Yep, in 1k units, so:

19046932480*1024
19504058859520

and:

superblock read failed, offset 19504058859520, size 2048, ag 64, rval 0

so it's trying to read a 2k (?) superblock right in the last 1k of the
device?  Hrm.  (Dave, Barry - isn't that 2048 the sector size, not block
size?)

Also from your sb 0 printout:

blocksize = 4096
dblocks = 11904332800

is 48760147148800, exactly 2.5x bigger than your device is. Weird.
