Amazon EBS Snapshots in the EU-West Region

AWS has discovered a bug in their software that cleans up EBS snapshots in the EU West region. They are contacting customers that have snapshots affected by this bug. Here is the email that some of our customers are receiving:

 

Hello,

We've discovered an error in the Amazon EBS software that cleans up unused snapshots.  This has affected at least one of your snapshots in the EU-West Region.

During a recent run of this EBS software in the EU-West Region, one or more blocks in a number of EBS snapshots were incorrectly deleted. The root cause was a software error that caused the snapshot references to a subset of blocks to be missed during the reference counting process. This process compares the blocks scheduled for deletion to the blocks referenced in customer snapshots. As a result of the software error, the EBS snapshot management system in the EU-West Region incorrectly thought some of the blocks were no longer being used and deleted them. We've addressed the error in the EBS snapshot system to prevent it from recurring.

We have now disabled all of your snapshots that contain these missing blocks. You can determine which of your snapshots were affected via the AWS Management Console or the DescribeSnapshots API call. The status for any affected snapshots will be shown as "error."

We have created copies of your affected snapshots where we've replaced the missing blocks with empty blocks. You can create a new volume from these snapshot copies and run a recovery tool on it (e.g. a file system recovery tool like fsck); in some cases this may restore normal volume operation. These snapshots can be identified via the snapshot Description field which you can see on the AWS Management Console or via the DescribeSnapshots API call. The Description field contains "Recovery Snapshot snap-xxxx" where snap-xxx is the id of the affected snapshot. Alternately, if you have any older or more recent snapshots that were unaffected, you will be able to create a volume from those snapshots without error. For additional questions, you may open a case in our Support Center: https://aws.amazon.com/support/createCase

We apologize for any potential impact this might have on your applications.

Sincerely,
AWS Developer Support

Migrating EBS instances to an AMI in a different region

You have an EBS instance running in US east region. But you want to migrate this instance to an AMI in EU, for disaster recovery, testing, whatever. And you say want to do this simply and without major contortions, preferably via a GUI. We hear you :-) Ylastic now has the ability to migrate an EBS linux instance to an AMI in a region of your choice. Pick a few options, and click a button.

Simpler migration for Ubuntu based AMIs between EC2 regions

Ubuntu is a very picky about the kernels used in EC2, especially starting with Lucid Lynx. This makes migration between regions a bit painful as you need to know the right kernel to use (32 or 64 bit) when you migrate an AMI between different regions. In Ylastic, we have a simple gui based migration, but you had to pick a kernel in the target region for any recent ubuntu based AMI in order to launch the migration. Not any more :-) We now automatically pick a kernel that will work for your migrated AMI in the target region.

Distro2

You just need to make sure you pick the right flavor of Ubuntu :-)

Distro3
