[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] IPSec IKEv2 connection on NetworkManager

by Rui Santos

Hello, I've been trying to create a VPN connection using NetworkManager to an IPSec/IKEv2 PSK endpoint, but I'm not having any success, not even with my search on how to do it, at least with NetworkManager. The VPN endpoint itself is working, as I'm able to connect there, and access remote resources with my android phone (by setting the VPN connection on the Android device). It seems I'm lacking the correct nm plugin for it. Here is what I think the relevant list of software is, that I'm using: - OpenSUSE Leap 15,1 - strongswan-nm-5.8.2-lp151.4.9.1.x86_64 - strongswan-ipsec-5.8.2-lp151.4.9.1.x86_64 - NetworkManager-strongswan-1.4.3-lp151.2.3.x86_64 Is anyone able to help me here, or point me in the right direction? If you require any other information, please let me know.

[opensuse] A big please ...

by Dr.-Ing. Dieter Jurzitza

Dear listmembers, I tried to access my Bugzilla account to review my bugs. However, according to the announcement, my access did not work any more. When I tried to change my password it did not work, I received a statement saying "At this time your password can only be reset by an administrator. To send them a request, go to your Sign-in Help page. Then click the Request help link." but help is no help, it works perfectly as /dev/null. Who the heck is the administrator, does someone here know an email address I could write to so I can get help and re-access my bugzilla account? Thank you very much for any suggestion, best Dieter Jurzitza -- ----------------------------------------------------------- Dr.-Ing.

[opensuse] LUKS decryption password requested multiple times during boot in text mode

by Philippe Andersson

Hello List, We're putting in place LUKS-based filesystem encryption on our systems (GDPR and all that...). On workstations or laptops, where the boot process is graphical thanks to Plymouth, the decryption key is only requested once even when multiple filesystems are encrypted (provided they all use the same password, of course). On physical servers on the other hand, that we configure to boot in text mode (as we need to interact with them remotely over a virtual serial console), we get prompted for the decryption password once for every encrypted device -- which is far from optimal from a usability perspective. Is there any way to get in text mode a behaviour comparable to the one provided in graphical mode (single password prompt, no matter how many devices are encrypted)? TIA Cheers. Bye. Ph.

[opensuse] Test mic?

by Doug McGarrett

Is there some simple way to test a mic connected to the computer via usb port? When trying to set up skype, there was a test protocol, which I failed--it said the mic was not working. I haven't been able to get back to that particular routine again. There must be some way to plug in a mic and have some indication somewhere that it works. San someone please enlighten me?

[opensuse] apache Server Error 500 for .htaccess on localhost

Hello, I am doing something wrong with my apache settings to make work .htaccess in a directory... I hope you can help me :-) I need to have all calls to .html-pages in some subdirectories redirected to my index.php putting the path in a parameter called "wo".
