根文件系统 (ext4) 上的孤立 inode；持续存在的问题

Question

在我的可信系统（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。

根文件系统似乎有从未被标记为“空闲”的 inode。服务器运行一个月后， /（一个）df -i上的 inode 使用率显示为 100% 。ext4 fs

预览fsck显示有错误。我们执行touch/ forcefsck，然后重新启动系统。这纠正了孤立的 inode，但问题再次出现。

上没有消息/var/log/syslog。系统已更新至 Trusty 上的最新更新和内核。

# fsck -nf /
fsck from util-linux 2.20.1
