Re: Interpreting smartctl data -

[Denis Leroy]

I had one batch of drives that needed a firmware update.  The drives 
were all in USB cases, but to apply the firmware updates using the 
vendor's utility I had to remove each drive from the USB case and 
install in an old PC.




Yes, that sounds familiar :-)

I did manage to update a couple of Seagates here through USB with 
hdparm, but it took a bit of trickery to figure out the right options 
and to extract the actual firmware binary file from the manufacturer 
downloadables.

The output looks good to me.


You should be able to run the long test, even through the USB interface. 
Good point about the firmware update, although a quick look on the web 
doesn't indicate an update is available. Many disk drives firmware can 
be updated from Linux with the hdparm tool (hdparm --fwdownload), 
although it may be easier to use the Windows or mac tools provided by 
the manufacturer, if you have those OSes available to you.

No cause for concern in this, but the USB interface isn't giving all 
the information.   I'd connect the drive with the
native interface (e.g., put it in a spare system) and run the long 
test.  Another concern is that the drive may have
some custom firmware.  See if you can download a data sheet -- drives 
manufactured to OEM specs for
a specific application seldom have data sheets -- and check for 
firmware updates on the vendor's support site.

Re: Interpreting smartctl data -

[Denis Leroy]

smartctl is your friend when it comes to evaluating a disk drive health. 
Keep in mind, though, that SMART is not fool proof. Some disk damage may 
not be caught by SMART, but if SMART says your drive is damaged, then it 
probably is.


First, check the overall health status ((replace /dev/sda with the 
approriate disk device in your case):


# smartctl -H /dev/sda

will give you a PASSED or FAILED test. Note that I've seen disks that 
make helicopter sounds and still have a PASSED status. This is not very 
accurate, but the attributes do give interesting values, like the power 
cycle count, or overall power on hours.


A much better overall indicator is the error log. A non-empty error log 
is a huge read flag:


# smartctl -l error /dev/sda

Finally, the best thing to do is to have the disk firmware run a 
self-test. There are two types: short (a few minutes) and long (maybe an 
hour). Run a short test first, then a long test if that passes, to be sure:


# smartctl -t short /dev/sda

Then monitor the result with

# smartctl -l selftest /dev/sda

To run the long test,

# smartctl -t long /dev/sda


Hope this helps.

I'm just trying to determine how much confidence I can have in it. It 
was interesting to see that it was formatted Linux XFS initially. I 
reworked it with gparted and ext4 to test it. Presently it is in a USB 
adapter connected to a USB2 port on this computer. It appears to have 
been running for 2.6+ years, I have a number of drives with at least 
that much time on them and they are still going.


Any thoughts on making sense of smrtctl are appreciated.

Thanks,

Bob

As hinted, the culprit appears to be lightdm. Switching to gdm fixes the 
problem.

Fedora 25 upgrade woes

[Denis Leroy]

Hi List,


So I updated both my Fedora laptops from 24 to 25, resulting in both 
booting into black screens with no login dialogs and no way of going 
into a console or looking at logs.



Both systems are very different. One is a Lenovo, built-in Intel 
graphics support and XFCE, the other is a Dell with a AMD Firepro M5100 
graphics card running Cinnamon. Yet the result is the same. I assumed 
Wayland is at fault here, however I noticed both systems work fine if I 
boot with an older kernel:



kernel-4.8.6-300.fc25.x86_64 : works

kernel-4.8.8-300.fc25.x86_64 : nope


I had some trouble finding further info on this looking at various 
forums and mailing lists, hence my message here. Any insight appreciated.

Sounds like a bad disk to me. Run some diagnostic with smartctl (from 
the smartmontools package). What does 'smartctl -H /dev/sda' return ? 
(replace sda by your disk name if it's different).

What's the content of the error log ? (smartctl -l error /dev/sda) A 
non-empty error log is a good sign the disk is on the down curve.

Next, run a quick self test (smartctl -t short /dev/sda), wait 2 minutes 
then check the result with "smartctl -l selftest".

If that succeeds, run a long test (smart -t long /dev/sda), which takes 
about 2 hours.

[F-13] Printing regression ?

[Denis Leroy]

Hi list,

Woke up this morning to find my printer no longer working. Looks like a 
recent F-13 testing update broke my setup, even though printing has been 
very very stable for me as a rule these past couple of years.

I'm seeing

/var/log/messages:Sep  8 08:26:54 jupiler hpcups[2108]: 
prnt/hpcups/HPCupsFilter.cpp 493: cupsRasterOpen failed, fd = 0


after trying to reconfigure the printer (an HP Photosmart C7280). 
Downgrading the recent ghostscript testing package didn't fix it. I'm 
still looking into it, but has anyone ran into similar problems ?
