Retrieving disks by logical volume programmatically

[Laur_1]

Hello,

I'm trying to get disks by logical volume bit i don't see another solution that parsing lvdisplay output.
Anybody have another solution.
Thanks,
Christel

you can use pvdisplay to see if the disk is in use by LVM.

If you want to use C, check out pstat(2):

$man pstat

Thanks for you quick response.
I have already try to use pstat_getlv but this function doesn't get names of disk or i need to have them.
Do you known another function on pstat() that return names of disk.

pstat_getdisk()
