SMART statistics for 40, 000 disk drives, from Backblaze

Dear Smartmontools developers and users,

The company Backblaze has 100 Petabytes of data stored on 40,000 disk drives.  They have released some
interesting statistics showing how SMART data correlates to drive failure, which may be of interest to
some of you.  A good entry point is: https://www.backblaze.com/blog/hard-drive-smart-stats/ .

Cheers,
	Bruce

kernel errors and unknown SMART properties

Hi!
My issue is a bit complex. Please bear with me.
I wrote a lenghty article on the subject a year ago:
http://yalis.fr/cms/index.php/post/2013/12/14/“If-it-ain’t-broken,-don’t-fix-it”…-or-should-you

At the time, I decided to just let things be, since I had no clue to a 
solution.
Today, I decided to try some new tests. I ran smartctl with -d marvell, 
ata, scsi, sat, sat,12, sat,16, with -i, -a, -x, diff'ed the results… 
all the time while running tail -f /var/log/syslog | grep kernel.

First, I could see that probably ALL of my kernel errors stem from Smart 
actions.

But all these tests produced loads of Unknown_Attribute. _Until I ran_:
diff <(smartctl -d sat,12 -x /dev/sda) <(smartctl -d sat,16 -x /dev/sda)

And there, for the first time in a very long time, I could see:
>   1 Raw_Read_Error_Rate     POSR-K   200   200   ---    -    0
>   3 Spin_Up_Time            POS--K   229   176   ---    -    3533

smartd's email notifcations

Hi,

configuring email notifications of smartd is a pretty unpleasant
experience, I have to say. I'm still not sure that I've got it right,
and I'm not even sure whether smartd supports what I want.

In smartd, I currently have
-m root -M daily -H -t -l error -l selftest -R 5! -R 187! -W 2,45,50

And smartd is started with -s /var/lib/smartd to make the states
persistent across reboots and restarts of smartd.
(BTW: State persistence makes so much sense to me that it should be
enabled by default, IMHO.)

Do I have to specify -U 198 to get emails about offline sectors? The
documentation claims that -U 198 is the default. So I hope I'll get emails.

In addition, I want to get an email whenever the reallocated sector
counter increases (that's why I have -R 5!). But until recently, I
didn't have -M daily in smartd.conf and -M once was the default,
apparently. So I got exactly one email from smartd saying the counter
increased. I never got a second or even a third email, even though the
counter continued to increase.

So I added -M daily, but the documentation says that -M daily means that
I get daily reminder emails. My interpretation is that once the
reallocation sector count has increased, I get one mail per day forever
- even if it does not increase further. That would be less than ideal,
to be honest.

Re: Beginner Help

Doesn't which drive you were testing in the command line tell you where it's plugged in?

i.e. smartctl -a /dev/sda [Well, *you* asked it to list all the information for /dev/sda - so it should be obvious that whatever drive is plugged into /dev/sda is the drive you're referencing!]

If you tested /dev/sda - then the result is for the drive that is connected to whatever port is /dev/sda!
If you move that drive to another port, it's going to be /dev/sdb or something different. But the device *you* supply to test is which port the drive is plugged into. You're not testing a specific device/drive, you're testing the device connected to a specific port. [/dev/sda in the example above.]

Further, if you look at the output, it will list the serial number of the drive. If you're really not sure, you can compare the serial number of the output with that physically printed on the drive.

As I noted in my initial response to the list, it really seems you haven't thoroughly read the docs and spent substantial time understanding the very basics of the tool - so you ask very odd questions. Perhaps I'm overly irritated about it, but it seems, to me at least, like you're wasting time asking for others to solve your problem and supply an exact command-line example that will do everything you need. [Like logging, for example. "> somefile" seemed obvious ...]

The same criticism applies to this "position" question. Smartmon doesn't *continually* monitor the state of specific controller ports or drives. It gives you some stats that apply to the very instant that smartmontools ran on a particular/specific device. If the drive/device experiences problems [or is unplugged etc] 5m from now, smartmontools won't know anything about it until you run it again. It will then, again, give you some values on the drive that apply to that specific moment in time, and that will apply to the device you asked it about - i.e. /dev/sda.

-Greg

Hi Robert,

By disk position I mean to say that suppose you have multiple disks in your machine then say disk at position 2 was plugged in or out, disk at position 4 had a bad sector etc. I mean to say each disk would be placed at a position in your machine, so can we get this position using smartctl.

One thing more that how smartd is useful to us?

