Re: odd inconsistency with nfs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



James H, James P, and Leon, thanks for your replies. Here's what I have 
in answer to your questions/suggestions:

We do not use tcp_wrappers or iptables. The functional server is the 
redhat 7.3 box, the semi-functional server is the centos 6.4 box. On the 
centos 6.4 box, one share works as expected and the other does not. The 
use of symlinks does not appear to matter as both shares use them and 
one works while the other does not.

For now, I am ignoring automounting and mounting everything manually so 
that I can explicitly declare the options I want each time.

A summary of the testing (detailed output below):

The two shares on the centos 6.4 server have been mounted on a centos 
6.4 client, a solaris 5.8 client, and a solaris 5.6 client. The centos 
6.4 client and solaris 5.8 client are able to successfully execute an 
'ls *' on both the mounted shares, the solaris 5.6 client is not able to 
successfully execute 'ls *' on one share but is able to do so on the 
other. The two shares are each sub-directories of two partitions mounted 
on the centos 6.4 server. As far as I can tell, the two partitions are 
set up the same way, only difference is the naming. Other than the 
/etc/exports file, no other nfs-related configuration has been done on 
the server so the config files are the vanilla versions created when the 
packages are installed.

I would like to be able to have the solaris 5.6 client be able to mount 
a given share and operate in the same manner as the rest of the clients, 
execute 'ls *' and whatever else. My coworker who is the one that 
brought this to my attention suggested that the issue might be with nfs 
versions, since the old server used nfs3 and the new one can use nfs4, 
but I've explicitly forced nfs3 on all the mounts and it doesn't appear 
to make a difference.

Thanks!
Miranda
