[Solved] Intermittent errors - Hard drive failing?

LeftyAce · 2018-06-27 04:32:32

Hi all,

I've recently received the following error (relating to my hard drive):

Waiting 10 seconds for f4017da9 ...
Waiting 10 seconds for 478ff45c ...

Eventually the waiting fails and I get dumped to an emergency shell. After two reboots everything was back to normal.

Then a day later, I managed to boot up all the way, only to have the / drive (SSD) but no /home (HDD). Again, reboot got things back to normal.

How can I test the HDD to see if it's failing? I ran the smartctl short test which completed without error, and I started the long test but can't tell if it's still running.

Thanks,
Lefty

smartctl -a /dev/sda

Could it be a loose connection? How are the drives wired?

The machine is a laptop (should have mentioned that), so the SSD is more of a card, the HDD is a regular laptop drive.

I managed to run the SMART full test and it passed. I'll open it up and make sure the HDD is well seated.

Please post the entire output - the table tells more about pot. problems than a single test.

Here's the output of systemctl -a /dev/sda:

That drive looks healthy.
Does this only happen on battery or also on external power supply?

Edit: and do you have a parallel windows installation?

I would look into this: '193 Load_Cycle_Count 0x0032 116 116 000 Old_age Always - 252690'.

The value of 252690 is a high number so you might want to do something to keep the drive from constantly parking its heads.

LeftyAce · 2018-07-01 15:49:31

No parallel windows installation.

My drive setup is a bit complicated:

/boot is on an external USB.
/ is on the internal SSD.
/home is split on the internal SSD and the internal HDD (using bcache, so the SSD partition is a 32GB cache for the HDD).

Both / and the bcache volume are encrypted using dmcrypt+luks.

R00kie, where should I start to investigate the large number of head parks? Is there some way to find out which process is spinning up the HDD? You're absolutely right that the HDD is parking and unparking frequently, I can hear it. Given the bcache setup, I'm surprised though, if most reads/writes are coming off the SSD, the HDD should just stay off.

LeftyAce · 2018-07-01 16:18:59

Thanks graysky.

I'm a bit confused. It looks like my disk shouldn't be spinning down at all:

# hdparm -B /dev/sdb

/dev/sdb:
 APM_level      = 128

The wiki says "Values from 1 to 127 permit spin-down, whereas values from 128 to 254 do not. "

R00KIE · 2018-07-01 20:46:56

I'm going to guess (because you deleted that part of the output of hdparm) that you have a western digital drive. For those you probably want to set the APM level to 254 or 255, whichever makes the drive stop parking and unparking the heads.

LeftyAce · 2018-07-01 21:35:07

Thanks R00KIE! I actually didn't delete any of the hdparm output, what I posted was all I got. But you're right, it's a WD HDD. I've set the hdparm value to 254 and so far the parking seems to have stopped.

Question: I'm using tlp (https://wiki.archlinux.org/index.php/TLP), and I can specify hdparm settings for both my drives. Is there any point in setting values for the SSD? Do they do anything?

seth · 2018-07-01 22:14:19

SSDs have no head to rest ;-)

On the original topic: try the "rootwait" or "rootdelay=30" (this will wait 30 seconds before attempting to mount root) parameters - the decryption probably takes too long. On a hunch, this could be related to the crng issue, https://bugs.archlinux.org/task/58355

LeftyAce · 2018-07-01 22:26:35

Thanks Seth. If this happens again (it hasn't happened since I first posted) I'll add the rootdelay term.

At this point I don't know if it's solved or not, but I'll mark it [solved] :-)
