[PVFS-users] unable to mount client

Tue Jul 6 09:38:05 EDT 2004

Sorry, I just noticed something today.
When I configured pvfs-kernel-1.6.2-linux-2.4, I copied the pvfs.o using :
cp /lib/modules/2.4.18-27.7.x/kernel/fs/
But when i insmod pvfs, it tells me that :
Using /lib/modules/2.4.18-27.7.x/fs/pvfs.o

Does that means it is using the old one instead of the other one I'm 
supposed to use?

Thank you.
