[lvm-devel] wishlist: Two lvm2app pv and lv properties still needed



When using lvm2app function calls to retrieve physical volume segment 
properties there seems to be no way the get the "lv_name" to tie each segment 
of the pv to an lv. For instance like this:

pvs --segments -o+lv_name
  PV         VG    Fmt  Attr PSize   PFree   Start SSize LV   
  /dev/sdh1  local lvm2 a-   768.00m 512.00m     0     1      
  /dev/sdh1  local lvm2 a-   768.00m 512.00m     1     1 lvol1
  /dev/sdh1  local lvm2 a-   768.00m 512.00m     2     1      
  /dev/sdi1  local lvm2 a-   768.00m      0      0     3 lvol2

The same seems to apply to getting lv segments properties and their 
asscociated devices.   Like this:

 lvs -o+devices
  LV    VG    Attr   LSize    Devices
  lvol1 local -wi-a- 256.00m  /dev/sdh1(1)
  lvol2 local -wi-a- 768.00m  /dev/sdi1(0)

It would be great if those two things, esp. the second one could be 
implemented. 

Thank you
