Check Existing Filesystems on RAID Arrays: First, check if there are existing filesystems on your RAID arrays (md0 and md1). This will determine whether you need to create new filesystems.
sudo file -s /dev/md0
sudo file -s /dev/md1
Create Filesystems (If Necessary): If the RAID arrays don't have filesystems, you'll need to create them. Below, we're using ext4, but you can substitute it with your preferred filesystem type.
sudo mkfs.ext4 /dev/md0
sudo mkfs.ext4 /dev/md1
Create Mount Points: You need directories to serve as mount points for your filesystems.
sudo mkdir /mnt/md0
sudo mkdir /mnt/md1
Mount the Filesystems: Mount the newly created filesystems to the mount points.
sudo mount /dev/md0 /mnt/md0
sudo mount /dev/md1 /mnt/md1
Auto-Mount at Boot: To ensure these filesystems are mounted automatically at boot, add them to /etc/fstab. First, open the file with a text editor, such as nano:
sudo nano /etc/fstab
#Then, add the following lines to the end of the file:
/dev/md0 /mnt/md0 ext4 defaults 0 0
/dev/md1 /mnt/md1 ext4 defaults 0 0
#Save and close the file. To check if your fstab file is correct and will not cause boot issues, you can simulate its effect:
sudo mount -a
#This command attempts to mount all filesystems mentioned in fstab.
If any of your remaining NVMe SSDs need to be mounted or have their partitions mounted, follow similar steps:
nvme6n1 259:2 0 3,6T 0 disk (4 TB M.2 NVMe SSD WD Black SN850X)
Create a Partition (if necessary): You might need to create partitions using tools like fdisk or parted. For a simple, single partition setup, you can use:
sudo fdisk /dev/nvme0n1
sudo fdisk /dev/nvme1n1
sudo fdisk /dev/nvme2n1
#设备不包含可识别的分区表。
#The size of this disk is 3,5 TiB (3840755982336 bytes). DOS partition table format cannot be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).
命令(输入 m 获取帮助): g
已创建新的 GPT 磁盘标签(GUID 分区表)。
命令(输入 m 获取帮助): n
分区号 (1-128, 默认 1):
起始扇区 (2048-7501476526, 默认 2048):
最后扇区, +/-扇区 or +/-size{K,M,G,T,P} (2048-7501476526, 默认 7501476526):
创建了一个新分区 1,类型为“Linux filesystem”,大小为 3,5 TiB。

已完成。
And follow the prompts to create a new partition. Create a Filesystem:
sudo mkfs.ext4 /dev/nvme0n1p1 # Assuming the partition created is nvme0n1p1
sudo mkfs.ext4 /dev/nvme1n1p1
sudo mkfs.ext4 /dev/nvme2n1p1
sudo mkfs.ext4 /dev/nvme3n1p1
sudo mkfs.ext4 /dev/nvme4n1p1
sudo mkfs.ext4 /dev/nvme6n1p1
Mount the Filesystem: First, create a mount point, for example:
sudo mkdir /mnt/nvme0n1p1
sudo mkdir /mnt/nvme1n1p1
sudo mkdir /mnt/nvme2n1p1
sudo mkdir /mnt/nvme3n1p1
sudo mkdir /mnt/nvme4n1p1
sudo mkdir /mnt/nvme6n1p1
Then, mount the partition:
sudo mount /dev/nvme0n1p1 /mnt/nvme0n1p1
sudo mount /dev/nvme1n1p1 /mnt/nvme1n1p1
sudo mount /dev/nvme2n1p1 /mnt/nvme2n1p1
sudo mount /dev/nvme3n1p1 /mnt/nvme3n1p1
sudo mount /dev/nvme4n1p1 /mnt/nvme4n1p1
sudo mount /dev/nvme6n1p1 /mnt/nvme6n1p1
Add to fstab for Auto-Mount:
/dev/nvme0n1p1 /mnt/nvme0n1p1 ext4 defaults 0 0
/dev/nvme1n1p1 /mnt/nvme1n1p1 ext4 defaults 0 0
/dev/nvme2n1p1 /mnt/nvme2n1p1 ext4 defaults 0 0
/dev/nvme3n1p1 /mnt/nvme3n1p1 ext4 defaults 0 0
/dev/nvme4n1p1 /mnt/nvme4n1p1 ext4 defaults 0 0
/dev/nvme6n1p1 /mnt/nvme6n1p1 ext4 defaults 0 0
sudo mount -a
