Growing Amazon EBS Volume sizes?

You can grow the storage, but it can't be done on the fly. You'll need to take a snapshot of the current block, add a new, larger block and re-attach your snapshot.

You can't simply 'bump in' more space on the fly if you need it, but you can resize the partition with a snapshot. Steps do to this: unmount ebs volume create a ebs snapshot add new volume with more space recreate partition table and resize filesystem mount the new ebs volume Look at aws.amazon.com/ebs/ - EBS Snapshot: Snapshots can also be used to instantiate multiple new volumes, expand the size of a volume or move volumes across Availability Zones. When a new volume is created, there is the option to create it based on an existing Amazon S3 snapshot.In that scenario, the new volume begins as an exact replica of the original volume.

By optionally specifying a different volume size or a different Availability Zone, this functionality can be used as a way to increase the size of an existing volume or to create duplicate volumes in new Availability Zones. If you choose to use snapshots to resize your volume, you need to be sure your file system or application supports resizing a device.

As long a you are okay with a few minutes of downtime, Eric Hammond has written a good article on resizing the root disk on a running EBS instance: alestic.com/2010/02/ec2-resize-running-e....

I have written a tutorial to grow the size of your ebs volume at - aws-musings.com/how-to-expand-your-ebs-v....

1 thanks for posting this, it was most helpful. – Chris J Jan 5 at 18:45 +1 again... works like a charm – Jai Nov 26 at 15:17.

You can now do this through the AWS Management Console. The process is the same as in the other answers but you no longer need to go to the command line.

The console may be able to resize the volume, but how does it handle resizing of the partition inside of the volume, especially if it is of a type like XFS, BRTFS, etc? – Riyad Kalla Nov 4 at 16:40.

BTW: As with physical disks, it might be handy to use LVM; ex: davelachapelle.ca/guides/ubuntu-lvm-guide/ centos.org/docs/5/html/Cluster_Logical_V... Big advantage: It allows adding (or removing) space dynamically. It can also easily be moved between/among instances. Caveats: it must be configured ahead of time a simple JBOD setup means you lose everything if you lose one "disk.

Use command "diskpart" for Windows OS, have a look here : Use support.microsoft.com/kb/300415 Following are the steps I followed for a non-root disk (basic not dynamic disk) Once you have taken a snapshot, dismounted the old EBS volume (say 600GB) and created a larger EBS volume (say 1TB) and mounted this new EBS volume - you would have to let Windows know of the resizing (from 600GB to 1TB) so at command prompt (run as administrator) diskpart. Exe select disk=9 select volume=Z extend my disk 9,volume labelled Z, was a volume of size 1TB created from an ec2-snapshot of size 600GB - I wanted to resize 600GB to 1TB and so could follow the above steps to do this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
