So I concocted another thing:
name pct size
------------------------------
data 38.66% 15.43g
home 8.22% 3.28g
sites 33.55% 13.39g
------------------------------ +
total 80.43% 32.11g
reported 80.50% 32.13g
available 19.50% 7.78g
------------------------------ +
full size 100.00% 39.91g
This script will take a thin pool as a parameter (or search for all
existing)
and obtain all non-snapshot volumes.
It then counts the PE usage of all segments of those volumes together.
Then based on the usage % it will calculate the number of extents in
use.
It will turn that into a percentage of the total amount of extents in
the pool.
Then it will calculate the size in use and turn it into a human readable
form based on the LVM xxx.xxs format meaning that megabytes are also
displayed 123.00m with a max of 999.00m but typically you would see
0.99g or 2.23g figures.
Goes upto exa :p.
It obtains the VG PE_size (normally 4MB) for size calculations.
The discrepancy between "total" and "reported" is not yet used but
typically this difference would sit in snapshots...
It would become:
name pct size
------------------------------
data 38.66% 15.43g
home 8.22% 3.28g
sites 33.55% 13.39g
------------------------------ +
total 80.43% 32.11g
unaccounted 0.07% 20.00m
------------------------------ +
reported 80.50% 32.13g
available 19.50% 7.78g
------------------------------ +
full size 100.00% 39.91g
Or something of the kind.
The idea for this thing is of course to be used in reports but you could
also run it manually.
