Hey folks, I didn't find any direct pointers on this issue, so maybe you experts can advice me... I was setting up a system, had only one disk at setup time but wanted to configure raid 1 in advance... so I used mdadm --create /dev/md0 --force --run --level=1 --raid-devices=1 /dev/sda1 to create my array. Now as I have the second disk available, after duplicating the partition table I wanted to add add /dev/sdb1 to the array. But mdadm /dev/md0 -a /dev/sdb1 adds this device as a spare one, so the number of active devices stays 1. I could use the build command to reinitialise the array, but I wonder if there's a way to extend the raiddevice while it's running? Is there any way to arrange this?
