Before setting up Red Hat GFS2, make sure that you have noted the key characteristics of the GFS2 nodes (refer to 節 1.1, “設​​​​​​​定​​​​​​​ GFS2 之​​​​​​​前​​​​​​​”). Also, make sure that the clocks on the GFS2 nodes are synchronized. It is recommended that you use the Network Time Protocol (NTP) software provided with your Red Hat Enterprise Linux distribution.

注意
