Linux add hard disk with Fdisk partition, MKE2FS formatted partition, auto mount

The Fdisk tool can only partition disks below 2T, using parted partitions above 2T

First, use FDISK to partition the specified hard disk

[Email protected] ~]# Fdisk/dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF Disklabel
Building a new DOS disklabel with disk identifier 0x21248295.
Changes'll remain in memory only, until the decide to write them.
After that, of course, the previous content won ' t is recoverable.

Warning:invalid flag 0x0000 of partition Table 4 would be a corrected by W (rite)

Warning:dos-compatible mode is deprecated. It ' s strongly recommended to
Switch off the mode (command ' C ') and change display units to
Sectors (Command ' u ').

Second, format the partition

1, using MKFS.EXT4 format/DEV/SDB5 (method one)

[Email protected] ~]# MKFS.EXT4/DEV/SDB5
MKE2FS 1.41.12 (17-may-2010)
Filesystem label=
OS Type:linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
51744 inodes, 206829 blocks
10341 blocks (5.00%) reserved for the Super user

7 Block groups
32768 blocks per group, 32768 fragments per group
7392 inodes per group
Superblock backups stored on blocks:

Writing Inode Tables:done
Creating Journal (4096 blocks): Done
Writing superblocks and filesystem accounting Information:done

This filesystem would be automatically checked every mounts or
Whichever comes first. Use Tune2fs-c or-i to override.

2. Format the partition using Mke2fs (method two)

[Email protected] ~]# mke2fs-t ext4-b 2048-m 1-l ming/dev/sdb1

-B Specify block (block) size

-m specifies reserved n% space

-L Label

[Email protected] ~]# mke2fs-t ext4-b 2048-m 1-l ming/dev/sdb1
MKE2FS 1.41.12 (17-may-2010)

16384 blocks per group, 16384 fragments per group

Superblock backups stored on blocks:
16384, 49152, 81920, 114688, 147456, 409600, 442368

Writing Inode Tables:done

This filesystem'll be automatically checked every Notoginseng mounts or
Whichever comes first. Use Tune2fs-c or-i to override.

Third, Mount

1. Manual Mounting

[Email protected] ~]# mount/dev/sdb5/mnt/
[Email protected] ~]# DF-HT
Filesystem Type Size used Avail use% mounted on
/dev/sda3 ext4 8.7G 926M 7.4G 11%/
Tmpfs tmpfs 491M 0 491M 0%/dev/shm
/DEV/SDA1 ext4 194M 27M 158M 15%/boot
/DEV/SDB5 ext4 796M 17M 739M 3%/mnt

[[email protected] ~]# mount-o noatime,rw/dev/sdb1/home/ming/disk1//noatime do not change read time

2, automatic mount, modify the/etc/fstab file

[Email protected] ~]# Blkid
/dev/sda1:uuid= "AD1CFBB0-1621-4B2C-B10A-F2EDE0D863BC" type= "Ext4"
/dev/sda2:uuid= "2b68ad5b-f328-4cd1-8d3d-a21b19574321" type= "swap"
/dev/sda3:uuid= "7A56F94A-8C3F-4B2F-8CF3-A68E901D5CAA" type= "Ext4"
/dev/sdb1:label= "Ming" uuid= "48cc8e42-98c3-46d0-9895-b04e073b39bd" type= "Ext4"
/dev/sdb5:uuid= "42348B39-109F-49C6-B34C-C5D2CCFAD5A2" type= "Ext4"

[Email protected] ~]# Vim/etc/fstab
/dev/sdb5/mnt ext4 Defaults 0 0 (whether backup, whether detected, 0 means no)

Defaults=rw,suid,dev,exec,auto,nouser,async/sync

3, boot automatically loaded configuration file/etc/rc.local, storage need to boot automatic loading command
[Email protected] ~]# ls/etc/rc.local
/etc/rc.local

[Email protected] ~]# vim/etc/rc.local

Mount/dev/sdb1/home/ming/disk1

[email protected] ~]# mount
/dev/sda3 on/type ext4 (rw)
Proc On/proc type proc (rw)
Sysfs On/sys type SYSFS (rw)
Devpts on/dev/pts type devpts (rw,gid=5,mode=620)
