fstab vs. Gparted

[JerryW]

So, I installed a new solid state drive and have been pondering moving my "home" folder to it. When I do a "lsblk", I get:

Code: Select all

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931.5G  0 disk 
sdb      8:16   0 465.8G  0 disk 
├─sdb1   8:17   0   953M  0 part /boot
├─sdb2   8:18   0  24.8G  0 part /
├─sdb3   8:19   0   7.8G  0 part [SWAP]
└─sdb4   8:20   0 432.2G  0 part /home
sr0     11:0    1  1024M  0 rom  

The above partitioning scheme is what I see using GPARTED
sda is apparently my new drive, installed but nothing further done.

When I look at FSTAB (/etc/fstab - - gedit) I get:

Code: Select all

# /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/sda2 during installation
UUID=067258bb-4967-4f00-b6a5-379b038f389f /               ext4    errors=remount-ro 0       1
# /boot was on /dev/sda1 during installation
UUID=243c5d8c-7fbe-4640-94e0-31654f08d855 /boot           ext4    defaults        0       2
# /home was on /dev/sda4 during installation
UUID=856f7c0f-de45-4597-9595-f8d116084b11 /home           ext4    defaults        0       2
# swap was on /dev/sda3 during installation
UUID=35fda864-d74d-4ddd-8285-995d8b603905 none            swap    sw              0       0

So fstab, to me, looks like it thinks all my stuff is on sda...but it's actually on sdb. What am I missing?

What am I missing?

"/home was on". The system uses the partition UUIDs and they haven't changed.

Ahhh, thanks Andy

I was going to move my home folder to my new solid-state drive using:
https://www.howtogeek.com/442101/how-to ... ard-drive/

the last step was an edit of the fstab - and that's where my knowledge came to a halt. I may wait
till I do a complete clean install - and use that opportunity to move my backed-up home folder to the
new solid state drive.

Thanks again

That would work, but he makes it hard work by using the terminal nearly all the way. You can setup the new drive - create a partition table, create partitions, with gparted, it's a lot easier.

While the changes to fstab are simple, mess it up and you will end up with a system that won't boot. If you proceed make sure you have a mint install stick/DVD to hand so that you can boot it if necessary to delete the fstab you modified and rename the copy you made back to fstab.

You already have a separate /home partition so all you would need to do in fstab is change the UUID so it points at the new partition on the other drive.
change

Code: Select all

UUID=856f7c0f-de45-4597-9595-f8d116084b11 /home ext4 defaults 0 2

to

Code: Select all

UUID=newUUID /home ext4 defaults 0 2

You get the new UUID by typing blkid in a terminal and copy/pasting.

I see you have a separate /boot partition, have you got an encrypted install?
