Hi,
This is the very first time I tried doing a xfsrestore of a back up and I hit some serious trouble.
I had openSUSE 11.1 (kernel 2.6.27) on my Acer notebook. I did a xfsdump of /home to a WD My Passport external USB hard drive with XFS on it.
I installed openSUSE 11.4 (kernel 2.6.37), then tried to do xfsrestore from the WD USB drive. The dump file is 121 GB.
I tried two times on two different days, but each time the xfsrestore would stop writing at the exact same point, 49 GB and say success at the end.
I then copied the dump file to one hard drive on my desk top, and did a dump to another hard drive, to /tmp/mnt3. I get back identical messages:

I downloaded xfsdump-3.0.5.tar.gz, did a build, and tried to do a restore using the newly built xfsrestore:

Could some one please assist to enlighten me what is going on, why does the restoration fail? The xfsdump session looked OK.
Is there any way I can extract back my /home back up? This is my only back up copy. i have two other xfsdump dump files taken earlier, I have not tried those.
Is xfsdump and xfsrestore really robust for dump to regular file, or should I have done a tar instead?
Thank you.
