Hi,

I run exportfs command:
[root@rncpetdev1 user]$ exportfs -vr
exporting 10.118.213.0/24:/HDD2/scratch/ruchgupta_nwt/4.4_latest
exporting 10.118.213.0/24:/usr/java/jdk1.5.0_09
exporting 10.118.213.0/24:/HDD2/5.2.latest

exporting rncpet70:/HDD2 to kernel

i run it again

[root@rncpetdev1 user]$ exportfs -vr
exporting 10.118.213.0/24:/HDD2/scratch/ruchgupta_nwt/4.4_latest
exporting 10.118.213.0/24:/usr/java/jdk1.5.0_09

exporting 10.118.213.0/24:/HDD2
exporting 10.118.213.0/24:/home
exporting rncpet70:/HDD2 to kernel
rncpet70:/HDD2: Invalid argument
exporting suntester:/HDD2 to kernel
suntester:/HDD2: Invalid argument

why it is giving different outputs?

after running it second time my problems og nfs get solved.

Please add your distro & version to your profile in order to get the correct help.
Also post the nfs version.
