Soft RAID50 Making

===== steps to create RAID50 ======

1. Create a partition
[Email protected] ~]# Fdisk/dev/sdb
[Email protected] ~]# FDISK/DEV/SDC
[Email protected] ~]# FDISK/DEV/SDD
[Email protected] ~]# FDISK/DEV/SDE
[Email protected] ~]# FDISK/DEV/SDF
[Email protected] ~]# FDISK/DEV/SDG
[Email protected] ~]# FDISK/DEV/SDH
[Email protected] ~]# FDISK/DEV/SDI

2. Check the raid version and help
[Email protected] ~]# Mdadm--verson
[Email protected] ~]# mdadm-v
[Email protected] ~]# Mdadm--help

3. Check if the system supports raid
[Email protected] ~]# cat/proc/devices
[Email protected] ~]# Cat/proc/devices | grep MD
[Email protected] ~]# ls/dev/md*

4. Create Raid5
[Email protected] ~]# mdadm-c/dev/md0-l5-n3-x1/dev/sdb1/dev/sdc1/dev/sdd1/dev/sde1

[Email protected] ~]# mdadm-c/dev/md1-l5-n3-x1/dev/sdf1/dev/sdg1/dev/sdh1/dev/sdi1
5. View RAID5
[Email protected] ~]# ls/dev/md*
[Email protected] ~]# Mdadm-ds
[Email protected] ~]# mdadm-ds/dev/md0
[Email protected] ~]# MDADM-DS/DEV/MD1

6. Format RAID5 (This step can be omitted)
Note: You can use RAID5
[Email protected] ~]# mkfs-t ext4/dev/md0
[Email protected] ~]# mkfs-t ext4/dev/md1

7. Create RAID50
Principle: Generate 1 Raid5 of 2 x Raid0
[Email protected] ~]# mdadm-c/dev/md2-l0-n2/dev/md0/dev/md1
[Email protected] ~]# ls/dev/md*

8. Formatted RAID50
[Email protected] ~]# mkfs-t EXT4/DEV/MD2

9, Mount use
[Email protected] ~]# mkdir/www
[Email protected] ~]# mount/dev/md2/www/
[Email protected] ~]# DF-HT
