Hi All,
tl;dr - does glance/rbd and cinder/rbd play together nicely in grizzly?
I'm currently testing a ceph/rados back end with an openstack installation.
I have the following things working OK:
1. cinder configured to create volumes in RBD
2. nova configured to boot from RBD backed cinder vol

ed when cloning a glance image into a cinder volume is
a bug? It means that the cinder client doesn't show the volume as
bootable, though I'm not sure what other detrimental effect it actually has
(clearly the volume can be booted from).
Thanks

Hi,
It seems that the combination of libvirt and ceph will happily do live
migrations.
However, when using openstack, and a nova instance is booted from a cinder
volume that itself exists in rbd, it appears from the nova code that nova
itself does not have support for instance migration due to th
Hi Maciej,
I'm using Grizzly, but the live migration doesn't appear to be changed even
in trunk. It seems to check if you are using shared storage by writing a
test file on the destination host (in /var/lib/nova/instances) and then
trying to read it on the source host, and will fail if this test

Hi Alexis,
Great to hear you fixed your problem! Would you care to describe in more
detail what the fix was, in case other people experience the same issues as
you did.
Thanks

Hi Amit,
It can, but at the moment there is some issue with keystone token caching
(in Dumpling), so every auth call hits keystone and does not cache the
token.
See here:

and here:

Hi Warren,
Try using the ceph specific fastcgi module as detailed here:
http://ceph.com/docs/next/radosgw/manual-install/
And see if that helps.
There was a similar discussion on the list previously:

Thanks

Try using passing '--debug' to the swift command. It should output the
equivalent curl command for you to use.

Hi All,
In our prior tests with 0.67.3, keystone authtoken caching was broken
causing dreadful performance - see

We upgraded to release 0.67.4 as we wanted to test the apparent fix to
authtoken caching that was included in the release notes.

Is anyone else using keystone authentication with radosgw? Anyone having
any luck getting the authtoken caching working?

Hi,
I'd have to say in general I agree with the other responders. Not really
for reasons of preferring a ML over a forum necessarily, but just because
the ML already exists. One of the biggest challenges for anyone new coming
in to an open source project such as ceph is availability of informati
Hi,
I understand from various reading and research that there are a number of
things to consider when deciding how many disks one wants to put into a
single chassis:
1. Higher density means higher failure domain (more data to re-replicate if
you lose a node)
2. More disks means more CPU/memory ho
