Fumble fingered accidental send...

Subject: gluster and multipath
Hi,
Just got very confused trying to add create an additional brick on my glust=
er node (I had created one yesterday and all was fine0
I had already created a partition on my /dev/sdb called sdb1
But when I tried mkfs.xfs (I am using xfs as that was in the example I was=
following - if LVM or something else would be better I am open to suggesti=
ons!)
It said /dev/sdb1 no such file or directory - which confused me as this wor=
ked yesterday.
I deleted the partition recreated it and tried and then it said that the de=
vice was busy.
It appears that multipathd is the culprit... but what I am struggling with =
is why it worked yesterday?? I may have created the partition before I pus=
hed the gluster install to it from the ovirt-engine? And does that install=
multipathd and it is now grabbing my devices? It is the only thing I can =
think of.
And if that is the case - I guess I have to blacklist these devices in mult=
ipath.conf while I create the partitions? And reboot and then remove the b=
lacklist and reboot - seems a bit clunky, is there a better way to add part=
itions and bricks?
Or I am just in a vortex wormhole of misunderstanding and grasping at stars=
to try and pull myself out ?
Thankyou for any advice - especially as this may not be so ovirt or a quest=
ion, but it's what I am working on.
