linux 划分文件系统
| will be used at the next reboot.
Syncing disks. 注意系统提示“Device or resource busy.”,当出现这一提示时,需要手工通知操作系统分区表已经作了改动 [root@hzmc bin]# partprobe /dev/sdb 3、将/dev/sdb7格式化成ext3文件系统 [root@hzmc bin]# mkfs -t ext3 /dev/sdb7 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 10010624 inodes, 20002925 blocks 1000146 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=0 611 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 23 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. You have new mail in /var/spool/mail/root [root@hzmc bin]# mkdir /siqi [root@hzmc bin]# mount /dev/sdb7 /siqi 4、将文件系统信息添加到fstab文件中,随系统自启动 /dev/sdb7 /siqi ext3 defaults 0 0 这里注意第4,5,6列数字含义 The 4th column uses the default options that are rw, suid, dev, exec, auto, nouser, and async. The 5th column in /etc/fstab is the dump option. Dump checks it and uses the number to decide if a filesystem should be backed up. If it''s zero, dump will ignore that filesystem. If you take a look at the example fstab, you''ll notice that the 5th column is zero in most cases. The 6th column is a fsck option. fsck looks at the number in the 6th column to determine in which order the filesystems should be checked. If it''s zero, fsck won''t check the filesystem. |
