Ok, problem solved now, the last poster was spot on, for some reason that I cannot figure out, there was a regular file /dev/sdb1. After removing it (with the drive disconnected), everything works. The drive is a Seagate Backup Plus portable drive I'm running cryptsetup version 1.4.3 (the version in Slackware64 14.0, running kernel 3.8.8) # dd if=/dev/zero of=/dev/sdb bs=1GB dd: writing '/dev/sdb': No space left on device 1001+0 records in 1000+0 records out 1000204885504 bytes (1.0 TB) copied, 12064.5 s, 82.9 MB/s so it is really 1.0 TB there (not a fake one) #smartctl -i /dev/sdb: Unknown USB bridge [0x0bc2:0xa013 (0x100)] Now, status reports the full drive and no loopback: # cryptsetup -v status pjhomecrypt /dev/mapper/pjhomecrypt is active. type: LUKS1 cipher: aes-cbc-essiv:sha256 keysize: 256 bits device: /dev/sdb1 offset: 4096 sectors size: 1953521008 sectors mode: read/write Command successful. The filesystem was created successfully with ~ 1 TB. Problem solved.
