Mount Two Drives to One Linux Dir

In a Linux system, you can mount two hard drives to the same directory using LVM (Logical Volume Management).

The following are the specific steps:

1. Show block devices.
2. List all the partitions on the system.
3. initialize a physical volume

pvcreate /dev/sdb
pvcreate /dev/sdc

1. create a volume group

vgcreate myvg /dev/sdb /dev/sdc

1. create a logical volume

lvcreate -L 100G -n mylv myvg

1. Create a new file system

mkfs.ext4 /dev/myvg/mylv

1. Create a directory for mounting the logical volume, for example:

mkdir /mnt/mylv

1. To climb or scale a mountain.

mount /dev/myvg/mylv /mnt/mylv

1. The file named /etc/fstab

/dev/myvg/mylv /mnt/mylv ext4 defaults 0 0

After completing the above steps, both hard drives will be mounted in the same directory and can be used together.
