To mount USB mass storage device on CentOS 7, you need to add a package repository first and install some exfat utilities. |
Check your attached devices by fdisk
In my case, I am planning to mount 10T Harddisk, and it it shown as 9.1T in /dev/hda2 like below when I run fdisk -l

Install exfat utilities
In order to mount that device in exfat, you will need to add package repository for exfat as following

Mount
Create a folder in some nice location
...
Format and label
Format in exfat
| Code Block |
|---|
# mkfs.exfat /dev/sda2
|
Once formatting is started, you will see below results
| Code Block |
|---|
mkexfatfs 1.2.7 Creating... done. Flushing... done. File system created successfully. |
And you can simply mount it as followingGive label to partition as following - this is very import !!
| Code Block |
|---|
mount# exfatlabel /dev/sda2 /mnt/10TEX_PART |
Mount
Create a folder in some nice location
| Code Block |
|---|
# mkdir /mnt/10T |
And you can simply mount it as following
| Code Block |
|---|
mount /dev/sda2 /mnt/10T |
Auto-mount USB mass storage while booting
The first thing what I tried is to get UUID for the required disk partition by ls -al /dev/disk/by-uuid/ as following
| Code Block |
|---|
# ls -al /dev/disk/by-uuid/ |
Then you will see the table like below
| Code Block |
|---|
drwxr-xr-x 2 root root 140 Jul 13 13:58 .
drwxr-xr-x 8 root root 160 Jul 13 13:58 ..
lrwxrwxrwx 1 root root 10 Jul 13 13:58 0C80-DEDB -> ../../sda1
lrwxrwxrwx 1 root root 10 Jul 13 13:58 2e3fddc0-f6db-4b5b-a4b1-f8cd51da5095 -> ../../dm-1

lrwxrwxrwx 1 root root 10 Jul 13 13:58 dd68fbad-bf99-4fd7-aee4-76fb8c0323f9 -> ../../sda2 |
In my case, I tried to mount /dev/sda2 above and its UUID is 636e9a0f-5fdf-43ca-8158-8f1af0a84f29, and I it at /etc/fstab like below:
| Code Block |
|---|
UUID=9096-6D1E /mnt/10T ext4 defaults 0 0 |
What I intended is to mount the partition having the UUID like above to /mnt/10T, and it worked as I wanted.
