How? - stop a ceph-osd daemon, then - ceph-osd --flush-journal -i NNN - set/adjust the journal symlink at /var/lib/ceph/osd/ceph-NNN/journal to point wherever you want - ceph-osd --mkjournal -i NNN - start ceph-osd This won't set up the udev magic on the journal device, but that doesn't really matter if you're not hotplugging devices. sage _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
