I actually have a system with a failed drive in it now. :-) Whenever the erronous parts of the disk is read, it properly takes the=20= disk out of service and tells about the raid being degraded. However if I reboot, the drive with errors is back in business and used=20= as master of the array. I'm not sure how this is supposed to work, but I guess we at least need=20= limited support for metadata write so we can tell the "controller", and=20= ourselves about the state of our disks. I hope you will retain the online rebuild feature when this is done? I can live without support for configuring RAIDs, but online rebuild=20 would be tough to be without. Having to go to BIOS for rebuild and wait=20= for an hour before the system can be online again is a nightmare :-) Or do you think this is a job for vendor supplied management tools?
