Thanks, The two cluster nodes are running on the same host. On the issue of multiplexing, was mostly a curiosity. For testing, I do not care to have to manually link and unlink the PCI device. Moreover, is having a problem with the mailing list? For some time I did not write and since I was not receiving emails from October last year, I signed up again with the same account that I was using before; but since 9 April that I do not receive emails from the list. Interestingly I got your reply but did not get the email I sent to the list. Today I wrote an email to the Pacemaker list with the same account I used to sign up here, and I received it with no problems. Thanks for your reply.
