One oddity has already come to light. My /proc/mdstat says md2 : active raid5 sdb7[0] hda5[3] sda7[1] 19631104 blocks super 1.2 level 5, 64k chunk, algorithm 2 [3/3] [UUU] md1 : active raid5 sda6[0] hdc5[3] sdb6[1] 76807296 blocks super 1.2 level 5, 64k chunk, algorithm 2 [3/3] [UUU] hda5 and hdc5 look odd. Indeed, --examine says Number Major Minor RaidDevice State 0 8 6 0 active sync /dev/sda6 1 8 22 1 active sync /dev/sdb6 3 22 5 2 active sync /dev/hdc5 Number Major Minor RaidDevice State 0 8 23 0 active sync /dev/sdb7 1 8 7 1 active sync /dev/sda7 3 3 5 2 active sync /dev/hda5 0, 1, and *3*. Where has number 2 gone? (And how does `Number' differ from `RaidDevice'? Why have both?) -- `He accused the FSF of being "something of a hypocrit", which shows that he neither understands hypocrisy nor can spell.' --- jimmybgood
