Good so far....now for the problem.... Problems Area ----------------------- Using mdadm I failed to create /dev/md1 in raid 1 (mirror). /dev/sda2 & /dev/sdb2 where part of this set. I get this error: mdadm: cannot open device /dev/sda2: Device or resource busy. I booted from rescue CD, and ran the mdam command to create /dev/md1 ... and it worked! I let the raid sync. When I reboot, I get this error: mdadm: cannot open device /dev/sda2: Device or resource busy. mdadm: /dev/sda2 has no superblock - assembly aborted How to do I solve this? Your help will be appreciated.
