
MSD but I didn't have the time to look at the algorithm that makes that
choice.
Thank you anyway,
Giorgio.
