Hi Jeremy,
SNIP: both old disks were fine
Anyway, if heavy disk/controller load appears to be causing these
problems, you could have power-related issues. Possibly the combination
of two disks + heavy I/O causes enough power draw that the ICH9 starts
to behave oddly. Voltages which deviate
Hi Jeremy,
Lots to say about all of this.
Thanks for your elaborate reply, it was very useful to see smartctl
output explained a bit :) I still think there's something else in play
beside disk failure. I've checked one of the drives I replaced earlier,
but that one doesn't have any of the
Hi Terry,
I have a bunch of R300's here. From one that is using the on-board SATA
and 2 drives in a gmirror setup (very similar to the OP) after 18 hours
of uptime:

Hi there,
what kind of disk I/O is going on. If actual I/O is very little, then
something weird is going on with regards to the number of interrupts
being seen on IRQ 23. mav@ might have some ideas, otherwise I'd
recommend rebooting the machine and seeing if the number drops. If so,
it may
Interesting. Which version of FreeBSD is this system running? I guess
you didn't experience any of the timeouts I'm seeing?
8-STABLE as of the 11th of this month, or thereabouts. No, I've never
seen a disk timeout on that box.
Yeah, this R300 was bought second-hand and unfortunately the

Hi,
SNIP: disk without errors timing out
That could be caused by a multitude of other known things. For
example, some Western Digital Green drives (including the
Enterprise class ones) are known to perform head parking/offloading
excessively, which could result in the drive spending more time
Attached the SMART output of both disks I replaced about a month ago. It
appears I replaced perfectly fine drives with the current disks with
errors ;( One of the old disks is in a USB-enclosure now, so 'da0'.
Let's send those attachments, then.

Hi list,
I'm running FreeBSD 8.0-RELEASE-p1 on a Dell R300 which has a ICH9 SATA
controller on-board (do not have the RAID controller).
The system has 2 disks in a gmirror setup. Every now and then, probably
under some load, one of the disks gets read or write timeouts like:

My question: does anyone have experience with FreeBSD on a Dell R300
or can anyone give me some help in trying to fix the timeouts?
Could you please do the following:
- Provide output from vmstat -i
- Provide output from dmesg | grep -i ata
- Install ports/sysutils/smartmontools (5.40 or
