I would like to add that I did two resizing tests: 1) 3 disks, no spare -> 4 disks, no spare 2) 3 disks, 1 spare -> 4 disks, 1 spare The first test went OK, the second failed, as reported in my previous mail. I have noticed a similar problem reported a few months ago on the list. If it helps I can repeat the experiment and report all the details. -Igor Mozetic Please CC to me. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
