Strange behaviour with rsync and mounted truecrypt volume

[Oliver]

Hello,

when i mount a truecrpyt volume with truecrypt 5.1a and
synchronize  data locally with rsync (version 2.6.9  protocol version 29) like this way:

$ truecrypt myvolume.tc
$ rsync -av /home/oliver/myfolder /media/truecrypt

The myfolder is copied to /media/truecrypt like it should.
But when i dismount the truecrypt volume
and mount it again:

$ truecrypt -d /media/truecrypt
$ truecrypt myvolume.tc

And use the same rsync option on the unchanged myfolder again:
$ rsync -av /home/oliver/myfolder /media/truecrypt

rsync copies ALL files all over again a second time.
Even when all files should be allready in sync, because the data in the /home/oliver/myfolder folder was never changed.


Is this is bug or is this a problem with different partitions?
The virtual truecrypt volume is a fat32 partition, the /home/oliver/myfolder is on an ext3 partition.

The testdata in /home/oliver/myfolder is about 10 GByte in size consisting of about 500 files, some of them are over 100 MB large.
So this takes very long, when rsync is copying the same data
a second time.


I hope you can help me with this issue.

Best Regards,
 Oliver
