[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] imagemagick convert

by David C. Rankin

Wow!, ImageMagick is now crippled by default. You have to change security policy to convert a .pdf to a .jpg. I attempted to convert: $ convert 20191030_Gohmert.pdf -resize 151 -quality 90 -background white 20191030_Gohmert_thumb.png convert: not authorized `20191030_Gohmert.pdf' @ error/constitute.c/ReadImage/464. convert: no images defined `20191030_Gohmert_thumb.jpg' @ error/convert.c/ConvertImageCommand/3149. What? I'm not authorized to use convert?? Sadly, it seems that is so: https://stackoverflow.com/questions/42928765/convertnot-authorized-aaaa-err… Changing the security policy file and I can now use it.

[opensuse] Discontinuation Notice on 15.0 - No longer plan to support it until 16.0 released?

by David C. Rankin

All, Just for clarification, in an earlier thread on this list, the plan (likely) was to support 15.0 with updates until the release of 16.0. On the Security and Announce lists, Marcus gave Advance Notice of discontinuation of 15.0 at the end of November. It is no longer the plan to extend 15.0 until 16.0 is release? As it is, that will leave 15.1 as the only release, 15.2 isn't scheduled for release until May?? -- David C.

[opensuse] disable overwriting grub.cfg

by Istvan Gabor

Hello: My question applies to all openSUSE versions that use grub2 and dracut/mkintird. Currently I use Leap 15.1, and 42.2. I do not like the default grub configuration therefore I adjust /boot/grub2/grub.cfg manually. When I update the kernel or use mkinitrd, grub.cfg is regenerated, and my settings are overwritten. How can I disable regeneration of grub.cfg? I want to take care of grub.cfg myself.

[opensuse] Advice for NVIDIA and Tumbleweed

by Roger Oberholtzer

I need to use a GPU/CUDA for some deep learning work. It should result in at least a 100x speedup compared to using the CPU. So, I will be needing to use the NVIDIA drivers instead of Noveau. I have a couple questions: 1. I see that the kernel drivers on https://download.nvidia.com/opensuse/tumbleweed/x86_64/ are for kernel-default-5.3.6-1.1.x86_64, while the current one (on my system) is kernel-default-5.3.7-1.2.x86_64. I know that the NVIDIA stuff is usually a little behind. When doing a zypper dup, has it worked that the kernel does not get updated until all dependencies (e.g. NVIDIA) are present? Or does one need to do something else to keep these two things consistent? 2. Are there any things one should consider related to CUDA? Any kernel options so set? Anyone else compiling/running CUDA code on Tumbleweed? https://en.opensuse.org/SDB:NVIDIA_drivers says a little bit. But I don't see much about this there. TIA for any shared experiences. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
