Linux add hard drives and mounts

1. Use Fdisk-l to view hard drive details

Analysis:

2. Partition initialization

Fdisk/dev/sdb

Analysis: Parsing of individual parameters

1. Enter m to display all the commands listed below.

　　　　　　　　2. Enter p to display the hard disk segmentation and print the partition table.

3. Enter a to set the boot area of the hard drive.

　　　　　　　　4. Enter N to set a new hard disk partition .

4.1. Enter the E-drive as the [extended] partition (extend).

4.2. Enter the P drive as [primary] partition (primary).

5. Enter T to change the drive partition properties.

T: Partition system ID number L:82:linux swap83:linux86:ntfs window partition

6. Enter d to delete the hard drive partition properties.

　　　　　　7. Enter Q End does not deposit the hard disk partition attribute.

　　　　　　　　8. Enter W to end and write to disk partition properties

Note: 1.

Partition number (1-4): 2 #如果这里已经创建了1个分区, then this value cannot be entered 1.

3. Partitioned file Systems

Assigning file systems to partitions: Ext2 and Ext3

MKE2FS/DEV/SDB1 #默认是ext2, this command is to create a file system

mke2fs -j/dev/sdb1 #-j is ext3

Mke2fs-t EXT4/DEV/SDB1 #ext4创建文件系统

e2fsck -P/DEV/SDB1 #检查文件系统: File, Sector has error parameter-P is automatic repair

This filesystem would be automatically checked every mounts orthe days of the whichever comes first.   use tune2fs-c or-i to override.
Parse: Mount 37 or 180 days after file system detection

TUNE2FS-L/DEV/SDB1 #查看文件系统的详细信息-L View Details-C 30/DEV/SDB1 set how many times to check (Mount how many times to detect)-I 70d/dev/sdb1 70-day check (how many days detection)

E2LABEL/DEV/SDB1 Www-data #指定转标

Findfs Www-data #查找转标

4. Mounting

Vim/etc/fstab The permanent mount configuration is added as follows in the file:/dev/sdb1/opt ext3 defaults 1 1mount: View partition Format-A mount information immediately effective-t ext3 /dev/sdb1/opt temporary mount Linux partition-T VFAT/DEV/SDC1//media/usb U-Disk Mount window partition-O-loop docs.iso/media/iso mount image file Mount M Edia/cdrom Optical drive Mount umount/opt unload mount
