Thanks Josh! This is a lot clearer now.
I understand that librbd is low-level, but still, a warning wouldn't
hurt, would it? Just check if the size parameter is larger than the
cluster capacity, no?
Thank you for pointing out the trick of simply deleting the rbd_header,
I will try that now.
hello,
is there some methods to monitor osd nodes? for example the free size of
one osd node.

Yes, I understand that creating an image larger than the cluster may
sometimes be considered a feature. I am not suggesting it should be
forbidden, simply that it should display a warning message to the operator.

the weird thing is that I have some volumes that were created from a snapshot,
that actually boot (they complain about not being able to connect to the
metadataserver (which I guess is a totally different problem) but in the end,
they come up.

I'm playing with the boot from volume options in Havana and have run into
problems:

The following things do work:
- glance images are in rbd
- cinder volumes are in rbd

Is this statement accurate?
As I understand DRBD, you can replicate online block devices reliably,
but with Ceph the replication for RBD images requires that the file
system be offline.
Thanks for the clarification,

Thanks, Alfredo.
The challenge is that it is calling those links when issuing the following

As an OSD is just a partition, you could use any of the monitoring packages out
there? (I like opsview…)
We use the check-ceph-status nagios plugin[1] to monitor overall cluster

Thanks, reread that section in docs and found tunables profile - nice

need RSS to follow all changes :) )
Still problem persists in a different way.

Sorry, I was mixing concepts.
I was thinking of RBD snapshots, which require the file system to be
consistent before creating.
I have been exploring an idea for creating remote, asynchronous copies
of RBD images, hopefully with some form of delayed state updating. I've
been reviewing the feature

What do you mean the filesystem disappears? Is it possible you're just
pushing more traffic to the disks than they can handle, and not waiting
long enough for them to catch up?
