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.)
