Hi all, I've finally been able to shake loose enough time (or more like it, I needed a project or I'd go insane) to get my RAID-6 project relaunched. I now have a development snapshot against linux-2.6.0 and mdadm-1.4.0 available at: ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/raid6-20031220-dontuse.tar.gz This release is "dontuse" because there is some kind of problem with I/O scheduling in degraded mode (both 1- and 2-degraded mode.) As a result, raid6d eventually goes into an infinite loop. However, the data is definitely there -- I can create a filesystem on a raid, and it will still fsck clean after gunning two disks. I suspect that there is some corner case in the RAID-5 code which I haven't understood properly and just blindly copied over, which just doesn't work quite right for RAID-6. Eyeballs on the code is of course appreciated. Unfortunately I have to move house next month, so I'm not sure how much longer I'm going to be able to have a working test setup :) On the other hand, I think the code is getting pretty close to actually working :) Special thanks to Penguin Computing for donating a RAID test system with enough drives to make meaningful RAID-6 testing possible. -hpa -- <hpa@transmeta.com> at work, <hpa@zytor.com> in private!
