I've looked into the export.c code in the kernel client. It looks like the primary issue may be incompleteness, as for non-connected filehandles, the dentry lookup does not query the mds but instead returns stalefh if it's not in the cache. For connected filehandles, ceph_mdsc_* methods are called to lookup dentries.
I understand there's not a lot of interest in re-exporting a ceph fs over NFS. But if I were to go ahead and investigate the APIs and find how to make that query for non-connected filehandles, would I be running into any obvious roadblocks? (I'd consider a "roadblock" something like: "there's no interface to make that lookup" or "you'll get non-deterministic results") thanks, Brian -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
