The default timeout for external processes is 45 seconds, after which
LINSTOR sends a termination signal to the process (SIGTERM on Linux). If
the process does not disappear within 15 seconds after receiving the
signal, LINSTOR attempts a forced process termination (SIGKILL on
Linux). It will then wait for another 5 seconds for the process to
disappear, and if it does not, it assumes that the OS kernel does not
work properly (e.g., because the external process is stuck in a syscall
in an uninterruptible sleep on I/O) and resumes as if the process had
ended, abandoning the external process.
That should normally be enough for the external processes executed by
LINSTOR to complete normally.
