Thanks you, Dan From: ceph-users [mailto:ceph-users-boun...@lists.ceph.com] On Behalf Of Michal Chybowski Sent: Thursday, December 17, 2015 2:28 PM To: ceph-users@lists.ceph.com Subject: Re: [ceph-users] data partition and journal on same disk Or, if You have already set partitions, You can do it with this command: ceph-deploy osd prepare machine:/dev/sdb1:/dev/sdb2 where /dev/sdb1 is Your data partition and /dev/sdb2 is Your journal one.
