Subject: [PATCH 39/40] staging/lustre/utils: HSM Posix CopyTool
From: JC Lafoucriere <jacques-charles.lafoucriere@....fr>
POSIX HSM CopyTool utils named lhsmtool_posix.
This user space command is the 'glue" between Lustre-HSM
and a POSIX filesytem used as a backend.
The main functionalities implemented are:
daemon mode:
- archive: read in lustre write with POSIX backend
- restore: read in POSIX backend write to Lustre
- remove: remove an entry from backend
cmd line mode:
- import: create in lustre a released file from a backend file
- rebind: change the FID associated to a file in the backend
- maxseq: get the larger sequence of FID found in the backend
The 2 last options are used for disaster recovery mode
This tools is also used for all the non regression tests made in
sanity-hsm.sh
