Ubuntu 18.04.2 unresponsive on hd activity

nibbli
Hello,
When stuff is written to hd, my Ubuntu 18.04.2 gets kind of unresponsive.

To reproduce:
echo /dev/zero > test

Then click the Google Chrome icon (or anything else) on the left. The program doesn’t start 
until CTRL+C on aforementioned command. The disk is a mini PCI SSD. Changing the scheduler on the disk to “noop” doesn't help. It is a laptop Dell Precision M4600 with chipset Mobile Intel QM67 Express. Can anyone reproduce this? Regards

Please keep me in CC

It should return from that command immediately.  If you run
tail -f /var/log/syslog
in one terminal, then the echo in another do you see anything interesting?

are you sure you dont mean "cat /dev/zero >test" ? 

the above would just echo the string "/dev/zero"
into the file "test" ;)

It's even more worse that writing 9 chars (instead of tons of zeros)
requires "CTRL+C" before any other program could start. Using the
slowest HDD ever, let alone a SSD, it should be impossible to push
"CTRL+C" before writing 9 chars finished. If the OP is able to run the
echo line and to stop it using "CTRL+C" before it finished, something is
really fishy.

PS: The path could also be important. I tend to write test files
to tmpfs, IOW to RAM instead of a hard disk or a solid-state drive.

Yes, I meant cat instead of echo and I’m writing to my home directory.

I'm pretty sure that was just a typo although for a total freeze - vs "king od unresponsive"-
I have seen something similar.
I have seen the screen freeze until I hit the control key alone
on my old Ubuntu on a Dell Latitutde. It does however appear to
be the screen freezing except IIRC for the cursor responding to the mouse.
Hitting ctrl allows the backlogged clicks to execute. So, there may be something
to a quirky command - I keep suspecting the browse in my case but
just a hunch.

Running 'Beaver off of a USB stick has worked well for me but the whole thing
can hang waiting for VM  ( also on SSD). When the browser ( Chromium in optimize_for_size )
starts opening ad subframes all my memory gets depleted until i can kill them and the whole
thing hangs. It can take minutes for the task manger to respond....

Although I'm curious if this is just slow where the bottlebeck is.

Re: Ubuntu 18.04.2 unresponsive on hd activity

ubuntu-users mailing list
The OP does use 18.04. I'm an Arch Linux user, a rolling release close
to upstream and just in case I hold in reserve an Ubuntu 16.04 long term
support. However, to make backups of my Arch Linux and Ubuntu install
I'm using one and the other live media. At the moment I tend to go with
Xubuntu 18.10. Apart from two minor hickups, one related to screen
locking and the other related to an archiver GUI (I'm anyway a command
line guy), I didn't notice any issue. I'm just not upgrading 16.04
because roxterm was dropped. Actually roxterm was dropped by upstream,
so Ubuntu maintainers had a valid reason to discontinue packaging. In
the meantime upstream started to continue roxterm. I can't imagine a
live without roxterm :D and I dislike to make my own roxterm package.
To make a long story short, if 18.04 fails in such an odd way, I
recommend to use 18.10 for testing purpose and if necessary to
downgrade to 16.04, which is supported until 2021. However, I agree
that debugging the issue is important.

Actually I had the issue on 18.10, so I installed 18.04 and have the same issue there.

Ok,

If I run

  [rocketmouse@archlinux ~]$ strace google-chrome-stable

on my Arch Linux install, where I do not suffer from the issue you
experience with Ubuntu 18.10 and Ubuntu 18.04, I get tons of output I
do not understand. However, as already pointed out, if something goes
seriously wrong the output of strace tends to jump out at you. The
German term is "ins Gesicht springen", my English is broken, but if
there should be something in-between the output of starce leading to an
issue, it usually tends to jump into your face as an alien from the
movie "Alien" does.

No, nothing happens in syslog. BTW this also happens on regular disc activity. That’s how I discovered it because the becomes unresponsive sometimes and then came up with this artificial test.

Does the GUI app Disks show any problems?  Or if you haven't got a GUI
the command smartctl.

Hi Nibbli,

In my experience, really slow HDD performance is an early indicator of drive failure. I'd back everything important up and look into the smart status for any errors. If there is anything there the drive might need replacing.

If not that then I'd be looking at other bottlenecks such as swapping.

Regards,
Jared

I havent had time to follow this thread closely, but I recently had an
Adata SSD fail after running a couple months. Now, when I connect it as
a second disk to any PC, the machine freezes or has long pauses when I
try to access it.

bad ssd?
