Hi everyone,
I am new to the list. I have a question about automount on
a root-level symlink on the local node.
At / I have the following:
export
sio_files -> export/etms7/sio_files
When I attempt the following:
ls -alp /nfs/mdw(my local machine name)/sio_files
I receive an error stating that the directory does not exist.
Subsequent attempts show the following:
/nfs/mdw/sio_files -> /sio_files
I see from the log files that the automounter attempted a
mount --bind which failed but then successfully created
a symbolic link.
The follwing command:
/nfs/mdw/export
always succeeds without error and an actual mount is performed
instead of a symbolic link.
Shouldn't a success status be returned whether a symbolic link is
created or an actual mount --bind is completed? Will this work
with symbolic links?
I am enclosing a snippet of my /var/log/messages.
Thank you for your assistance.
