Comment 10 for bug 1890470

I believe I have root caused the problem thanks to many hints from Aurelien and a subtle hint from a google search [0]

The key to the problem is the error:
"Aug 5 07:24:10 juju-1e2915-4-lxd-13 crmd[14520]: error: Failed to retrieve meta-data for ocf:percona:mysql_monitor"

This error is much different from an actual check of mysql that fails or when the file is missing.

From [0] the suggestion "Could it be as simple as [the ocf file] bit set (for the user)?"

Yes. Yes it can. Percona copies the mysql_monitor file early but does not set the execution bit [1].

Doing some more verification then a fix will be on the way.
