Some of the physical volumes show "Allocatable yes (but
full)" while others don't. How does one relate this to the actual
capacity? THe reason I am confused is that 3 of my PV's show up as
full and each is 1.63 TB. Thus the total full space would come to 4.89
TB. But the sum of full space of all my LV's is only around 3 TB
(based on the output of df)
I've reproduced the outputs of pvdisplay, lvdisplay and df below.
I'm confused! Any pointers?

Hi Rahul,
you really appear to have 6 PV (not three) of 1.63TB each and all that storage space is assigned to the VG euclid_highperf_storage .
The VG has three LV defined from it and indeed has free space; using these LV you created three filesystems which have free space too, as Ray just explained.
You have not shown the output of a vgs command but if If you issue it you should see something like this:
#vgs
VG #PV #LV #SN Attr VSize VFree
euclid_highperf_storage 6 3 0 wz--n- 9.8T 1.22T
and so you still have 1.22 TB of free space to use
some math...
Details from pvdisplay:
PE Size (KByte) 4096 = 4MB
VG Name euclid_highperf_storage
Total PE= 428351*6 = 2570106*4MB = 10280424 MB = 9.8TB
total Free PE: 38140+140607+140607 = 319354*4MB = 1277416M = 1.22 TB
total Allocated PE: 428351*3+390211+287744+287744 = 2250752*4MB = 9003008 MB = 8.58 TB
Details from lvdisplay:
Current LE 1572864+153600+524288 = 2250752
exactly like the Allocated PE in pvdisplay
Best regards,
Giorgio.
