Due to the split of mirrors with cAos , it will be necessary for mirrors
to make some changes to the way that they mirror the CentOS tree, as
moving forward it will no longer be a part of the caosity tree.
Firstly mirrors need to decide whether they are mirroring CentOS or cAos
or both. They are distinct operating systems, CentOS is a rebuild of
Enterprise Linux , whereas cAos is an rpm based distribution in its own
right.
For more information see www.centos.org or caos.caosity.org
At present both trees are mirrored with a single rsync of
mirror.caosity.org::cAos - moving forward two rsyncs will be needed :-
mirror.caosity.org::caosity that will get the caos tree
and
msync.centos.org::CentOS that will get the CentOS tree
Please note that at present CentOS will be listed and stored within the
cAos tree, this should not be the case in the future - CentOS should never
be stored or listed as a part of cAos or caosity.
Mirror Changes
--------------
In order to achieve the changes required with minimum download bandwidth
the following steps should be carried out. (Note that individual
circumstances may vary - if in doubt do nothing and ask) .
1. Stop cron based rsync job from syncing
2. Move the CentOS tree to its new location, which should be at the root
of the publically served tree.
This can either be achieved with 'mv' or if you want a 2nd chance at it
'cp -al' which will create a hardlinked copy of the tree (as long as it
is on the same partition)
eg with directory structure /pub
/pub/caos
/pub/caos/centos
cp -al /pub/caos/centos /pub/
or
mv /pub/caos/centos /pub
to end up with /pub/
/pub/caos
/pub/centos
(and /pub/caos/centos/ if using cp -al)
3. Create a new rsync cron job to sync the CentOS tree (if required) .
This should be something like :-
rsync -aqzH --delete msync.centos.org::CentOS /pub/
*** note the change to msync.centos.org *** mirror.centos.org is
deprecated for rsync use - to allow us to use different servers for yum
mirrors.
please use rsync -anvzH --delete msync.centos.org::CentOS /pub/
first to test that the command will do the right thing ('n' is dry run
and will just show what wil be transferred - which in theory should be very
little - if it says 40 GB + then the command is wrong !!)
Note that due to the way that rsync works any updates will only be written
to this new tree and not the hardlinked tree left behind if using cp -al
above ( that can be deleted once you are happy with the new location
working).
4. Create a new rsync cron job to sync the cAos tree (if required). This
should be something like :-
rsync -aqzH --delete mirror.caosity.org::caosity /pub/
*** note the change to ::caosity - ::cAos will still sync both trees
for mirrors that havent restructured yet. ***
This will also delete the CentOS tree left underneath the caos tree
above.
You should now have both trees in the correct places.
5. Please email the list to say that you have restructured your mirror and
what the new urls will be for public use. We will update the databases to
reflect these new locations.
6. It is not necessary to mirror all of centos if you do not wish to - eg
you can choose whether to carry 2.1 , 3.3, 3.4, 4.0 - but please note in
the email any trees that you will not be carrying and we will note that in
the database.
7. In the very near future we will be restricting access to
msync.centos.org to publically listed mirrors only - we have to establiush
a way for new mirrors to sync first though.
8. We will be tracking which mirrors have/havent restructured and will
contact individual mirrors accordingly.
There is now an irc channel - #centos-mirror
on irc.freenode.net where mirroring discussions may be held.

Hi guys,
Just a quick note of advance(!) notice : CentOS 4.1 tree is starting to
be populated with the IA64 branch. i386 and x86_64 will start shortly
and complete in 72 to 96 hrs times. We are looking at an approximate
size increase of 4 to 5 GB for the /centos/4/ tree.
We will try and ensure there is a lag, from the time the pkgs are
uploaded, to the Announcement itself, allowing the mirrors to catch up.
To save on mirror space, duplicate packages in 4.1 will be hardlinked
against pkgs in 4.0 ( please check your rsync lines, make sure there is
an -H option there ).
Further, once the 4.1 iso's are available on the mirrors, iso's for 4.0
will be removed from the mirrors right away. They will still be
available on BitTorrent for an over-lap period of 14 days, should anyone
need them.
Once this 14 day over-lap is over, the entire 4.0 tree will be removed
from the mirrors and /centos/4/ will be pointing at /centos/4.1/
Thank you all, once again, for hosting mirrors for the CentOS Project.

Hello,
I sent this message in a few days ago, however I haven't seen it ever come
up on the digest. The Versaweb Hosting CentOS mirror is back online and
available for public use. The info is as follows:
Organization: Versaweb Hosting - http://www.versaweb.net
<http://www.versaweb.net/>
http://mirrors.versaweb.net/centos/ftp://mirrors.versaweb.net/centos/
Location: San Jose, CA USA
Port Speed: 100mbit
We are syncing 4 times per day from the US master server.
Our mirror is running CentOS 4.0 X86_64 as well :-)
Thanks, and everyone keep up the good work!

Hello,
We have setup a CentOS mirror, information follows below.
City: Ashburn, VA
Country: USA
Bandwidth: 1000Mbit/s
Updates: 4 times a day
Mirror URL: ftp://ftp.ptptech.com/pub/CentOS
As you will have read in a recent post, the CentOS mirror system is
separating from cAos so as to be an independent project in its own right.
There will be more information regarding how to change the mirror setup
and where to sync from shortly, however for now we are creating new
mailing lists.
If you were subscribed to the caos-mirror mailing list then you will jave
been subscribed to this list automatically. (If not - apologies).
The options you subscribed with should be maintained - although your
password will have changed.
If you want to know the password that has been set in order to login and
change options then you can have it emailled to you here :-

I already replied to this kind of question :
simply do a dry run with rsync with the verbose option.
The last numbers give the total size of what would have been tranferred.
man rync :
-n, --dry-run show what would have been transferred

Hello all,
I'm interested in setting up a mirror, however I couldn't find the
total size of everything (without downloading it). Could someone
reply with the sizes of the 3.4 and 4.0 subdirectories ?
should be as simple as " find /path/to/mirror/centos -type d -exec du
-shS {} \; "
Also, how can I search the archives of this mailing list ?
(I would like to know preferred cron method for rsync, and howto
configure yum to point to my mirror)
thanks,
-Jason

Hello,
Versaweb's CentOS mirror is back online and available for public use -
please add it back on to the mirrors list. We have upgraded to a brand new
server to make the mirror considerably faster and more reliable, and as a
result it should handle a greater number of simultaneous users now as well.

This is not the right list.
Try centos(a)centos.org
This one is for mirroring issues.

Can you please add 138.23.169.46 to the list of available mirrors for t3
or faster? We ave resolved our routing issues. Also, our access to the
main mirror needs to be resolved as well. Thanks.
