Do you have Virtual Hot Spare space enabled? It also hides as dark matter from df.

Im guessing it has something to do with the protection scheme you've choosen and the stripe size... And how isilon deals with files smaller than its stripe size...

Some size is used by system partition rest you can compare output from both commands

isetta-2# df -h /ifs

Filesystem    Size    Used   Avail Capacity  Mounted on

OneFS         5.0T    691G    4.3T    14%    /ifs

isetta-2# df -h

Filesystem               Size    Used   Avail Capacity  Mounted on

/dev/mirror/root0        989M    483M    427M    53%    /

devfs                    1.0K    1.0K      0B   100%    /dev

/dev/mirror/var0         989M    110M    800M    12%    /var

/dev/mirror/var-crash    1.9G    327M    1.5G    18%    /var/crash

/dev/md0                  62M    470K     56M     1%    /tmp/ufp
