Hi,
upgrading to 3.9 Kernel is the solution.
It is only needed at the client-side.

Bye,

Hi everyone,

OSDs capacity sumary is 144TB, and *when I mount CephFS on Ubuntu 14.04
then it only display **576GB*, (Currently, I'm using replicate 3 for
data pools)
(using: mount -t ceph Monitor_IP:/ /ceph -o name=admin,secret=xxxxxxxxxx")

I don't think capacity is too small?, please explain this help me!!!!!

*on Ubuntu 14.04*
Filesystem                Size  Used Avail Use% Mounted on
192.168.32.90:/    576GB  20G  556GB  1%  /tmp/ceph_mount

But when mounting on Ubuntu 12.04:
*on Ubuntu 12.04*
Filesystem                Size  Used Avail Use% Mounted on
192.168.32.90:/    144T  800G  113.6T   1%  /tmp/ceph_mount
This is most likely:

This is caused by using a more modern version of coreutils; that,
coupled with the numbers reported by Ceph for filesystem blocksizes in
older kernels, results in the above error.

To fix, either use a recent version of the fuse driver or upgrade your
kernel to a newer one that includes the commit "ceph: fix statvfs fr_size":

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=92a49fb0f79f3300e6e50ddf56238e70678e4202

(Kernels 3.9-rc1 and later should include it.)

Cheers,
David
