Hi Bob:
mkcephfs is still usable in 0.72 with a little path.We are still
using mkcephfs on 0.72 because ceph-deploy is not good enough.
You need to patch mkcephfs.in and init-ceph.in to do this.
The patch of mkcephfs.in is you need to modify three symbols:
BINDIR=/usr/bin
LIBDIR=/us

Hi all,
Now OpenStack Nova master branch still exists a bug when you boot a VM which
root disk size is specified. The storage backend of Nova also is rbd. For
example, you boot a VM and specify 10G as root disk size. But the image is only
1G. Then VM will be spawned and the root disk size will
this one looks quite good,
Thanks you

I'm away and on my phone, I'll make it short. Overall direction is ok.
Run git submodule update because a submodule change snuck in.
I'd move the header dumping into a new RGWOp::pre_exec() callback and
fold the dump_continue() also into it.
Note that dumping bucket is on

Loic posted a script he uses for testing setups without ceph-deploy:

The utility mkcephfs seemed to work, it was very simple to use and
apparently effective.
It has been deprecated in favour of something called ceph-deploy, which
does not work for me.
I've ignored the deprecation messages until now, but in going from 70 to
72 I find that mkcephfs has finally gone.
Li,
I recommend you CC David Howells who maintains FSCache directly on your emails.

Sorry for a maybe dumm idea,
but since this seems to be the beginnig of the discussion
about integrating HSM Systems it might still be the right place for it.
Integrating an HSM is surely interesting but the prize of a commercial
System (like SAMFS) exceeds the capacity of a wide range of custo

Currently, the page allocated into fscache in readpage()
for Cifs and Ceph does not be uncached if no data read due
to io error. This patch fixes this. fscache_readpages_cancel()
is for this kind of job but taking list read * as input, so
a new routine take page * as input is introduced.

Hi Sage:

It may be even more lightweight than that depending on the Mass Storage
system intrinsic capabilities.
Here at CERN, we are testing the use of ceph in the disk cache in our
Mass Storage system and the only requirements we had was to store and

Congratulations Cephers its a great news.
