v2.4.0.0 AMI Parsing Error Code Reference Slurm

Parsing an AMI and validating the image’s ability to connect with the HPC scheduler can be challenging task depending on the requirements of the environment.

Note: If SELINUX is not already disabled in the target AMI, it will need to be disabled.

Error Codes from Parsing AMIs

The following table lists error code and information about them.

Code	Error	How To Debug

Code	Error	How To Debug
1	Catch all error code for unhandled errors. Added as a safety net in case any unhandled errors occur.	If available, check the logs or script output for more details on the error. This applies to all error codes.
100	Could not get metadata, such as SGs, subnet, AZ, and/or could not determine the AMI ID of the AL2 AMI.	Ensure metadata service and EC2 API are available and the required IAM permissions for the script are granted. Another potential issue is that the `aws` CLI command is not in the `PATH` or that the aws CLI has been installed through yum. It should be installed through these instructions instead Installing or updating to the latest version of the AWS CLI - AWS Command Line Interface
101	Could not create instance from the AMI that should be parsed.	Potential issues: `ssh-keygen` was not able to generate a public key from a private key. If a `--private- key-file` was specified ensure that the key file is valid. The userdata could not be generated properly, if a `--public-key-file` was specified ensure it exists. The EC2 `run-instances` call failed. This could be due to a lack of permissions or invalid parameters such as the specified AMI ID or `--key-name`
102	Could not get root volume ID of primary instance.	Ensure required IAM permissions for the script are granted.
103	Could not boot secondary AL2 instance for EBS based image.	See error code 101, the `run-instances` call could have failed.
104	Could not wait for instances to reach ready state.	Ensure required IAM permissions for the script are granted. Alternatively there could be an issue with the instances not being able to reach a ready state. In the AWS console look for instances tagged `parseAMI` to inspect the instances further.
105	Failed to ssh to primary instance.	Ensure that network traffic is allowed between instances assigned the security groups of the instance running the script In rare cases SSH to the instance will fail due to timeout if the AMI is very slow to boot up, or if it slow to respond to SSH calls
106	Could not get `/proc/cmdline` of primary instance.	Some AMIs might mount the `/home` directory after booting, eclipsing the SSH keys used by default. If that is the case retry running the script with the `private_key_file` and `username` options that match the user for the mounted directory.
107	The wildcard generated from the `BOOT_IMAGE` parameter to determine the initrd of the AMI is not valid.	Similar to error code 115, inspect the log output for `init_wcard`. If the wild card is not a path an issue with the underlying `BOOT_IMAGE` parameter or an issue with extracting the path properly.
108	Command to find initrd files with the init wildcard failed.	See 107
109	No valid init file could be found.	See 107. If the wildcard is valid inspect an instance booted from the AMI and verify that valid init images are present in the `/boot` directory.
110	Could not change init file permissions.	Check log output to see why changing the permission failed.
111	Could not copy init file from booted instance to instance running the script.	Make sure permissions to copy to the local directory are granted.
112	Running the script with commands to update the instance failed.	Required Ensure that the current user has permission to write files. Optional Ensure that the specified script exists and can be executed within 5 min.
113	Could not get snapshot of root volume of the booted instance.	Ensure required IAM permissions are granted. There could be an issue with the booted instance(s) and the root volume. In the AWS console look for instances tagged `parseAMI` to inspect the instances further.
114	Could not save example create-vm command to file.	Ensure the current user has permission to write files.
115	Could not find the `BOOT_IMAGE` parameter in the `/proc/cmdline` output.	Inspect the log output to see what is logged for `boot_params`, alternatively inspect the `/proc/cmdline` of an instance of the AMI to see whether the parameter does not exist or there was an issue picking it up. It could indicate an issue with the underlying AMI.
116	Caught interrupt signal that terminated the script execution.	N/A
117	Could not create JSON manifest file containing all the image information.	Ensure required IAM permissions are granted. Ensure the current user has permission to write files.
118	Could not generate tmp SSH key to gain access to the booted instance.	Verify that keys can be generated on the current instance with `openssl`.
