[opensuse] Raid, Raid6, what file system for good fault tolerance?

by cagsm

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. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Spec'ing a 50 TB dedicated storage subsystem and room to grow?

by Greg Freemyer

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. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Any advise on encrypting a file system for personal data on openSUSE?

by Linux Kamarada

Hi, everyone! Recently, as I told on another thread, I installed openSUSE in dual boot with Windows. I would like to encrypt a partition I use to store my personal files (Documents, Downloads, Pictures, Music and Videos). I want to use a file system that can be mounted read/write on both Linux and Windows. Is there any recommendation/advising/suggestion on which encrypted file system I could use to achieve that? I searched the opensuse and opensuse-factory mailing lists and didn't find any for Leap 42.3 and 15.0. openSUSE docs talks about LUKS, but I googled briefly and LUKS support on Windows is abandonware... Maybe I explain better showing my partition setup: Windows recover partition - 499MB Windows reserved partition - 99MB Windows (C:) - NTFS - 100GB openSUSE (/) - Btrfs - 100GB Personal files (D:) - NTFS - 200GB * Home (/home) - XFS - 30.53GB ** Swap - 16GB * This partition I want to encrypt and have it accessible on both Linux and Windows ** This partition I just want to encrypt Thank you in advance!

[opensuse] How to download .bin and .txt file from Firefox

by don fisher

There are a few firmware files I need to down load to get my wireless running. I thought in Firefox, if you clicked on a file, there was a way to select downloading. Now all I get is a dump in hexedit. Is there something to set up to restore this basic capability?

[opensuse] Question re why part of a magazine article does not print

by Basil Chupin

I printed out this article- https://au.pcmag.com/software/138/guide/the-best-vpn-services-of-2018 but the table at the beginning of the article won't print -- the printing begins with the Heading then skips the table of the various VPNs and continues from "VPNs Keep You Safe Online". I had to use the Firefox Add-on 'Screengrab' to save that table to a file and then printed that *.png file. Any thoughts as to why that table will not print as part of that article but has to be saved as a separate file in order to print it? (Using Leap 15.0 [with kernel 4.17.11-3], Firefox v 60.0.1esr, and the printer is Epson Expression Photo XP-960.)

[opensuse] CANBus experience

by Roger Oberholtzer

Anyone using a CANBus card with openSUSE? We will soon have a MobilEye device that we want to test integrating with our system. And it speaks CANBus. We are on our own to provide the CANBus card. So something that is known to play nice with Linux/openSUSE is what we are looking for. So any suggestions or experiences are welcome. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] no more mp4 (html5) reading on leap 42.3 browsers

by jdd＠dodin.org

I'm not sure if it's related with others threads (about chromium), but since a very short time I'm unable to read mp4 on my leap 43.2 browsers (browsers only) for example this video I just uploaded to my gallery, built with kdenlive and my usual scripts http://dodin.org/piwigo/picture.php?/142551-003_flames/category/7520 I can't read it neither with Firefox nor Chromium I can read Youtube with Firefox, at least this one: https://www.youtube.com/watch?v=ObBKKv13F2E&list=RDObBKKv13F2E&start_radio=1 but the same do not read on Chromium. Also I noticed that I couldn't anymore read Facebook videos with chromium nor Firefox, for example https://www.facebook.com/WelfarmFR/videos/271545503609293/ any idea? thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
