I successfully ddrescued all four drives /dev/sd[j,k,l,m], each to new disk, with no errors reported. I have the copies on /dev/sd[n,o,p,q]. Now if I want to force assemble the three copies with event counts that agree [o,p,q], should I just do: mdadm --assemble --force /dev/md1 /dev/sdo1 /dev/sdp1 /dev/sdq1 Or should I assemble the copies into a new array, say /dev/md2? I'm worried that assembling the copies might merge them into the existing (inactive) array. Is that what's supposed to happen? I'm unclear here. Thanks for your help, Bill
