6 | The following are reports of serious problems (eg system lockup) which | |
7 | were due to smartmontools. There are DARWIN, LINUX, FREEBSD, SOLARIS | |
8 | and WINDOWS sections below. | |

10 | ||
11 | LINUX | |
12 | ----- | |

14 | You may also wish to search the linux-kernel mailing list for problem | |
15 | reports concerning smartmontools. Here is the URL: | |

18 | SYSTEM: Any system with USB ports and USB storage devices | |
19 | PROBLEM: Using smartd/smartctl on USB "SCSI" storage devices can cause kernel hang | |
20 | REPORTER: see link below | |
21 | LINK: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=107615 | |
22 | NOTE: USB storage devices are handled as SCSI devices by the kernel. But many of these | |
23 | devices do not comply with SCSI specs, and can cause the kernel to hang. | |
24 | Avoid using smartd/smartctl on these devices (they don't do SMART anyway). | |
25 | In particular, the use of smartd DEVICESCAN in /etc/smartd.conf can cause | |
26 | these devices (typically represented by /dev/sda or /dev/sdb) to hang, and | |
27 | the kernel to lock up. | |
28 | FIXED: This problem should be fixed in smartmontools-5.25 and greater. | |

31 | SYSTEM: Intel 875WP1-E motherboard with SATA drives on motherboard's SATA ports | |
32 | PROBLEM: smartd makes NTP time drift | |
33 | REPORTER: nohez@cmie.com | |
34 | LINK: http://groups.google.de/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&selm=Pine.LNX.4.33.0310111545530.1047-100000%40venus.cmie.ernet.in.lucky.linux.kernel | |
35 | NOTE: When using SATA disks, linux kernel k_smp-2.4.21-108 (SMP because | |
36 | of hyper-threading) and xntp-4.1.1-177, the server time went | |
37 | out of sync with system time. Problem goes away when SATA | |
38 | disks removed. | |
39 | ||
40 | ||
41 | SYSTEM: Dell servers using AACRAID (SCSI) | |
42 | PROBLEM: Locked up, needed to be rebooted | |
43 | REPORTER: drew@eastvan.bc.ca | |

47 | SYSTEM: Box with Promise 20265 IDE-controller (pdc202xx-driver) and > 2.4.18 kernel with ide-taskfile support | |
48 | PROBLEM: Smartctl locks system solid when used on /dev/hd[ef]. | |
49 | REPORTER: Georg Acher <acher@in.tum.de> | |
50 | LINK: http://sourceforge.net/mailarchive/forum.php?thread_id=1457979&forum_id=12495 | |
51 | NOTE: Lockup doesn't happen with 2.4.18 kernel, and doesn't affect /dev/hd[a-d] | |
52 | This appears to be a problem with the pdc202xx-driver and has been reported | |
53 | to the pdcx maintainers. If you enable the Promise-BIOS (ATA100-BIOS) then | |
54 | everything will work fine. But if you disable it, then the machine will hang. | |
55 | ||
56 | ||
57 | SYSTEM: Box with Promise 20262 IDE-controller | |
58 | PROBLEM: Smartctl locks system solid | |
59 | REPORTER: Ben Low <ben@bdlow.net> | |
60 | LINK: http://sourceforge.net/mailarchive/message.php?msg_id=5074201 | |
61 | NOTE: Similar to previous report: Promise Ultra66 2-port card (20262) which, with | |
62 | linux 2.4.20, suffers from the lockups reported above. But it was | |
63 | impossible to enable the Promiste BIOS. A kernel patch is referenced | |
64 | to fix the problem. | |
65 | ||
66 | ||
67 | SYSTEM: Promise 20265 IDE-controller | |
68 | PROBLEM: Smartctl locks system solid when used on CDROM/DVD device | |
69 | REPORTER: see link below | |
70 | LINK: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=208964 | |
71 | NOTE: Problem seems to affect kernel 2.4.21 only. | |
72 | ||
73 | ||
74 | SYSTEM: Promise IDE-controllers and perhaps others also | |
75 | PROBLEM: System freezes under heavy load, perhaps when running SMART commands | |
76 | REPORTER: Mario 'BitKoenig' Holbe Mario.Holbe@RZ.TU-Ilmenau.DE | |
77 | LINK: http://groups.google.de/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=1wUXW-2FA-9%40gated-at.bofh.it | |
78 | NOTE: Before freezing, SYSLOG shows the following message(s) | |
79 | kernel: hdf: dma timer expiry: dma status == 0xXX | |
80 | where XX is two hexidecimal digits. This may be a kernel bug | |
81 | or an underlying hardware problem. It's not clear if | |
82 | smartmontools plays a role in provoking this problem. FINAL | |
83 | NOTE: Problem was COMPLETELY resolved by replacing the power | |
84 | supply. See URL above, entry on May 29, 2004 by Holbe. Other | |
85 | things to try are exchanging cables, and cleaning PCI slots. | |

107 | ||
108 | SYSTEM: Any system before Tiger | |
109 | PROBLEM: Can't switch off SMART, can't switch off auto-save, can't run | |
110 | short tests. | |
111 | REPORTER: Geoff Keating <geoffk@geoffk.org> | |
112 | NOTE: There's a bug in the system library: when you ask it to | |
113 | do any of these things, it does the inverse (switches on, | |
114 | runs extended tests). Radar 3727283. | |
115 | ||
116 | SYSTEM: All known systems | |
117 | PROBLEM: When drive is asleep, SMART commands fail | |
118 | REPORTER: Geoff Keating <geoffk@geoffk.org> | |
119 | NOTE: You can prevent the drive from sleeping by saying | |
120 | pmset -a disksleep 0 | |
121 | or by unchecking the 'Put the hard disk(s) to sleep when possible' | |
122 | checkbox in the Energy Saver preferences. Radar 4094403. |
