There must be something wrong with that device,
it must show in lsblk output (but it is not there).

Seems like it is partially removed (empty table) - can you add
output of

dmsetup table sata_p1_2TBa
dmsetup info -c sata_p1_2TBa
blockdev --getsz /dev/mapper/sata_p1_2TBa ?

(btw another mapping will not show in lsof, but it should
be visible in lsblk. If it is reproducible I would like to at least
fix lsblk so we have some reliable tool to debug it...)
