Neil, The one below is a fix for the problem we encounter quite often when we try to stop all arrays with mdadm -Ss. The main problem is that mdmon holds open container device and then exits. The time that system make clean up is quite long and mdadm invokes ARRAY_STOP ioctl when device is still opened. Second resolution is to retry ioctl in mdadm after mdmon exits, but closing handle is I what should be done before process exist. Take a look at the patch below: -- Sometimes (~50%) mdadm -Ss cannot stop container as mdmon opens its device and do not close it before exit(). The period between open and release of handle is too long and md is not able stop device. Releasing handle before exit does not block md.
