Have you tried mdadm --assemble --force /dev/md0 /dev/sd[bcdefghijklmnop]1 ?? Actually, it occurs to me that that might not do the best thing if 4 drives disappeared at exactly the same time (though it is unlikely that you would notice) You should probably use mdadm --create /dev/md0 -f -l5 -n15 -c32 /dev/sd[bcdefghijklmnop]1 This is assuming that e,f,g,h were in that order in the array before they died. The '-f' is quite important - it tells mdadm not recover a spare, but to resync the parity blocks.
