Hello,

my FreeBSD 5.4 box with gives me strange messages concerning Adaptec 
SCSI adapter 29320 (ahd):

Could it be problem with this Seagate ST336754LW? I have firmware 003 in 
this drive from Seagate, about 2 months old, but problem persist.
Is this a drive problem or controller problem? I read messages from 
Robert and his problems with Adaptec 39320 and DELL SC430, so i tried 
command camcontrol tags da0 -N 32, but no change.


Thanks for help.
Complete dmesg and messages included.


Tomas

[NNOT] Stability on Soekris class h/w? (was Re: 6.0-BETA2 as reliable webserver?)

The toy is currently set up with FreeBSD 6.0-BETA2, Apache 2.0,  
MySQL 5.0
and PHP-5.0 with all the reasonable modules. Everything is  
compiled from

ports. No changes to the kernel yet, no world-rebuilding done.



I'd also be extremely loath to bet my company on a laptop running beta
software.  As others have pointed out, laptops aren't designed for
this.  (Though my old Compaq laptop ran FreeBSD 24x7 for several years
and I only stopped using it because the lid was cracking too badly).


Yeah, I've had my home server running on an old iBook (not FreeBSD).  
I had replaced the original disk with a larger used one because the  
original was just 6GB. The used disk lasted only a year. Had to open  
it back up and put the 6GB drive back in until I can afford a new  
disk (or a Mac Mini). I need to add RAM to that poor child, too.


That said, 512 MB RAM in the HP notebook might leave enough RAM for a  
RAM disk. One could mirror Apache, PHP, MySQL (app, not DB),  
libraries, and the web app itself onto a RAM disk. That way the  
server could respond to initial hits out of the RAM disk while the HD  
is spinning up.



If you're really concerned about noise:
- use an older desktop and maybe even underclock it to keep it cooler
- build your own system.  Either go the low power route (mini-ITX) so
  you don't need noisy fans or use an over-rated PSU and CPU heatsink
  to keep fan speed (and noise) down.  In either case, you'll need to
  look around to find a quiet HDD.


So, what's the stability of FreeBSD 5.x/6.x on Soekris  class hardware?

I'm thinking especially in terms of mulit-port nics that would  
support bridging, etc.



- [as a completely left-field suggestion] look at something like an
  Apple G5 system - large fans running slowly generate very little  
noise.


Maybe even Mac Mini? ;->

fbsd on PPC is still not even close to stable, and the iNTEL Macs are  
still at least ten months away. But openBSD and netBSD run rather  
well on PPC if the eye candy of Mac OS X is unpleasant or the cost of  
Mac OS X Server (for a little added peace of mind?) is uncomfortable.

broken fxp driver in 4.x ...

[Marc G. Fournier]

Several months ago, on one of our servers, we had an issue where if we 
moved an IP between the servers, the 'ifconfig alias' on the server with 
the em device seemed to 'hang' for 60 seconds or so (instead of coming 
back right away like the other servers), and, for some reason, it didn't 
send the arp out onto the network properly, so upstream routers weren't 
being made aware of the change ...


Subsequent cvsup updates of the 4.x tree eventually got rid of that issue, 
and the problem went away ...


Now, on one of our newer servers runnign a fairly recent cvsup of 4.x, the 
fxp driver is doing the exact same thing ... all the other fxp based 
servers do a nice quick 'ifconfig alias' for an IP, and arp broadcasts are 
sent out, but on this one, I get the '60 second hang' and have to get our 
network guys to clear arp caches for  the changes to take effect :(


Has anyone else running 4.x experienced this?  Or am I just unlucky with 
these things?  Is there a way of fixing it?


Thanks ...

STABLE-4 is VERY good and my advice for you - use it instead of any
beta's... MySQL v5 is good but greedy one. You'll need ALOT of memory. And
Apache2 - it's just a question of taste. Frequently speaking - I'm still
using Apache1 and it works pretty stable and fine...
