Linux认证辅导:Linux中文件大小限制
在日常的维护中,偶尔总担心某个文件会不会因为太大(超过系统限制大小),导致工作不正常。查找了一些资料,这里对文件大小限制的情况做个记录,以便以后做到心中有底
一、文件大小限制列表
二、查看数据块大小
1、直接查看操作磁盘(Block size)
[root@bas ~] <font color="#3f5fbf"># tune2fs -l /dev/sda2 </font> tune2fs 1.35 (28-Feb-2004) Filesystem volume name: /home ………… Block size: 4096 Fragment size: 4096 ………… Journal backup: inode blocks |
2、查看某个文件(IO Block)
[Oracle@bas backup]$ stat full_back.dmp File: `full_back.dmp' Size: 429687808000 Blocks: 840054384 IO Block: 4096 regular <font color="#ff1493">file</font> Device: 812h /2066d Inode: 13 Links: 1 Access: (0644 /-rw-r--r-- ) Uid: ( 501/ oracle) Gid: ( 501 /oinstall ) Access: 2011-12-18 02:00:25.000000000 +0800 Modify: 2011-12-18 20:49:31.000000000 +0800 Change: 2011-12-18 20:49:31.000000000 +0800 |
