Dear all,
I am trying to mount cephfs to 2 different mount points (each should have their
respective pools and keys). While the first mount works (after using set_layout
to get it to the right pool), the second attempt failed with "mount error 12 =
Cannot allocate memory". Did I miss some steps

We solved this problem at ParaScale by enabling users to enter any fancy

Hi,
So the first error below is that /var/run/ceph isn't created when
installing the ceph RPM(s). This is becasuse of line 440 in

Thanks Greg,
The concern I have is an "all eggs in one basket" approach to storage design.
Is it feasible, however unlikely, that a single Ceph cluster could be brought
down (obviously yes)? And what if you wanted to operate different storage
networks?

I would like to make a local mirror or your yum repositories. Do you support

Giuseppe,
My apologies for the misunderstanding. I do have some information on
the librados API. There is a Python binding for the Ceph Filesystem
in the repository. For information on cloning the Ceph repository, see

Hi Derek,
Are you sure the package is installed on the target? (Did you ceph-deploy
install ) It is probably caused by /var/lib/ceph/mon not

Derek-
Please also try the latest ceph-deploy and cuttlefish branches, which
fixed several issues with el6 distros. 'git pull' for hte latest
ceph-deploy (clone from github and ./bootstrap if you were using the
package) and install with
./ceph-deploy install --dev=cuttlefish cbcbobj00.umiacs
I built the 3.10-rc rbd module for a 3.8 kernel yesterday, and only
had one thing to add (I know I'm reviving an old thread).
There is one folder missing from the original list of files to use:
include/linux/crush/*
That would bring everything to:
include/keys/ceph-type.h

Thanks! Craig.
umount works.
About the time skew, I saw the log said the time difference should be less than
50ms. I setup one of my nodes as the time server, and the others sync the time
with it. I don't know why the system time still changes frequently especially
after reboot. Maybe it's bec

Hi List,My ceph cluster has two osds on each node. One has 15g capacity, and

It's interesting that, after I took the 15g osd out of the cluster, the cluster

Yes. I have read the article you mentioned. But I also read another one:

Hi Alex,
What versions of Qemu are recommended for this?
I would go with version 1.4.2 (I don't know what the official
recommendation is).
which is the implementation of using asynchronous flushing
in Qemu. That's only in 1.4.3 and 1.5 if I use the upstream
As far as I know, it is in 1.4
I'm planning on running Ceph Cuttlefish with Qemu/KVM using Qemu's
inbuilt RBD support (not kernel RBD). I may go beyond Cuttlefish.

ships with Ubuntu Precise LTS which the base OS in use, so this
