NOTE: UAS and UAI are deprecated in CSM 1.5.2 and will be removed in CSM 1.6
If a user attempts to create a UAI in the legacy mode and cannot create the UAI at all, a good place to look is at volumes. Duplicate mount_path specifications in the list of volumes in a UAI will cause a failure that looks like this:
ncn-m001-cray uas create --publickey ~/.ssh/id_rsa.pub
Example output:
Usage: cray uas create [OPTIONS]
Try 'cray uas create --help' for help.
Error: Unprocessable Entity: Failed to create deployment uai-erl-543cdbbc: Unprocessable Entity
Currently, there is not a lot of UAS log information available from this error (this is a known problem), but a likely cause is duplicate mount_path specifications in volumes. Looking through the configured volumes for duplicates can be helpful.
ncn-m001-cray uas admin config volumes list | grep -e mount_path -e volumename -e volume_id
Example output:
mount_path = "/app/broker"
volume_id = "1f3bde56-b2e7-4596-ab3a-6aa4327d29c7"
volumename = "broker-entrypoint"
mount_path = "/etc/sssd"

Looking through this list, the mount path for the volume named delete-me and the mount path for the volume named optforge are the same. The obvious candidate for deletion in this case is delete-me, so it can be deleted.
ncn-m001-cray uas admin config volumes delete 7b924270-c9e9-4b0e-85f5-5bc62c02457e
Example output:
mount_path = "/opt/forge"
volume_id = "7b924270-c9e9-4b0e-85f5-5bc62c02457e"
volumename = "delete-me"
