While shutting down a server I get errors in the console regarding raid device md127. I only get these errors while shutting down. The server boots up normally without errors and /proc/mdstat shows only healthy arrays.
This is the error I'm getting while shutting down the server.
Code:
Stopping block device availabillity: Deactivating block devices:
[UMOUNT]: unmounting storage_vg0-storage01 (dm-9) mounted on /STOR01... done

[MD]: deactivating raid5 device md1... skipping

If the system is up the link exists.
