Scan all existing hosts with a one-liner:
for host in /sys/class/scsi_host/*; do echo "- - -" | sudo tee $host/scan; ls /dev/sd* ; done
fdisk /dev/sdb
m to menu
n to new partition
w to write
mkfs.ext4 /dev/sdb1 to format
Resize disc:
To make the kernel aware, one can issue the following command as root:
echo 1 > /sys/class/block/sdb/device/rescan
parted /dev/sdb
print
resizepart 1
quit parted
sudo partprobe
Resize File system
umount /dev/block_device
e2fsck -f /dev/block_device
resize2fs /dev/block_device
