[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] dd to copy a partition?

by Lew Wolfgang

Hi Folks, One of my acolytes reported that she used dd to copy one disk partition to another partition on the same disk, as in: dd if=/dev/sda1 of=/dev/sda2 She said it failed, but was a little fuzzy about exactly what happened (I wasn't there), just that the destination partition appeared to be "empty" after the operation. I don't know how she made that determination. I've been doing UNIX stuff for a long time but I never would have thought to use dd in this fashion. Maybe instinct? But assuming that the two partitions are exactly the same size, what could possibly go wrong? I think she was using 42.3, probably with ext4. Definitely not btrfs, if that matters.

[opensuse] Leap 15 live

by jdd＠dodin.org

May be you know this already, but Leap 15 is also available as a wonderful live: https://download.opensuse.org/distribution/leap/15.0/live/ wonderful, because it's taking all the available room on a usb device. Yes, it takes all the room of, say, a 16Gb usb pen (preferably usb3), so all what you do is written, you can even make an update. great!! it's a small iso, under 1Gb, and after that it's "overlayed", I guess some sort of snapshot, and all the rest is written on ext4 partition seems to even be installable, that is there is an "install" icon on the desktop (not tested yet) seems to be a very good solution to my portable install... thanks all! jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
