 inode这个词大多资料都是译为索引节点，在ext3文档系统，调整磁盘的inode number。这里只是调整inode number这个参数，假如想调整inode size或是blocksize等能够具体mkfs.ext3命令。 系统内核版本：2.4.21-32 1。卸载文档系统 #>umount /data0 2。建立文档系统，指定inode节点数 #>mkfs.ext3 /dev/sda6 -N ”inode节点数“ 3。修改fstab文档 #>vi /etc/fstab /dev/sda6 /data0 ext3 defaults 1 2 4，挂载文档系统 #>mount -a 4。查看修改后的inode参数 #>dumpe2fs -h /dev/sda6 | grep node [注意]调整inode数会格式化磁盘，执行前应确定磁盘上没有重要数据或是先备份数据 mkfs.ext3的和inode相关的参数介绍 -i bytes-per-inode Specify the bytes/inode ratio. mke2fs creates an inode for every bytes-per-inode bytes of space on the disk. The larger the bytes-per-inode ratio, the fewer inodes will be created. This value generally shouldn?? be smaller than the blocksize of the filesystem, since then too many inodes will be made. Be warned that is not possible to expand the number of inodes on a filesystem after it is created, so be careful deciding the cor- rect value for this parameter. -N number-of-inodes overrides the default calculation of the number of inodes that should be reserved for the filesystem (which is based on the number of blocks and the bytes-per-inode ratio). This allows the user to specify the number of desired inodes directly. |
