exported filesystems on a NIM server

I have a filesystem that was exported sometime in the past, probably by NIM processes, but cannot be unexported now. How can I get rid of this? Any ideas? I tried rebooting and it survived it.

hostname:/:$ exportfs -v                                
/usr/lpp/bos.sysmgt/nim/methods -ro,root=remotehost,access=remotehost

hostname:/:$ ls -ld /usr/lpp/bos.sysmgt/nim/methods
drwxr-xr-x    2 root     system         8192 Nov 30 15:15 /usr/lpp/bos.sysmgt/nim/methods

hostname:/:$ exportfs -u /usr/lpp/bos.sysmgt/nim/methods
exportfs: /usr/lpp/bos.sysmgt/nim/methods: A file or directory in the path name does not exist.

hostname:/:$ exportfs -Fu /usr/lpp/bos.sysmgt/nim/methods
exportfs: /usr/lpp/bos.sysmgt/nim/methods: A file or directory in the path name does not exist.

hostname:/:$ exportfs -ua                               
exportfs: /usr/lpp/bos.sysmgt/nim/methods: A file or directory in the path name does not exist.

hostname:/:$

Did you try to remove it from /etc/exports and reboot once more ?

That exported filesystem that I showed is not in the /etc/exports file. It is very strange that it will not go away.

The problem is that the filesystem was in the /etc/xtab (whatever that file does). Here's how I got rid of that mysteriously exported filesystem:

hostname:/:$ exportfs -v
/usr/lpp/bos.sysmgt/nim/methods -ro,root=remotehost,access=remotehost

hostname:/:$ cat /etc/xtab
/usr/lpp/bos.sysmgt/nim/methods -ro,root=remotehost,access=remotehost

hostname:/:$ stopsrc -g nfs
0513-044 The biod Subsystem was requested to stop.
0513-044 The nfsd Subsystem was requested to stop.
0513-044 The rpc.mountd Subsystem was requested to stop.
0513-044 The rpc.lockd Subsystem was requested to stop.
0513-044 The rpc.statd Subsystem was requested to stop.

hostname:/:$ rm /etc/xtab

hostname:/:$ startsrc -g nfs

0513-059 The rpc.statd Subsystem has been started. Subsystem PID is 3080274.

hostname:/:$ exportfs -v
exportfs: 1831-182 nothing exported
hostname:/:$

Finally.... shesh.
