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

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

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

SYSTEM: Intel 875WP1-E motherboard with SATA drives on motherboard's SATA ports
|
|
PROBLEM: smartd makes NTP time drift
|
|
REPORTER: nohez@cmie.com
|
|
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
|
|
NOTE: When using SATA disks, linux kernel k_smp-2.4.21-108 (SMP because
|
|
of hyper-threading) and xntp-4.1.1-177, the server time went
|
|
out of sync with system time. Problem goes away when SATA
|
|
disks removed.
|
|
|
|
|
|
SYSTEM: Dell servers using AACRAID (SCSI)
|
|
PROBLEM: Locked up, needed to be rebooted

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

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