looks like it's ever been anywhere near any error threshold is ID# 11,

 I ran the short test on the problem drives, and it said everything

 I'll try the long test at a later date.

Only your ad3.txt referred to below shows a (short) test having been
completed and logged.  You might check the smartctl -a results after
running at least short tests initially (looks like the long ones will
take 4-5 hours for your 4 drives) as Chuck has since suggested.

I'm not sure of the degree of logging you're having smartd use here, but
these small changes of value, especially up and down by 1 but a long way
from any error threshold, seem to be excessive and relatively trivial
perhaps debug-level detail?, ie most likely nothing of any concern.

I suggest reading man smartctl under '-A, --attributes' and then you'll
know as much as I do about what these may mean, and maybe worry less ..

  Here are all the smartctl -a outputs:

  http://l-i-e.com/ad1.txt
  http://l-i-e.com/ad2.txt
  http://l-i-e.com/ad3.txt
  
  ad3 is giving the most errors...
  ad1 gives a fair amount though

Do you mean according to that fine-detail attribute changes logging?  Or
real read/write/seek etc errors being logged to messages?

  And the ad0 and ad2 seem to be giving the spinup errors.

None of those reports seem to indicate any problems really, though if
anyone else cares to peek and notices any anomalies, I'm all eyes.

As for temperatures, the readings for all 4 drives seem very cool, but
then it is winter over there .. Temperature Celcius for ad0 to ad3 being
36, 27, 22 and 18 degrees C, each present and worst value well clear of
error thresholds .. did you interprete those values as temperatures?

  All the drives are kind of in an old PC tower (XT? AT???), except the

Might be worth checking that your power supply is up to handling 4 big

  ad2 and ad3 are in one of these Thermaltake iCage things:

These too were running nice and cool, 22 and 18C, when reported.  Cf my

rather more recent than your 5.33 freebsd6.0) this afternoon:

You're not seeing any reallocated sectors and you're not seeing UDMA errors 
(ie, in the cabling).  For lack of any better guesses, I'd gather that your 
drives are running above normal temps and aren't reading data perfectly, but 
are doing well enough that the built-in ECC is managing to deal with the issues.



I don't think it's 100C+ hot, as that's boiling -- but perhaps the

On a good day, the thermometers actually provide a real, calibrated, accurate 
result...but many drives don't even come close.

You should actually run smartctl -t long /dev/ad0 and repeat for all of the 
devices, and then re-check the smartctl -a output.  Might be better not to 
run the self-tests all at once, come to think of it.

  #1. The drive temperatures seem ridiculously high to this naive

  110 to 190 Celcius?  Yikes...  Or maybe that's normal?
  How hot is too hot?

As [EMAIL PROTECTED] pointed out, 100C is too hot.  I don't believe
those 110 to 190 numbers at all and suspect a drive would melt down at
anything near that.  Maybe these are Farenheit temperatures?

While perryh's advice about airflow and enclosures etc was spot on, I
suspect you need to check whether your particular drives may need some
corrective parameters if not fully covered by the smartctl database, as
some tend to do.  There are hints about this in smartctl(8) -v option.

  #2. Sequences like this show up a fair amount:
  Device: /dev/ad2, SMART Prefailure Attribute: 3 Spin_Up_Time changed
  from 152 to 153
  Device: /dev/ad2, SMART Prefailure Attribute: 3 Spin_Up_Time changed
  from 153 to 152
  Device: /dev/ad0, SMART Prefailure Attribute: 8 Seek_Time_Performance
  changed from 251 to 250

It'd be more useful to see these within the context shown by smartctl -a

  So is the real problem just that the drives are spun down and can't
  spin up fast enough? I can probably live with the consequences of
  that, and just go on with life -- The occasional HTTP request for an
  audio file will fail the first time, and they have to hit reload.
  
  This box is the fail-safe roll-over server for audio files that are
  all up online somewhere else managed by a professional (not me), so
  it's no surprise that the rare time-out on the real server also ends
  up with a drive spin up and failed request on the backup.  Kind of
  annoying, I guess, to an end user, but forcing the drives to always be
  spinning is probably not a Good Idea.

I don't know about that; while I wouldn't worry too much about spin-up
times unless it's a major annoyance to clients, I've always subscribed
to drives lasting much longer if left spinning.  The server delivering
this mail has spun its old IBM DTLA-something drive 24h/365d for nearly
9 years now, despite no aircon in a hot climate (up to ~45C in summer).

  Oh, here's a rather long excerpt of the log in case there's minutae
  within it that I've failed to include:
  http://l-i-e.com/smartd.log

The output of smartctl -a for one or two of your drives would likely be

 How hot is too hot?

I'd think if you can't hold onto them with bare hands they are too
hot.  100C is *way* too hot.  It's a wonder they are working at all.

If they are in an enclosure, clean the air filter (if any), make
sure the fan(s) is/are running (and actually moving air); add a fan
if there isn't one.  If they are not in an enclosure, (or if they're
in a big one, like the same box with the rest of the system) add a
fan either blowing on them or drawing air over them.

READ_DMA48 error interpretation

2007-01-16 Thread Richard Lynch
I know the messages below mean the hard drive or IDE cards are having
problems.

But is this like RED ALERT or more like YELLOW or what?

And what do I do about it?

umount and fsck everything a lot?

swap cards/drives around until it stops?

Ignore it and pray?

All the content is already copied to a second box, plus on CD, and
none of it is crucial data, so if I lose a LITTLE data by ignoring
this, I'm okay.

If the whole thing wipes out, that would be bad.

These drives are often spun down, as they are not accessed very often
-- it's the roll-over fall-back audio server in a cobbled-together
system I won't describe, as you'll just laugh at me. :-)  Is it
possible that these are just from the drives spinning up too slowly?

I know the messages below mean the hard drive or IDE cards are having

If you have current backups, it's a yellow alert.  Otherwise...


And what do I do about it?

umount and fsck everything a lot?
swap cards/drives around until it stops?
Ignore it and pray?


Try installing the sysutils/smartmontools port and run a drive self- 
test.  That will give you a much better assessment of the state of  
the drive and whether it is likely to completely fail in the next 24  
hours...
