I am unable to complete a mount request. It fails for one of two causes. 1. Client's request fails with ESTALE This happens when the server tries to authenticate the client's UNIX credentials. The first svc_athenticate(1) succeeds, and the second reports: svc: svc_authenticate (1) RPC: Want update, refage=120, age=0 svc: calling dispatcher nfsd_dispatch: vers 3 proc 19 nfsd: FSINFO(3) 12: 00000001 0000fd00 00380001 00000000 00000000 00000000 nfsd: fh_verify(12: 00000001 0000fd00 00380001 00000000 00000000 00000000) RPC: Want update, refage=120, age=0 found domain -test-client- found fsidtype 0 found fsid length 8 Path seems to be <> revisit queued The only place I can find -test-client- in in exportfs.c. I am at a loss as to how it ends up here. 2. Client's request fails with EACCESS I believe this is actually a RPC_AUTH_BADCRED issue on the server that is returned to the client, which converts it to EACCESS in client.c. I am still trying to diagnose both cases and I would entertain any suggestions. ;-) Thanks, Scott -- Scott Atchley Myricom Inc. http://www.myri.com
