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.

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.

this can't be the wanted behaviour for any removable storage devices?

Hi,
ipv4,
/etc/hosts
127.0.0.1 localhost
127.0.0.2 becherer1.site becherer1
195.167.0.5 becherer1.site becherer1
/etc/postfix/main.cf
myhostname = becherer1.site
inet_protocols = ipv4
on my older systems (opensuse 11.4) i can use:
programm "mailto"
and as address:
simon@becherer1
simon@localhost
simon(a)becherer1.site
simon
all will be delivered correct at the local machine.
if i use the simon@becherer1 or simon(a)becherer1.site or simon
the mail tells me in all cases: send to: simon(a)becherer1.site
if i use simon@localhost the mail tells me: send to: simon(a)localhost.site
i have the same settings like above in the same files in tumbleweed.
(because of newer system, there are much more settings in main.cf)
only send to "simon(a)becherer1.site" and "simon" will pass.
the simon@becherer1 will generate a "undelivered mail return to sender"
host or domain name not found
name service error for
name = becherer1 type=a: host not found
the simon@localhost will generate a "undelivered mail return to sender"
"simon@localhost loopbacks to myself."
sending a "ping" to becherer1 or becherer1.site will return
"from becherer1.site 127.0.0.2" and localhost will return "from localhost 127.0.0.1"
on both machnines identical, so normally the names are set correct?
i guess some other default for postfix may be changed, but i do not find
whats wrong, why did postfix not deliver the mails?
regards,
simoN

Hi,
I just upgraded my asus laptop with intel/nvidia graphics from 42.1 to
42.3, all went well so far.
But when entering
prime-select nvidia
I get: ERROR unable to query GPU information
The script runs anyway, I guess, because when I reboot at some point the
screen with the boot messages begins to flicker heavily (I could not
read the last message...). I had to restart and boot to runlevel 3, then
entered "prime-sectect intel" and now I can boot normally - but of
course only using the intel card.
I don't know which information you need to help me: please ask and I'll
try to provide it.
Thanks for your help!
Daniel

On the odd chance that I was ignored for possibly hijacking a thread,
I shall start a new one but copy and paste my comments in hope of an answer:
(re: Killing ReiserFS)
I have been following this thread with some interest because of having
been running ReiserFS since before he turned homicidal. I have had zero,
count that ZERO, problems in all that time so I read with some dismay
the effort to actively kill its usage in this whatever-you-call-it distro.
I think that the more relevant question to ask is not "can we keep this
file system around, pretty please" but "what distros are allowing its
use by not actively trying to kill it"? I have used opensuse since
before Mandrake went away, which has been a while and, although I don't
really want to change distros, I am not married to suse (or leap, or
whatever).
I feel that what we have here with opensuse/leap is an example of the
classic "swing" cartoon which shows the stages of project development
from sales, engineering, installation and what the customer actually
wanted. My need is not as complex as some and for that ReiserFS works
quite well.
So, my question remains, "If not suse/leap, then who"?
Hopefully someone will know what distros allow the freedom to use
whichever FS one wishes without running afoul of the FS nazis.
