A great deal of time may go by between when mmp_init() is called and
the MMP thread starts, particularly if there are bad devices, because
there is I/O checking configs etc. If this time is too long,
(gethrtime() - mmp_last_write) > mmp_fail_ns
at the time the MMP thread starts. If MMP is configured to suspend
the pool, the pool will be suspended immediately.
This can be seen in issue #10838
The value of mmp_last_write doesn't matter before the mmp thread
starts. To give the MMP thread time to issue and land MMP writes,
initialize mmp_last_write when the MMP thread starts.
