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!
