PC locking up with input/output errors (SSD)

Sathors · 2014-04-01 13:49:50

Hi,

So since a few days, invariably after a little bit of time (generally around one hour), applications begin to be unresponsive, and I can glimpse in the terminal for example some input/output errors.

I tried looking at the journal using
journalctl -b -1
but I never do find any kind of error.

So I don't really know how to diagnosticate this problem.
I thought it could be the SSD failing, so I run an extended test using SMART. Everything seems fine.
I fscked all the partitions (ext4) forcing the verification, everything seems fine.

Do you have an idea of what could cause that ? Or why I can't find the corresponding errors in the journal ?

Thanks for your help,
Sathors

Would it be possible to post the error messages you are seeing in the terminal?

Sathors · 2014-04-01 20:27:22

Well this time it seems it hasn't lock up. But I have to copy down the log, because previous time there wasn't any way to get it after a reboot.

It seems all the problem begins like that :

# journalctl

And the lines since unhandled error code goes on and on all the time. All of this happened in less than 2 secs.
Now an ls gives me :

ls: reading directory .: Input/output error

I cannot use any function of my windows manager awesome, which gives me a
/usr/share/awesome/lib/awful/prompt.lua.53: input/output error
I can open an other terminal, but trying to run xterm at the prompt gives me :

bash: /usr/bin/xterm: Input/output error

Do you have any idea what could cause all of that ? Would it be the SSD faulty, even though it has less than one year and that the SMART extended test succeeds ?

Thanks for your input

I had this exact issue just before my SSD died (including it passing all the SMART tests).

It's worth testing with a different cable and SATA port in case one of them is faulty.

WonderWoofy · 2014-04-01 21:45:25

purely for my own curiosity... what kind of SSD is this?

Sathors · 2014-04-01 22:00:43

Well if it's going to die that's not exactly a good nows...

For your information, it's a 128go crucial m4.

Anybody that could confirm/infirm the nearing death ?
Thanks

Most SSDs have warranties from two to five years. So maybe your SSD is still within that range and might be able to be RMA'ed

Sathors · 2014-04-02 01:13:13

Then I'll begin cloning my partitions.

Are you aware of any mean of checking whether the ssd is really going to die ? Something more thorough or more specialized than SMART ?

Thanks

WonderWoofy · 2014-04-02 02:08:31

Sometimes the vendor has a special tool that can check for you, but I am not sure about Crucial/Micron.

When SMART works and indicates a drive going bad, it is a really great thing, but unfortunately it isn't accurate quite as often as one would expect.

Well well well.

I had done a backup of my home partition a few days ago (the problem had already started) on an external drive using rsync.
I did have some errors on a few unimportant files, saying me multibyte something.

Now when I want to access this backup (for example a 'du -sh backup'), or if I want to copy this backup to an other ssd using rsync, I get a lot of these errors :
rsync -a backup new_home

Buffer I/O error on device sdb1, logical block 1720889078
end_request:critical medium error, dev sdb, sector 172343908

(note : /dev/sdb1 is the backup drive)
and sometimes appears the error :

rsync: read errors mapping "backup/somefile": Input/Output error (5)

Also I cloned the root partition using dd if=/dev/sda of=/dev/sdc bs=1M comps=noerror,notrunc,sync, and it seems everything went fine without errors.
Do you think I'll still get Input/Output errors although dd didn't tell me nothing ?
Do you think it'll be better to copy using dd or clonezilla, or a filesystem-aware tool like rsync ?

Thanks for the help folks.
