Tried to create a jfs filesystem with big file option on AIX 5.2 5200-10-06-0835 today but got an strange error message.

# mklv -t jfs -y bmclv rootvg 16 hdisk0
#  crfs -v jfs -d bmclv -m /opt/bmc -A yes -a bf=ture
Filesystem Helper: 0506-526 Implementation-specific error, code =  (110)

Remove the bf option, and it works. strange.

#  crfs -v jfs -d bmclv -m /opt/bmc -A yes
# mount /opt/bmc
# df -gv /opt/bmc
