Hi,
I share directories on a Scientific linux cluster by using nfs
tool.
SLC6 kernel 2.6.32-279.22.1.el6.x86_64
nfs-utils-1.2.3-26.el6.x86_64
After a server-client shutdown, a disagreeable event occurred.
By making ls list on a nfs client shared directory, duplicated entries for
some files are shown.
Other files and sub-directories are non visible. The problem is not
present on the nfs server.
The directory don't contain an enormous number of files:
On the server:
#ls |wc -l
330
#du -s
8855740
On the client:
#ls |wc -l
ls: reading directory .: Too many levels of symbolic links
120
n.b. there are only two symbolic links and they are not changed after the
shutdown; however, the problem is not cleared if I remove them.
#du -s
not responding
#dmesg
some entries:
...
NFS: directory images/dp contains a readdir loop.Please contact your
server vendor. The file: .. has duplicate cookie 683570819

I've tried to boot the system with the older kernel-2.6.32-279.el6.x86_64,
and with the new kernel 2.6.32-358.2.1.el6.x86_64 but the bug is not
cleared. Any ideas?
Many thanks in advance
Antonietta
