Hi Neil,
I've added RBD backups secondary clusters within Openstack to the list of

I moved the content of the session to an etherpad for collaborative editing
Ok thanks guys. Hope we will find something :-).

Any word on what the status of this is? I just ran into it myself,

Looking at the bug in tracker, it's resolved. Is this going to be

If an invalid layout is provided to ceph_osdc_new_request(), its
call to calc_layout() might return an error. At that point in the
function we've already allocated an osd request structure, so we
need to free it (drop a reference) in the event such an error
occurs.
The only other value
The bio_seg field is used by the ceph messenger in iterating through
a bio. It should never have a negative value, so make it an
unsigned.
Change variables used to hold bio_seg values to all be unsigned as
well. Change two variable names in init_bio_iter() to match the
convention used
This series refactors the code involved with identifying the
details of the name, offset, and length of an object involved
with an osd request based on a file layout. It makes the focus
of calc_layout() be filling in an osd op structure based on the
file layout it is provided. The caller
Have calc_layout() pass the computed object number back to its
caller. (This is a small step to simplify review.)

Move the formatting of the object name (oid) to use for an object
request into the caller of calc_layout(). This makes the vino
parameter no longer necessary, so get rid of it.

The only remaining reason to pass the osd request to calc_layout()
is to fill in its r_num_pages and r_page_alignment fields. Once it
fills those in, it doesn't do anything more with them.
We can therefore move those assignments into the caller, and get rid
of the req parameter entirely.
Note,
This series makes the fields related to the data portion of
a ceph message not get manipulated by code outside the ceph
messenger. It implements some interface functions that can
be used to assign data-related fields. Doing this will allow
the way message data is managed to be changed
Use distinct fields for tracking the number of pages in a message's
page array and in a message's page list. Currently only one or the
other is used at a time, but that will be changing soon.

The page alignment field for a request is currently set in
ceph_osdc_build_request(). It's not needed at that point
nor do either of its callers need that value assigned at
any point before they call ceph_osdc_start_request().
So move that assignment into ceph_osdc_start_request().
Define a function ceph_msg_data_set_pages(), which more clearly
abstracts the assignment page-related fields for data in a ceph
message structure. These fields should never be set more than once
(add BUG_ON() calls to guarantee that). Use this new function in
the osd client and mds client.
Define ceph_msg_data_set_pagelist(), ceph_msg_data_set_bio(), and
