Raider converts a single linux system disk in to a software raid 1, 4, 5, 6 or 10 system, in a two-pass simple command.
Worked like a charm on a freshly installed Fedora Core 18 _after_ the patch described at https colon-slash-slash sourceforge.net/p/raider/discussion/help/thread/cb24e9a8/#5ffd/61a2 was applied. I used it to convert my system to RAID-1 (mirror). Great tool, saved several hours of work for me.
Raider is a great software tool. Keep up the good work!
