cephfs rm -rf on directory of 160TB /40M files

Hi all,

I want to remove a large directory containing +- 40M files /160TB of data in CephFS by running rm -rf on the directory via the ceph kernel client. After 7h , the rm command is still running. I checked the rados df output, and saw that only about 2TB and 2M files are gone. I know this output of rados df can be confusing because ceph should delete objects asyncroniously, but then I don't know why the rm command still hangs. Is there some way to speed this up? And is there a way to check how far the marked for deletion has progressed ?

Thank you very much!

Kenneth
