[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] Create live 15.1 USB

by James Knott

I'd like to create a live 15.1 on a USB stick. Are there any official procedures? Please note, I want to create a usable system, not an install system. I already have one of those. A search turns up some procedures for Windows, but not Linux. I'd rather use Linux. tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] kde, removed desktop symbols (picture) cached

by Simon Becherer

Hi, i am wondering about how / where kde will cache desktop symbols, because it will show them even if the original source picture is removed: i have a "virtual-machine-management1" desktop entry. with "Icon=yast-vm-management" it shows a monitor and some tools it seems, that this picture was in some update (i use tumbleweed) removed. because if i open properties it will show a other symbol (a white animal at green background). i have more than one computers installed similar, an at one of them also on desktop there is now (i have no idea why) shown the symbol which i see when i open with right mouse click "properties" (animal) in properties, there should normally shown the same symbol i see at the desktop. but at all except one computer i see the old symbol at desktop and the animal symbol at properties. see here: https://paste.opensuse.org/83344057 so my questions are: 1) why is the old symbol still shown even if it seems to be removed (i could not find it actually on my computer by searching for "*yast-vm-management*" in /usr and in /home 2) where is it stored ? 3) how (what symbol) did kde assign a other symbol if the original is removed with other words, when in the desktop entry file is a "non existing" name of a symbol. simoN -- www.becherer.de -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] On this momentous eve, would be nice if 15.0 was extended until 15.2 was ready...

by David C. Rankin

All (devs), Here is to wishful thinking. It would be very nice to extend 15.0 updates until 15.2 is out to avoid problems like supported vbox 5.2.34+ triggering 4 error dialogs every boot with the 15.1 kernel modules built on the also supported 6.x versions along with a few additional intermediate issues.

[opensuse] adobe reader 9.5 in Leap 15.1

by Istvan Gabor

Hello: I still need occasionally adobe reader. I installed it according to the description at this github site: cho2/Adobe Reader https://gist.github.com/cho2/79964a49a4f5f545853d3ebdfd1efe73 I followed the instructions of msohni (commented Jun 2, 2019) with slight modifications (different old library dir name). Now adobe reader / acroread runs without any error or even warning messages. Unfortunately the program print window doesn't see any configured printer, only "custom" is available. I copied libcups.so.2 (32 bit) from Leap 42.3 as the github site suggests but still no printers shown. There must be something else, maybe something trivial I missed. Any idea would be appreciated on how to solve it. Thanks, Istvan -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] xfs planed to be used for root soon?

by L A Walsh

I was wondering if opensuse was planning to use xfs for its root again, soon? xfs formally has reflink copying and can automatically perform some types of deduplication. It's 1 better than using a hard link since only the data is currently dedupped and 2 copies of the same file can be owned by different people, even though the data is linked. They also have COW, so if you change bytes in the middle, only those bytes need to be written, like 2-1GB files were equal, copied 4k of 1's into the middle of one of the original two files. The space on disk went up by 4k for the new file and its sectors were deduped from the other file. No one would claim perfection, but given the frequent problems with BRTFS, it might yield lower problems. Forgive me if this has already been discussed, but it seemed cool! 'cp' even has support for doing reflnk copies or not. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Squid does not execute squidguard (As it should)

Hello everyone, I have some trouble with Squid and SquidGuard on openSUSE 15.1.
