Prepare the hard drives

In this example we create a RAID just for storage, so we only have one Partition on each drive.

Code: GPT partition layout for RAID

/dev/sdb 2.7 TiB FD00 Linux RAID /dev/sdc 2.7 TiB FD00 Linux RAID

# gdisk /dev/sdb

Code: gdisk commands

Command (? for help): p Disk /dev/sdb: 5860533168 sectors, 2.7 TiB [...] n 1 enter enter fd00 p w Y

Create the RAID array

RAID 1

# {{{1}}}

RAID 5

# {{{1}}}

Checking the progress

# cat /proc/mdstat

# mdadm --detail /dev/md0

# mdadm --examine /dev/sdb1

fstab

Code: /etc/fstab
