(Automatic) repair may not be allowed during the initial sync of an upconverted linear LV, because the data on the failing, primary leg hasn't been completely synchronized to the N-1 other legs of the raid1 LV (replacing failed legs during repair involves discontinuing access to any replaced legs data, thus preventing data recovery on the primary leg e.g. via dd_rescue). Even though repair would not cause data loss when adding legs to a fully synced raid1 LV, we don't have information yet defining this state yet (e.g. a raid1 LV flag telling the fully synchronized status before any legs were added), hence can't automatically decide to allow to repair. If nonetheless a repair on a non-synced raid1 LVs is intended, the "--force" option has to be provided. Resolves: rhbz1311765
