Hi, Thanks again for the detailed reply!
See the very bottom of my mail. I don't believe the PSU is the problem, after reviewing your SMART statistics.
Ok, I'll stick to the one I have then, for now.
My other (on-board) SATA controller is a VIA controller; and I've never had any problems with it (although the hardware raid messed up once a year or 2 ago, and since then I've been using software raid without any issues).Okay, so you've got an onboard VIA (VT6410) SATA controller, an onboard VIA IDE controller, and a PCI SATA controller. I'd still like to know which disks are attached to what controller, and if any of the devices are sharing IRQs. Can you provide the output from the following two commands? dmesg | egrep 'atapci|(ad|ata)[0-9]+' vmstat -i I'm just trying to narrow stuff down.
Allright, attached is the output to both of these commands.
It's interesting that the disks which are giving you trouble are Samsung disks. There's some history here which you should be made aware of: In July, Daniel Eriksson reported data corruption occurring with his nVidia MCP55 chipset when 1TB Samsung disks were attached to it. The same disks on another controller performed fine. The corruption was being detected by ZFS as checksum errors. (UFS/UFS2 won't detect this sort of thing, unless the corruption is occurring somewhere within the filesystem tables.) http://lists.freebsd.org/pipermail/freebsd-stable/2008-July/043427.html Soren Schmidt (ata(4) author) replied that there are some nVidia chipset-related fixes for ATA in -CURRENT, and provided a patch. Daniel reported that the patch made absolutely no difference: http://lists.freebsd.org/pipermail/freebsd-stable/2008-July/043434.html Daniel also tried using a firmware patch for his Samsung disks, which limit the SATA speed to SATA150, but the speed was still negotiated as SATA300 (indicating the vendors' own f/w patch is broken, or FreeBSD does not play well with it). The f/w patch didn't fix his problem either: http://lists.freebsd.org/pipermail/freebsd-stable/2008-July/043432.html [EMAIL PROTECTED] reported using his MCP55 controller without any problem -- as long as he didn't use Samsung disks. He stated that he believes Samsung disks are PATA disks that use a PATA-to-SATA adapter inside of the drive, leading to problems (and yes, those adapters are known to cause all sorts of mayhem): http://lists.freebsd.org/pipermail/freebsd-stable/2008-July/043485.html I'm not sure what became of the thread; Daniel never provided a post-mortem. I'm left to believe he probably took [EMAIL PROTECTED]'s advice and switched to another disk vendor.
Gee, I that's a whole list. Before today I didn't know that there was that much difference between disk vendors (especially in terms of compatibility). I'll keep that in mind when I buy new disks. Thing is I've had a bunch of disks (Maxtor, Seagate, Western Digitals, Samsung, etc), but I've had bad experiences with both Seagate and Western Digital. (Basically, I've never had a Seagate last me more than 2 years (laptop drives), and I had a raid5 array of WD's of which 3 crashed within 2 years). Never had much trouble with Maxtor or Samsung yet, but obviously take this all with a grain of salt, because 10 disks don't make solid statistics.
Thanks for upgrading to 5.38. All the SMART statistics for these disks look okay.
No problem, thanks for looking into this in so much detail!
Can you run some SMART tests on the disks? You can run these tests while the disks are in use (but I/O will make the test take longer to complete): smartctl -t short /dev/ad4 smartctl -t short /dev/ad6 Then you'll need to look at the SMART self test log, as well as the SMART error log, to see if anything is returned. Make sure the tests have completed (the Status field should be "Completed without error", unless an error was found of course): smartctl -a /dev/ad4 smartctl -a /dev/ad6
I attached the output below, the tests passed. But I thought I'd reply that you know I'm on it. Currently I'm running the offline tests, but they will take another 3 hours at least to complete. Will get you the output of those as soon as they're done.
If nothing is found, try a different test (also safe to run during operation; don't let the word "offline" scare you), and repeat looking at the logs once more. This test may take some time, though: smartctl -t offline /dev/ad4 smartctl -t offline /dev/ad6 At this point, I'm inclined to believe the issue is specific to those Samsung disks. I do not believe your PSU is a problem; the SMART statistics would be showing a higher number of power-cycles if the disks were losing power. Worth noting (about Samsung disks) is that smartctl has options to work around 3 different firmware bugs. The bugs are SMART statistics-related, but those kind of mistakes don't give me "warm fuzzies". Be wary. :-)
Nope, that definitely does not give great confidence.I still haven't switched the disks with respect to the controller, but since I have very little knowledge of disk debugging, I'll follow up on your suggestions first.
