Hi everyone. I have attempted to find out the answer to this myself,
however I have not found information that satisfactorily answers the
question of whether LVM supports mirror read balancing, i.e., reads from
both mirrors when the volumes are in sync.
The output below would seem to indicate that reads are not balanced, so
I was hoping someone could let me know if there is a configuration
change I can make to enable this feature.
Thanks --
Shaun.
