    Pour l'avoir fait (avec mdadm) je dirais tout simplement que c'est faux.

    Par contre attention, c'est violent et ça prend du temps !

    Et surtout il ne faut pas oublier :

    -b, --bitmap=
 Specify a file to store a write-intent bitmap in. The file should not exist unless --force is also given. The same file should be provided when assembling the array. If the word internal is given, then the bitmap is stored with the metadata on the array, and so is replicated on all devices. If the word none is given with --grow mode, then any bitmap that is present is removed.
 To help catch typing errors, the filename must contain at least one slash ('/') if it is a real file (not 'internal' or 'none').
 Note: external bitmaps are only known to work on ext2 and ext3. Storing bitmap files on other filesystems may result in serious problems. 
--backup-file=
 This is needed when --grow is used to increase the number of raid-devices in a RAID5 or RAID6 if there are no spare devices available, or to shrink, change RAID level or layout. See the GROW MODE section below on RAID-DEVICES CHANGES. The file must be stored on a separate device, not on the RAID array being reshaped.
