I have just set up a new server with the following configuration : sda1 & sdb1 as md0 (raid 1) for /boot sda2 & sdb 2 as md1 (raid 1) for / unfortunately, a few days after the server is running, I found I made a mistake. I setup the md1 as raid0 rather than raid1. So I have to convert the md1 from the mistakened raid 0 back to raid 1. What should I do to fix my problem?? I'm using redhat-9 with two xeons. Boot manager : grub. -Jason - 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
