Resolution

  • Check pf9 user permissions.

# lslogins pf9
# chage -l pf9
# sudo -l -U pf9
# ls -l /etc/sudoers /etc/sudoers.d/*
# grep "^pf9:" /etc/passwd /etc/shadow
# namei -l /var/opt/pf9/hostagent/data.conf

  • If there is any issue with the pf9 user account and sudoers, fix those permissions.
