OK - - - finally have a working system - - - -lots of joys - - - first a dead psu then a cabling issue (the usb3.0 front panel connector on the mobo has a specific installation orientation) and then the mob said there was room for 8 SATA drives and 2 M2 drives - - - well when you use the M2 slots you lose a SATA drive for each - - - lots of joys and time wasted - - - if only these gotchas were easier to find!!! Now I come to the install. First attempt set up 2 raid 1s except now I can't partition the drives second attempt set up 2 drives with some spacer partitions (4.0 MB each) and some 8 partitions set up 2 drives with same spacer partitions and a large /home partition then wanted to make 2 raid arrays - - - - except I'm only allowed to use 2 partitions - - - - one from each member of the array. (There was also complaining that there were 2 /root partitions before I tried to create the array.) Neither of these options is what I want. (This is only some couple hours down the drain - - - argh) So - - - how do I achieve 2 raid 1 arrays? #1 has partitions for /efi, /boot, /root/, swap, /tmp, /var, /usr, /usr/local with a spacer of 4.0 MB between (and before the first and after each) #2 has a partition for /home with a spacer of 4.0 MB between (and before the first and after) The destructions that I have been able to find are - - - - well - - - - they're mostly talking about using LVM - - - - which I have not ever used. So - - - please - - - - what do I do besides abandon my idea? (There must be some kind of mystery step someplace - - - and I can't find it!!!!)
