SATA DMA errors on second ICH10 busI have four identical SATA300 disks on a Supermicro C2SEA which has 6 total
SATA ports on an ICH10. This is from 20090114 CURRENT sources with a custom kernel (no PREEMPTION, INVARIANTS, WITNESS, and many drivers removed, but otherwise same as GENERIC). The first two disks (ad6 ad7) seem to work fine, and I've done buildworld, zfs, and nfs tests on both of them together and separately. The second two disks (ad8 ad9) work okay for some things (labeling, zpool creation, gmirror creation, dd slice), but as soon as I start doing anything more complicated involving at least one of them (gmirror write access, cp to ufs partition, cp to zfs over nfs, etc.) I get the following errors on all involved disks (including the first two): Jan 15 17:35:07 lust kernel: ad8: FAILURE - load data Jan 15 17:35:07 lust kernel: ad8: setting up DMA failed Jan 15 17:35:07 lust kernel: ad8: FAILURE - load data Jan 15 17:35:07 lust kernel: ad8: setting up DMA failed Jan 15 17:35:07 lust kernel: g_vfs_done():ad8s1e[WRITE(offset=1881014272, length=131072)]error = 5 Jan 15 17:35:07 lust kernel: ad6: FAILURE - load data Jan 15 17:35:07 lust kernel: ad6: setting up DMA failed Jan 15 17:35:07 lust kernel: g_vfs_done():ad6s1e[READ(offset=4117364736, length=32768)]error = 5 Jan 15 17:35:07 lust kernel: vnode_pager_getpages: I/O read error Jan 15 17:35:07 lust kernel: vm_fault: pager read error, pid 985 (cp) This continues for a while and then with ufs panics pretty soon. With zfs it starts hanging most processes after awhile. (7.1 found the disks but failed to complete booting, freezing up right after probing. The only related issue I could find is kern/125859.) I'm happy to provide any information needed or try patches. I would also like to know if there's a way to turn off DMA on just these two disks (atacontrol mode won't seem to set anything but SATA300).

They do have the bad firmware (which I'll update and test again as soon as Seagate provides a working fix), but SMART reports no errors on any disk, and all self-tests past. Linux has been running on this machine for a while now under similar conditions with no errors at all. Also, there's a similar report with WD disks in ICH7.

Some people recommend to use different vendors for the components of disk mirrors, in order to reduce the likelihood that both drives will fail at about the same time due to a firmware bug or similar. That advice seems to be particularly valuable given the current firmware problems that particular Seagate disks are exhibiting. For example, I've got these in a server: # atacontrol list | grep ad Master: ad0 <SAMSUNG HD160JJ/WU100-41> Serial ATA II Master: ad1 <ST3160811AS/3.AAE> Serial ATA v1.0 # diskinfo ad0 ad1 ad0 512 160041885696 312581808 310101 16 63 ad1 512 160041885696 312581808 310101 16 63 # gmirror status Name Status Components mirror/gm0 COMPLETE ad0 ad1 Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.

I've confirmed with Seagate and others that the firmware these disks already have (CC1F) is not affected by the firmware problems. The instability (as described in kern/130726) continues with a kernel from today. I've traced it down to exclusively and reliably being caused by access to disks on multiple channels simultaneously (access to any pair of disks on the same channel works fine). If anyone has any suggestions or any other data I should collect let me know as I will have to put these machines into production shortly (without freebsd unfortunately). :-Dylan _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..." |

I suspect I see the same problem with some nvidia SATA controller. If there is high load on both channels of one controller, there are exactly the errors you showed. Your kernel does not use INVARIANTS, is this correct? Otherwise you should see a very specific panic caused by a KASSERT(). I analysed the problem a bit. You can see my findings in the thread "Question about panic in brelse()". I suspect a hardware bug plus incorrect error handling in the driver in FreeBSD. As a workaround, I suggest you connect each disk to a separate controller - if you have not more disks than controllers. _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..." |

As a workaround, I suggest you connect each disk to a separate > controller - if you have not more disks than controllers. When I do turn INVARIANTS on I ultimately get a number of different failures, depending on what sort of operation I'm doing. I think I've seen the brelse panic you mentioned but not recently. Here's one from today doing cp on ufs: ad0: FAILURE - load data ad0: setting up DMA failed g_vfs_done():ad0s1e[READ(offset=1843986432, length=65536)]error = 5 vnode_pager_getpages: I/O read error vm_fault: pager read error, pid 819 (cp) kernel trap 9 with interrupts disabled Fatal trap 9: general protection fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x8:0xffffffff802ae9fe stack pointer = 0x10:0xfffffffeb61bfae0 frame pointer = 0x10:0xfffffffeb61bfb00 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = resume, IOPL = 0 current process = 12 (irq14: ata0) lock order reversal: (Giant after non-sleepable) 1st 0xffffffff80628750 bio queue (bio queue) @ /usr/src/sys/geom/geom_io.c:68 2nd 0xffffffff8062b8c0 Giant (Giant) @ /usr/src/sys/dev/kbdmux/kbdmux.c:1044 KDB: stack backtrace: panic: mutex Giant not owned at /usr/src/sys/kern/tty_ttydisc.c:1127 cpuid = 0 I certainly agree that there's some problems in error handling, but I'm more concerned about the underlying problem causing the errors. :-Dylan _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..." |
