df and showfdmn discrepancy

Hi managers,

SYS: DS10 wth external SCSI pedastal and 6 x 36GB disks. Tru64 5.1.
        advfs fileystsem throughtout.

I did a df today and noticed that one domain was at 100% capacity. I
was a bit shocked because this domain was just over half full (about
14GB free) at the end of last week.

I did a find with mtime -7 and there are only a dozen files added in
the last seven days. So I did a showfdmn on the domain and it shows:

     Id Date Created LogPgs Version Domain Name
3b04fd12.000b9595 Fri May 18 11:44:34 2001 512 4 usr_0

  Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
   1L 71132000 34372560 52% on 256 256
/devices/disk/dsk1c

I figure that the showdfm is correct but I am baffled by the sudden
discrepancy. I can't see anything that exactly replicates my problem
in the archives but I saw something about quotacheck -v. I did this
and got:
root fixed: blocks 121 -> 41
system fixed: blocks 5671969 -> 5671889

Still df (and vdf) is reporting the wrong usage:

Filesystem 1024-blocks Used Available Capacity Mounted on
spl_0#usr0 9209200 9209200 0 100% /usr0

          Id Date Created LogPgs Version Domain Name
3b04fd12.000b9595 Fri May 18 11:44:34 2001 512 4 usr_0

  Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
   1L 71132000 34365504 52% on 256 256
/devices/disk/dsk1c

I wonder if df is looking at a completely different disk as I have a
internal 9GB disk? I also ran verify with the -a and then with -f but
still no change.

Has anyone seen this before? I am almost certain that I have about
14Gb left as files are being added and there is no trouble there.

Thanx.
Dp.
