I've been told (by Jakob) that the limit of 12 disks per md device is just a typo in the code. I'm trying to make a 14-drive linear array. I tried changing MAX_REAL from 12 to 14 in md_k.h (and then even recompiled raidtools) but mkraid still complains about the limit being 12. is there any way around this (safely)? ps i also tried nesting 2 md's inside one....locked up the machine, so i don't feel good about that approach. i'm using 2.2.15 Eldon
