Create a server and mount a block storage device. - ebsarr/packet GitHub Wiki
Goals
- Create a server on packet.net
- Create a block storage volume
- Attach the volume to the server with the packet API and tools
- Create a partion and filesystem on the volume
- Mount the volume to the server
This article assumes that you have installed the packet CLI and set a default profile. Refer to this page to see how to do it.
Create the server
Ubuntu running on a Type 0 server
$ packet baremetal create-device --facility ewr1 --hostname ebsarrtest01 --os-type ubuntu_16_04_image
Provisioning of device successfully started...

Attach the volume to the server
$ packet storage attach-volume --volume-id cbb23532-430b-4bf2-b475-a59c5a8aa4be --device-id 058df2b4-a050-4a5d-89c0-e9d704c9a6de
No error.
Mounting our volume
All remaining commands executed in the server.
The first step is to attach the volume with the packet-block-storage-attach tool. This tool is installed by default on all packet server.
# packet-block-storage-attach
If the volume was successfully attached, you should see the following message before the command ends
Block device /dev/mapper/volume-cbb23532 is available for use
We can now make a partition, build the filesystem and mount it.
# fdisk /dev/mapper/volume-cbb23532
Welcome to fdisk (util-linux 2.27.1).
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 0xd4612f60.

Let's mount it now

Looks alright
Extra: commands to detach the volume and destroy everything.
On the server side
# umount /data1
# packet-block-storage-detach
# exit
Go back to packet CLI
Delete the volume
