How much does my volume group use of my hard drive?
Clash Royale CLAN TAG#URR8PPP
I want to know how much space of my hard drive is being used in the hard drive , let me explain:
My first hard drive is /dev/sda and the second one is /dev/sdb each one of them has a logical voume and they are in the same volume group, i can easily know how much of this volume group is used , but how much of each drive is used ? how does the lvm spread data across those volumes ?
linux lvm hard-disk

You can use pvs to show all the segments in your physical volumes and the logical volumes they contain, which will allow you to get a good idea of how your devices are used:
sudo pvs --segments -o +lv_name
This will show something like
PV VG Fmt Attr PSize PFree Start SSize LV
/dev/sda1 vg-fast lvm2 a-- 119.24g 23.24g 0 16384 root
/dev/sda1 vg-fast lvm2 a-- 119.24g 23.24g 16384 4096
/dev/sda1 vg-fast lvm2 a-- 119.24g 23.24g 20480 8192 usrlocal
/dev/sda1 vg-fast lvm2 a-- 119.24g 23.24g 28672 1853
which shows that my /dev/sda1 PV, which is part of the vg-fast VG, is split into four segments, two of which are unused, and two of which are used respectively for the LVs root and usrlocal.
