Description
It's easy if you know how: prevent the cluster from rebalancing on missing
OSD with 'noout', stop the OSD, flush his journal to the filestore, change the journal config,
initialize the new journal, restart the OSD and reset 'noout':
ceph osd set noout
<stop osd.N...perhaps service ceph stop osd.N>
ceph-osd -i N --flush-journal
<reconfigure, resize>
ceph-osd -i N --mkjournal
<restart osd.N>
ceph osd unset noout
