Including such things as mdadm.conf file, crontab -l, plus scripts that they use to check the smart data and the array, mdadm daemon parameters and anything else that is relevant to checking and maintaining an array? I'm running the mdmonitor script at startup and a sample mdadm.conf (one of 3 machines) looks like: MAILADDR cousins@limpet-gb.umeoce.maine.edu ARRAY /dev/md0 level=raid5 num-devices=3 UUID=39d07542:f3c97e69:fbb63d9d:64a052d3 devices=/dev/sdb1,/dev/sdc1,/dev/sdd1 These are SATA drives and except for the one machine that has a 3Ware 8506 card in it I haven't been able to get SMART programs to do anything with these drives. How do others deal with this? Thanks, Steve
