Given this is "only" a single sector error I would keep it running as long as you can physically install the new drive and only then take it offline. At least theoretically, it may be possible to force the rewrite of this sector and use the spare sectors of the disk, but I'm not 100% sure if a simple md check would already trigger it - usually you need to write "new" data to defective sectors to force the drive's firmware to use the spare sectors. But given the replacement disk should arrive soon, I would not act before that and run with a degraded RAID5 until then. I'm a bit more worried about the RAID0 here, do you run RAID0 on top of RAID5 or what is the exact set-up? cheers Carsten -- 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
