Might not be quite what you're after but adding

Hi there. Thanks for the reply.
Yes I am aware of that and it seems that's what I will have to do.
I have no problem with VDSM managing the file, I just wish it didn't
automatically load local storage devices into multipathd.
I'm still not clear on the purpose of this automatic management though.
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.
Could anyone give any info on the purpose of this auto-management of
local storage devices into multipathd in VDSM?
Then I will be able to make an informed decision as to the benefit of
letting it continue.
Thanks, Ben

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