For an existing mirror, you can use a map file with extendlv to specify the
locations of new partitions added to both copies of the LV.
If you are using chfs directly to extend both the filesystem and the
underlying LV then it is not possible to control precisely where new space
will be allocated.
With mirrored filesystems, I nearly always do an extendlv followed by a
chfs.

you can use map-files with mklvcopy, too
or remove the mirror before extending and use the physical volumes as a
parameter when using mklvcopy again
as a third possibility you could use chpv -a n to prevent some pv to be used
for placement of mirrors

Subject: Mirroring question
Scenario: You have a created a logical volume. After the creating the lv on
one physical volume you then mirror that physical volume to another physical
volume. Say 2 months down the road you have extended that logical volume to
the point where it spills onto another physical volume therefore extending
your mirror over another pv as well.
Question: How can you control which pv the mirror is extended to? Is this
even possible?
