Modifying the Mount Directory

#df-H (View partition status and data disk name)

# mkdir/data (if no data directory is created, this step is skipped)

# umount/home (unmount the hard drive Mounted home directory)

# Mount/dev/sdb1/data (Mount to data directory)

# vi/etc/fstab (edit Fstab file modified or added so that it can be mounted automatically after reboot)
/dev/sdb1/data ext3 Auto 0 0

If "Device is busy" appears when unmount, it proves that the original Mount directory is being used and that the relevant process needs to be available to see which processes are using the following command:

Fuser-m-V/DSG
