    SubjectRe: [RFC] [DRAFT] [udev PATCH] First attempt at vendor RAID support in 2.6
    Hi,

    I just returned from my vacation and checked my emails. That's why the
    response is so late.

    1) FIXME: Does "no array defined" correspond to HPT_T_SINGLEDISK?
    I have to check this but I believe it is so.

    2) FIXME: Is HPT_T_RAID_01_RAID_1 a value that can ever be found?
    I think this is the new style raid-10 format that is supported by hpt374
    and upwards. I do not have such a controller so I cannot verify this.

    3) FIXME: what does HPT_MAGIC_BAD mean?
    You get this if you pull one disk out of a raid-0 array for example. The
    HPT-BIOS detects that the raid is not operational and marks the array as
    bad (writes the HPT_MAGIC_BAD to the remaining disks).

    I have not found any crc or so. But since HPT marks any disks that is
    not in an array as HPT_T_SINGLEDISK or HPT_MAGIC_BAD we should be fine
    unless someone writes some garbage to the superblock.

    The HPT copyrights look fine.

    I am looking forward to see the part that writes the dm configuration so
    that I can integrate it into the evms plugin.

    bye,

    PS: add_disk_to_raidlists() does never return retval!
