So percentages now include unused blocks, instead of being derived from
only blocks in use.
This is a bit inconsistent with tracebd.py, where we show ops as
percentages of all ops, but it's more useful:
- mdir+btree+data gives you the total usage, which is useful if you want
to know how full disk is. You can't get this info from in-use
percentages.
Note that total field is sticking around, so you can show the total
usage directly if you provide your own title string:
$ ./scripts/dbgbmap.py disk \
--title="bd %(block_size)sx%(block_count)s, %(total_percent)s"
- You can derive the in-use percentages from total percentages if you
need them: in-use-mdir = mdir/(mdir+btree+data).
Maybe this should be added to the --title fields, but I can't think of
a good name at the moment...
Attempting to make tracebd.py consistent with dbgbmap.py doesn't really
make sense either: Showing op percentages of total bmap will usually be
an extremely small number.
At least dbgbmap.py is consistent with tracebd.py's --wear percentage,
which is out of all erase state in the bmap.
