    <p>I am attempting to create an EBS-backed image from a running instance, similar to <a href="https://stackoverflow.com/questions/2082724/amazon-ec2-swap-root-instance-store-device-with-ebs-device">this post on SO</a>. I'm using primarily these sites as references:</p> <ol> <li><a href="http://thewebfellas.com/blog/2010/4/19/create-an-ebs-boot-volume-from-a-running-instance" rel="nofollow noreferrer">Create a bootable EBS AMI from a running instance</a></li> <li><a href="https://gist.github.com/1004950" rel="nofollow noreferrer">A script to rsync a running Linux OS to an image file</a></li> </ol> <p>I successfully created the EBS volume, ran <code>mkfs.ext3</code> against it (<em>I formatted the whole drive, not a partition -- is this the problem, perhaps?</em>) and used the following <code>rsync</code> command to make a copy of the filesystem:</p> <p><code>rsync --stats -avv --exclude=/root/.bash_history --exclude=/home/*/.bash_history --exclude=/etc/ssh/ssh_host_* --exclude=/etc/ssh/moduli --exclude=/etc/udev/rules.d/*persistent-net.rules --exclude=/mnt/* --exclude=/proc/* --exclude=/tmp/* --exclude=/sys/* --exclude=/dev/* --exclude=/production --exclude=/media / /mnt/ebs-root/</code> </p> <p>(where <code>/media</code> and <code>/production</code> are directories mounted from other EBS volumes, and <code>/mnt/ebs-root/</code> is the new EBS volume which will contain the image)</p> <p>the rsync works well enough, I can unmount the volume, snapshot it, and use the AWS console to make a bootable image... but when it boots, I can't access it over the web/ssh (after changing its elastic IP in the AWS console).</p> <p>I noticed that I might need to edit some files in the new EBS volume (like /etc/fstab) but I'm not sure. Here's the contents of my /mnt/ebs-root/etc/fstab, anyway:</p> <pre><code># Legacy /etc/fstab # Supplied by: ec2-ami-tools-1.3-34544 /dev/sda1 / ext3 defaults 1 1 /dev/sda2 /mnt ext3 defaults 0 0 /dev/sda3 swap swap defaults 0 0 /dev/sdp1 /production ext3 defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 </code></pre> <p>I'm way outside my knowledge base here and hoping someone can point me in the right direction. Thanks in advance.</p>

    1. COCan you clarify: does the new image actually boot successfully (check console log)? Can you ssh to the machine before assigning the EIP? Does your Security Group allow ssh access? Are you unable to ssh after assigning EIP, and are you allowing enough time for the EIP to become effective?

    3. COhere's the system log from amazon: http://pastebay.com/289600 I can't SSH in at all -- before or after assigning EIP. I just tried with the same instance after it's been running overnight so it's probably not waiting.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
