2026-09-08 HistAI Ceph prefix listing
Verified read-only AWS CLI access to the HistAI source-data prefix in the vxdata Ceph bucket.
Work Done
- Used the local AWS CLI profile
ceph to list s3://vxdata/source-data/histai/.
- Confirmed the command exits successfully and the prefix currently contains
Breast/, Prostate_2/, and data/.
- No objects were created, changed, copied, or deleted.
Lessons Learned: Pitfalls
- The general histo workstream and SOP documents were not needed for this read-only storage lookup.
- A plain
aws s3 ls lists only the immediate children. Deeper inspection requires a child prefix or --recursive.
Lessons Learned: Improvements
- A short infrastructure SOP could document the configured Ceph AWS CLI profile and standard read-only listing commands, without storing credentials.
