Re: switching journal location

Hi Tom,

you will have to stop the OSD, flush the existing journal to ensure data consistency at the OSD level and then switch over to the new journal location (initialise journal then start the OSD).

Visit this link for step by step from Sébastien : http://lists.ceph.com/pipermail/ceph-users-ceph.com/2014-August/042085.html An old ML post actually

If my cluster is quiet and on one node I want to switch the location of the journal from
the default location to a file on an SSD drive (or vice versa), what is the
quickest way to do that?  Can I make a soft link to the new location and
do it without restarting the OSDs?
