when i use 'mdadm -S /dev/md127', it produce kernel event with no stop
when I plug a disk which has superblock(it used to be a part of a raid5) into computer.
at the same time, I use 'udevadm monitor' to monitor the kernel event.
i use 'cat /proc/mdstat',it show me as below:
Personalities :
md127 : inactive sdc[8](S
976761560 blocks super 1.2
unused devices: <none>
so i use 'mdadm -S /dev/md127' to stop it, this show me that :
mdadm: stopped /dev/md127
but the 'udevadm monitor'begin to show me that without stop!
i copy some messages:
