Hi Bruce- I'm running DELEG21 to unit-test delegations, and this message comes out at the end: Making sure b'DELEG21-1' is writable: operation OP_SETATTR should return NFS4_OK, instead got NFS4ERR_DELAY I guess there's no callback service running during the test's clean-up phase. Then if I run the test again immediately: [cel@morisot pynfs]$ sudo nfs4.0/testserver.py manet:/export/tmp --maketree --rundeps -v cel Initialization failed, no tests run. Perhaps you need to use the --secure option or configure server to allow connections from high ports Traceback (most recent call last): File "/home/cel/src/pynfs/nfs4.0/testserver.py", line 394, in <module> main() File "/home/cel/src/pynfs/nfs4.0/testserver.py", line 346, in main env.init() File "/home/cel/src/pynfs/nfs4.0/servertests/environment.py", line 150, in init c.clean_dir(self.opts.path) File "/home/cel/src/pynfs/nfs4.0/nfs4lib.py", line 579, in clean_dir check_result(res, "Making sure %s is writable" % repr(e.name)) File "/home/cel/src/pynfs/nfs4.0/nfs4lib.py", line 906, in check_result raise BadCompoundRes(resop, res.status, msg) nfs4lib.BadCompoundRes: Making sure b'DELEG21-1' is writable: operation OP_SETATTR should return NFS4_OK, instead got NFS4ERR_DELAY And I think this condition persists until the old lease expires and the server permits the client to delete that file. -- Chuck Lever
