I just applied the latest updates to my CentOS 5 cluster;

kernel is now 2.6.18-53.1.4.el5

Sun NFS clients now show error messages when long listing files;

# ls -l dantest NFS getacl failed for server centos-cluster: error 9 (RPC: Program/version mismatch) NFS getacl failed for server centos-cluster: error 9 (RPC: Program/version mismatch) NFS getacl failed for server centos-cluster: error 9 (RPC: Program/version mismatch) NFS getacl failed for server centos-cluster: error 9 (RPC: Program/version mismatch) NFS getacl failed for server centos-cluster: error 9 (RPC: Program/version mismatch) total 32 drwxrwxrwx 1 dan users 0 Aug 22 10:36 dantest

It works, there just seems to be a problem with the GETACL NFS call on the updated kernel. Backing filesystems are GFS. Booting back to the old kernel (2.6.18-8.1.8.el5) and the problem is gone. Anyone else seen this problem?
