Hi!
I want to monitor rbd image size to enable enlager size when use percentage
above 80%.
I find a way with `rbd du`:
total=$(rbd du $rbd_name | grep $rbd_name | awk '{print $2}')
used=$(rbd du $rbd_name | grep $rbd_name | awk '{print $3}')
percentage=((used/total))
But in this way, it speed a lot time since fast-diff do not enable.
Is there a better way to check this?
Thanks
