Hello managers!

We have a DEC Alpha 3000/900 running OSF/3.0, the machine have an
advfs filedomain containing a 10 GB fileset consisting of 5 x 2 GB
disks.

On this fileset the df command does not report the correct
Used-size. Somebody having the same problem?

bash# ls -lgi /sbin/df /usr/ucb/df /bin/df /usr/bin/df /local/gnu/bin/df
  477 -rwxr-xr-x 1 bin bin 24576 Aug 9 02:17 /bin/df
  212 -rws--x--x 1 root bin 106496 Aug 9 02:18 /sbin/df
  477 -rwxr-xr-x 1 bin bin 24576 Aug 9 02:17 /usr/bin/df
  477 -rwxr-xr-x 1 bin bin 24576 Aug 9 02:17 /usr/ucb/df
85722 -rwxr-xr-x 1 root other 24576 Jan 4 10:58 /local/gnu/bin/df

so I have 3 different df's, 2 Digital versions and one GNU version:

bash# /bin/df /work
Filesystem 512-blocks Used Avail Capacity Mounted on
work_dmn#work 20892400 21118322 0 101% /work
bash# /sbin/df /work
Filesystem 512-blocks Used Avail Capacity Mounted on
work_dmn#work 20892400 21118322 0 101% /work
bash# /local/gnu/bin/df
Filesystem 1024-blocks Used Available Capacity Mounted on
work_dmn#work 10446200 10559161 -112961 101% /work

obviously not managing this task quite well.

I can however use showfdmn to see the exact (I hope) ammount of used
space, but I would like that advanced filesystem had normal Unix
commands for reporting system information to the users.

bash# showfdmn work_dmn

      ---------- ---------- ------
        20892400 16520128 21%

Appr. 2186136 512K blocks is used. I am not surpriced when older
systems do not understand these large filesystems, but I am a bit
dissapointed about the Alpa's not managinig it.

I am wondering if df is just looking at the size of the first disk in
the file set and decides that 20892400 - 16520128 = 4372272
512K blocks, is greater than 4178480 512K blocks? Am I right here?

If not so, the limit seems to be between 4 GB and 10 GB, we have a 4
GB fileset and df report this filesystem correctly. (This fileset
consists of just one partition).

Somone reported this to Digital yet? Am I missing something?
