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@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
