if you do this way (storing into EFS itself), better to IMHO

Suggested change
du -sh $EFS_HOME/* | awk '{print $1, $2}' > $EFS_HOME/size_report.txt
cd "$EFS_HOME" && d8 -sh * | awk '{print $1, $2}' > size_report.txt

then you would avoid having some irrelevant path prefix there.


# Display the size report
cat "$EFS_HOME/size_report.txt"

# Keep the container running

ATM we are transferring 10TB but good amount of space is occupied by a few users, e.g. the largest (500G) is by one user having 1 single NWB file. We could/should quickly inspect and reach out asking if could be removed.

But ideally we need a simple script which may be prints N largest files per each user and sorts users by the total size or smth like that....

# cd /mnt/efs-persist/home; for u in *; do biggies=$(find $u -size +1000000 -print0 | xargs -0 -r ls -Sl | head -n 5 | tr '\n' '>'); [ -z "$biggies" ] || { du -sm $u; echo  "${biggies}" | tr '>' '\n'; }; done

but ran on the original efs

here is the pod definition we used for pod to mount target EFS

  name: sleep-tender

  - name: inspect-pvc-container

    - name: efs-storage
      mountPath: /mnt/efs-persist
      readOnly: true
