I haven't done the initial setup in several years, but as I recall,
once Ceph was built it was a simple matter of doing New Makefile
Project with Existing Code in Eclipse. Make sure you've got the C++
version of Eclipse.
Other than that, I'm afraid you'll need to go through the Eclipse
support

Loic,
Sorry for the delay in getting back to you about these patches. :( I

I do have some comments, though.

Just an update: this data stayed after pool deletion, so there is
probably a way to delete garbage bytes on live pool without doing any
harm(hope so), since it is can be dissected from actual pool pool data
placement, in theory.
I actually still do this. Set it up Ceph outside of Eclipse initially, then
import it as a project with an existing Makefile. It should pick up on
everything it needs to well enough. :)

Well, that sure is a lot of rbd objects. Looks
Try ceph osd set noout beforehand and then ceph osd unset noout. That will
prevent any OSDs from getting removed from the mapping, so no data will be
rebalanced. I don't think there's a way to prevent OSDs from getting zapped on
an individual basis, though.
This is described briefly in the
I believe this is because you specified hostname rather than host for the
OSDs in your ceph.conf. hostname isn't a config option that anything in Ceph
recognizes. :)

Apart from the things that Wido has mentioned, you say you've set up 4 nodes
