the partition remains unused. After assigning all partitions, click Next to select the
available RAID Options.
In this last step, set the le system to use as well as encryption and the mount point for
the RAID volume. After completing the conguration with Finish, see the /dev/md0
device and others indicated with RAID in the expert partitioner.
3.3.2 Troubleshooting
Check the le /proc/mdstat to nd out whether a RAID partition has been damaged.
In the event of a system failure, shut down your Linux system and replace the defective
hard disk with a new one partitioned the same way. Then restart your system and enter
the command mdadm /dev/mdX --add /dev/sdX. Replace 'X' with your partic-
ular device identiers. This integrates the hard disk automatically into the RAID system
and fully reconstructs it.
Note that although you can access all data during the rebuild, you may encounter some
performance issues until the RAID has been fully rebuilt.
