Hi list,
speaking about software raid, not hardware controller based.
I am trying to go for some local OpenSuse machine and adding some
storage to it. Was considering Raid6, and now reading about a bit and
people left and right scaremongering about the larger the disks these
days in the double digit terabyte capacities even, the more likely it
is that during a reconstruction of a raid subsequent errors would
occur.
I would absolutely like to keep my data consistent, and I am not
thinking about double digit terabytes either, would stick to 2TB or
4TB disks, with Raid6 thats at least 4 physical drives.
Now I am wondering if it possible to use a good robust file system
that can add some more parity or check blocks or redundancy on top of
the hardware disks, to absolutely be able to always read my data.
I can't add multiple machines or like those high availability stuff
like clusters and what not I read about DRBD (Distributed Replicated
Block Device), or maybe I am just too scared by those technical terms
or consider myself to be just a simpleton and wanting to keep it
rather simple.
My use case here is also not constant availablity, when a disk needs
to be replaced, so be it, but I don't want to lose my data that I can
not ever read certain parts of it again or such stuff.
The thing that came to my mind was, if there is some file systems that
would add redundancy and robustness onto the mdraid system of the
linux kernel?
Anyone with some useful insights? Roughly speaking, I was considering
some simple pcie esata interfaced controller card and an external case
enclosure with esata port and portmulitplier stuff inside, that can
present at least 4 physical disks as JBOD, just a bunch of disks, so
that the Linux can seem them all separately.
Speed and rebuild times are not my concern, but data persistence and
data integrity. Not even number of physical disks, I could live with
even one of those 8 bay device enclosures and cases that are out there
on the market.
Thanks for any help and hints.

Hi,
I have one disk that is giving me problems with the smartd daemon. I get

The disk is indeed smart capable and it works fine, as long as I call

Just been emailed this link:
https://unix.stackexchange.com/questions/49650/how-to-get-keycodes-for-xmod…
To quote this article:
Here you can see keycode 97 is unused on my system:
|keycode 94 = less greater less greater bar brokenbar keycode 95 = F11
XF86Switch_VT_11 F11 XF86Switch_VT_11 keycode 96 = F12 XF86Switch_VT_12
F12 XF86Switch_VT_12 keycode 97 = keycode 98 = Katakana NoSymbol
Katakana keycode 99 = Hiragana NoSymbol Hiragana |
The keycode X uses and the keycode the kernel uses are OFF BY 8 for
"historical reasons". So take 97 - 8 = 89 and use 89 with the
setkeycodes command (again as root):
So to make my vol - button work (xmodmap keycode 122 -8 = 114)
setkeycodes e01e 114
This has worked! I have re-mapped apl the buttons apart from my hotkeys.

Still looking for the keycodes for F13-16

All,
I bought a used iSCSI based Drobo in 2016 with 50TB in it. It works
great, but it isn't fast by today's standards. (100 MB/sec absolute
max). And I never got it to work from openSUSE (Windows and Mac did
work).
I now need to buy something similar, but with fast I/O and Linux
support: 10 Gbit Ethernet and fibre-channel may be my only options?
Or are there point-to-point SAS external racks I should consider?
Also, I will likely want to put a SSD based cache in the mix at some
point. It could be integrated into the storage subsystem, or I could
use something like bcache and have the SSD be in the server,. It just
needs to be reliable and fast.
Recommendations? (I'm thinking used and $10K at the high-end for the
subsystem including PCIx cards and switches, if needed.)
== details
I need to buy a server with 50TB usable disk for a production
environment. A high speed disk subsystem is critical. And the project
may scale up over time.
It doesn't need to be a fail-over cluster, just a single server. I'm
looking at used equipment most likely.
I was thinking one with 4 CPU sockets would let me start with 2 CPUs
and then expand to 4 later on. Lots of RAM capacity would also be
great.
My first thought was to get a Dell R920 and throw a bunch of disks in it.
https://goo.gl/images/x3Rfj2
24 disk slots!
But then I looked at what size drives are available for those slots:
2.5 inch. I only see 2TB drives max.
I'm hoping to use a Dell server because it's the preferred brand at my
(new) job. Unless I'm missing something a standalone rack mount Dell
won't work.
So, now I'm looking at a used R820 most likely and some sort of disk
subsystem to support it. I picked it because it is only a 5-year old
design and it has 4 CPU sockets I can expand into as the server demand
increases over time. Also 3TB max ram is way above what this will
require, even long term.
https://media.adn.de/media/DE/DocLib/Poweredge_Easy_Matrix.pdf
A used, barebones R820 can be had for under $2K. Just add CPUs and ram.

