Hi,
i'm a little bit surprised. I read through the new manuals of 0.77
(http://eu.ceph.com/docs/v0.77/start/quick-ceph-deploy/)
In the section of creating the osd the manual says:
/Then, from your admin node, use //ceph-deploy//to prepare the OSDs./
//
/ceph-deploy osd prepare {ceph-node}:/path/to/directory/
//
/For example:/
//
/ceph-deploy osd prepare node2:/var/local/osd0 node3:/var/local/osd1/
//
/Finally, activate the OSDs./
//
/ceph-deploy osd activate {ceph-node}:/path/to/directory/
//
/For example:/
//
/ceph-deploy osd activate node2:/var/local/osd0 node3:/var/local/osd1/
In former versions the osd was created like:
/ceph-deploy -v --overwrite-conf osd --fs-type btrfs prepare
bd-0:/dev/sdb:/dev/sda5/
^^^^^^^^^^ Journal
As i remember defining and creating a journal for each osd was a must.
So the question is: Are Journals obsolet now ?
