Does it keep track of which log device corresponds to each mirror device
and make sure that the log on disk X is updated before the data on disk
X? In other words, if you are about to write data to disk 1 that would
cause that section to be flagged as dirty, you have to update the log on
disk 1 first, not the log on disk 2.
The syntax and the fact that the number of logs does not have to equal
the number of mirrors makes me think this is not the case.
