Need help in LVM sample command output

[Nikhil_1]

Hello,

I am trying to understand the output of following commands:

vgdisplay -v
lvdisplay -v
pvdisplay -v

but I do not have a test system to work on these configurations.

I would be very grateful if someone can send me output for following cases:

1. Simple 'concat' type volume
- no RAID functionality
- a volume that spans 2 PVs (PEs from 2 PVs are just concatented to form this LV)
2. Striped volume
3. Mirrored volume
4. Mirrored volume with LE-based striping

I need to reconstruct the LE-PE mapping, so the -v option for the lvdisplay, pvdisplay commands would be really useful!

If the output is too big, could you please email it to me at nikhilimhotmail.com?

With best regards,
Nikhil

oops, in my previous attachment the entry for;

Logical volume simply concatanated over multiple volumes (4) as its keeps growing!

was wrong (it was for an lvol on the distributed [striped+mirrored] lvol). Here is the correct output for a simple logical volume over multiple physical disis.

Thanks a lot! I appreciate your help!
