Storage partition mount

Storage description:

Huawei storage enclosure 36T, after the completion of raid 2.0, the actual use of about 20T, Huawei manufacturers are required to be divided into three disks: one 10T and two 5T.

When the storage disk of the manufacturer is finished, you need to restart the server reboot before you can see the drive letter in the fdisk-l command.

There are two commands for partitioning:

1. Fdisk: it can only be stored below 2T. More than 2T can mount the entire disk, but it cannot be partitioned.

2. Parted: it can be divided into more than 2T storage. It can be used more widely.

1.fdisk command: 1.1 fdisk partition

Fdisk / dev/sdb

1.2 formatted disk

Mkfs.ext3 / dev/sdb

Create the directory mkdir / oradata

1.3 Mount

Method 1: first mount and then add restart self-startup

Mount / dev/sdb / oradata

Vi / etc/fstab

Finally, add / dev/sdb / oradata default 0 0

Method 2: add restart self-boot before mounting

Vi / etc/fstab

Finally, add / dev/sdb / oradata default 0 0

Mount-a

1.4 View after the mount is completed

2.parted command: 2.1View all disk status

[root@jetsen ~] # parted-l

2.2 use the parted tool to create partitions greater than 2T

[root@jetsen ~] # parted / dev/sde

2.5 create a file system through the parted tool

[root@jetsen ~] # parted / dev/sdd-Select the disk to format

GNU Parted 1.8.1

Using / dev/sdd

Welcome to GNUParted! Type 'help' to view a list of commands.

(parted) mkfs 2ext3-formatted type is ext3 partition number is 2-

Warning: Theexisting file system will be destroyed and all data on the partition will

Be lost. Do youwant to continue?

Parted: invalidtoken: 2

Yes/No? Yes-reconfirm whether it is formatted

Partition number?2-enter the disk partition number again

File system? [ext2]?-the type of format

(parted)

2.6 check whether the formatting is successful:

(parted) p-check if the file system is formatted

Model: VMware,VMware Virtual S (scsi)

Disk / dev/sdd:1100GB

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

Partition Table:gpt

Number Start End Size File system Name Flags

1 17.4kB 10.0GB 10000MB part1

2 10.0GB 100GB 90.0GB ext2 part2-you can see that the file system type is ext2, but you can confirm that the file system has been formatted.

The mount method is the same as the fdisk command.
