So I have a micro instance for my new pet project www.tryperl.com. The micro instance is maxed out and I decided to change it to small.

I followed the accepted answer here on this SO post. However, I cannot get it to work for the life of me!

  • I created snapshot from my small inst volume.

  • I created an AMI from the snapshot and launched a new small instance

  • (My small inst is set in us-east-1b and my micro in us-east-1c, does it make a diff?)

  • The small instance starts and takes forever for status checks and then fails saying Instance reachability check failed.
    When I click view rules on my security group, it says No rules were found in the associated security groups ??! But I'm SURE the security group does have http@80 open!

I'm currently trying a reboot


Should I just stop my micro instance and change it's type? Are there consequences ? I know I'll have down-time. How much downtime will occur??


What else can I try?

What status checks are you referring to? Did you launch the new instance with the same security groups? –  mgorven Feb 11 '13 at 17:28
    
I tried with the same security group and then created a new security group and tried again. No luck. After it goes from pending to running, it loading.. in the status checks column and then after a long time says 1/2 checks failed. On the bottom of the dashboard I see Status Checks => Instance Status Checks And it says reachability problem, try rebooting .. (which I did) –  gideon Feb 11 '13 at 17:38

All in all I just did the following:

  • Right-Click on the instance
    • Instance Lifecycle > Stop
    • Waited for 10 mins
    • Instance Management > Change Instance Type > Changed to Small
    • Instance was back and running in 10-15 mins
    • The domain was giving a could not find for a couple minutes.

So I had some unfortunate down-time and no dinner! Oh well!
