Here is some more info.... When I create the RAID5 using: sudo mdadm --create --verbose /dev/md2 --chunk=512 --level=raid5 --raid-devices=3 /dev/sde /dev/sdf /dev/sdg it shows: mdadm: layout defaults to left-symmetric mdadm: layout defaults to left-symmetric mdadm: layout defaults to left-symmetric mdadm: layout defaults to left-symmetric mdadm: layout defaults to left-symmetric mdadm: size set to 1465138176K mdadm: Defaulting to version 1.1 metadata mdadm: array /dev/md2 started. So great, the array is created and started. Then I cat /proc/mdstat and see: Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] md2 : active raid5 sdg[3] sdf[1] sde[0] 2930276352 blocks super 1.1 level 5, 512k chunk, algorithm 2 [3/2] [UU_] [>....................] recovery = 0.0% (0/1465138176) finish=201456499.2min speed=0K/sec After about 5 minutes, I try to cat /proc/mdstat again and it just freezes and sits there with the cursor flashing. At this point, I can do anything with mdadm, not even like a --detail on another array on the system. Just sits there and flashes. I've tried with a bunch of different disks and same thing all the time. Here is a section from my kern.log.
