I have a teramac R310-1U from DNUK running 5.3-RELEASE-p1. It is the
only
server I have running 5.x. ISTR that the SiS chip set prevented me
loading
4.x.
The uptime of this server is good unless its under heavy load. When
MySQL
(with InnoDB) is being worked hard, the server will reboot after a
few hours.
However, build world will not crash it.
I have added the following to rc.conf:
dumpdev=/dev/ad0s1b
and the following to the kernel configuration file:
makeoptions DEBUG=-g
options KDB
options PANIC_REBOOT_WAIT_TIME=-1
I have also connected a serial console to the serial port and logged
in as
root.
I never get a dump file and I never get a message at the console. I
don't
know what else I can do other than strike this hardware vendor off my
list
and dump the server. This machine has already had its motherboard
replaced.
What about the power supply?
There has been quite a lot of traffic of late concerning so-called
spontaneous reboots and so far - *IIRC* - none of the incidents
were directly attributed to causes _other than_ balky power spupplies,
and in one recent case interestingly, a defective UPS!!
I think it's probably worth shoving a new PS in there, these days they
are far from expensive, in order to see if that eliminates further
instances of the problem.
I did consider that the previous time I was trying to get to the bottom
of the problem. The problem is easy to reproduce, simply by starting
mysqld and getting it to replicate.
I do not normally blame FreeBSD. I have been using it very successfully
for years in a production environment. This is the first server I have
had with this particular chip set, and I have read about problems with
the chip set in the past.
It seems to be disk related - it could certainly be a hardware fault
(cables or disk drive - as I said before, the motherboard has been
replaced already) - if anyone out there is successfully using this
hardware with FreeBSD, I could at least eliminate a device driver
related problem.
My other concern is that I do not understand why I do not get any
diagnostics.
I suppose much depends on whether or not you really want to -as you put
it - 'dump the server'. Should you elect to do so, please feel free to
ship it across the North Sea to me, I'll be happy to pay for the
shipping, deal with its little idiosyncracies and give it a second
life :-)
I will keep that in mind ;-)
