Increase C drive size of windows server on AWS

This post describes how to Increase C drive of Windows server on AWS

 

 

Step 1: Note current C drive space on windows server (in this e.g. it is 30 GB)

 

 

 

 

 

Step 2: Login to AWS console. Click on root device of instance for which C drive needs to be increased and note down EBS ID of volume

 

 

 

Step 3: Search volume by volume id noted in previous step and  take snapshot of volume by right clicking on the volume

 

 

 

Step 4: Enter name and description of snapshot

 

Step 5: search snapshot and Create new volume by right clicking snapshot

 

 

Step 6: Select type of volume

Select size (mention the new size that you want). I have increased by 10 GB hence new size is 40 GB

Select availability zone. Availability zone should be same zone in which instance is available.

NOTE: You cannot attach volume created in another availability zone then from instance

 

 

 

 

Step 7: Note EBS ID of new volume created

 

 

 

Step 8: After shutting down the instnace.

Right click the volume and detach the old root volume from instance where it is attached (Old volume 30 GB)

Now instance will not have the volume

 

Step 9:   Attach new volume which we have created from snapshot (This volume is with increased size)

 

 

Enter instance ID of the instance where volume need to be attached add device name

NOTE: Root volume should be named as /dev/sda1

 

 



Step 10:  Verify new volume is attached to the instance

 

 

 

 

 

 Step 11: Increase C drive size by extending the volume from inside windows server.
