Linux disk partition combat case (must see article) _linux

I. View a newly added disk

[root@localhost/]# fdisk-l
 
disk/dev/sda:53.7 GB, 53687091200 bytes, 104.8576 million sectors
Units = Sector of 1 * the bytes
    sector size (logical/Physical): 512 Bytes/512 bytes
I/o size (min/best): 512 Bytes/512 bytes
disk label type: dos
disk identifier: 0X0009F1D1
 
  device Boot   Start     End   Blocks  Id System
/dev/sda1  *    2048   1026047   512000  Linux
/dev/sda2     1026048   5253119   2113536  Linux swap/solaris
/dev/sda3     5253120  104857599  49802240  Linux
 
disk/dev/sdb:21.5 GB, 21474836480 bytes, 41,943,040 sectors
Units = Sector of 1 * 5 Bytes
sector size (logical/Physical): 512 Bytes/512 bytes
I/o size (min/best): 512 Bytes/512 bytes
disk label type: dos
disk identifier: 0x12f9141b
    device Boot   Start     end   Blocks  Id System
/dev/sdb1      2048  10487807   5242880  Linux

two. Disk partitioning

[Root@localhost/]# Fdisk/dev/sdb welcome the use of Fdisk (Util-linux 2.23.2).
The changes will remain in memory until you decide to write the changes to disk.
 
 
Please think twice before using the Write command. Command (input m get help): N (n to create partition) Partition Type:p Primary (1 primary,                                                                   0 extended, 3 free) (p primary partition) E extended (e is extended partition) Select (default p): P Partition code (2-4, default 2): 2 Start Sector (10487808-41943039, default 10487808): will use default Value 10487808 last sector, + sector or +size{k,m,g} (10487808-41943039, default is 41943039): +5g (size of partition) partition 2 is set to Linux type, size to 5 GiB command (input m get help): W (w Save settings) the partition table has been altered
 
!
 
Calling IOCTL () to re-read partition table.
Warning:re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table is used at the next reboot or after you run Partprobe (8) or KPARTX (8) is synchronizing the disk.

Three. Disk format

[Root@localhost/]# partprobe/dev/sdb2                          (Refresh partition table)
[root@localhost/]# mke2fs/dev/sdb2 mke2fs 1.42.9
(28- Dec-2013)
file System label =
OS type:linux
block size =4096 (log=2) chunking
size =4096 (log=2)
stride=0 blocks, stripe Width=0 blocks 327680 inodes 1310720 blocks-65536 blocks
(5.00%) reserved for the super User
first block of data =0
   maximum filesystem blocks=1342177280 block
groups 32768 blocks/
group, 32768 fragments per group
8 Inodes per group
superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736
   allocating Group tables: Completing the              
inode table being written: completing              

Four. Create a directory and mount the partition

[Root@localhost/]# mkdir/soft
[root@localhost/]# Mount/dev/sdb2/soft

Five. Set the boot self mount

[Root@localhost/]# vim/etc/fstab 
/dev/sdb2     /soft     xfs     defaults    0   0

Six. View Mount

[root@localhost/]# df-ht
file system    type   capacity used available% mount point
/dev/sda3   xfs    48G 3.7G  44G  8%/
devtmpfs    devtmpfs 906M   0 906M  0%/dev
tmpfs     tmpfs   914M  80K 914M  1%/dev/shm
tmpfs     tmpfs   914M 8.9M 905M  1%/run
tmpfs     tmpfs   914M   0 914M  0%/sys/fs/cgroup
/dev/sda1   xfs    497M 116M 382M  24%/boot   /dev/sdb1 ext2   5.0G  11M 4.7G  1%/dvd
/dev/sdb2   ext2   5.0G  10M 4.7G  1%/soft

The above is a small series for everyone to bring the Linux disk partition combat case (must see article) all content, I hope that we support cloud Habitat Community ~
