If I set the default value DEFAULT_USE_WATCHDOG to be 0, what would be happened in sanlock?

Hi, all

Sanlock daemon was monitored by watchdog as default in the code.

With the watchdog monitor on , if the connection(iscsi session, fc and etc.) between one
node with SAN was off, the node that had been added into the lockspace would be reset.

In my experiment, my server had been connected to several SANs, and a cluster that
contained several virtual machines was running in these SANs. If one of these SANs was
disconnected, the server would reboot. In this situation, my virtual machines would be
crashed, and so was the cluster.

I don't want the reset of server when it was disconnected with SAN.

I run the command "sanlock daemon -w 0" to solve this problem. And I also modify
the code in src/sanlock_internal.h, set the default value of DEFAULT_USE_WATCHDOG to be
0.

I am not familiar with source code of sanlock. So what the effect of that if I have run
command "sanlock daemon -w 0"?

Thank you.
