LinuxQuestions.org - NFS mp option ?

Hello,

SLES 11 Sp4.

I want nfs not to export empty mount points automatically, I want it to do exportfs after data filesystems are mounted (mounting data filesystems on my box is done manually).
So I found this option mp:

Code:

# man exports

      mountpoint=path



      mp    This option makes it possible to only export a directory if it has successfully been mounted.  If no path is given (e.g.  mountpoint  or  mp)  then

              the  export  point  must  also be a mount point.  If it isn't then the export point is not exported.  This allows you to be sure that the directory

              underneath a mountpoint will never be exported by accident if, for example, the filesystem failed to mount due to a disc error.

I tried to use it:

Quote:

# cat /etc/exports
/data1 host1(mp=/data1,rw,no_root_squash,sync,no_subtree_check)

After reboot /data1 is not mounted so I expect nfs not to export it, but nfs exports it anyway:

Code:

# exportfs

/data1

                host1.domain.com

"export -ua" works fine - unexports everything.
I tried using nfsv3 nfsv4 - same result.

Any ideas where is the problem ?

Thanks,
Vilius M.
