Does just adding a .db suffix make the name safe? If yes, xattr is not needed; if no, it's not enough. Reading src/rados_export.cc and src/rados_sync.cc, I see nothing like that. What if I have objects "foo" and "foo.db" in a pool? Note to self: the only thing avoiding collisions for e.g. "foo/" and "foo$" is the hash. > A related problem is how to store placement key strings for objects with > modified placement; I can't remember if we already did something for that > yet or not (maybe specially-named xattr?). Commit 717621f66eb7da54c0000ff52985235dc6a17843, combined with nothing else touching src/rados_export.cc after it, makes me think we don't preserve the locator. -- 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
