Hi all

( I resubmit a mail to the Centos-morror List for your information) (sorry to sent again, because previous one was sorted in the different thread in the ML archives)

Hi,

http://ftp.riken.jp/Linux/centos/ is being listed as 12 days late.

Any issue on your mirror or on the centos mirror your are pulling from?

Best regards,

Tru

Hi

Yes, we ftp.riken.jp are pulling from the CentOS master site by rsync -avzH --delete msync.centos.org::CentOS-incdvd /ftp/Linux/centos

every 4 hours when the previous rsync to msync.centos.org::CentOS-incdvd is not running. In addition, we kill the previous rsync once a day if there is a previous rsync to msync.centos.org::CentOS-incdvd running and start a new rsync to msync.centos.org::CentOS-incdvd .

A part of the last rsync log is as follows.

It seems that the time stamps obtained by pulling the msync.centos.org::CentOS-incdvd seems to be sometimes wrong at some conditions.

At the Centos archive directory at ftp.riken.jp the time stamps are now as follows.

[ftp centos]$ pwd /ftp/Linux/centos [ftp centos]$ date -u Tue Apr 21 13:21:06 UTC 2009 [ftp centos]$ cat TIME 1239274801 [ftp centos]$ cat timestamp.txt Thu Apr 9 11:00:01 UTC 2009 [ftp centos]$ ----------------- Manual rsync to msync.centos.org::CentOS-incdvd/ right now resulted

[ftp centos]$ pwd /ftp/Linux/centos rsync msync.centos.org::CentOS-incdvd/TIME . rsync msync.centos.org::CentOS-incdvd/timestamp.txt . [ftp centos]$ cat TIME 1239274801 [ftp centos]$ cat timestamp.txt Thu Apr 9 11:00:01 UTC 2009 [ftp centos]$ date -u Tue Apr 21 13:24:29 UTC 2009

----------------------------------------- Manual rsync to msync.centos.org::CentOS/ right now resulted

rsync msync.centos.org::CentOS/timestamp.txt . rsync msync.centos.org::CentOS/TIME . [ftp centos]$ cat TIME 1240320001 [ftp centos]$ cat timestamp.txt Tue Apr 21 13:20:01 UTC 2009 [ftp centos]$

---------------------------------------------

I remember that the mirror ages of ftp.riken.jp was 3 hours yesterday or the day before yesterday.

But now there are several sites which mirror ages are 12.1-12.2 days now including ftp.riken.jp.

So I think the time stamps obtained by msync.centos.org::CentOS-incdvd is sometimes wrong (12.x days ago) while timestamps obtained by msync.centos.org::CentOS is always correct.

For the temporary solution to this problem, I added the rsync msync.centos.org::CentOS/timestamp.txt /ftp/Linux/centos/ rsync msync.centos.org::CentOS/TIME /ftp/Linux/centos/ after the rsync -avzH --delete msync.centos.org::CentOS-incdvd /ftp/Linux/centos command in the daily mirror script.