I have mounted a Windows 10 share on openSUSE 42.3. On the Linux side,
all existing files are not shown. They exist on the Windows server,
but they are not seen on the Linux side. They are accessible. But they
do not show up in a directory listing. There is a description of what
I think is going on here:
https://www.spinics.net/lists/linux-cifs/msg14405.html
I realize that 42.3 is long in the tooth. But I have no choice but to
use it in the system of interest. Anyone know if this has been fixed
in openSUSE? And if so, when and where?

Hi,
1) what is for a new plain tumbleweed the correct priority for the displaymanagers?
with other words: what is the default displaymananger for opensuse-tumbleweed-kde
2) in what file is this stored?
i have on some tumbleweed (only updated from tumbleweed to tumbleweed):
yast-alternatives (never touched this settings any time before):
default-displaymanager ............. (auto):
select priority
/usr/lib/X11/displaymanagers/console 5
/usr/lib/X11/displaymanagers/lightdm 35 ????????????
/usr/lib/X11/displaymanagers/ssdm 25
/usr/lib/X11/displaymanagers/xdm 10
and on the other tumbleweed (updated from older opensuse versions to tumbleweed):
select priority
/usr/lib/X11/displaymanagers/console 5
/usr/lib/X11/displaymanagers/kdm 15
/usr/lib/X11/displaymanagers/lightdm 15
/usr/lib/X11/displaymanagers/ssdm 25
/usr/lib/X11/displaymanagers/xdm 10
i would like to set it to the "standard" for plain tumbleweed, so would be nice to know what it is.

I am working on setting up a new API in python, and part of getting it
set up is that I need to authenticate using chrome and selenium. Here is
a section of the authentication program that I am running into a
headache with:
options = webdriver.ChromeOptions()
options.binary_location =
"/Applications/Chrome.app/Contents/MacOS/Google Chrome"
chrome_driver_binary = "/usr/lib64/chromium/chromedriver"
driver = webdriver.Chrome(chrome_driver_binary, chrome_options=options)
This was originally written for a Mac OS, so I had to change the
directory for the chromedriver binary to the correct location on my
machine.
However, I don't really know what to put for the equivalent of where to
look for chrome options. Having never used selenium before or what it is
really all about, I don't even really know what chrome options are, and
I am hoping this is just a minor point to get past the authentication
portion of the api. I don't plan on using selenium for any further
development of the api, but it seems that I have to for this small
portion of what I am working on.
Anyone have an idea of what I need to do about setting the location for
Chrome options here in openSUSE tumbleweed?

Problem with Steam on openSUSE 42.3, running with Plasma on an Intel NUC
5th generation with Intel HD Graphics 5500 (Broadwell GT2). This is the
standard Steam package from the 42.3 OSS repo.
Rather annoying occurrence on somebody else's machine. I bought them a
game and installed Steam for the first time (not something I was ever
familiar with before) when last visiting back in August. I'm there again
now but only until tomorrow, probably many months until my next visit,
and they've just told me that the game stopped working some time ago. I
apply standard system updates via SSH but despite my pleas to always
advise me as soon as there's any problem, they didn't, so I've no idea
which of the hundreds of updates could have been responsible.
When launching Steam, I get the initial window and splash with sound and
animation, after which the message 'connecting to Steam account
[username]'. And then nothing, it hangs. If I click somewhere in the
window I get a sound effect but there's no visuals aside from the blue
background.
I need a quick fix as I only have a few hours before returning abroad.
Any ideas?
