Hi, All!

I create garbage files.
Mounted in the main system partition for data.

#mount|grep /usr/jails/samba/
/dev/amrd0s4d.journal on /usr/jails/samba/data (ufs, asynchronous, 
local, noatime, nosuid, gjournal)
/usr/jails/basejail on /usr/jails/samba/basejail (nullfs, local, read-only)
devfs on /usr/jails/samba/dev (devfs, local)
fdescfs on /usr/jails/samba/dev/fd (fdescfs)
procfs on /usr/jails/samba/proc (procfs, local)


And now...
I see the output in the Jail "df-h" - it returns only the root mount.

# df -h
Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/amrd0s4a     18G    3.6G     13G    21%    /

If you ask specifically "df-h / data", then displays the desired data.

# df -h /data
Filesystem               Size    Used   Avail Capacity  Mounted on
/dev/amrd0s4d.journal    178G    768M    163G     0%    [restricted]

Looking sources, decided that this is due to answer "mount".
IMHO, should be able to see the file systems mounted below the directory 
of jail.
