I am replacing an old NFS server that is now running RHEL 3u7 with a new one on which I installed RHEL5.1. The new one is up to date - kernel is 2.2.18-53.1.14.el5, x86_64. The old server, and others, have run for a long time without showing the problems described briefly below.
The new system, when accessed by a certain set of NFS clients, generates scary looking I/O errors in the output stream for commands like ls -l . The errors only reflect bad handling of NFSACL calls ( V3 GETACL calls). There may be other issues but one obvious one is that the server is responding to the NFSACL calls with, to quote wireshark output:- " Mesage Type: Reply (1) [Program: NFSACL (100227)] [Program Version: 3] [Procedure: GETACL (1)] Reply State: Accepted (0) . . Accept State: Remote can't support version # (2) Program Version (Minimum) : 3 Program Version (Maximum) : 0 " Note the crazy max and min values at the end - assuming wireshark is interpreting them correctly. This may not be the NFSACL problem but the problem is definitely related to NFSACL calls. A final bizarre comment is that some other machines running Scientific Linux 5.1 do not show these problems as NFS servers, and SL 5.1 is just a dustribution based on RHEL 5.1. Even have the same kernel and nfs-utils. Any ideas please ?
