Hi all. I have a strange issue with sync'ing from a USB-attached ext4
file system on one machine, to a USB-attached ext3 file system on another.
The sync works fine (a few thousand files). If I run it again straight
away, or a few minutes later, rsync reports no action required.
But if I wait for a few hours and run it again it copies all the files
again.
I'm trying to determine what's making it think the files are not
up-to-date. I have all the debug flags turned on. Am I missing something
that will let me know what rsync is thinking?
My command-line is:
rsync --info=all4 --debug=all4 -auvz --modify-window=1 ./src/dir/
server:path/to/dst/dir/
On the good run I see this in the output:
...
generator starting pid=3205
delta-transmission enabled
recv_generator(.,0)
recv_generator(.,1)
recv_generator(604-001-bg.jpg,2)
604-001-bg.jpg is uptodate
recv_generator(604-001-l.jpg,3)
604-001-l.jpg is uptodate
recv_generator(604-001-m.jpg,4)
604-001-m.jpg is uptodate
...
and on the later run when everything is copied again I see this:
...
generator starting pid=10544
delta-transmission enabled
recv_generator(.,0)
set modtime of . to (1282081725) Wed Aug 18 07:48:45 2010
recv_generator(.,1)
recv_generator(604-001-bg.jpg,2)
recv_generator(604-001-l.jpg,3)
recv_generator(604-001-m.jpg,4)
...
I've just noticed that "set modtime" differs between the two runs. If I
do an ls now on that directory I get:
$ ls -ld --time-style=full-iso 604

Sorry for the long post. This issue has been driving me crazy.
Dave.
