AIX中缺less磁盘空间

我有一个AIX服务器..分区应该有39GB的空间..但是当我做一个DF – K，它表明，我已经用完了几乎24GB的空间…但是，当我列出的一切下，挂载点..文件的大小不值得太多的空间..所以空间失踪到什么地方？

$ $ df -k Filesystem 1024-blocks Free %Used Iused %Iused Mounted on /dev/hd4 131072 4720 97% 1724 59% / /dev/hd2 1703936 541252 69% 34662 22% /usr /dev/hd9var 131072 76636 42% 484 3% /var /dev/hd3 1048576 1045528 1% 94 1% /tmp /dev/hd1 2097152 1361216 36% 16565 6% /home /proc - - - - - /proc /dev/hd10opt 131072 46644 65% 1530 13% /opt /dev/lvlos 3145728 2677572 15% 8528 2% /los /dev/lvu01 16908288 10989512 36% 19273 1% /u01 /dev/lvu02 40894464 14807568 64% 12 1% /u02 $ pwd / $ cd /u02 $ pwd /u02 $ ls -lRa total 24 drwxrwxrwx 5 root system 256 Oct 03 13:45 . drwxr-xr-x 21 root system 4096 Nov 11 14:55 .. drwxrwxrwx 2 root system 256 Oct 04 15:31 db_dump drwxr-xr-x 2 root system 256 Sep 24 2009 lost+found drwxrwxr-x 2 oracle oinstall 8192 Nov 16 07:07 oradata ./db_dump: total 0 drwxrwxrwx 2 root system 256 Oct 04 15:31 . drwxrwxrwx 5 root system 256 Oct 03 13:45 .. ./lost+found: total 0 drwxr-xr-x 2 root system 256 Sep 24 2009 . drwxrwxrwx 5 root system 256 Oct 03 13:45 .. ./oradata: total 1169688 drwxrwxr-x 2 oracle oinstall 8192 Nov 16 07:07 . drwxrwxrwx 5 root system 256 Oct 03 13:45 .. -rw-r----- 1 root system 1994 Mar 01 2010 PJ_UAT_bkcrontab_without_gzip -rw-r----- 1 root system 2060 Mar 01 2010 PJ_UAT_crontab_with_gzip -rwxrwxrwx 1 root system 598843639 Nov 14 20:49 abmb_glos_uatlosdb_20110105_0200.dmp.gz -rw-r----- 1 root system 269 Mar 01 2010 alc_sizing.sh -rw-r----- 1 oracle oinstall 245 Nov 23 2009 import.parfile -rwxrwxrwx 1 root system 48 Mar 01 2010 pj_uat_gzip_dump_files.sh $
