Still, that's news, and this is the first RAID-6 snapshot that isn't *known* to be broken :) I can at least mount filesystems, read and write data, reboot the system and have the data still there, with 1 or 2 disks lost, and do a reconstruction once the drives are added back in. New development snapshot at: ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/raid6-20031224-experimental.tar.gz Please test it out and let me know how badly it sucks :) At some point I'll try to run some benchmarks. There is also a lot of optimization still to be done. -hpa [And again, thanks to Penguin Computing for donating a test system, without which this would never have happened.] -- at work, in private!
