The Tru64 NFS servers pretend that a directory is not a directory.
However when we issue the "file" or the "ls -l" command the system clearly indicates that it is a real directory.
The Tru64 systems have only AdvFS file systems.
This is the client (perseus)
uname -a
Linux perseus 2.6.22.5-31-default #1 SMP 2007/09/21 22:29:00 UTC x86_64
x86_64 x86_64 GNU/Linux
cd /mnt/hbsitlab/users
cd attilaf
bash: cd: attilaf: Not a directory
file attilaf
attilaf: directory
* We have the problem both with Tru64 V4.0F and V5.1-b servers
* It works correctly with an old AlphaServer 1000A server with (an even older) Linux Red Hat V7.2 and the same new SuSE V10.3 64 bit NFS client
* Other NFS clients do not have this problem!
* The /etc/fstab and /etc/exports files are OK
* File protection and UID/GUI mapping is OK
* The network setup should be OK
Can you please help us?
* Would SuSE be incompatible with Tru64?
* Would Tru64 not be compatible with SuSE?
# Tru64 NFS server (hbsitlab)
cat /etc/exports
/users -anon=-2 -root=hbsitprod perseus
# Linux Red Hat V7.2 NFS server on an AlphaServer (hbsitvxt)
cat /etc/exports
/home perseus(rw,sync,no_root_squash)
# SuSE V10.1 NFS client (perseus)
cat /etc/fstab
hbsitlab:/users /mnt/hbsitlab/users nfs defaults 0 0
hbsitvxt:/home /mnt/hbsitvxt/home nfs defaults 0 0
Solved! Go to Solution.

Re: SuSE NFS client with Tru64 NFS server - No such Directory
I'd probably infer something from that.

Re: SuSE NFS client with Tru64 NFS server - No such Directory
I believe that there might be an interoperability problem between the SuSE NFS client and the Tru64 NFS servers.

Well the servers are running completely different operating systems for a start ! The fact that both machines are AlphaServers is irrelevant.
Do you get any useful errors in the log files... /var/adm/syslog.dated/current/daemon.log IIRC.
Cheers,
Rob

Re: SuSE NFS client with Tru64 NFS server - No such Directory
The disk was mounted by NFS client (without errors) -- only the directories are not recognized...

SolutionThe problem is that the Tru64 NFS server READDIRPLUS reply. Also note that this problem is specific to the V3 server.
If there is a mechanism avaible for you in SUSE Linux to disable using READIRPLUS on the client side, you can use that as well.
The problem can be seen with linux kernel
versions above certain number (2.6.11 probably i,m not sure of the exact version number) but caused by a Tru64 NFS server problem.
The reason why it works with the older Linux versions is that they don't pay attention to the wrong field that the Tru64 NFS server sends back.

and it works :-) Thanks to you all!
