-W, --write-mostly
subsequent devices lists in a --build, --create, or --add command will be flagged as ’write-mostly’. This is valid
for RAID1 only and means that the ’md’ driver will avoid reading from these devices if at all possible. This can be
useful if mirroring over a slow link.
Je n'ai jamais essayé mais ça a l'air de correspondre à ton besoin.
