Olaf Faaland a74259cea0 Initialize mmp_last_write when the mmp thread starts ... 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.
