minor device number: t = type u = unit (upper bits split off from lower) s = slice (assuming only 8 slices) 0 noslice 1 whole disk 2-5 s1,s2,s3,s4 6-8 unused p = partition - = cannot be used tttttttu uuusssss -------- uuuuuppp minor layout for disks 11111111 11111111 -------- 11111111 mask for uminor Our only hope as far as I can tell is to take the upper two bits of the slice (bits 19 and 20) and use them for the partition instead. As far as I can tell, only slices 0-5 are used, requiring only 3 bits. Can someone check my work? Are bits 19 and 20 unused by any disk devices? -Matt Matthew Dillon <dil...@backplane.com> To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
