To summarize... The link https://access.redhat.com/knowledge/solutions/306063 lists two issues 1. Files on NFS share are not getting displayed while executing ls In the example there are 347 files on server file system and 3 on client.
In my case, I found one missing directory (not on client, but on server). All files in troublesome directories and 2 of 3 subdirectories listed 3 times each. They are listed properly, one time each, on NFS server file system. 2. On RHEL 6 NFS client, multiple . & .. entries getting listed when looking at them using ls? These direcories not there on NFS server: Well, my NFS (SL6.1) client saw multiple entries, however, the entries actually exist on server file system. So different. I can add from my notes, (I can't reboot to broken kernel today due to other's work), a) client side dmesg messages such as: NFS: directory COMPILE_MATLAB/tsa contains a readdir loop.Please contact your server vendor. The file: ..�%�������������������� has duplicate cookie 1816244270 NFS: directory matlabtools/pltwave contains a readdir loop.Please contact your server vendor. The file: getwordsAll.m has duplicate cookie 653075819 NFS: directory jr02_19/1 contains a readdir loop.Please contact your server vendor. The file: dmx.T007 has duplicate cookie 1805553535 b) boot of server (SL5.9) with broken kernel 2.6.18-348.1 showed RPC.idmap or idmapd (don't recall) with RED ERROR message. I don't remember seeing this when rebooting with older kernel that worked 2.6.18-308.24.1.el5.
