Thinking that it might be a xfsdump version incompatibility, I dug out the 
openSUSE 11.1 installation DVD, got the xfsdump-2.2.48-1.59 rpm and extracted 
the xfsdump and xfsrestore from it.  I then attempted a restore using it, but I 
still have only 49 GB of 121 GB extracted:

Is this a case of xfsdump bug that causes null data to be written, or 
xfsrestore bug that is unable to read back the data?


Thanks!
