C.4.1. Key Characteristics
This example configuration has the following key characteristics:
•
Fencing device — An APC MasterSwitch (single-switch configuration). Refer to Table C-11 for
switch information.
•
Number of GFS nodes — 3. Refer to Table C-12 for node information.
•
Number of lock server nodes — 1. The lock server is run on one of the GFS nodes (embedded).
Refer to Table C-13 for node information.
•
Locking protocol — LOCK_GULM. The LOCK_GULM server is run on the node that is desig-
nated as a lock server node.
•
Number of shared storage devices — 2. Refer to Table C-14 for storage device information.
•
Number of file systems — 2.
•
File system names —
gfs01
and
gfs02
.
•
File system mounting — Each GFS node mounts the two file systems.
•
Cluster name —
alpha
.
