[Linux-HA] heartbeat with "exportfs -u"

[Kian_Chang_Low at veritasdgc.com]

Hi,

I'm trying to write a script (NFSserver) for exporting (or unexporting) a 
filesystem. With this script in place in the resource.d directory, my 
entry in the haresources will be something like this ...

nodeP  IPaddr::192.168.1.100  LVM::vg000 
Filesystem::/dev/vg000/lvol1::/data::ext3  NFSserver

With the nfsd running, the NFSserver script basically use "exportfs  ..." 
to export the filesystem and "exportfs -u ..." to unexport the filesystem. 
However, I notice that "exportfs -u" will always cause the client to 
encounter a "Stale NFS file handle" problem, but without "exportfs -u", I 
can not umount the filesystem!

I'm not too concern with NFS locking at the moment, or the various files 
in the /var/lib/nfs directories. These will come later. And if the script 
works, it will be a step closer to a rudimentary Active/Active NFS server.

I was wonder whether has anyone attempted such a script or any suggestion 
to get around this problem?

Thanks,
Kian Chang.
