df -i

See if you have any free inodes left on that mounted partition.

If you need to unmount /var normally fuser -m /var will let you know whats running on it, course you fuser -k as you've mentioned too.

Running in single user mode if practical might be most beneficial. If you get desperate you can of course comment out /var in fstab and run in single user mode to the fsck the drive and/or resize2fs it.

Also bear in mind that running fsck on a filesystem with a directory containing an overwhelming number of files might end up just making your machine run out of ram, forcing you to reboot and/or corrupting the filesystem your trying to grow.

此问题为inodes(索引节点)已满,引用"inode译成中文就是索引节点，每个存储设备（例如硬盘）或存储设备的分区被格式化为文件系统后，应该有两部份，一部份是inode，另一部份是Block，Block是用来存储数据用的。而inode呢，就是用来存储这些数据的信息，这些信息包括文件大小、属主、归属的用户组、读写权限等。inode为每个文件进行信息索引，所以就有了inode的数值。操作系统根据指令，能通过inode值最快的找到相对应的文件。"

通过几台的情分析判断,每一G的空间,有120000左右的inodes

可以在格式化分区时指定inodes的大小,加个 -N参数,如

mkfs.ext3 -N 2500000 /dev/sda6 #2500000 为inodes的大小

实际应用需要要根据分区的大小来定估算

造成此问题,通常是产生了大量的小文件
