ssd's self-test error log

Hello.

May it is better to output xselftest with -a option when selftest is not 
supported (like for all sandforce devices)?

Changing existing behavior may break scripts parsing smartctl -a output. 
Use newer option -x to enable all newer outputs.

Note that -l xerror may not work in many cases. It requires support for 
48-bit non-SMART ATA command READ LOG EXT in smartctl os_*.cpp layer and 
OS driver.

Bad block HOWTO for smartmontools

Hello,

thanks for your Bad block Howto for smartmontools under:

http://smartmontools.sourceforge.net/badblockhowto.html

It helped me understand the problems I had.

Since I use a software RAID5, your offered solutions did not quite work out, 
but I finally found a very elegant solution for Softraid:

echo repair > /sys/block/md1/md/sync_action

I am not sure, if this howto is still maintained. If yes, I think the mention 
of the above command could be of help for people with Softraid.

Best Regards

Patrick Zuther

smartctl fails on sat pass-through for version >=5.39.1

Dear smartmontools developers,

  we are experiencing a problem in accessing SMART information of SATA
disks attached to an Adaptec 5805 on Linux after the update to
smartmontools-5.41. With the previous version, smartmontools-5.39, we
had full access to SMART information and test.

On smartmontools-5.41, the following command, that is normally
successful with smartmontools-5.39, fails with "Operation not permitted"

[root <at> pc-tdq-sfo-12 ~]# smartctl  /dev/sg1 -d sat -a
smartctl 5.41 2011-06-09 r3365 [x86_64-linux-2.6.18-274.12.1.el5] (local
build)
Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net

Smartctl: Device Read Identity Failed: Operation not permitted

A mandatory SMART command failed: exiting. To continue, add one or more
'-T permissive' options.

After some bisecting, we realized the problem we experience was
introduced in release 5.39.1, by this change:

http://sourceforge.net/apps/trac/smartmontools/changeset/3052

My understanding is that ioctls on the scsi devices fails due to the
device being opened with the O_RDONLY flag:

[root <at> pc-tdq-sfo-12 ~]# strace smartctl  /dev/sg1 -d sat -a 2>&1 |grep

Problem enabling SMART on a drive in a CCISS RAID.

I have a system with an HP CCISS RAID with 6x36GB drives (an old one)
which has a drive that I can't enable SMART on. All the others are fine.

Attempting to enable SMART produces this:

# smartctl -s on -d cciss,3 /dev/cciss/c0d0

Informational Exceptions (SMART) disabled
Temperature warning enabled

I can still use smartctl to perform offline tests etc, but because SMART
is off, smartd won't monitor it or perform automatic tests.

Any clues?

smartctl values for Corsair Force Series GT (CSSD-F240GBGT) look really odd

Hello!

The device mentioned in the subject is a SSD device (controller:

ID9 looks odd to me. SSD_Life_Left is missing completely. And to be
honest, I'm not sure, if I should trust the other parameters and how to
interpret them. Especially Total_LBAs_Written, Media_Wearout_Indicator,
Raw_Read_Error_Rate, Hardware_ECC_Recovered, Soft_Read_Error_Rate and
Soft_ECC_Correction.

I ran two self tests (short and conveyance). Both didn't show any
problem / log entries.

I would be happy to get some more information about to interpret the
values.

Thank you,
kind regards,
Andreas

This device is likely not in smartctl database. This fact should be 
printed by smartctl -i.
http://sourceforge.net/apps/trac/smartmontools/wiki/FAQ#MyATAdriveisnotinthesmartctlsmartddatabase

In this case, smartctl uses default assignments for attributes which 
work for most HDDs. SMART attributes of SSDs differ considerably from 
HDDs (Note that there is NO standard for attribute format and assignments).

> ID9 looks odd to me.

SandForce Based devices use a very uncommon format for attribute 9: 
Hours and Milliseconds in high bytes:

161748468367395 = 0x931C00000023 = ~35 hours

>   SSD_Life_Left is missing completely.

It is attribute 231, also SandForce specific.
http://sourceforge.net/apps/trac/smartmontools/wiki/FAQ#TheSSD_Life_LeftAttributeofmynewSandForcebasedSSDreportszero

>

Please provide smartctl -i output also. We always need the exact ATA 
IDENTIFY string to add the device to the database. Please don't discard 
the first output line because it reports the smartctl version and platform.

Meantime you could use "-v 9,msec24hour32 -v 231,SSD_Life_Left" options 
to display the a mentioned attributes properly.

Thanks,
Christian

I already read it, but it doesn't solve my problem , because it
doesn't report zero - it doesn't exist at all.

-v 9 works fine, -v 231 doesn't work:

smartctl -a -v 231,SSD_Life_Left /dev/sda
