[cobalt-users] CMU Error

[Jason Vaughan <cobaltlist@xxxxxxxxxxx>]

We have recently purchased an Antefacto S1000c. this is a High 
Availability Appliance, which mirrors pairs of Raq 3s or 4s. Should 
one fail, the other takes over without hesitation.

In order to use it, we first had to do a cmu export of our existing 
Raq and import the contents on a new one. Next we had to change the 
ip addresses as the Raqs behind the antefacto have internal 192 
addresses. This was easy as we just did a find and replace in the 
cmu.xml file.

Once the Antefacto is configured, the server should perform as 
before. we can then add a duplicate machine and tell it to mirror the 
content.

What this exercise has brought up is a few issues with the CMU export script.

Any custom changes to the original box may not be copied across.

For example we had enable ETRN. This vanished with the CMU import.

Solution: go to /etc/mail/ and tar up the sendmail.cf, mailertable 
and mailertable.db. FTP this to the new box and untar in the 
/etc/mail directory.

As .htaccess files are not supported by default, you will need to 
modify the /etc/httpd/conf/access.conf by commenting out 
AllowOverride AuthConfig Indexes Limit and adding a new line, as 
follows:

#AllowOverride AuthConfig Indexes Limit
AllowOverride All

The next problem which I have seen three times in the list without 
solution, is an error which crops up after doing a cmu import:

<snip>
Message from syslogd@is7 at Thu Feb 28 10:15:13 2002 ...
is1 procmail[9903]: Couldn't rename bogus 
"/home/sites/site10/../../spool/mail/jo.blogs" into 
"/var/spool/mail/BOGUS.jo.blogs.QhrB"
<snip>

this appears every few seconds in the terminal window and also 
appears in bounced messages.

In /home/mail, the entry was:

-rw-------   1 185      site9      20861 Feb 26 22:25 jo.blogs

However, in /etc/passwd, the entry was:

jo.blogs:x:189:100:Jo Blogs:/home/sites/site10/users/jo.blogs:/bin/badsh

Jo Blogs is actually in site10. Therefore changing the group to 
site10 and the owner to 189 fixed the problem.
chown 189 jo.blogs
chgrp site10 jo.blogs

It may be an idea for someone to add a check in CMU import, after the 
script has run, to check that the owner or each file in 
/home/spool/mail is the same as the file name i.e:

-rw-------   1 185      site9      20861 Feb 26 22:25 jo.blogs is wrong.
-rw-------   1 jo.blogs      site9      20861 Feb 26 22:25 jo.blogs is correct.

I have spent a few hours fixing these problems so I hope this makes 
life a little easier for everyone else out there!
