Re: Sudden wierd SATA problem on RELENG_7 (Re: ZFS hanging at kernel boot now, but didn't before... (Re: ZFS MFC heads up))
This appears to have gone away now. I unplugged the bay that was causing the trouble, and the system booted just fine on the remaining 4 drives. Then I plugged the bay back in (live) and did an atacontrol detach/attach on that bus (I wonder why I always have to do that). The drive was seen, and ZFS resilvered itself. I'm doing a ZFS scrub now to make sure that everything is good, and I'll do a reboot and see if it's all ok after that. Strange, so it looks like a cable might have got a little loose or something.

I saw really strange stuff with one bad SATA cable on my 6 drive ZFS array. It would work most of the time, but the scrub would either cough up CRC's or hang.

The machine is running a gigabyte motherboard (domestic gamer P35 board, similar to this http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2533, although it might be a DS4 variant). I've got 5 of the 6 sata ports wired to a 5 unit SATA hot swap bay (5 drives vertially mounted into 3 5-1/4 bays kind of thing). Now, because of the gmirror I can boot the system on any disk, or combination of plugged in disks. I should be able to succeed with the kernel probe up to the attempt to mount the root filesystem irrespective of any zfs pool, etc. And, indeed, this has been working fine for about two years. But, now it hangs in the same place no matter what disk I boot on (I've tried every bay). But, without ACPI enabled it does appear to boot ok... what's going on here? Is it possible that the machine has developed a hardware fault? Ok, finally, if I boot with ACPI disabled then one of the disks is missing. If I unplug it I get a disconnect message from the ata device, and a reconnect and reinit attempt when I plug it back in, but no device appears on the bus. Usually I can do a 'atacontrol detach sata4; sleep 1; atacontrol attach sata4' and the device reappears. This happens on the other buses, but not on the last one. It's not the disk, because if I swap it into another bay, it comes up and appears on the bus. On the other hand it doesn't appear to be that controller or slow in the drive bay because if I unplug all the over disks the system will boot that disk and get as far as the hang hmm. Is this a consequence of disabling the ACPI? Does anyone have a clue what might be going on?

Hi. Joe Karthauser wrote: I spoke too soon. It must have just randomly booted, because it is now hanging again. No amount of jiggling cables has made any difference. Can you provide verbose boot messages of your system from the beginning up to the problem? Especially, all related to the ATA. Do you have AHCI mode enabled in BIOS, or you using legacy ATA emulation? -- Alexander Motin ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
ZFS hanging at kernel boot now, but didn't before... (Re: ZFS MFC heads up)
Hmm, I've had a bit of a miserable afternoon trying to fight my RELENG_7 server, which now doesn't boot. :(. So, it's a ZRAID2 pool with a ufs/gmirror root partition split over 5 disks (gmirror on 500Mb partition on each of five disks, and zraid2 over the rest of each drive). What I did was to update the userland, and then reboot. I didn't upgrade the kernel (but I've subsequently done that and have the same problem). What happens is that the kernel hangs booting just after displaying a LABEL message or ZFS pool/spool message. I _can_ get it to boot if I boot single user with acpi switched off. When I do that I can manually start zfs, and mount all the partitions. However, one of the disks is missing more on that next.
