Setup HDD to mount automatically

[stanislas-brossette]

Hello,
I recently build a PC and installed ubuntu 18.04 on it. I installed 2 HDD in it, but only one is automatically mounted.
I'd like the second one to be mounted as well. Any help appreciated.
Here is the output of sudo blkid

/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
/dev/loop2: TYPE="squashfs"

And here of sudo fdisk -l

And cat /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/sda2 during installation

# swap was on /dev/sda3 during installation
UUID=821db62e-17ad-40da-9e8f-6c9a7a7b3c61 none swap sw 0 0

I assume that I need to add the correct line in /etc/fstab, but not sure how to write that line.
Thanks

Your second 1TB drive shows in your fdisk output and it has no partitions or filesystems. You mount filesystem on a device or more commonly, on a partition on a device, so there is nothing to mount. Create a partition or several based on your needs and create a filesystem on it which you can do from the installer with GParted. If you want them to moun on boot, you need an entry in the /etc/fstab file for each partition.

After you get the disk partitioned and partitions formatted, you can follow this short description of how to do this:

You can copy the line below and paste into /etc/fstab at bottom. Change the UUID to the UUID of the data partition (file system) on the 2nd drive that you want to mount. On startup, this example mounts the ext4 file system matching the given UUID at /mnt/Data


UUID=c3121154-ee33-418b-8c43-10377841e3c2 /mnt/Data ext4 defaults 0 2

Read UUID for your partitions (file systems) from this command:


lsblk -o name,UUID

After reboot and checking that the automount worked, change owner and group of the mount point (/mnt/Data) to you user name. Then you can use it.

If your user name is name,

sudo chown -R name:name /mnt/Data

Also since sda is gpt partitioned better to use gpt partitioning for sdb.

I have created my gpt partitions with gparted. Under device, create partition table, advanced, choose gpt not the default msdos (MBR) partitioning. Then add the partitions you want.
I do like to have another / (root) partition of 25GB for test or experimental installs. And I want an ESP - efi system partition on every drive, even if not directly used by Ubuntu default installs.

Use ext4, but you will have to give yourself ownership & permissions.

Create mount point, mount & edit fstab from user Morbius1 in Post # 6 - suggest using templates instead.
Good example of manually mounting, except I prefer /mnt/xxx as location to mount to.
