[ovirt-users] NFS 4.1 support and migration

[spfma.tech at e.mail.fr]

As I thought, the GUI didn't allow me to put the domain she depends on in maintenance, so the engine domain wil stay in v3 for now. Maybe I should delete the engine vm, recreate it with new NFS options and then restore the last backup ? I may try this later.
   For the other domains, auto negociation of NFS settings worked and they are now all mounted using 4.1 version.

 Have to admit that I didn't play with the hosted engine thing, but maybe you can find the answers in the documentation:

 Thanks, I totally missed that :-/
   And this wil also work for the hosted engine dedicated domain, putting the storage domain the virtual machine is depending on in maintenance ?

 You can edit the storage domain setting after the storage domain deactivated (entered to maintenance mode).

In fact I don't really know how to change storage domains setttings (like nfs version or export path, ...), if it is only possible. 

I thought they could be disabled after stopping all related VMS, and maybe settings panel would then unlock ? 

But this should be impossible with hosted engine dedicated storage domain as it is required for the GUI itself. 

So I am stuck.

 I am not sure what you mean, Can you please try to explain what is the difference between "VMs domain" to "hosted storage domain" according to you?   Thanks,

 Thanks for your answer.
   And to use V4.1 instead of V3 on a domain, do I just have to disconnect it and change its settings ? Seems to be easy to do with VMs domains, but how to do it with hosted storage domain ?   Regards
