For unlink() system call to delete a file, does the Ceph kernel client go through ceph_unlink()? If so, it seems from the code tht client only communicate with MDS for metadata operation, client seems not contact with OSD to delete the object. So, is that MDS takeing the responsibility of deleting file data? And, we find the definition of CEPH_OSD_OP_DELETE (include\linux\ceph\rados.h), however, it seems it never actually used in the kernel client code, is it left for future? Thanks for your time. Regards, Li Wang > Lets keep this discussion on the mailing list so everyone can benefit from the discussion, cc'ing it here. As for your questions, the MDS is responsible for removing the objects. The kernel fs client code has probably no need for that operation.
