Invalid snapshot is meant to be shown by I (for invalid) in the 5th position.

              The lv_attr bits are:

              1  Volume  type:  (m)irrored,  (M)irrored  without initial sync,
                 (o)rigin, (O)rigin with merging snapshot, (s)napshot, merging
                 (S)napshot,   (p)vmove,  (v)irtual,  mirror  (i)mage,  mirror
                 (I)mage out-of-sync, under (c)onversion

              5  State:  (a)ctive,  (s)uspended,  (I)nvalid  snapshot, invalid
                 (S)uspended snapshot, mapped (d)evice present without tables,
                 mapped device present with (i)nactive table

If some particular case is giving the wrong output, please show us exactly which
case that is, and how the output looks, together with 'dmsetup info -c',
'dmsetup table' and 'dmsetup status'.
