Impact of the bug
T2_CH_CERN site

Describe the bug
As a consequence of the bug: #11893 we have accumulated almost 1 PB of data in the /store/unmerged area at T2_CH_CERN . The combination of the previously prolonged fix of the Gfal recursive errors leads to a lot of empty directories being accumulating as well. This two govern the necessity of initial manual intervention for cleaning those either trough

• a standalone run of the MSUnmerged at T2_CH_CERN
• or by manually implementing the logic of filtering out the protected LFNs and doing the deletions directly on an /eos mount point.

For the later we have to either ask the VOC for delete permissions at /eos/cms/store/unmerged area or provide a list of deletable objects and let him or DM Team to do the deletions

How to reproduce it
N/A

Expected behavior
Follow up on the manual intervention and delete all unneeded objects

Additional context and error message
