Can we connect more than 32 disks on a single machine? I tried modifying MAKEDEV but the minor numbers of new ones just get wrapped around (e.g., sd32a becomes major 5 and minor 0, instead of major 4 and minor 256). Investigating further, I found this is in <sys/types.h> #define makedev(x,y) ((dev_t)(((x) << 8) | (y))) /* create dev_t */ So it seems like we're limited to 32 disks. Will really bad things happen if I try to change this? Will devfs handle this correctly? Satoshi
