In the 1.1 series, -P is a deprecated synonym for --cleanup / -C. The
options clear fail counts and resource operation history (for a
specific resource and/or node if specified with -r and/or -N, otherwise
all).

In the 2.0 series, -P is gone. --refresh / -R now does what cleanup
used to; --cleanup / -C now cleans up only resources that have had
failures. In other words, the old --cleanup and new --refresh clean
resource history, forcing a re-probe, regardless of whether a resource
failed or not, whereas the new --cleanup will skip resources that
didn't have failures.

With the low level tools, you can use -r / --resource and/or -N / --
node with crm_resource to limit the clean-up.
