I *KNOW* what the command does. I've read the man page and the book.

HOWEVER, the way this used to work (and apparently not anymore) was you were free to unexport/unshare a dir/vol globally (IE: exportfs -u -a /usr/local) but it would *NOT* affect *EXISTING* mounts. Just newly requested ones.

I'll go quietly now...

SunOS/BSD Compatibility Package Commands exportfs(1B)

NAME exportfs - translates exportfs options to share/unshare com- mands

SYNOPSIS /usr/sbin/exportfs [ -aiuv ] [ -o options ] [ pathname ]

DESCRIPTION exportfs translates SunOS 4.x exportfs options to the corresponding share/unshare options and invokes share/unshare with the translated options.

 With no options or  arguments,  exportfs  invokes  share  to
 print out the list of all currently shared NFS filesystems.

 exportfs  is  the  BSD/Compatibility  Package   command   of
 share(1M) and unshare(1M). Use  share(1M)/ unshare(1M) when-
 ever possible.

OPTIONS -a Invokes shareall(1M), or if -u is specified, invokes unshareall(1M).

 -i    Ignore options in /etc/dfs/dfstab.

 -u    Invokes unshare(1M) on pathname.

 -v    Verbose.

 -o options
       Specify a comma-separated  list  of  optional  charac-
       teristics for the filesystems being exported. exportfs
       translates options to share-equivalent  options.  (see
       share(1M) for information about individual options).

Perhaps I'm rusty with my NFS knowledge....

I made a change to my /usr/local export. (-root on a build host) I did an "exportfs -u -a" and to my horror all of the *existing* /usr/local mounts went stale.

I do not remember this happening with Auspex's (in a previous life) and SunOS 4.1.2. Perhaps I need to go back to the blue NFS/NIS O'Reilly book....

Is this a Solaris 2.8 ism, or am I missing something obvious in my re-entry to the world of NFS...

Here is my vfstab entry:

well:/vol/sysvol0/local

•   /usr/local      nfs     no      yes     bg,soft,intr
  
  

TIA
