[CentOS-mirror] Flip-Floping contents at msync.centos.org::CentOS-incdvd [ Re: flip-flopping timestamp by pulling CentOS [Re: Wrong timestamp by pulling CentOS-incdvd

Hi Tru, and CentOS master mirror server Admin.

Our user notified that the contents of Centos 4 at our ftp server
ftp.riken.jp is flip-flopping between new one and old one in these few

We already noticed that the time stamp was flip-flopping before
in this Mailing list as:

On 09.5.5 0:13 PM (UT+9)
[CentOS-mirror] flip-flopping timestamp by pulling CentOS [Re: Wrong
timestamp by pulling CentOS-incdvd

On 09.4.21 11:28 PM (UT+9)
[CentOS-mirror] Wrong timestamp by pulling CentOS-incdvd

But It was not only the time stamp, but also all the contents at
msync.centos.org::CentOS-incdvd seems to be flip flopping till now.

Could you please look into and fix this problem ?

We are now now mirroring using the script below, since we
cannot believe the time stamp at msync.centos.org::CentOS-incdvd.

rsync -avzH --delete --exclude=timestamp.txt --exclude=TIME
--exclude=".~tmp~/" msync.centos.org::CentOS-incdvd /ftp/Linux/centos
date -u > /ftp/Linux/centos/timestamp.txt
date +%s > /ftp/Linux/centos/TIME

For example, same file was deleted and created and deleted and created
in our rsync log to msync.centos.org::CentOS-incdvd. (We are rsyncing
to msync.centos.org::CentOS-incdvd every 4 hours if the previous rsync
process does not exit)

A part of the rsync log is shown below.

CentOS.log: 2.1/updates/headers/tzdata-0-2009f-1.el2_1.noarch.hdr
CentOS.log.4 :deleting 2.1/updates/headers/tzdata-0-2009f-1.el2_1.noarch.hdr
CentOS.log:8 2.1/updates/headers/tzdata-0-2009f-1.el2_1.noarch.hdr
CentOS.log.17 :deleting

(time zone of the log files beleow is JST = UT+8)
-rw-rw-r-- 1 archive archive 30662 May 19 18:42 CentOS.log
-rw-rw-r-- 1 archive archive 91659 May 19 18:15 CentOS.log.4
-rw-rw-r-- 1 archive archive 84518 May 19 18:03 CentOS.log.8
-rw-rw-r-- 1 archive archive 91493 May 18 18:24 CentOS.log.17

Thank you in advance.
