So is 'exportfs -r' *supposed* to stale all NFS handles?  If so, is this
adequately documented?  adTHANKSvance

Package: kernel
Version: N/A; reported 2002-05-29
Severity: grave
Justification: causes non-serious data loss

While diagnosing an autofs problem with a particular client, I wanted to reload
changes to the /etc/exports file into the kernel nfs server. I ran:

/etc/init.d/nfs-kernel-server reload

which basically runs the command:

exportfs -r

The man page for this command does not indicate this is a destructive action
and I know I have run this same command on previous versions of the kernel with
no problems.

The result this time was that every client with automounted home directories
immediately got stale file handles which caused them to lose access to their
running apps. We had to go to each client to manually restart autofs on each
client to restore the nfs file handles. Unfortunately, many people lost the
files they were working on.
