磁盘空间已满

磁盘空间已满

设置 Ubuntu 10.04 服务器时，/ 磁盘空间在 df 下显示已满，但 du 未显示任何已使用的空间。这有多个 Gluster FS 挂载。

我尝试过强制 FSCK，但无济于事。

~# df -h

我尝试过 tune2fs，但出现了同样的问题

最后一个问题：df 显示已 100% 使用，但没有其他已知的修复方法？

答案1

我也遇到过这个问题。这里为您提供解决方案，请卸载 /mnt/sanvol09 并检查原始文件夹。在安装之前，您可能在该文件夹中有文件。安装后，您将无法看到它们。因此，请继续卸载，清理该文件夹，就这样。

答案2

您可以使用以下工具检查打开的文件（任何进程仍在使用但被删除的文件）

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

在 lsof 输出中，你可以看到已删除文件的关键字 removed。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
