What I did was add a couple of 'cat /proc/mdstat' commands where the script was failing. At Point 1 above, I got: ++ cat /proc/mdstat Personalities : [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md127 : inactive md0[0](S) 19904 blocks md0 : active raid1 loop1[1] loop0[0] 20000 blocks super non-persistent [2/2] [UU] [==>..................] resync = 12.5% (2688/20000) finish=0.1min speed=2688K/sec The line with resync looked suspicious so at that point I added a 'sleep 10' command. The test now passes. The full log is at http://anduin.linuxfromscratch.org/~bdubbs/files/mdadm-test1.log Does anyone know what is going on to need this sleep in order for this test to pass?It sounds to like the thing hangs if you try to stop the array before the resync completes. That could be a race in the kernel code.
Thanks. I'll try a different kernel version and report back. The above was tested with kernel version 4.2.0.
