MAX size for disk volume

[Yury Us]

Hi everybody.
I searched over ADSM.ORG and find out that there is no limitation for
volume size. But may be somebody can explain to me what am I doing
wrong?

The message I have got is :
# ./dsmfmt -g -data /vol1/vol1.dsm 120

File size for /vol1/vol1.dsm must be less than 68,589,453,312 bytes

I have on that filesystem 136Gb free space.

The computer is F50, AIX5.2 ADSMserver 5.2.0. No clients yet.

I created filesystem as follows:
  File system name                                    /vol1
  NEW mount point                                    [/vol1]
  SIZE of file system
          Unit Size                                   512bytes
+
*         Number of units                            [286261248]
#
  Mount GROUP                                        []
  Mount AUTOMATICALLY at system restart?              yes
+
  PERMISSIONS                                         read/write
+
  Mount OPTIONS                                      []
+
  Start Disk Accounting?                              no
+
  Fragment Size (bytes)                               4096
  Number of bytes per inode                           131072
  Compression algorithm                               no
  Large File Enabled                                  true
  Allocation Group Size (MBytes)                      64


Any idea would be greatly appreciated.
