Mozilla Scheduled Maintenance - 3/14/2008,

Mozilla Scheduled Maintenance - 3/14/2008, 6:00am - 6:15am PDT (1300 -  
1315 UTC)

We will have a scheduled maintenance window Friday morning from 6:00am  
to 6:15am PDT.  The following changes will take place:

* 6:00am PDT (1300 UTC) - DNS for the stage.mozilla.org domain name  
will be changed to point at the new staging server.  No downtime is  
expected.

The following information is important to note:

* The SSH host keys from the old staging server have been copied to  
the new staging server to minimize disruption to automated scripts.   
In most cases you will get a harmless warning indicating that the new  
IP address is being added to your known_hosts file (because the domain  
name and the host key still match), and it will not require any user  
interaction. For reference, the host keys are:
1024 18:51:d0:c6:84:cb:a8:84:7c:59:ae:d3:da:00:32:a5 (DSA)
1024 ec:19:dd:bc:fc:96:0b:87:6c:bb:e8:26:02:73:75:c2 (RSA)

* The domain name stage-old.mozilla.org will continue to point at the  
old server until Tuesday March 25th. stage-old exists *now*. If you  
are nervous about the switch, you can change to using that name now  
until you get the guys to switch over. Just beware that you only have  
until March 25th to make the switch.  If you encounter any major  
problems communicating with the new server, you can change back to  
stage-old while you wait for it to get resolved, and file a bug in the  
Server Operations component to let us know what kind of problem you're  
having.

* The new staging server does *not* handle Breakpad symbol uploads  
from tinderboxes.  A new server has been set up at dm- 
symbolpush01.mozilla.org to handle these.  If your access to this  
server does not work, please file a bug in the Server Operations  
component, and fall back to using stage-old.mozilla.org until it is  
resolved. This server *will* have new SSH host keys you will have to  
accept. They are, for reference:
1024 78:86:be:c3:41:26:b0:aa:ee:c2:f5:6b:24:3f:47:a8 (DSA)
2048 7d:5b:5d:d0:0d:e0:b8:b1:b8:43:a1:3b:b6:26:c8:7b (RSA)

* The new staging server does not have any user home directories  
available.  There is no shell access.  You may only upload using rsync- 
over-ssh, scp, and a fairly broad set of file management commands  
passed as arguments to ssh (cp, ls, mv, rm, mkdir, chown, chmod, and  
others).  The only place you can upload is into the FTP tree, which is  
located at the path /pub/mozilla.org/.  There are symlinks at /home/ 
ftp and /data/ftp to keep old scripts happy.

* There are a LOT more details (and probably more information than you  
want to know) at the following blog posts:

Thanks,

Apologies for the late notice, but the tree will also be closed from 6am 
for a Talos configuration change. We hope to reopen it after 1 hour, but 
the cycle time of the windows tinderbox may push that beyond two.
