OMERO demo cleanup

This OMERO command-line plugin allows you to compute the space per user, find the users with the biggest amount of data and free disk space on a server

To generate the list of users which data must be deleted to free 300GB on the system without running the deletion:

$ omero demo-cleanup --gigabytes 300

To ignore users who’s data whose data must not be deleted, you can Tag those users and specify the Tag or parent Tag Group by Name or ID. This is enabled by default using a Tag named “NO DELETE”. So it is preferable to Tag users on the server with a Tag named “NO DELETE” or create a Tag Group named “NO DELETE” containing Tags linked to users.

# Add a Tag to a User via CLI (not possible to see this in the clients) $ omero obj new ExperimenterAnnotationLink child=TagAnnotation:123 parent=Experimenter:52

# Choose a non-default Tag or Tag Group (by ID or Name) to ignore the tagged users $ omero demo-cleanup –gigabytes 300 –ignore-tag “Tag Name”

You can also specify individual users by ID or user name, e.g:

–ignore-users 123,user-1,ben,234

To generate the list of users which data must be deleted to free 300GB on the system and running the deletion (WARNING: data belonging to these users will be removed permanently):

$ omero demo-cleanup --gigabytes 300 --force
