Bug: deleted images not freeing space

[wmoore]

Seems that Scott has deleted a lot of images on gretzky (Big Images)? that have not freed up space on disk.

Free disk space (using $ df) is approximately the same as that reported in webadmin, so this seems to be reporting correctly. Must also be including the deleted imgaes/pixels.

In Scott's 'JRS-read-only' group, under Orphaned images, there are a bunch of images with failing thumbnails. E.g.

  id   | permissions | methodology | physicalsizex | physicalsizey | physicalsizez | sha1 | sizec | sizet | sizex | sizey | sizez | timeincrement | version | waveincrement | wavestart | creation_id | external_id | group_id | owner_id | update_id | dimensionorder | image | pixelstype | relatedto | image_index |     path      | name  | repo |     params

This references a file on disk:

omero@gretzky:~$ ls -al /OMERO/Files/Dir-014/14779
-rw-r--r-- 1 omero omero 421455123 2011-10-17 11:58 /OMERO/Files/Dir-014/14779

This file is not removed when the image is deleted, even though the row is removed from pixels table.
