I recently discovered that my /var partition is not going to be large enough
to accomodate my queue at certain times, and was hoping for some insight.
As a temporary fix, I moved the queue to another partition (/home of all
places) and created a symbolic link. I realize that there are some security
concerns with this solution, so I am seeking advice. Is there a
(reasonably) safe utility to resize my partitions without starting over
(which is not really an option)? Is there another acceptable place to store
the queue? And if so, is a symbolic link acceptable, or should I recompile
to reflect the new queue location? Are there performance concerns here?
Here's my partition table, and the output of 'df' for your consideration.
The system is RedHat 7.0.
partition table:

The cause of the large queue is a mailing list that sends about 150,000
messages at 10-25k per message once a week (via qmail's replacement for
sendmail), so I figure I'll bring up the large queue problem as well. I
know this borders on an FAQ, but what I'm not sure of is this--is there
/any/ way to avoid the queue size limit of 20ish thousand messages? As I
understand it, the big-todo patch doesn't actually solve it, it just splits
up the todo directory, and conf-split is only able to increase performance.
Please tell me I'm wrong, because I'm not /positive/ that this will be an
avoidable problem in the future.
Thanks to everyone for any suggestions they can offer.
