[Kernel-packages] [Bug 1484497] Re: [Wily] wakes up green drives without a valid reason
It's questionable if it should be considered a bug or not. The culprit
is smartd. Ironically I used the package smartmontools 6.3+svn4002-2 to
get smartctl, for testing if something wakes up a green drive. Despite
the policy to autostart everything by default, that can be autostarted
for better or worse, it's to consider if the default configuration, to
poll every 30 minutes, is a wise decision. By an EU Regulation all
external hard disk drives are forced to spin down and go to sleep after
a while. I disabled smartd.service, any unneeded service is unwanted on
my machine.
After disabling it, nothing does wake up a green drive anymore.
[root@moonstudio weremouse]# echo;date;t=10800;y=$(smartctl -A
/dev/sdc|grep Lo|awk '{print $NF}');sleep $t;x=$(smartctl -A
/dev/sdc|grep Lo|awk '{print $NF}');printf \n$(uname -rm)$(lsb_release
-d|cut -f2 -d:|cut -f1 -d()\n$x-$y=$((x-y)) spins in $(($t/60/60))

The only spin is caused by smartctl, when it was executed on demand, to
finish the test.
How I noticed that smartd is the culprit:

Hi,
a minimalist Wily server install, around 4.5 GiB small does cause
endless spin downs and spin ups, so that green drives get damaged. I
maintain an around 37.5 GiB large Arch Linux install, quasi using the
same software used by the Wily install and in addition a little bit
more software, which isn't used by the Wily install. For Arch Linux I
don't experience this issue. I expect the same for an Ubuntu install.
I'm already hunting the culprit, see
https://lists.ubuntu.com/archives/ubuntu-studio-devel/2015-August/006570.html
and
https://lists.ubuntu.com/archives/ubuntu-studio-devel/2015-August/006571.html,
but run out of ideas.
The claim the install is 2 GiB small is a typo, the backup archive is
of that size.
However, assumed Ubuntu won't contribute to
http://andrewmcconnell.photoshelter.com/gallery/GoLuiBLHIsmM this
feature should be removed from the defaults.

[Kernel-packages] [Bug 1484497] Re: [Wily] wakes up green drives without a valid reason
To rule out the kernel being the culprit, I build a kernel I'm using with Arch
Linux, were green drives stay asleep. IMO it's not caused by the package linux.
There are no differences for the config, that are relevant for the issue.
It's unlikely that there were any additional patches used for the Arch Linux
kernel, that are related to the issue.
The spin down/spin up test:
[root@moonstudio weremouse]# t=10800;y=$(smartctl -A /dev/sdc|grep
Lo|awk '{print $NF}');sleep $t;x=$(smartctl -A /dev/sdc|grep Lo|awk
'{print $NF}');printf \n$(uname -rm)$(lsb_release -d|cut -f2 -d:|cut
-f1 -d()\n$x-$y=$((x-y)) spins in $(($t/60/60)) hours\n
3.10.61-rt65-1-moonstudio x86_64Ubuntu Wily Werewolf
15342-15333=9 spins in 3 hours
Arch Linux only makes one spin, when smartctl wakes up the drive after 3
hours.
That's how I build the Ubuntu kernel:
[root@moonstudio src]# export CONCURRENCY_LEVEL=2;wget
https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.10.61.tar.gz
https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/older/patch-3.10.61-rt65.patch.gz
tar zxf linux-3.10.61.tar.gz
mv linux-3.10.61 linux-3.10.61-rt65
cd linux-3.10.61-rt65 gzip -dc ../patch-3.10.61-rt65.patch.gz | patch -p1
cp ../config-3.10.61-rt65-1-rt-lts.01.edit .config
make oldconfig make menuconfig make oldconfig
date
make-kpkg clean make-kpkg --initrd kernel-image kernel-headers
make-kpkg clean
date
Most likely the Arch kernel just had two additional patches:
change-default-console-loglevel.patch
fix-race-in-PRT-wait-for-completion-simple-wait-code_Nvidia-RT.patch
Both kernels are configured with CONFIG_X86_64=y and CONFIG_X86=y.
That's the diff of the Arch and Ubuntu config:

Thank you,
unfortunately it didn't fix the issue.

This issue never appeared related to kernel configs or kernel releases.
I suspect the culprit gets executed at startup.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
