Linux Auto partition mount

Using Fdisk partitioning

View the mounted hard drive with the fdisk-l command, assuming that the/DEV/SDC

# fdisk-l

...

disk/dev/sdc:10.7 GB, 10737418240 bytes

Heads, Sectors/track, 10240 cylinders, total 20971520 sectors

Units = sectors of 1 * MB = bytes

Sector size (logical/physical): bytes/512 bytes

I/O size (minimum/optimal): bytes/512 bytes

Disk identifier:0x00000000

DISK/DEV/SDC doesn ' t contain a valid partition table

To partition a hard disk:

# FDISK/DEV/SDC

then, as prompted, enterN, P, 1, as welltwo-time return, and then theWqto complete the save. This way you can see the newly created partition again through Fdisk-l/DEV/SDC1

# fdisk-l

disk/dev/sdc:10.7 GB, 10737418240 bytes

Heads, Sectors/track, 10240 cylinders, total 20971520 sectors

Units = sectors of 1 * MB = bytes

Sector size (logical/physical): bytes/512 bytes

Format the second step after partitioning, for example format to EXT4 format

# mkfs-t EXT4/DEV/SDC1

The final step is to mount the hard drive:

# mkdir-p/application && mount-t ext4/dev/sdc1/application

Warning :

In order to prevent the host from a sudden power outage may pose a risk to the data, if the file system is ext3, you need to explicitly specify the "barrier=1" option at mount, such as "Mount-t Ext3-o barrier=1/dev/sdc1/mnt/ Point

2. How can I mount it automatically?

If you need to mount it automatically when the system starts, do not specify/DEV/SDC1 in the/etc/fstab directly, because the sequential encoding of devices in the cloud may change during shutdown and boot, and it is recommended to use the UUID or LABEL method to specify:

If the UUID is used, the disk's UUID is obtained first through the "BLKID/DEV/SDC1" command, for example:

/dev/sdc1:uuid= "185DC58B-3F12-4E90-952E-7ACFA3E0B6FB" type= "Ext4"

Then inside the/etc/fstab, add:

UUID=185DC58B-3F12-4E90-952E-7ACFA3E0B6FB /application ext4 Defaults 0 2

If you use label, you need to specify a label when you format the hard disk, for example:

Mkfs-t ext4-l MY_DISK_LABEL/DEV/SDC1

Then inside the/etc/fstab, add:

Label=my_disk_label/mnt/mydisk EXT4 Defaults 0 2
