"/" c0t0d0s0 showing 100%.

hi
I recently started looking after server with sunsolaris os. it is dual host system. In one server the '/' showing 56% in other it is showing 100% in df -k.
the status of slice was
used avail capacity mounted on
/dev/dsk.c0t0d0s0 961181 95**** 0 100%
After reoving some files the avail is now 922028 but capacity is still 0 and it still showing 100% whereas actual it supposed to be 95%. The du -s showing almost same in both the server. please help me.

Pls capture and post various outputs. It be much clearer

The details on df -k are

file system                used avail  capacity mounted on
/dev/dsk/c0t0d0s0 961181 922028           0  100%   /
/dev/dsk/c0t0d0s6 9611181 799169   104342 89%  /usr
/dev/dsk/c0t0d0s3 9611181 33254     870257 4%    /var
/dev/dsk/c0t0d0s7 3776238 3297802  440674  89% /export/home
/dev/dsk/c0t0d0s5 961181 674966     228545  75% /opt
swap                    1038440 288        1038152   1% /tmp

in other server the similar disk partion available . but the / use is 55%. i have gone through the files but find almost similar size.
further even after deleting some files in / dir there is no change of %. still it is 100% though the used value has been reduced.
pl help.

Is it possible that file handles to the deleted files are still open?

Are you running any application on the server?
Most of the times these applications produce log files
which are being logged on to / . You may need to identify
these logs if any and delete them.
