I was expecting to see 70% utilization on my .snapshot file system here. Why is it only 27%? From this output I can only conclude that I have a lot of room and I don't need to bump up my reserve.

total disk space 170788336 + 18976480 = 189764816 bytes

reserve calculation 189764816 * 10% reservation = 18976480 bytes

snapshot usage 5180276 / 18976480 = 27%

That's 27% of the amount you reserved. I don't know where you got the 70% figure from.

Don't use "snap list" to calculate anything other than which snapshot needs to be deleted first in a crisis.
