Subject: nfs problem: nfs could be mounted and viewed but errors on file opening
Date: Fri, 10 Sep 2004 13:50:37 +0800 [thread overview]
Message-ID: <1094795240.3169.17.camel@roach.aldevinco.com> (raw)
i'm having problems opening my nfs mounted files on the client machine.
Mounting the nfs share on the client goes ok. the user and group
permissions are ok. i could even ls -l and cd into the mounted directory
and subdirectories but when i open a file (cat somefile.txt) i get a
segmentation fault. after that, umounting the nfs share seems to hang.
i noticed this problem when i upgraded the kernel on the client machine
from 2.4 to 2.6. (is there any relation?)
server config: client config:
nfs-utils version 1.0.1 nfs-utils version 1.0.1
kernel ver. 2.4.18-14 kernel ver. 2.6.8
redhat 8.0 distro fedora core 1.0
/etc/exports = "/data/revr 192.168.168.1(ro,sync)"
rpcinfo -p localhost on the server:

the nfs-utils on the client was originally 1.0.6. i tried installing
nfs-utils 1.0.1 but still the same error message. i hope this
information is enough to solve my nfs problem. tia
