rsync hanging in read-batch mode

[Terry Brown]

Trying to do something like this, in Ubuntu 11.10/12.04:

Location A

(work occurs changing files)

rsync --write-batch /media/bkup/foo.rsb /path/to/files/ /path/to/copy/

Location B

rsync --read-batch /media/bkup/foo.rsb /path/to/files/
rsync --read-batch /media/bkup/foo.rsb /path/to/copy/

(work occurs changing files)

rsync --write-batch /media/bkup/foo.rsb /path/to/files/ /path/to/copy/

Location A

rsync --read-batch /media/bkup/foo.rsb /path/to/files/
rsync --read-batch /media/bkup/foo.rsb /path/to/copy/

return to top


there are two directories I'm trying to do this with, the one that is "just files", and symlinks etc.,
works ok, but the one the includes /home/ hangs during read-batch.  I sort of wonder if it's related to
strange things in the filesystem like .gvfs and filesystem mount points - just speculation.



using a recent compile of rsync:

cat rsync_dbg.sh

ulimit -c unlimited

# Some systems have "truss" or "tusc" instead of "strace".
# The -f option tells strace to follow children too.
# The -o option tells strace where to send its output.
strace -f -o /tmp/rsync-$$.out /home/tbrown/Package/rsync/rsync/rsync "${@}"


. rsync_dbg.sh --exclude .smb --exclude .gvfs --exclude 'Ubuntu One' --exclude 'Dropbox' --one-file-system --verbose --archive --progress --human-readable --archive --delete --ignore-errors --read-batch /media/bkup64/bkup/trans/usr1.rsb /mnt/usr1/usr1/


(the same flags were used for the write batch)


after a few files being synced, everything seems to stop and dstat confims nothing is happening.


netstat -p | grep sync

Ctrl-C in original terminal

I don't want to post the output of strace to the list, it contains listings of contents of /home/*
but I'll send it to a developer if they ask for it.
