Hello Iain, can you please describe what is the *present* status? > /dev/md0 has been started with 22 drives (out of 24) and 1 spare So in short, you had failure of 3 drives, reassembled it with 22 drives and while you rebuild it again a drive failed? If so, take this last failed drive, clone it to a new drive (e.g. dd_rescue) and continue. (Sorry, but this is by far too much output below for my tired eyes. Sometimes a short description is more helpful).
