checking allocated disk space

[pixel fairy]

trying to see how much space is allocated, not actually used in all the qubes. is there an easy command for this? something like qvm-volume info but for all the qubes?

What about "PFree" in output of "pvs"?

What about "PFree" in output of "pvs"?

not what i was looking for either. cant just add up all of lvs because of different kinds of ephemeral volumes. heres a script to just add up all the -root (for template) and -private volumes.

#!/usr/bin/env python3

import subprocess

# older python doesnt have capture_output in subprocess.run
output = subprocess.check_output(['sudo','lvs'], universal_newlines=True)
lines = output.split('\n')

allocated = 0.0

for line in lines:
    l = line.split()

    # headers and the empty line at the end
    if len(l) < 3:
        continue

    name = l[0]
    size = l[3]

    # we only care about vm- volumes
    if name[:2] != "vm":
        continue

    # we only care about persistent volumes, -root and -private
    if name[-5:] != "-root" and name[-8:] != "-private":
        continue

    # lop of the g at the end. check for G in case lvs output changes
    if size[-1] != 'g' and size[-1] != 'G':
        print(name,size,"size is not in gigs. rewrite script")
        exit(1)

    size = float(size[:-1])
    allocated += size

    print("{:7.2f} {}".format(size,name))

print("{:7.2f} total".format(allocated))
