Hi Gregory,
i'm running kernel 3.13, which is much newer than the orig kernel of
Ubuntu 13.04:
root@bd-a:/mnt/myceph/Backup/bs3/tapes# uname -a
Linux bd-a 3.13.0-031300-generic #201401192235 SMP Mon Jan 20 03:36:48

I haven't done the math, but it's probably a result of how the df
command interprets the output of the statfs syscall. We changed the
fr_size and block_size units we report to make it work more
consistently across different systems "recently"; I don't know if that
change was before or after the kernel in 13.04.

Hi,
no, it's sure that the backup-files are so big. The output of the du-command
is correct.
The files were rsynced from an other system, which is not cephfs.

I think the result reported by df is correct. It's likely you have
lots of sparse files in cephfs.
For sparse files, cephfs increase the "used" space by the full file size.

Hi,
