I'm thinking about changing the chunk size on one of my arrays in order to potentially improve performance. The man page rather suggests -c is a vlaid option under Grow mode, although it doesn't specifically say mdadm supports it under --grow. Is it indeed supported under mdadm 2.6.7.2 and kernel 2.6.26-2? Assuming so, I would like to know a bit more about the change before issuing the command. Speficialy, what are the details of the process? Does the entire (RAID 6) array have to be re-written, such as is the case with adding a drive to the array? Does the recovery start immediately? Can it be interrupted and then continue at a later time? -- 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
