Hello,
The way Wido explained is the correct way. I won't deny, however, last
year we had problems with our SSD disks and they did not perform well.
So we decided to replace all disks. As the replacement done by Ceph
caused highload/downtime on the clients (which was the reason we wanted
to repl
The fact that you are all SSD I would do exactly what Wido said -
gracefully remove the OSD and gracefully bring up the OSD on the new
SSD.
Let Ceph do what its designed to do. The rsync idea looks great on
paper - not sure what issues you will run into in practise.

Hi guys,
I'm running a ceph cluster using 0.94.9-1trusty release on XFS for RBD
only. I'd like to replace some SSDs because they are close to their TBW.
I know I can simply shutdown the OSD, replace the SSD, restart the OSD and
