It looks like there is some kernel bug/limitation
that may cause invalid table load processing:
dmsetup load LVMTEST-LV1
device-mapper: reload ioctl on LVMTEST-LV1 failed: Invalid argument
md/raid:mdX: reshape_position too early for auto-recovery - aborting.
md: pers->run() failed ...
device-mapper: table: 253:38: raid: Failed to run raid array (-EINVAL)
device-mapper: ioctl: error adding target to table
However ATM there is not much we can do then make delays bigger.
TODO: fixing md core...
