rsync hangs on checksum synchronization

[jojo <cooljojo at gmx dot net>]

Hi everybody,

I'm experiencing another variant of the rsync hang-problem. I'm using rsync
locally to synchronize some large amount of data (~ 80 GB of media files)
with an attached USB harddrive. The command I use for everyday
synchronization reads as:

rsync -CvubrltgoD -v --delete --backup-dir=/CYGDRIVE/p/BACKUP
--exclude="System Volume Information" --exclude="RECYCLER"
--exclude="desktop.ini" --stats --progress /CYGDRIVE/m/ /CYGDRIVE/$1

This command just works as expected - no problems occur. However, I want to
run a cron job every month that performs a thorough, binary comparison
between the two trees. The command reads as:

rsync -cCvubrltgoD -v -v --delete --backup-dir=/CYGDRIVE/p/BACKUP
--exclude="System Volume Information" --exclude="RECYCLER"
--exclude="desktop.ini" --stats --progress /CYGDRIVE/m/ /CYGDRIVE/$1

As you will notice, the only noticeable difference is the additional
"-c"-switch which implies the use of checksums.

Running the second command results in a large list being built (locally,
>from /CYGDRIVE/m/), which soon stops after about 100 files. The point where
it stops is not identical all the time.

I don't know if I should attach the result of the cygcheck-command here
since it contains a large amount of data - if you need any more information,
please ask me to provide it. Google could not help me in this issue, and I
can't see why the command in question should not work.

Yours, truly


Michael
