    dm raid: support raid0 with missing metadata devices · 9e7d9367
    Heinz Mauelshagen authored
    The raid0 MD personality does not start a raid0 array with any of its
    data devices missing.
    dm-raid was removing data/metadata device pairs unconditionally if it
    failed to read a superblock off the respective metadata device of such
    pair, resulting in failure to start arrays with the raid0 personality.
    Avoid removing any data/metadata device pairs in case of raid0
    (e.g. lvm2 segment type 'raid0_meta') thus allowing MD to start the
    Also, avoid region size validation for raid0.
