Hello Pratik,
I'm using virtual disks as OSDs. I prefer virtual disks over directories
because this resembles the production environment a bit better.
I'm using VirtualBox for virtualisation. The OSDs are dynamic disks, not
pre-allocated, but this shouldn't be a problem, right? I don't have the

Hi folks,
we use Ceph Dumpling as storage backend for Openstack Havana. However our
instances are not able to resize its root filesystem.
This issue just occurs for the virtual root disk. If we start instances with
an attached volume, the virtual volume disks size is correct.
Our infrastructur
Ideally you should see all your OSD hosts in the #buckets section and
those hosts should contain their respective OSDs. But you mentioned you
are using an old release of Ceph, 0.56 is it ? I am not sure if the OSD
crush map was different in that release.
Regards,
Kapil.

Hi Tijn,
I had also created my first CEPH storage cluster almost as you have
created. I had 3 VMs for OSD nodes and 1 VM for Monitor node.
All 3 OSD VMs were having one 10 GB virtual disks. so I faced almost
same problem as you are facing right now.
Then changing disk space from 10 GB to 20 GB

I think that, in general, the strategy should be to keep the stable

Hey cephers,
Just wanted to let you know there are a ton of great submissions to
the upcoming OpenStack Summit in Paris, and many of them are about
Ceph. To make it easy to find the good stuff I have aggregated the
Ceph talks for easy perusal and voting. Please head over to the
OpenStack site an

I'm trying to bring up a Ceph cluster. In our environment, access to outside
repositories is VERY restricted. This causes some BIG problems, namely, going
out to the ceph respositories. I opened up a proxy to allow this, but still
have problems:

Outstanding! I think that’s just what I need. Thanks very much for the quick

You can manually mount it and start the daemon, run ceph-disk-activate, or
just reboot the node. A reboot is the easiest.
Most setups use udev rules to mount the disks on boot, instead of writing
to /etc/fstab. If you want the details of how that works, take a look at
/lib/udev/rules.d/95-ceph-
Nope, still does it. This absolutely SUCKS! It may be a bug, but if I can’t
get this working soon, Ceph will be out the door. Where exactly is the code

OK, I’m getting farther. I changed the ceph-deploy command line to be:
ceph-deploy install --no-adjust-repos tm1cldmonl01
That keeps me from needing to grab keys.

with ceph. Unfortunately, it is only fixed in icehouse. See

I can confirm that applying the patch manually works.

This is *not* a case of that bug. That LP bug is referring to an
issue with the 'nova resize' command and *not* with an instance
resizing its own root filesystem. I can confirm that the latter case
works perfectly fine in Havana if you have things configured properly.
