Hi all
I'm happy to let you know that new hardware has been ordered by Wikimedia
Deutschland and will arrive probably in about two weeks. We will get two new
systems:
* A more powerful web server, to replace hemlock: Sun Fire X4150, 2x Quad-Core
Xeon, 8GB RAM, 2x73GB SAS HDD. The current web server only has two cores.
* Another database server, to be used for S1 (english wikipedia), so S1 and S3
no longer have to share a server: Sun Fire X4250, 2x Quad-Core Xeon, 32GB RAM,
16x146GB SAS RAID.
This should improve performance and give us some head space for growth. Once the
new servers arrive, S3 will be re-imported too, so we will have live data again.
Any ideas for names? To stay with the nightshade theme, how about Jurubeba and
Erubia? Or perhaps we go the "witches' weed" way, with Datura and Mandrake?
Henbane is taken, i think. Amanita sounds nice, too :)
A third server has been ordered, which will also be installed in Amsterdam, but
will not be part of the toolserver cluster. It's a storage server (X4540, 24TB
RAID) that will keep a live backup of all media files.
Cheers,
Daniel

Hi,
There is currently a large amount of replication lag on the s2/s5 server. This
might be related to a failed disk which will be replaced next week. In the
mean time we will continue to monitor it.

Hi,
I will be restarting all MySQL servers later tonight / tomorrow morning (UTC).
For user databases (sql), there will be < 30 minutes downtime.
For -rr replicated database, there will be no downtime except on s2/s5, where
there will be < 30 minutes downtime.
For -user replicated databases, there will be < 30 minutes downtime.

Hi,
We are about to make two changes to the Solaris login servers:
* MySQL will be linked with libreadline instead of libeditline. The new MySQL
will be more compatible with MySQL on Linux, but will not be able to read
existing .mysql_history files previously created on Solaris. You may wish to
remove your existing .mysql_history file.
* The default Ruby (/usr/bin/ruby) will change from 1.9 to 1.8. Ruby 1.9 is
still available it /usr/bin/ruby1.9.

It seems that no one actually announced the creation of the
"newprojects" mailing list yet!
The mailing list[1] is an announcement-only list for new Wikimedia
wikis[2]. The way it works is that the addwiki.php[3] script that
sysadmins use to create the wikis automatically sends a mail to the
list, so (provided there are no bugs with the script) subscribers will
get an e-mail when every Wikimedia wiki is created.
This list should be especially useful for people who need to know when
new wikis are created so that they can update their tools or scripts.
Of course, people who are just interested in knowing about new wikis
are welcomed to subscribe too. :-)

Hello all,
I will reboot nightshade tonight at 22 o'clock UTC, because of an kernel-
update, The process will be visible at
https://jira.toolserver.org/browse/MNT-753
and there will be messages for the user, which are login, before.
Sinclery,
DaB.

Hi all! For a long time I wanted a decent push interface for RC-Events. Parsing
messages on IRC is unreliable, and polling the API sucks (and is also
unreliable, see Bug 24782).
So, I have written XMLRC <http://www.mediawiki.org/wiki/Extension:XMLRC> and set
up a prototype on the Toolserver - have a look at
<http://meta.wikimedia.org/wiki/Recentchanges_via_XMPP> for details. Basically,
you point any Jabber client to the chat room
<enwiki(a)conference.jabber.toolserver.org> to see the change events, like on IRC.
However, if you use a client aware of the extra data attached to the messages,
like <http://www.mediawiki.org/wiki/Extension:XMLRC/rcclient.py>, you will get
all the information you can get from the API (in fact, you can get the exact
same XML tag).
Try it out and let me know what you think!

Hi,
There was an outage of the Toolserver from around 2200h, 17th August until
around 0020h. The initial cause of the outage was a network issue at Wikimedia
(who provide us with transit). The network outage caused a cascading failure
of the two HA clusters (turnera/damiana and wolfsbane/ortelius), which
prolonged the outage by about 20 minutes.
The problem is now resolved and all services should be accessible again.
Although the cluster outage did not significantly extend the outage (since
cluster is quite good as recovering itself), it is nonetheless not something
that should have happened, and we will be reviewing the cluster setup to
prevent it happening in the future.

Hi,
It is now possible to specify the server type (RR or user) when using the 'sql'
script:
$ sql -u enwiki_p # Connect to user database
$ sql -r enwiki_p # Connect to RR database
If you currently use 'sql' for scripting, you should update your scripts to
specify one of these options. Currently, the default (if no option is
specified) is to connect to the obsolete sql-sX alias. This might change in
future.
