Things to add to your hard drive:
First connect the hard disk to physical, then in the shell: if we add the hard disk written to the/etc/fstab file, it is best to use the partition UUID to view the UUID command: [[email protected]~]# DUMPE2FS/DEV/SDB6 | grep UUID
DUMPE2FS 1.41.12 (17-may-2010)
Filesystem uuid:7adfac51-c8fd-4a7d-bf87-b7bf7d777d42 above illustration: UUID is a device unique identification number (can use DUMPE2FS/DEV/SDB6 | grep UUID) to get/dat A mount point is the directory to mount to, to be created in advance, if you now edit/etc/fstab under Vim you can exit Edit mode:! To perform a create command such as View Figure 0.2EXT4 is a mounted partition format this must conform to defaults is the default, we can modify the rwx 1 here to 1 for the backup partition, this option only for the partitioned directory mount point to take effect 0 for unprepared 2 scan excellent First class, there are 0 1 2 where 0 is not scanning 1 for higher priority is generally the root directory normal directory is generally set to 2 figure 0.2: When the setup is complete, use MOUNT-A to load the modified configuration we are here to see if and when the partition is in effect, you can use Df-h or Use Mount View Mount Detail table here to add the format command: [[email protected]~]# mkfs-t EXT4/DEV/SDB4 and fdisk-l See all hard disk conditions and FDISK partition the hard disk FDISK/DEV/SDB the commands inside: M view Help P view existing partition table n create e for extended partition (extended partition only You can create a primary partition number that occupies 1-4) p primary partition (only 4 of the primary partition can be created so their partition number can only be 1-4) L is a logical partition (only if the extended partition is created and the logical partition number is not specified always starts from 5) specify the partition number: (1-4 logical partition without this step) Where does the polygon begin to divide (usually a carriage return this is the beginning sector of the partition do not manually specify) in just how much space can be used (+2g or +2m+1k and other ways to specify the size of the partition) to this setting is done but note (now the partition is not saved now direct exit is not effective) W Save Q Exit After completion of the format Mkfs-t EXT4/DEV/SDB4 or MKFS.EXT4/DEV/SDB4 can then be manually mounted or added to the/etc/fstab file as described above to automatically load the boot, of course we can also mount-t ext4/d Ev/sdb4/data write to the file loaded after the Boot/etc/rc.local command: echo "mount-t ext4/dev/sdb4/data" >>/etc/rc.local The advantage is that the server boot without loading Boot speed boot Complete load failure does not affect server startup disadvantage is: Unable to implement the daily backup of the group puppet
