根文件系统 (ext4) 上的孤立 inode；顽固的问题

Question

在我可信赖的系统（vmWare 下的虚拟机、台式机和笔记本电脑）上，我们遇到了以下问题。

根文件系统似乎具有从未标记为“空闲”的 inode。在服务器运行一个月后，df -i显示 / (an ext4 fs)上的 inode 使用率为 100% 。

进行预览fsck显示错误。我们执行touch/ forcefsck，然后重新启动系统。这正确的孤立inode，但问题再次出现。

上没有消息/var/log/syslog。这些系统通过 Trusty 上的最新更新和内核可用是最新的。

# fsck -nf /
fsck from util-linux 2.20.1
