Linux system to re-mount/home to another hard disk or partition

Not planning at first, causing the/home space shortage, plus the partition table is not GPT, resulting in the inability to expand more than 2T, so it is necessary to re-partition a larger hard disk to/home.

1. Partition and format the newly mounted 4T hard drive

2. Create a Directory

sudo mkdir/media/home

3. Mount the/DEV/SDB1 to the/media/home

sudo mount/dev/sdb1/media/home

4. Synchronize/home to/media/home, the synchronization time depends on the size of the data, it is recommended to operate when the system is idle

sudo rsync-axs/home/. /media/home/.

5. Rename/home after synchronization is complete

sudo mv/home/home_old

6. New/Home

sudo mkdir/home

7. Cancel/DEV/SDB1 Mount

sudo umount/dev/sdb1

8. Re-mount/DEV/SDB1 to Home

sudo mount/dev/sdb1/home

9. View/DEV/SDB1 's UUID

Blkid

10. Copy the UUID and modify the/etc/fstab file to automatically mount the boot.

sudo gedit/etc/fstab

At the end of the file, add the following:

# home 4T

Uuid=8da46012-ab9c-434f-a855-2484112fd1a7/home ext4 Nodev,nosuid 0 2

11. Restart the system after saving to view the partition mount status

Df–h

12. Delete/home_old after confirming everything is OK

sudo rm-rf/home_old

At this point, the work to add space to/home is complete.

The Linux system re-mounts the/home to another hard disk or partition
