磁盘空间满

Question

设置Ubuntu10.04服务器时，/ disk空间在df下显示完全，但是du没有显示任何所使用的空间。这有几个安装到Gluster FS‘。

我试过强迫FSCK，但没有结果。

~# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/md0              141G  132G     0 100% /
none                  3.0G  224K  3.0G   1% /dev
none                  3.0G     0  3.0G   0% /dev/shm

none                  3.0G     0  3.0G   0% /lib/init/rw

我尝试了一个tune2fs，也出现了同样的问题

# du -h --max-depth=1 --one-file-system /
4.0K    /selinux
0   /proc
47M /boot
31M /mnt

最后一个问题: df秀100%使用，而不是其他已知的修补程序？

Answer 1

我也有这个问题。这里为您解决方案，请umount /mnt/sanvol09并检查原始文件夹。也许在挂载之前你在那个文件夹里有文件。挂上之后，你就看不到它们了。所以，继续，清理那个文件夹，就这样。

Answer 2

可以使用以下工具检查打开的文件(任何进程仍在使用时删除的文件)

lsof | sort -nrk 7,7 | head -20、df -h /和du -x -sh /

在lsof输出中，可以看到已删除文件的关键字已删除。例如

root@demobox:/root : lsof | grep -i deleted
dsmcad    25449       root  txt       REG              253,0  4843037     459377 /opt/tivoli/tsm/client/ba/bin/dsmcad (deleted)
root@demobox:/root : ls -l /opt/tivoli/tsm/client/ba/bin/dsmcad
ls: cannot access /opt/tivoli/tsm/client/ba/bin/dsmcad: No such file or directory
