Increase EC2 Volume without Changing Public IP

Question

My Instance Disc Space is about to fill up .

1) If I increase the volume it requires stop/start of instance . If I Stop/Start the instance . My Public IP will change .

2.) I don't have Elastic IP applied to it .If i associate a new Elastic IP . My Public IP will change to the Elastic IP.

So basically I want to increase My Disc Space Without changing my Public IP of the Instance.

Yes i get it . But I didn't knew that they where changing the ip addresses on every start/stop procedure . Nor did i knew about the Elastic Ip's — Vikrant Vir Bhalla, Jun 10 '15 at 09:49
Once i switch to a elastic ip it will again change to new ip address . That is what i dont want . — Vikrant Vir Bhalla, Jun 17 '15 at 07:12

Easiest thing to do is to add a second/new EBS volume to your existing/running EC2 instance, then you can either move some of the stuff that does not need to be on the primary volume to the second volume, or else if possible redirect the new data coming in to the newly added volume.

Not knowing what is filling up your disk, I don't know which is a better option, or if either is an option for you.

EDIT: In response to comment then I would still recommend that you add a new volume to the server, and then move your MongoDB database to that volume.

The Problem will still be there as when i will create a new volume i have o stop the instance . When i stop the instance the public ip will change . – Vikrant Vir Bhalla Jun 09 '15 at 09:44
I have attached and detached volumes from running instances all the time. What AMI are you running? – E.J. Brennan Jun 09 '15 at 09:57
Also please let me know a link of any tutorial which attaches and detaches volumes from running instance . So that the public IP Does Not change . – Vikrant Vir Bhalla Jun 09 '15 at 11:34

Now you have an option to change the volume of your Instance on the fly.With Elastic Volumes (EBS), you can dynamically modify the size, performance, and volume type of your Amazon EBS volumes without detaching them.

Once you do that make sure to increase the volume from within the OS, using diskmgmt.msc (Windows)
