I thought the tails would be used to save the file blocks with less than

Any tail can be packed if it doesn't match the block size.  In our case
the corruption evidenced itself as files with the first part being ok,
and the last part being all NULLs (0x0) up to the 'normal' file size.


I really should say *mostly* because yes, files that were entirely shorter than the blocksize were essentially gone (full of NULLs).

Our mail server makes the best use of reiserfs because of the huge number of files and the amount of files that end up packed.
