What part of: "You will need to enable the experimental MD_RAID5_RESHAPE config option for this to work." isn't bvious? If you don't want this feature, either don't turn on CONFIG_MD_RAID5_RESHAPE, or don't use the raid5 mdadm reshaping command. This feature might be extremely useful for some people (including me on occasion), but I would not trust it even on my family's fileserver (let alone a corporate one) until it's been through several generations of testing and bugfixing. Cheers, Kyle Moffett -- There is no way to make Linux robust with unreliable memory subsystems, sorry. It would be like trying to make a human more robust with an unreliable O2 supply. Memory just has to work. -- Andi Kleen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
