Review comment:
technically speaking reindex should not be allowed at this point,
because the segment still exists(even if it is MFD), the purpose of reindex
command is to reload missing segments which is not the case here. Also, will
this same behaviour also happen for other segment status, say success or
partially success? @akashrn5 can give some input maybe
