Hi all,

I'm trying to install a ceph cluster with one SSD sda (running the system on 
sda1) sda2 is for swap and my OSD (I have only one OSD per node...) will be sdb 
which is not an SSD but a 7200rpm disk.
I want to use sda3 for my journal (so I want to set my journal on my ssd).
Ceph-deploy osd create -fs-type btrfs host1:sdb:sda3   doesn't work.
I'm trying to guess why... and editing /usr/sbin/ceph-disk (line 804) :

If is_partition(journal):
                LOG.debug('Journal is a partition')
                LOG.warning('Will not be hot-swappable etc')
                Return(journal, None, None)

So nothing seems to be made if a partition is found.
I have only OSD/per node so I need only one partition for my journal or am I 
wrong ?


Regards,
