As you mention it: I've got a report from a customer that a certain
access pattern does not work anymore: GPFS has the ability to show the
.snapshots directory (the one where all the @GMT- subdirs show up) in
all directories, with @GMT- subdirectories being relative to the
current dir.

For clients that do not understand the @GMT- logic or the timewarp
token, essentially all non-windows clients, we need to be able to
access previous versions through the subdir/.snapshots/@GMT-../subdir
path. I think in the shadow_copy2 module we need to also preserve the
non-stripped name and try with that also. Any other ideas?

Thanks, Volker
