Hi, for what it's worth, the sample code given works with nfs-ganesha server, so I'm not sure what's not working here. Here's the server traces: TATTACH: tag=1 fid=0 afid=-1 uname='nobody' aname='/export' n_uname=-1 RATTACH: tag=1 fid=0 qid=(type=128,version=0,path=1) TGETATTR: tag=1 fid=0 request_mask=0x7ff RGETATTR: tag=1 valid=0x7ff qid=(type=128,version=0,path=1) mode=040755 uid=0 gid=0 nlink=3 rdev=192 size=4096 blksize=4096 blocks=8 atime=(1428909387,0) mtime=(1428909389,0) ctime=(1428909389,0) btime=(0,0) gen=0, data_version=0 TATTACH: tag=1 fid=1 afid=-1 uname='' aname='/export' n_uname=0 RATTACH: tag=1 fid=1 qid=(type=128,version=0,path=1) TGETATTR: tag=1 fid=1 request_mask=0x3fff RGETATTR: tag=1 valid=0x7ff qid=(type=128,version=0,path=1) mode=040755 uid=0 gid=0 nlink=3 rdev=192 size=4096 blksize=4096 blocks=8 atime=(1428909387,0) mtime=(1428909389,0) ctime=(1428909389,0) btime=(0,0) gen=0, data_version=0 TWALK: tag=1 fid=1 newfid=2 nwname=1 (component 1/1 :test.txt) RERROR(_9P_TWALK) tag=1 err=(2|No such file or directory) TWALK: tag=1 fid=1 newfid=2 nwname=0 RWALK: tag=1 fid=1 newfid=2 nwqid=0 fileid=1 pentry=0x8278c0 refcount=4 TLCREATE: tag=1 fid=2 name=test.txt flags=0100102 mode=0100644 gid=0 RLCREATE: tag=1 fid=2 name=test.txt qid=(type=0,version=0,path=144115205255725065) iounit=0 pentry=0x7fffc0000d00 TWALK: tag=1 fid=1 newfid=3 nwname=1 (component 1/1 :test.txt) RWALK: tag=1 fid=1 newfid=3 nwqid=1 fileid=144115205255725065 pentry=0x7fffc0000d00 refcount=3 TGETATTR: tag=1 fid=3 request_mask=0x17ff RGETATTR: tag=1 valid=0x7ff qid=(type=0,version=0,path=144115205255725065) mode=0100644 uid=0 gid=0 nlink=1 rdev=192 size=0 blksize=4096 blocks=0 atime=(1428909674,0) mtime=(1428909674,0) ctime=(1428909674,0) btime=(0,0) gen=0, data_version=0 TWRITE: tag=1 fid=2 offset=0 count=6 RWRITE: tag=1 fid=2 offset=0 input count=6 output count=6 TUNLINKAT: tag=1 dfid=1 name=test.txt TUNLINKAT: tag=1 dfid=1 name=test.txt TGETATTR: tag=1 fid=3 request_mask=0x3fff RGETATTR: tag=1 valid=0x7ff qid=(type=0,version=0,path=144115205255725065) mode=0100644 uid=0 gid=0 nlink=0 rdev=192 size=6 blksize=4096 blocks=0 atime=(1428909674,0) mtime=(1428909674,0) ctime=(1428909674,0) btime=(0,0) gen=0, data_version=0 TCLUNK: tag=1 fid=2 RCLUNK: tag=1 fid=2 TCLUNK: tag=1 fid=3 RCLUNK: tag=1 fid=3 (if you're not familiar with 9P, ATTACH = mount, WALK = create a new 'fid' either clone of current file (nwname = 0) or lookup, CLUNK ~= close. Rest is obvious enough) There's no lookup between the unlink and the getattr, so what I think is missing is that both qemu and diod do not understand that fids 2 and 3 refer to the same open file ? It's a bit of a weird behavior that the client will open a new fid through lookup walk for a first stat, but I'm mounting with cache=none here so you should be having the same. -- Dominique -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
