excessively high Load_Cycle_Count

hi!

just being curious since WD support seems so unresponsive with this - has anybody experienced abnormal
high load_cycle_count with his disk(s) ?

i wonder if this only happens on linux due to different buffer-flush-intervals, so i`d rather be
interested, if windows machines also suffer from this problem.

see discussion threads at :
http://marc.info/?l=linux-kernel&m=120777293511872&w=2

parking hdd heads more than 90000 in about 900hrs with a system/root disk looks scary to me, especially
because most specs tell that disks can "only" do <1.000.000 of those.

i`d like to get a clue if it`s up to the hardware manufacturer or to the OS guys to fix this and i`d be interested
in raising awareness.

btw, what about adding a feature to smartcl to divide load Load_Cycle_Count by Power_On_Hours and spit out
an additional message when resulting value is abnormally high ?

regards
roland

ps:
the only way to tune the parking interval for WD GreenPower drives is getting a proprietary tool from WD
support, btw.

reset SMART health status?

Hello,

I have an elderly Dell PE 2550 that I am using as a testbed platform. 
That is, it is used for experimenting with networking setups, sysadmin 
scripting, virtualization, and anything I want to play with that I need 
actual hardware for (and thus can't just use a VM). As a consequence, 
there is absolutely no mission critical data on this box and if I wreck 
the OS, I can just reinstall and start over.

It has two SCSI drives in it, and several months ago one of them began 
reporting SMART errors. The output of smartctl -a is at the end of this 
email.

Specifically, it looks to me like the disk found two bad blocks at that 
time but has not had any errors since, and two long background 
self-tests I ran just a few days ago found no errors.

The LED on the front of the drive is green and the long self test comes 
up clean, and since I have no valuable data on the drive it's 
essentially "good enough" for me right now. And since it's well out of 
warranty and SCSI ultra-320 disks are needlessly expensive these days I 
don't plan to replace it until it croaks for good -- which it shows no 
sign of doing anytime soon. However, I am getting tired of the constant 
notifications from smartd.

So my question is -- how can I "reset" that SMART health status? I have 
been reading man pages (sg3_utils, smartmontools, etc.) and SCSI mode 
page documents all morning with no luck. Basically I want to either 
change the "threshold" for the LOGICAL UNIT FAILURE PREDICTION to more 
than the two errors its found or, if that's not possible, just zero out

It seems your guess is right. After another 90 hours (now 180 hours total) 
work and 9 power cycles only the following values changes (despite of 
uptime, cyles or temperature of course):

Raw_Read_Error_Rate            7974 -> 91733
Seek_Error_Rate                 292 -> 1178
Load_Cycle_Count                328 -> 881
Hardware_ECC_Recovered           32 -> 185
Multi_Zone_Error_Rate         28037 -> 15088
Run_Out_Cancel         429509246925 -> 2628531060695

Would you say this is still ok? And do you want me anything to do (running 
special tools/sending in logs) in case you want to adapt smartmontools to 
this harddrives specific way of storing some values?

Thanks,
Marcel

Similar here with a new FUJITSU MHW2080AT Firmware 0000000B

  5 Reallocated_Sector_Ct   = 8589934592000 = 0x7D000000000

203 Run_Out_Cancel          = 1529008553543 = 0x1640002FE47

FreeBSD 7.0 hptrr

Hi list,

since FreeBSD 6.3/7.0 there is a native driver for HighPoint RocketRAID 
devices, is there a way to monitor the disks behind?
if not, is there a plan to implement this feature?

thanks
Thomas

Re: FreeBSD 7.0 hptrr

I personally do not own a motherboard or add-on card with a HighPoint RocketRAID chipset, so I won't be able
to develop or test any support for this.  However, I believe we are always open to patches, and additional developers.

Re: FreeBSD 7.0 hptrr

Hi,

i would help to make a patch, but i have few coding experience.
the hptrr driver has Scott Long portet to FreeBSD, is it possible that you ask him about this problem,
because i have no 
email and it is better when 2 Port Maintainer speak together, or can you give me a hint, where i can get some infos.

Smartd reporting failed disk test, but smartctl says smart is not supported

Hi,

the smartd of one of our cluster nodes reported a problem with it's
harddisk:

    May  9 15:53:09 compute-1-6 smartd[3501]: Device: /dev/sda, FAILED SMART self-check. BACK UP DATA NOW! 

A smartctl -a /dev/sda gives me a:

        smartctl version 5.33 [i686-redhat-linux-gnu] Copyright (C)
        2002-4 Bruce Allen
        Home page is http://smartmontools.sourceforge.net/

        Device: ATA      ST380815AS       Version: 3.AA
        Serial number:             5QZ0C8KW
        Device type: disk
        Local Time is: Fri May  9 16:03:14 2008 CEST
        Device does not support SMART
        Request Sense failed, [Input/output error]

        Error Counter logging not supported

        Error Events logging not supported

        [GLTSD (Global Logging Target Save Disable) set. Enable Save
        with '-S on']
        Device does not support Self Test logging

The harddisk does support smart. But anyways, how does smartd think it's
broken
if it can't be queried at all? Is this even possible?

BTW, smartctl give me that output on all my nodes with the same
configuration.
But these nodes do not complain about a mysteriously broken disk...

The disk is connected to a on-board Sil3114 SATA Controller (no raid) on
a
Tyan Thunder K8SD Pro (S2882-D). No Smart setting in BIOS. We're using a
Redhat derivate (CentOS4) with Linux kernel 2.6.9-67, loaded module is
sata_svw.

Can someone shed some light on this please?

Cheers
Arne
