I have an xfs filesystem on an lvm volume on an i386 ide disk. xfsdump
seems to happily work:

date=`date +%y-%m-%d`
xfsdump -l 0 -p 30 -L home.full.$date -M home.full.$date - /home

I wanted to save the dumps to cd so I pipe the above dump into split:

| split --bytes=700m - home.0.$date.

then create iso9660 images and burn them.

When I restore, I copy the files then cat them into xfsrestore -
<dest>

Should this work? At the moment cat home.0.02-10-01.a* | xfsrestore -p
30 -J -v trace - /mnt/temp/ seems happy until it suddenly returns 135
complaining of "bus error".

I can't find any mention of bus error in the xfsdump-2.0.1 source or
cat.c. I don't know where the message is coming from.

If there is something obviously wrong with my regime then what is it?
Otherwise, where do you suggest I look next?

Here is the output from xfsrestore:
