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
this in the log:

The disk is indeed smart capable and it works fine, as long as I call
smartctl with "-d sat,16", which I do:

Having seen a few posts here and elsewhere of late from satisfied Linux
users of Brother printers, after using HP for the last 15 years and my
current one dying a death only partly brought on by my fist, I decided
this week to buy a Brother DCP-J572DW.
I've unboxed it, done the initial standalone setup and selected my wifi
network. Now I need to install the drivers that I've downloaded from
Brother's website but Jesus pancakes, it wants to pull in a lot of
32-bit crap.
In addition to the four rpms, Brother also provide a setup script.
Before going through this I thought I'd just do a search to see if
others have done it this way or some other way. Mistake. Now I'm just
overloaded with possibles. On the openSUSE subreddit, some posts suggest
this script stalls looking for the libusb-0.1-4 package. One user
suggests it's seeking the 32-bit version of that too, and another user
reports success after installing that. There's also the suggestion any
user might need to be added to the lp group.
Other posts suggest ignoring the script and using zypper/yast to install
the rpms. Here's the list of packages set to be installed:
https://susepaste.org/55221c2c
I know it's only a bunch of files that use a relatively small amount of
disk space, but having a spanking new PC running a fresh Leap install
and a spanking new printer, I didn't want my software selection to be
dragged back a decade. Have any other users here had success setting up
full print/scan functions without installing all these dependencies, on
a similar Brother inkjet?
Brother's website also mentions needing to open the following ports:
incoming UDP Port 54925
outgoing TCP Port 54921
but a lot of the references are to versions of openSUSE 10.x or 11.x. It
all seems very out-of-date and might it be different now with firewalld?

A short while ago I saw Firefox on a Windows machine and was most
impressed by seeing the pages BLACK with text and pix from websites
displayed in their proper colours (ie as they normally appear on a
"normal" FF with its all white background colour).
Well, if you prefer not to have your eyes staring at a white background
all the time then you can (in the Tools>Addons) the theme called DARK
READER.
Also, the same applies to Thunderbird -- you can have the same black
background to look at which is more comfortable on the eyes. The theme
fo TB is called DEEP DARK.
FYI.

In my notes I saved this message from the past. The suggestion gets the
broken root mounted and then suggests using yast to reestablish grub:

Boot from an install medium, escape to a console by Ctrl-Alt-F2
In the bit below replace sdX# by the /dev/sdX# entry where your root fs is
located, f.e. /dev/sda2
Then do:
mount /dev/sdX# /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
yast
This worked for me last time (ext4 rootfs). There might be a simpler way,
but it go me up and running.
Once bootable, I often resolved nvidia X11 issues by just deinstalling then
reinstalling the relevant nvidia driver. Generally I've had no issues with
nvidia except when I've switched the hardware and need new drivers.
I don't find it to be the cause of many woes (tried Radian once for a short
while a decade ago, thought it was worse).

Hello group,
I am trying to evaluate use of fibre channel switched fabric. But I am not able
to get it working (openSUSE Leap 15.1). I would appreciate, if anybody knows
something or where to find (working) instructions.
All instructions I found refer to old/or proprietary drivers/methods (kernel
2.6 or older).
I use following hardware:
-HP branded (AE312 - 60001) QLogic Corp. ISP2432 4G HBA PCIe
-IBM branded (2005-B16) Brocade 200E 16 Port FC switch
-DS14MK2 Disk Shelf
All of those products are EOS and I am not able to get proprietary drivers or
firmware updates.
According to switch config everything looks fine, I even put all devices into
one zone. According to switch configuration, all the targets should be
accessible by the initiators:

Having set up following options for qla2xxx module
ql2xmaxqdepth=16 qlport_down_retry=10 ql2xloginretrycount=30

I get plenty of messages I do not understand, but it contains matching WWPN's

Hi, all --
I have a media server stuffed full of hard drives, and I have to date
been using Knoppix with a Casper partition on a USB drive to run it. The
idea was that 1) replacing the boot media should be easy (and I clone the
stick to another every once in a while) and 2) upgrading should be easy
(by just whipping up a fresh stick with the latest version and comparing
my persistence partition files with the new fresh versions) while 3)
maintenance should be simple. It's worked well enough so far, but ...
I'm about to bring another server in-house, and I maybe want just a bit
more than Knoppix, although I still won't have disk slots to spare. I
need the simple stability of LEAP, which will of course get updates
regularly anyway, and wonder about running on a thumb drive in the same
way. This one will run MySQL/Maria, probably run a web server, and
will handle email and need at least a basic forwarding MTA if not the
real thing.
I imagine that I'd want to run without swap (*gasp* yes, that discussion
again ;-) and figure I'm stuck with content changes right in the live OS
rather than in an overlay volume. Does that sound right, or is there a
LEAP live image (no, I haven't gone looking yet) that can UNIONFS on top
in the same way?
TIA & HANW
:-D

Hi
For ordinary lazy users like me who are not interested in or capable of system admin as a daily chore, should there not be the possibility of a section in Yast2 or Systemsettings where some standard user friendly housekeeping functions (e.g. flushing tmp folders, vacuuming journals etc) could be activated/configured to run at startup/shutdown rather than have to scour the net for solutions. For many like me, the computer should be doing more work with stuff that could be automated.
I've just hit the "system disk full" message when running "zypper", it would have been better if a "disk getting full" message was displayed at login so i could have dealt with it.
Any thoughts?
regards
Ian
