In terraform I am attaching a bunch of volumes to an EC2 instance. I have specified the devices in the terraform as /dev/sda - /dev/sdac. All of the disks are built and attached for /dev/sda - /dev/sdz but once it gets to /dev/sdaa it errors out.

Error: Error attaching volume (vol-079ee9fac3f0a2ec4) to instance (i-072bff999f2ce6780), message: "Value (/dev/sdaa) for parameter device is invalid. /dev/sdaa is not a valid EBS device name.", code: "InvalidParameterValue"

Is there a limit on the number of volumes that anyone knows of?

I believe the next one after /dev/sdz is /dev/xvdba. See https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/device_naming.html
