Guide to hard disk formatting, partitioning and mounting

The newly added blank hard disk (assuming it can be identified, if you can't identify the need for online array, you can install MegaCli to do the array), you need to partition, format, and mount.

1. How to make an array online

1. Install MegaCli

Http://www.lsi.com/support/Pages/Download-Results.aspx?keyword=MegaCli

Select the appropriate version of the installation package

Decompress after download

Unzip CSA1.5-MegaCli_REL80571.zip

Cd MegaCLI/MegaCli_Linux

Rpm-ivh MegaCli-8.05.71-1.noarch.rpm

Installation completed

Ln-s / opt/MegaRAID/MegaCli/MegaCli64 / usr/bin/

Install it under / opt by default and establish a soft link to / usr/bin

2. MegaCli-PDList-aAll [displays all physical information] to find the newly added drive letter

Raid0:

/ opt/MegaRAID/MegaCli/MegaCli64-CfgLdAdd-R0 [32:2] WB ADRA Direct NoCachedBadBBU-a0

Raid1:

/ opt/MegaRAID/MegaCli/MegaCli64-CfgLdAdd-R1 [32 WB ADRA Direct NoCachedBadBBU 2 and 3] WB ADRA Direct NoCachedBadBBU-a0

Description

R0: it means to do raid 0

R1: it means raid1.

[32:2] New hard drive number

32 means Enclosure Device ID:32.

2 refers to the SLOT Number:2 slot

(view all physical hard disk status / opt/MegaRAID/MegaCli/MegaCli64-PDList-a0)

-a0-0 is the array card number Adapter # 0

Wb ADRA direct Nocachedbadbbu refers to the following parameters

[WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU]

2. In this way, you can recognize the disk

The following drive letters (sdb) are examples. The drive letters of the new hard disk are determined by viewing parted-l.

A small hard drive (less than 2T)

Zoning

Fdisk / dev/sdb

Formatting

Mkfs.ext4 / dev/sdb1

Mounting

Mount / dev/sdb1 / data1

Uid=blkid / dev/sdb1 | awk'{print $2}'| awk-F'"'{print $2}'`

Echo "UUID=$uid / data1 ext4 defaults 0" > > / etc/fstab

Two large hard drives (greater than or equal to 2T)

Use parted to mount a hard disk exceeding 2T by modifying the partition format to GPT, and quickly format it with xfs. If you exceed 6T, you must use xfs format)

Zoning

Parted-s / dev/sdb mklabel gpt

Parted-s / dev/sdb mkpart primary "0-1"

Formatting

Yum install kmod-xfs xfsprogs-y

Modprobe xfs

Mkfs.xfs / dev/sdb1

Mounting

Mount / dev/sdb1 / data1

Uid=blkid / dev/sdb1 | awk'{print $2}'| awk-F'"'{print $2}'`

Echo "UUID=$uid / data1 xfs defaults 0" > > / etc/fstab
