Creating RAID config:

• Create RAID during installation of the OS or after using Webmin

• Create a file system on the RAID drive

• /dev/mdX → X = your drive number it could be any number

• After file system is created mount the drive in one of the locations on the OS drive so that it is accessible by all the applications

Manually Mount a USB Drive

A USB storage device plugged into the system usually mounts automatically, but if for some reasons it doesn't automount, it's possible to manually mount it with these steps.

1. Press Ctrl+Alt+T to run Terminal.

2. Enter sudo mkdir /media/usb to create a mount point called usb.

3. Enter sudo fdisk -l to look for the USB drive already plugged in, let's say the drive you want to mount is /dev/sdb1.

4. To mount a USB drive formatted with FAT16 or FAT32 system, enter:
   sudo mount -t vfat /dev/sdb1 /media/usb -o uid=1000,gid=100,utf8,dmask=027,fmask=137
   
   

5.  OR, To mount a USB drive formatted with NTFS system, enter:
   sudo mount -t ntfs-3g /dev/sdb1 /media/usb

To unmount it, just enter sudo umount /media/usb in the Terminal.
