Concern: rsync failing to find some attributes in a file transfer?

I have a regular script I run to make static "snapshots" of my home
file system, with each being all the files that changed in the past 24 
hours.

I just moved my home partition to a new harddisk w/more space.

I ran the util and have gotten odd results each time I ran it.

This one bothers me... as I'm not sure why the attrs would be missing.

How can the names be transfered but no content?  Is that possible?

Ideas?

Thanks!

Why would or how would the files and attr-names get transfered but be 
missing?

I am not clear about the nature of this script.  Please provide more
details.

Home Partition?  Are we in 1995?  Why would you have a partition
mounted anywhere other than /boot ?

What util?  What results?

Is it really that just extended attributes are missing?  You seemed to
be in a panic.

I am uncertain what this question means.  Maybe I have interpreted the
rest of your email in the wrong context.  Maybe not.  I am not sure.
Please provide technical details.

Concern: rsync failing to find some attributes in a file transfer?

Give 3.1.1 a try -- it has a fix in it for miss-sorted attr names when
running as non-root.  Alternately, try running (at least the receiving
side) as root.  Here's the NEWS entry for this fix:

- Fixed a bug in the xattr-finding code that could make a non-root-run
receiver not able to find some xattr numbers.
