Running Ubuntu 18.04 64-bit on a system with 2 hard drives. System is dual boot: Win-10 & Xubuntu. The PC has 2 disk drives: a small boot flash drive with a 14.7 Gb Partition for Linux and a 169 Gb partition for Linux on the 2nd data drive.

Ubuntu installed itself completely to the 14.7 Gb Partition & that's where the $Home directory was mounted at /. Both OSes booted fine but the 2nd drive was left as 169 GB: unallocated space. Used GParted boot disk to set this 169 Gb as a primary partition formatted ext4 following the article Partitioning/Home/Moving to move my home to the new home on the "big" 169 GB partition.

All seemed to go well but then the 169 Gb partition "disappeared". I can still find it under blkid:

└─sdb2 ext4     Sam Evo P2    169G /home

But when I try to mount it per my fstab, it simply isn't mounted. It is the sdb2 ext4 at the bottom of the listing. Here's my /etc/fstab:

# /etc/fstab: static file system information.
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda6 during installation
# original filesystem

# new 169 Gb partition label Sam Evo P2

The wiki "Moving Home" article seems to neglect mentioning exactly how to mount both partitions. The OS boot partition is under: sda6 while the new /home is under sdb2.

Any suggestions on how I can complete the move and load my new $Home partition?

Responding to the question about how I know my new partition is not mounted

Below is my Desktop. Before I edited fstab, it showed 3 filesystems: "Sam Evo P2" which is my 1TB Samsung Evo 860 drive: Partition 2 {ext4}. This partition was mounted under /home. It also showed the others: Sam 860 Evo + SSHD_boot } both of these are working fine as NTFS Windows partitions.

Now as you can see the "Sam Evo P2" is gone and hovering over File System shows I've used 98% of the 15.6 Gb.

file system no space

However if I go into the filesystem /home/john then it appears that I've actually mounted that 169Gb partition {here it says 177.5 Gb}.

file system with space

Note that /old_home is a copy of my home directory from when I only mounted the 15.6 Gb partition. Eventually I should delete it if my system works. Does this mean that my system is actually working???

    Your fstab shows it should be mounted. And your lsblk shows it mounted. Are you booted into your install? You cannot mount it again if already mounted. – oldfred May 12 '20 at 20:56

    Your lsblk-output shows sdb2 mounted at /home, why do you think it's not mounted? What do you mean with the 169 Gb partition "disappeared"? – mook765 May 12 '20 at 20:57

    Looks fine as far as I can see. – mook765 May 12 '20 at 22:38

    If you used the rsync-command according to the guide you used, your data should exist in the new partition already, since your background image and theme are present it looks like you don't need to do that. – mook765 May 13 '20 at 1:05

    Did you solve this? It might be helpful if you could post an answer explaining what happened – Zanna Jun 4 '20 at 9:32
