For all of these use cases you're going to want to flush the journal to permanent store to make sure you don't lose any data. 1) Shut down the cosd. 2) Start it up again with the --flush-journal argument. It will run in the foreground and flush out any data in the journal. You're all set and can do whatever you want! -Greg On Thu, Jun 9, 2011 at 3:19 AM, Fyodor Ustinov <ufm@xxxxxx> wrote: > On 06/09/2011 01:09 PM, Wido den Hollander wrote: >> >> Hi, >> >> On Thu, 2011-06-09 at 01:30 +0300, Fyodor Ustinov wrote: >>> >>> Hi! >>> >>> I need to create new fresh journal for OSD server without removing data. >>> How? >> >> This can be done with: >> >> $ cosd -i<osdnum> -c /etc/ceph/ceph.conf --mkjournal > > Thanx! > >> This will reset your journal. >> >> Why do you want to do this? >> > > Many cases: > > 1.
