Hi Matthew,
I'm running 7.2-RELEASE-p4 on an i386 HP server (ML G5) in RAID1
configuration. Very recently, I've seen IO errors such as:
ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=20472527
reported and the RAID mirror is now offline.
ad0: TIMEOUT - WRITE_DMA48 retrying (1 retry left)
Hi Jeremy,
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 too much can cause odd things
to
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,
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 doing
that than actually serving ov
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 be
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 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 e
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 o

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:
