I have a PowerPC based NAS device that was damaged by a recent a brownout. The drives in the array are fine, but the device's firmware was corrupted. My first attempt to assemble the array on my x86 system failed due to the endian differences. After applying this patch, the mdadm examine command worked perfectly. As of yet, I have not attempted to update the superblocks. I would like to leave the original superblocks intact so that I can reinstall the drives in my NAS device when it is repaired. Is it possible to assemble the array without overwriting the superblocks? -Brent ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
