1. Create and format a hard disk partition

1.1. View detected devices of class "DISK"

sudo lshw -C disk

1.2. View existing partition table(s)

sudo fdisk -l

1.3. Edit the partition table for my chosen device (in this case, "sdb")

sudo fdisk /dev/sdb

Changes will remain in memory only, until you decide to write them. Be careful before using the write command.

Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0x1c8c9d78.

1. Type n and press Enter.
2. Type p and press Enter.
3. Type 1 and press Enter.
4. Press Enter to accept the default first sector. 5.** Press Enter** to accept the default last sector.
5. Type w and press Enter to write the changes to disk. You should now have a new partition called sdb1.

Display the new partition table:
sudo fdisk -l

/dev/sdb1 wird angezeigt

2. Format new partition as type ext4

2.1. Format the new partition

sudo mkfs -t ext4 /dev/sdb1

answer:
mke2fs 1.44.1 (24-Mar-2018) Creating filesystem with 4194048 4k blocks and 1048576 inodes Filesystem UUID: 8a1f9e47-da1f-49f1-999d-b742020d480e Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000

Allocating group tables: done
Writing inode tables: done
Creating journal (16384 blocks): done Writing superblocks and filesystem accounting information: done

2.2. Create a new directory where the new drive will mount into

sudo mkdir /catalogue-data
sudo mount /dev/sdb1 /catalogue-data

Folder /catalogue-data is the data path required by GeoNetwork configured via environment variables environment variables in jetty service

3. Auto-mount filesystem on server start

sudo nano /etc/fstab

add the following line:

# /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>
...
