Create an ESB Volume

aws ec2 create-volume --availability-zone=eu-west-1a --size=10 --volume-type=gp2

Making an EBS Volume Available for Use

I need to do that to use the storage and not fill up the root partition.

Code to apply the procedure automatically is available in em.

Organizatorium

Even if the dedicated disk has 800GB, the default partitions are undersized. I need to understand this better, but this is what I did:

lsblk
NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
xvda    202:0    0  800G  0 disk 
├─xvda1 202:1    0    1M  0 part 
├─xvda2 202:2    0    6G  0 part /

There's a lot of space (790+GB) that is not allocated to any partition.

gdisk /dev/xvda

p (print partions)

n (create new partion)

Partition Number: 3

First sector .. etc

Allocate all, then 'w' and then reboot - otherwise /dev/xvda3 won't be visible.
