[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] Can not send email using postfix on Bell, probably port 25 blocked.

by Carlos E. R.

Hi, I can no longer send email "normally", I get: status=deferred (connect to mail.gmx.es[212.227.17.174]:25: Connection timed out) on all mail accounts. My guess that suddenly Bell figured out it should block me or port 25 outgoing. Stupid! :-( So I told Thunderbird to send without using postfix, and that apparently works (if you see this, it works), but I want to keep using postfix. TH is using port 465, SSL/TLS, and password. So, in "/etc/postfix/sender_relayhost" I change this entry: robin.listas(a)gmx.es [mail.gmx.es] to this: robin.listas(a)gmx.es [mail.gmx.es]:submission And then I get this on the log: #<2.6> 2018-09-19 19:55:09 Legolas postfix 2044 - - SMTPS wrappermode (TCP port 465) requires setting "smtp_tls_wrappermode = yes", and "smtp_tls_security_level = encrypt" (or stronger) So I do what it says, then I get this on the log: <2.6> 2018-09-19 20:21:50 Legolas postfix 4065 - - C9A36E309E: to=<opensuse(a)opensuse.org>, relay=mail.gmx.es[212.227.17.174]:587, delay=13119, delays=13118/0.5/0.47/0, dsn=4.7.5, status=deferred (Cannot start TLS: handshake failure) <2.6> 2018-09-19 20:21:50 Legolas postfix 4068 - - SSL_connect error to mail.gmx.es[212.227.17.184]:587: -1 <2.4> 2018-09-19 20:21:50 Legolas postfix 4068 - - warning: TLS library problem: error:1408F10B:SSL routines:ssl3_get_record:wrong version number:ssl/record/ssl3_record.c:252: <2.6> 2018-09-19 20:21:50 Legolas postfix 4068 - - 8AEF1E309F: to=<opensuse(a)opensuse.org>, relay=mail.gmx.es[212.227.17.184]:587, delay=12654, delays=12653/0.7/0.45/0, dsn=4.7.5, status=deferred (Cannot start TLS: handshake failure) So what can I do? it seems a bug in a library, right? -- Cheers / Saludos, Carlos E.

[opensuse] No keyboard backlight since 4.18.x kernels

by Albert Oszkó

Hi all, My problem is in the subject. I even cannot find anymore where ccould I set it. I have two ASUS laptops, from the K501U series, but they are non identical. Keyboard backlight is lost on both of them. The last 4.17.x kernel had/has keyboard light. I waited for updates but with the coming of 4.18.6 kernel the lights are still lost. Albert

[opensuse] help for downloading xpi from addons.mozilla.org site

by Istvan Gabor

Hello: I would like to download (not to install) screengrab xpi with seamonkey web browser because I want to have the xpi file with its original name locally. When I visit the download page https://addons.mozilla.org/en-US/firefox/addon/screengrab-fix-version/versi… with my seamonkey web browser I cannot find any download link to the xpi files. I see only big green buttons with the message "Only with Firefox — Get Firefox Now!", and these buttons direct me to firefox download page. What I want is to save the xpi for later use. Why doesn't the addons page allow the download of the xpi files with different browsers? How can I find out the xpi download links?
