Hi, You can call stonith_admin, or use the pacemaker fencing client API (used for example by DLM). The API documentation is rudimentary: http://clusterlabs.org/pacemaker/doxygen/Pacemaker-1.1.18/stonith-ng_8h.html Be sure you click on "stonith_api_operations_s" for descriptions of the API functions. Whether you use the API or stonith_admin, pacemaker will not fence twice if a request arrives while another identical request is in progress. > > Thank you for reply. > > S pozdravem Kristián Feldsam > Tel.: +420 773 303 353, +421 944 137 535 > E-mail.: [email protected] > > www.feldhost.cz - FeldHost™ – Hostingové služby > prispôsobíme vám.
