Hi Pierre,
Here goes the fstab file in the CLIENT.
Indeed, it presents the hard option:
[root at lflip23 ~]# more /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
ce02.lip.pt:/usr/local/sge/utils_scripts /usr/local/sge/utils_scripts
nfs4 rw,hard,intr,proto=udp,port=2049,auto 0 0
ce02.lip.pt:/exp-soft /exp-soft nfs4
rw,hard,intr,proto=udp,port=2049,auto 0 0
Here goes the server fstab and server config files (I didn't know which
one you were referring to so I posted all):
[root at ce02 ~]# more /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
/usr/local/sge/utils_scripts
/export/usr/local/sge/utils_scripts ext3 bind,rw 0 0
/exp-soft /export/exp-soft ext3 bind,rw 0 0
*****************************************
root at ce02 ~]# more /etc/exports
/export *.lip.pt(rw,fsid=0,insecure,no_subtree_check,sync,no_root_squash)
/export/usr/local/sge/utils_scripts

/export/exp-soft
*.lip.pt(rw,nohide,insecure,no_subtree_check,sync,no_root_squash)

# GSSAPI Mechanism Definitions

# This configuration file determines which GSS-API mechanisms

# NOTE:
# The initiaiization function "mechglue_internal_krb5_init"
# is used for the MIT krb5 gssapi mechanism. This special
# function name indicates that an internal function should
# be used to determine the entry points for the MIT gssapi
# mechanism funtions.

# library initialization function
# ================================ ==========================
# The MIT K5 gssapi library, use special function for initialization.
/usr/lib/libgssapi_krb5.so mechglue_internal_krb5_init
#
# The SPKM3 gssapi library function. Use the function spkm3_gss_initialize.
# /usr/local/gss_mechs/spkm/spkm3/libgssapi_spkm3.so spkm3_gss_initialize
Thanks
