Description

The posix copytool imports files that are designated by their path in the backend, despite being itself the only one to know this path.

We propose a slight improvement to make the posix CT also accept a FID as import source parameter (from which the path can be rebuilt). This would allow easy "undeletion" of archived files:

lhsmtool_posix --import <fid> /mnt/lustre/undelete ...
