here's what i've done in the past. you start with two disks, say. then you need more space. ALWAYS add pvs in pairs. install the drives, but break the mirror before you extend the vg. then extend the vg to include one physical drive. then add the second drive, and then mirror. when you mirror the lv, you have the choice of specifying the pv to include.
I've gotten into some cross-mirroring situations not doing this and you end up making a lot more work on the back end.

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?
Thanks in advance for any insight on this process.
