i tried this but mkraid still gives the same error of "a maximum of 12
disks is supported."
i set MD_SB_DISKS_WORDS to 480 to give me 15 disks.
does anyone have more detailed instructions?
looking in parser.c i see where that should have worked, but i guess i'm
missing something. it parses down to /dev/hdn which is my 13th disk and
then gives the error, so somehow MD_SB_DISKS is still 12 not 15. weird.
i did a "make install" for raidtools and verified that it updated the
binaries.
