Might not be quite what you're after but adding<br>

Hi there. Thanks for the reply.<br>
Yes I am aware of that and it seems that's what I will have to do.<br>
I have no problem with VDSM managing the file, I just wish it didn't automatically load local storage devices into multipathd.<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto">It doesn't.

I'm still not clear on the purpose of this automatic management though.<br>
>From what I can tell there is no difference to hosts/clusters made through this automatic management - i.e. you still have to add storage domains manually in oVirt.<br>
<br>
Could anyone give any info on the purpose of this auto-management of local storage devices into multipathd in VDSM?<br>
Then I will be able to make an informed decision as to the benefit of letting it continue.<br>
<br>
Thanks, Ben<br>

Hi All<br>
<br>
I have been running ovirt in a lab environment on CentOS 7 for<br>
several months but have only just got around to really testing things.<br>
I understand that VDSM manages multipath.conf and I understand that<br>
I can make changes to that file and set it to private to prevent<br>
VDSM making further changes.<br>
<br>
I don't mind VDSM managing the file but is it possible to set to<br>
prevent local devices being automatically added to multipathd?<br>
<br>
Many times I have had to flush local devices from multipath when<br>
they are added/removed or re-partitioned or the system is rebooted.<br>
It doesn't even look like oVirt does anything with these devices<br>
once they are setup in multipathd.<br>
<br>
I'm assuming it's the VDSM additions to multipath that are causing<br>
this. Can anyone else confirm this?<br>
<br>
Is there a way to prevent new or local devices being added<br>
automatically?<br>
<br>
Regards<br>
Ben<br>
