[arch-general] dmraid package - continued upstream or to move to mdraid?
All, tpowa, As of approximately 8-12 months ago, I was under the impression that upstream dmraid would not continue and that dmraid functionality would move into mdraid. (maybe that was just an arch plan?) Early in the discussion on this list it was noted that not all existing dmraid chipset support was included in the mdraid package. <quote> On Tue, Mar 19, 2013 at 2:40 PM, David C.

I can only speak for myself, but to the best of my knowledge no Arch devs use dmraid, and upstream appears to be dead. Based on that I'd say the best choice would be to move away from dmraid if you can. <snip> -t </quote> I am at the point where I need to rebuild an arch server and must decide whether to continue with dmraid or move to mdraid. Looking at the current dmraid package 10/30/13 by tpowa (https://www.archlinux.org/packages/core/i686/dmraid/) dmraid is still in core. The redhat list makes no reference to dmraid not continuing, so I'm a bit confused about the earlier discussion. At this point is there any information to suggest that dmraid will go away? Also, anyone have negative experience with dmraid and grub2 or dmraid and systemd? -- David C. Rankin, J.D.,P.E.

Hi, I quote from my archboot FAQ: dmraid: The reason is there are so many different hardware components out there. At the moment 1.0.0rc16 is included, with latest fedora patchset, development has been stopped. mdadm supports some isw and ddf fakeraid chipsets. You need to try yourself what works best for you. mdadm does only support ISW and DDF devices up to now. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org

Thanks tpowa, I think there is some bad information in archboot FAQ. dmraid development is currently active (see: dm-devel@redhat.com). So is it just the Fedora patchset that stopped development? The dm-devel list is active - todays topic are "multipath patches 1-9" I'll try for myself, but since I have nvidia fakeraid chipsets that I have used with Arch for the past 4 years, my only option is dmraid because mdraid cannot read chipsets other that Intel. Currently the 201311 Arch install is failing to boot, so I'll have to drop back and try and earlier one. (I'll start a new thread on the failure) - -- David C.
