I was looking at replacing an osd drive in place as per the procedure here:
http://www.spinics.net/lists/ceph-users/msg05959.html
"If you are going to replace the drive immediately, set the “noout”
flag. Take the OSD “down” and replace drive. Assuming it is
mounted in the same place as the bad drive, bring the OSD back up.
This will replicate exactly the same PGs the bad drive held back
to the replacement drive."
But the new drive mount will be blank - what happens with the journal,
keyring etc? does starting the OSD process recreate them automatically?
thanks,
