Hi all, maybe this was already explained, but I could not find something specific. Given a parity array (RAID-456) with bitmap, when add HDD accidentally disconnects, it can be re-added. That is, only the bitmapped changes are synchronized. Now, sometimes this is not possible, that is the disk *must* be added, with full synchronization. Questions: 1) What's the criteria used by "mdadm" to decide if an HDD can be re-added or it must be added? 2) Knowing that the HDD can be re-added, can be this forced? (I did *not* try --force).
