I've got an EC2 instance running Ubuntu and want to attach some 50-60 EBS volumes to it. However, the EC2 console says I can use only /dev/sdf through /dev/sdp, so I'm limited to 11 volumes. Is there a way around this limitation?
Any specific reason you want to attach that many separate volumes to the instance?
I believe what you want are lots of partition in your system. But for that you don't need that much EBS volumes to be attached to the instance.
You can simply attach a bigger Volume and then partition it at the OS level, using utilities like fdisk or parted.
Please let me know if there is any specific reason you want to attach that many volumes or else this solution should work.
The cause for this particular question is apparently the misleading nature of the EC2/EBS web console. It seems to explicitly say that you can't attach past sdp (xvdp), but if you just ignore its suggestions and manually type in sdq, it will probably just work.
The matter of higher limits than that is discussed at http://stackoverflow.com/questions/11042413/what-is-the-max-number-of-attached-volumes-per-amazon-ec2-instance
