Thanks Michael for your response. Could you also please help in understanding
#1 On my ceph cluster , how can i confirm if journal is on block device partition or on file ? #2 Is it true that by default ceph-deploy creates journal on dedicated partition and data on another partition if i use the command ceph-deploy osd create ceph-node1:/dev/sdb I want to understand the concept of journals creation in Ceph. Hope you will help me. - vicky On Tue, Jun 9, 2015 at 5:28 PM, Michael Kuriger <[email protected]> wrote: > You could mount /dev/sdb to a filesystem, such as /ceph-disk, and then > do this: > ceph-deploy osd create ceph-node1:/ceph-disk > > Your journal would be a file doing it this way. > > > > [image: yp] > > > > Michael Kuriger > > Sr. Unix Systems Engineer > > * [email protected] |( 818-649-7235 > > From: Vickey Singh <[email protected]> > Date: Tuesday, June 9, 2015 at 12:21 AM > To: "[email protected]" <[email protected]> > Subject: [ceph-users] Beginners ceph journal question > > Hello Cephers > > Beginners question on Ceph Journals creation.
