我AIX6.1下的一个文件系统，一个很大的文件被我删除后，该文件系统利用率并未下降，即使umount了再mount起来也不行
甚至操作系统都重启了，也不行，于是尝试fsck修复文件系统，然后再mount起来就可以了！
[root@testdb1:/]# fsck -y /dev/fslv01
The current volume is: /dev/fslv01
Primary superblock is valid.
*** Phase 1 - Initial inode scan
*** Phase 2 - Process remaining directories
*** Phase 3 - Process remaining files
*** Phase 4 - Check and repair inode allocation map
File system inode map is corrupt (FIXED)
Superblock marked dirty because repairs are about to be written.
*** Phase 5 - Check and repair block allocation map
Block allocation map is corrupt (FIXED)
File system is clean.
Superblock is marked dirty (FIXED)
All observed inconsistencies have been repaired.

另外，之前rman中删除归档日志，然后所在文件系统利用率里面，文件系统利用率为 -1%
同样使用fsck -y /dev/lvname 的命令进行修复即可。
