comment Adding Additional RAID Array to Ubuntu 11.10 x64 Server
under the above circumstances yes. Your sites would be on a Logical Volume. After adding the new array, you would just extend the volume to include the new array. You can them remove the old array (if you wanted) by removing that physical volume from the logical volume. LVM will migrate the data in the background without affecting the website. There will of course be some performance degradation though.

comment web server very slow, bombarded with php-cgi processes?
Glad to be of help. Unless its a db heavy website or a lower-spec server, the MySQL CPU usage may also be worth looking at. Maybe some indexes could help ;-)

comment Trace a process on a Linux box
this is a great idea that I never thought of. perhaps a symlink to /dev/random would work if pureftpd follows symlinks. Then it will be held indefinitely. You would of course need to kill the process fairly quickly or you might run out of memory.

comment Does using a 'foreign' domain as email sender reduce email reputation?
yes, that is correct. I do not believe it would stop it from being marked as spam though it should decrease the chances of it being marked as spam.

If we look at your snapshot of top, your total cpu usage is at ~77%. mysql is at ~26%. The rest of the lines are php-cgi. Assuming this holds true for the rest of the processes, it seems that php-cgi is using ~51% of your cpu. This is far too high for a php app with 200-300 active users. consider changing from php-cgi and also take a look at solutions like apc (php.net/manual/en/book.apc.php)

your server doesn't have to be in the blacklist... another server in the same block being blacklisted is enough to block you. This holds even if the other server has nothing to do with you. The fact that they are both on the same block is enough...
