+ | Personalities : [raid0] | ||
+ | md0 : active raid0 sdb[1] sdc[0] | ||
+ | 209584128 blocks super 1.2 512k chunks | ||

+ | Next you have to create a filesystem to use your array | ||
+ | |||
+ | sudo mkfs.ext4 -F /dev/md0 | ||
+ | |||
+ | Note that MD0 is your array sdb1 and sdc2 together. | ||
+ | |||
+ | Now create a mount point on your system like /mnt/md0 or / | ||
+ | |||
+ | sudo mkdir -p /mnt/md0 | ||
+ | |||
+ | After that you are able to mount the new array | ||
+ | |||
+ | sudo mount /dev/md0 /mnt/md0 | ||
+ | |||
+ | Check if it is available by doing: | ||
+ | |||
+ | df -h -x devtmpfs -x tmpfs | ||
+ | |||
+ | To make sure that the array is reassemble every time you boot your system you need to set your configuration of your array in a file / | ||
+ | |||
+ | sudo mdadm --detail --scan | sudo tee -a / | ||
+ | |||
+ | Next update the initramfs by doing a | ||
+ | |||
+ | sudo update-initramfs -u | ||
+ | |||
+ | If you like to auto mount your array at boot you need a entry in your fstab. Edit your fstab like this | ||
+ | |||
+ | echo '/ | ||
+ | That's all, enjoy. | ||
