This was long pending task, and now is complete. But the uid/gid mapping has a upper limit of 32 mappings per translator instance. Also it provides the 'root-squashing' option like NFS. Hope few people like it. Code committed to glusterfs--mainline--3.0--patch-323 I have done testing of few straight forward cases. There may be glitches in some corner cases. Let me know how it works for you. Regards, Amar 2007/7/3 Anand Avati <avati@xxxxxxxxxxxxx> > Bruce, > Yes, your idea makes sense. Basically the fixed-id translator came in as a > hack a while back.
