Hi,
I followed http://people.freebsd.org/~rse/mirror/ to create a software
RAID mirror. I have two 75G drives in the machine. I allocated 74G to
the filesystem on each drive and 1 G to swap. When I blanked ad1 and

drive. Can

Hi all,
I'm running 4.11 on a server, and for the last week or so it has been
spontaneously rebooting about once a day or so. It has 512M of memory.
I ran memtest and it causes the reboot as well. I went and bought 2 sticks of
memory, took out the old one, and put the new ones in. That gave

Hi,
Simple question really... Can you ever have to much swap space?
We're sitting with quite a nifty P4 System with 1GB Ram. We will more than
likely add another 2 or 3GB in the month to come as our applications (mainly
perl) are consuming vast amounts of memory and swap.
We made the mistake

Only if there are better things you can do with that disk (or money.)
In this case, RAM might be a better priority, see below.
We're sitting with quite a nifty P4
We made the mistake however of just allocating 512MB swap as we did not
know accurately at the time of installation what the resouce requires are
going to be (especially not that it would be this high).
A traditional rule of thumb is to have 1x - 2x the total RAM size in
swap space. This assures
Actually having a separated disk for swap should increase your performance.
But my opinion is that if you really need *all* the 40 GB of swap when your
system's ram is 3 GB, you won't see the difference: most of the data your
system needs is swapped out!
You could add a partition to your new

So now I'm trying to swap the ports at the kernel level so that
the LCD control characters and data which went to the mb port
com2 (sio1) go to com2 (sio0), and the console output moves
from com1 (sio0) to com1 (sio1).
I've tried
b) device sio0at isa? port IO_COM2 irq 3
b
sio0at isa? port IO_COM1 flags 0x10 irq 4
a) device sio1at isa? port IO_COM2 irq 3
a) device sio2at isa? disable port IO_COM3 irq 5
a) device sio3at isa? disable port IO_COM4 irq 9
So now I'm trying to swap the ports at the kernel level
This is probably a dumb question, but it's been a long time since my OS
theory classes. ;-)
How can I get a page fault if swap space is never used? Why would anything
be swapped out and yet not appear as usage on the swap partition, since that
never goes away once used?

Ah, yes. I think I remember now. You don't actually 'load' all

I have a freebsd 5.3 system that ocassionally panics on shutdown so I
thought it might be good to get a core dump of it. Since I don't have a
partition decidated for that, I thought I might be able to use my swap
partition for it since it's twice the size of my ram and that it's useless
Loren M. Lang writes:
Looking through the system startup scripts I discovered that the
system runs a program called savecore that save a core dump to a
file in /var/crash from a previous crash. The problem is that
this is run after swap has been turned on.
True.
However
is true. What about the swap
partition? Is it simply bypassed, or does one need to do something to
create an encrypted swap partition?

The partition itself is encrypted so it doesn't matter whether the

Thanks Alex,

No cleartext ever touches the hard drive's platter.
But I wonder if that last sentence is true. What about the swap
partition? Is it simply bypassed, or does one need to do something to
create an encrypted swap partition?

im getting this all the time and the load of the ded goes badly high like 300/400
then goes down from nothing cause it found a avaiable peace of ram .. what this
could be ? probably in the paritcion of swap ?
Could be a failing drive.

I guess it will depend a lot on the hardware you have, but you probably
want to try one or both of 'camcontrol stop' or 'camcontrol eject' before
pulling the drive. One of these should spin the drive down and leave it
in a safe state to be removed.
this is exactly what i was looking