Thanks & Regards,
Manu

Do keep in mind 5.38 is quite old. I recommend you upgrade. Beyond that,
it is -x, not -X (Linux is case sensitive). The old version of the -x
command is -a . -x requires the drive support 48 bit commands, while -a
only requires 28 (I think). However, on larger drives, the 28 bit commands
can return bogus values.

For the individual pieces of info:

1 - Position of the drive - Don't understand what you want here. The age
of the drive???
2 - Disk plugged in or out - In Linux, the system logs should record that.
SMART has nothing to do with that.
3 - Bad sector - Look for changes (in SMART) in the *RAW* values of
pending and reallocated sectors. Of course, not pending sectors are really
bad, but a change in the value will tell you something is going on, at
least for platter drives. SSD drives are still to new to me to give firm
advice.

smartd ATTRIBUTES question

Here is my smart.conf file:

 

# This is the configuration file for smartd.   It is automatically generated by

# the script /usr/TKLC/plat/sbin/smartCreateConfig, which gets called any time

# 'syscheck --reconfig' is called.

#

# Here's a brief description of what the command line means:

# -d: Specifies the type of devices (ata, scsi, 3ware, etc). This is only

#     required when a 3ware controller is present.

# -S on: Enable Attribute auto save

# -o off: Disable automatic offline testing

# -H: Check the SMART health status of the drive. If health fails, it's very BAD!

# -l error: Monitor the smart error log and report any new failures

# -l selftest: Monitor the smart selftest log and report any new failures

# Note: -f is intentionally not used.  This is due to concern over

#                          false positive failures as the disks age.

# '-m <nomailer> -M test -M exec /usr/TKLC/plat/sbin/smartd_logger' -

#       call smartd_logger if there are failures and once on initial startup.

# See the man page for smartd.conf for more details concerning the flags set here.

#

/dev/sda  -S on -o off -H -l error -l selftest -m <nomailer> -M test -M exec /usr/TKLC/plat/sbin/smartd_logger

/dev/sdb  -S on -o off -H -l error -l selftest -m <nomailer> -M test -M exec /usr/TKLC/plat/sbin/smartd_logger

~

Smartd man pages has a lower case “s”.

 

   -s PREFIX, --savestates=PREFIX

              [ATA only]  Reads/writes  smartd  state  information  from/to  files  ´PREFIX´´MODEL-SERIAL.ata.state´.  This  preserves  SMART

              attributes,  drive  min and max temperatures (-W directive), info about last sent warning email (-m directive), and the time of

              next check of the self-test REGEXP (-s directive) across boot cycles.

 

              MODEL and SERIAL are build from drive identify information, invalid characters are replaced by underline.

 

              If the PREFIX has the form ´/path/dir/´ (e.g. ´/var/lib/smartd/´), then files ´MODEL-SERIAL.ata.state´ are created in directory

              ´/path/dir´.   If  the PREFIX has the form ´/path/name´ (e.g. ´/var/lib/misc/smartd-´), then files 'nameMODEL-SERIAL.ata.state'

              are created in directory '/path/'.  The path must be absolute, except if debug mode is enabled.

 

              The state information files are read on smartd startup. The files are always (re)written after reading the configuration  file,

              before  rereading  the configuration file (SIGHUP), before smartd shutdown, and after a check forced by SIGUSR1. After a normal

              check cycle, a file is only rewritten if an important change (which usually results in a SYSLOG output) occurred.

 

Q1. Is “s” same as “S” in this case? I am trying to find out is we save attributes in the smartd logfiles via our “-S on” option.

 

Q2. In our smartd Test.pm code, we look in the logfiles for the field “SMARTD_FAILTYPE” for  smartd “Errors”. Are these the same as attributes. Will we see changes in ATTRBIUTES given the “-S on” option used in smartd.conf? I am just not sure if smartd “errors” means the same thing as smartd “attributes”?

 

Thanks,


Dan

Since it's a CF card, it is likely that the chipset of the card (or card
reader) does not support SAT. SMART is technically optional...

Re: Beginner Help

Well, one quick and dirty way would be to write a script that runs some of
the smartctl commands and dumps their [text] output to a file. That file
can be parsed to find what you want. Lots of scripting work, yes, but it
is possible.

Quick dump example:

smartctl -x /dev/sda > sda.log

Parsing the output is an exercise I'll leave to you.

Beginner Help

Hi,


I want to take the detailed logs of all the disk drives. For this what command shall I use?

Also, what command shall I use to find the position of the drive?

Also, what command shall I use to find the Event of the drive? Meaning event could be bad sector etc.


Thanks & Regards,
Manu
